Does Synthetic Fertilizer Kill Soil Microbes? The answer will surprise you.

[@musictech85]

Good information however it fails to recognize the symbiotic relationships between plants and soil microbes (bacteria, fungi, archea, protazoa, nematodes, microarthropods). If you use synthetic fertilizer, yes it will feed the plants and the microbes. However, they will not form tight symbiotic relationships to get what they need from eachother. As soon as you stop using synthetic fertilizer, the plants and microbes will suffer. Whereas with organic fertilizers, they will be stronger together and can survive pests, deseases and lack of nutrients for much longer. Ask yourself, do I want a bunch of freeloading plants and microbes that will die without constant fertilizing? Or do I want to build a strong, healthy ecosystem that will live on with or without me?

Fair comment mate, but it is time consuming & not always easy to build up a well structured soil for crops, gardens, tree planting, landscaping, etc, without using some form of fertilisers, organic or not to help supplement the effort while building that structure.

Chemical fertilizers CAN kill soil microbes. Since it is hard to control the true application rate of chemical fertilizers, excess nitrogen converts into ammonia which kills microbes. Organic fertilizers are considered a long term slow release method. You need 30 parts of organic carbon to one part of nitrogen. Microbes need both in the proper amounts. Chemical fertilizers - 2L of sugary soda every day Organic fertilizers - steak dinners every day.

Farmers also apply fertilizer to acres of land whereas typical homeowners have small plots or containers. I did say hard. I didn't say impossible lol If you buy a bag of granular fertilizer, it is not truly mixed homogenously. Even the factory cannot make it uniform, but close. I tried following precise directions on applying granular fertilizer to start a straw bale garden. Exactly as directed. After a few days I had a severe ammonia smell. Took weeks for it to air out. If I had used a liquid fertilizer, I probably would have had a more homogenous mix and better results. Much better control with liquid fertilizers.

[@xxcolinseymourxx]

Wrong - Ammonia is already a form of nitrogen - it is ammonical nitrogen. other types are nitrate, nitrite and ureic (urea) Nitrogen doesn't convert into ammonia, ammonia converts into nitrate, which is the form plants can take up. Ammonia first converts to nitrite and then to nitrate by the work of soil bacteria as does urea and in the case of organic nitrogen fertilizer there is an extra step and that is the conversion by soil bacterial into inorganic chemical compounds which is the only way plants can take up nutrient. All solid fertilizers have to become soluble before they are of any use. Organic matter in the soil is ideal at around 8 to 10%. Too much makes soil sour. It isn't about whether organic is better than inorganic, it is about best practice where the combination of the two are correctly applied.

Thing about this is, idc what anyone says, the complexity of natural fertilizers such as compost is just going to be better than synthetic fertilizers, no matter how many studies, I believe that even if someone is a biology major, they would agree that the complexity and diversity of organic fertilizers is too much for the human mind to comprehend, as you said, a gram of soil can contain up to a couple billion microbes. And yes, I know it is about the food you give to the microbes, however, just one basic element just isn't enough, take sugar per-instance, yes it feeds microbes, but it doesn't do it for long, nor does it promote complexity and bio-diversity, a correct fertilizer is one that is local and deeply complex with a mixture of slow and fast burning biological materials, and/or browns and greens. Also, to add to that, think of each microbe as having a certain job, the job market won't flourish if there is only one job, so it is VERY self-explanatory. A good example of this is fungi: Since fungi require brown materials, and/or lignan rich materials like wood or dried leaves, something as basic as sugar just wouldn't do, thus the plant would then be deprived of essential mycorrhizal connections. However, I do agree that if a plant is deficient in a certain chemical or element, synthetic fertilizers could be a good temporary fix. Also, at 4:42 , this graph confirms my beliefs, as the population and/or complexity of fungi in the organic field treatments is higher than that of the inorganic field treatments. (However the inorganic field treatments does have SOME fungi.)

I wonder if the nutrients in some types of fertilizer are stereoisomers that end up more effective than other forms with the same chemical formula in practice. Maybe it isn’t enough to matter, but in human biology I’ve seen cases where one stereoisomer could be doubly effective as another simply due to the particular arrangement of atoms in the molecule. But even in such a hypothetical case, there’s no reason that the more effective arrangement couldn’t be in the synthetic fertilizer anyway. It would just be random chance which one is better in each biochemical scenario.

[@nathanmcgrath9038]

It a good question. The answer is it depends. If for instance your soil has a high pH over 7 the ammonium sulfate in fertilizers will be converted into ammonia and yes that will kill your plants and bacteria.

[@MemoryPallace]

Why Organic Soil is Better (For the truth seekers & Free thinkers) 1. Composition and Source: Synthetic Fertilizers: These are chemically manufactured and contain specific, isolated nutrients such as nitrogen (N), phosphorus (P), and potassium (K) in highly concentrated forms. They are often salts and are designed for quick nutrient release. Natural Fertilizers: Derived from organic sources like compost, manure, bone meal, or plant residues. They provide a wide range of nutrients, including trace elements, in more complex, less concentrated forms. 2. Nutrient Release: Synthetic Fertilizers: Provide immediate nutrient availability to plants because they dissolve quickly in water. This can lead to nutrient leaching if not managed properly. Natural Fertilizers: Release nutrients slowly as organic matter decomposes, which aligns more closely with the natural nutrient uptake of plants. 3. Impact on Soil Microbes: Synthetic Fertilizers: Can harm soil microbes by creating an imbalance in the soil food web. High concentrations of nutrients can kill or inhibit beneficial microbes, leading to a dependence on fertilizers for plant growth. Natural Fertilizers: Feed and support soil microbes, promoting a healthy, balanced soil ecosystem. They contribute organic matter, which serves as food for fungi, bacteria, and other soil organisms. 4. Soil Structure: Synthetic Fertilizers: Do not improve soil structure. Over time, repeated use can degrade soil health, reducing organic matter and leading to compaction or erosion. Natural Fertilizers: Add organic matter to the soil, improving its structure, aeration, and water retention. 5. Environmental Impact: Synthetic Fertilizers: Often result in nutrient runoff, which can pollute waterways and contribute to issues like algal blooms and dead zones. Natural Fertilizers: Less likely to cause nutrient runoff because nutrients are released slowly and in a more stable form. 6. Dependency: Synthetic Fertilizers: Can create a dependency cycle where soil becomes less fertile without regular applications, as natural soil fertility declines. Natural Fertilizers: Build long-term soil fertility by enhancing the natural processes of nutrient cycling through the soil food web. (PART 2) In Teeming with Microbes, the authors explain that synthetic NPK (nitrogen, phosphorus, potassium) fertilizers primarily bypass the natural soil food web and provide nutrients directly to plants in a soluble, inorganic form. Microorganisms don't "eat" synthetic NPK fertilizers in the way they process organic matter or natural fertilizers. Here's why: 1. Synthetic Fertilizers Are Pre-Digested Nutrients Synthetic NPK fertilizers are made up of inorganic, water-soluble compounds that are readily available to plants. These nutrients are already in forms that plants can absorb (e.g., ammonium, nitrate, phosphate, and potassium ions). Because these nutrients don’t need to be broken down by microorganisms, the role of microbes in the nutrient cycling process is minimized when synthetic fertilizers are used. 2. Limited Role for Microbes Nitrogen (N): Microorganisms like nitrogen-fixing bacteria play an essential role in converting atmospheric nitrogen into plant-usable forms. However, with synthetic nitrogen fertilizers (e.g., ammonium nitrate or urea), this process is bypassed, potentially reducing the population and activity of nitrogen-fixing bacteria. Phosphorus (P): Phosphorus from synthetic fertilizers is in a highly soluble form (e.g., monoammonium phosphate), so plants absorb it directly. Mycorrhizal fungi, which naturally help plants access phosphorus from organic matter or minerals, become less active when plants no longer rely on them for nutrient acquisition. Potassium (K): Potassium salts in synthetic fertilizers (e.g., potassium chloride) are also immediately available, so soil microorganisms that help release potassium from organic or mineral sources are not needed as much. 3. Impact on Microbial Populations Synthetic fertilizers can harm beneficial microbial populations by: Increasing soil salinity, which can be toxic to microbes. Disrupting the natural nutrient cycling processes that microbes facilitate. Reducing organic matter in the soil (the primary food source for microbes), as synthetic fertilizers don’t contribute organic material. 4. Microbes May Interact Indirectly While microbes don’t "eat" synthetic NPK directly, they may still interact with these nutrients in limited ways. For example: Some microbes may use nitrate or ammonium as a nitrogen source for their own growth, but this is less common compared to their natural role in processing organic nitrogen sources. Excess nitrogen or phosphorus from synthetic fertilizers can lead to imbalances that favor fast-growing, opportunistic microbes (sometimes harmful ones) rather than the diverse, balanced microbial communities in healthy soil. In conclusion, synthetic NPK fertilizers are not a food source for microbes in the same way organic matter or natural fertilizers are. Instead, they bypass microbial processes and can disrupt the soil food web if used excessively or improperly. Teeming with Microbes strongly advocates for working with soil life to create a sustainable, self-sustaining ecosystem, which synthetic fertilizers often undermine.

This is very much an 'it's complicated' topic. Soil microbes are a really broad group that covers fungi, bacteria, and so on. Some form symbiotic relationships, e.g., rhizobia and legumes. The bacteria converts nitrogen from the air into ammonia for the plant to use. Mycorrhizae also form symbiotic relationships with plant roots. They can transport water and nutrients and do a bunch of other things. There's also all the bacteria that are involved in the nitrification process. As well as the ones involved in breaking down organic matter. What's my point? Well excess nitrogen can cause legumes to not form the relationship with bacteria since they have enough nitrogen in the soil. Similar situation with the mycorrhizal relationship but often when talking about phosphorus. If you're dumping a bunch of nitrogen fertilizer on the soil and no organic matter then the decomposer population quickly shrinks. Depending on the type of nitrogen you add, the bacteria responsible for converting it to different forms will multiply. So it is bad? Not necessarily. Bacteria multiply really really fast and will quickly repopulate an area when it's favorable. Also, since at the end of the day nutrients are nutrients you can overdo it with organic or synthetic. Even legumes in specific scenarios grown just for nitrogen and organic matter can lead to excess nitrogen leaching into the water table, waterways and so on.

As someone who studied soil science and plant nutrition at college and put it into practice for several decades it is interesting to read and hear in the gardening world that soil biology pseudo-science is still well alive and kicking. This info here is correct. plants cannot tell the difference. Organic vs inorganic in a one size fits all frame is an over simplification. Enthusiasts of organic very often don't even understand what organic means, assuming anything not manufactured is organic. If its from rock its also inorganic. Do inorganic fertilizers kill microbes? Depends on what inorganic fertilizer it is. Sure ammonia nitrogen will have the earth worms either moving out or dying, while calcium nitrate will have them moving back in in large numbers and both inorganic. If anyone cares about cattle welfare around the world they wont be using bone meal or hoof and horn. If anyone cares about depletion of fish from our oceans they wont be using fish meal or fish emulsion as these are the result of over fishing. Organic matter in the soil, healthy colonies of fungi and good drainage are far more important than if nutrients come from inorganic or organic sources.

While the claim may hold some validity in general contexts, it does not accurately apply to cannabis cultivation and its final product. Organic natural Soil-based farming methods yield a significantly smoother smoke compared to products derived from synthetic processes. The latter, often marketed as safe and effective, fail to match the quality of soil-grown cannabis. This discrepancy likely arises from a combination of factors, including inferior cultivation techniques and inadequate disposal methods for synthetic byproducts.

[@xxcolinseymourxx]

@@bobbybass3586 Lower water content and higher denser dry matter is most likely why. It isn't the actual fertilizer type that makes the difference it is how it is delivered to the plant that counts. Organic has to go through a process in the soil where the microbes convert the organic fertilizer into inorganic chemical compounds which is the only way plants can take up nutrients. This results in slower growth and a harder plant as the plant doesn't receive nutrient in a surge as it might with soluble inorganic fertilizer. It is why fertilizing with inorganic fertilizer needs to be much more precise with measuring and scales, whereas organic fertilizers and manures can be used heavy handed and a large guesswork margin of error. The smoother smoke is most likely achieved from a denser molecular structure in the the leaf and a higher concentration of the cannabinoids which is the magic ingredient. Slower growth and higher dry matter result in better flavour in fruit and veg too. So it isn't the actual type of fertilizer that makes the difference but more the method and growth characteristics. I favour a thoughtful and knowledgeable mix of organic and inorganic for best results. While organic nitrogen isn't difficult to use with good results, adequate levels of potassium is damn near impossible to achieve organically. Personally I cant stand the smell of cannabis being smoked - lots of students live around me and smoke it in their gardens in the evening, it stinks to high heaven.

You missed a very, very important point which is carbon. While it might be ok to apply some synthetic fertilizers in a garden situation providing you are also adding carbon via manure, compost or mulch this is not the case for big Ag as they only use synthetic and no carbon at all. In order for microbes to eat the synthetic nitrogen they also need a carbon source as there diet is 30:1 and so they will eat organic matter and the biotic glues that create soil aggregates and then the soil collapse and once this happens the microbes do die off and when it rains it runs off as soil is hard. Plus this practice puts a lot of carbon into atmosphere, way more than fossil fuels

When a farmer adds synthetic fertilizers he adds carbon in the crop roots and residue from the crop. If he grows a cover crop it is generally 60 to one C:N. He will need to add N to make 10:1 soil organic matter. Synthetic N then helps microbes grow. The carbon comes from the air as CO2.

[@timshirk6261]

That is correct but unfortunately the ratios are way off meaning there is way mor N being applied that carbon going in soil and therefore the soil will collapse. Cover crops can help in a big way. Hybrid GMO corn today will synthesize a lot of CO2 however very little goes for root exudates and most to above ground plant tissues which end up as surface residue which most will oxidize back to atmosphere.

[@cynthiamilbradt9943]

The issue surrounding chemical fertilizer is not so much what it does in the garden, but how it is manufactured. Fertilizer plants are polluting and is fossil fuel intensive. “In 2021, 30 ammonia nitrogen fertilizer plants in the U.S. released 7.7 million pounds of nitrogen pollution into waterways, including 3.9 million pounds of toxic ammonia. This is equivalent to the amount of nitrogen pollution from 62 sewage treatment plants. The production of chemical fertilizer contributes to 0.8% of global greenhouse emissions by pumping heat-trapping gases into the atmosphere, like nitrous oxide and methane. Added to that is the energy required to run the plants. Both ends of the subject need to be factored into the equation. Just for the record, I use small amounts of chemical fertilizers in my own garden on top of a mostly organic approach using wood chips, compost, mulch and worm castings. I am not completely opposed to using chemical fertilizers but I am very aware of what the cost is to our environment.

[@Carlo_B]

of course there are, when you do not fertilize properly. Many farmers still believe that the more you fertilize, the more you will harvest. Heavy metals and other dangerous products can be left even with an incorrect organic fertilization. Plants are not animals, they eat and live in a complete different way. When you spread a fertilizer you are not feeding the plant, you are feeding the soil. Once the fertilizer is converted by microbes and other micro organisms into a form that the plant can absorb, it will be absorbed, but only in the right amount the plant needs. An example: if a tree needs 1 kg of potassium, and you spread in the soil 3 kg of potassium, the pland will absorb only 1 kg. The other 2 kg will remain in the top layer of the soil for many years. if the 1kg of potassium needed was already present, the whole 3 kg will remain in the soil. If you don't know what and how much minerals in the soil are missing, how can you know how much and what type of fertilizer you need? Do not fertilize until you'll get a soil test done.

Do you think synthetic fertiliser fields and gardens become depend on repeated applications whereas natural soil systems create biochemical pathways to naturally liberate mineral elements from rocks and sand? [analogous to antibiotics versus natural immunity]

[@pendlera2959]

"Do you think synthetic fertiliser fields and gardens become depend on repeated applications" Yes, of course. When we harvest crops, we're removing nutrients from that location and transporting them elsewhere. In nature, plants are surrounded by decaying things, including other dead plants, and they get their nutrients from that process. Under cultivation, we generally remove most of those sources and thus have to continually replace them with some kind of additional nutrients, whether synthetic or organic. Even in nature, if things didn't die or poop, plants would starve. "whereas natural soil systems create biochemical pathways to naturally liberate mineral elements from rocks and sand?" There are 2 kinds of nutrients that plants need: micronutrients and macronutrients. Macronutrients are needed in large quantities and get used up quickly. Micronutrients are needed in small quantities and take a long time to get used up. Most minerals in rocks and sand are micronutrients and aren't going to be affected by the application of synthetic macronutrients. "analogous to antibiotics versus natural immunity" I'm not sure what you're referring to here. Antibiotics are chemicals that kill or hinder the growth of bacteria. Some are naturally occuring, such as penicillin. They don't affect your natural immunity because your body still has to fight off an infection even if you take antibiotics. Your body will still be able to recognize and fight off bacteria in the future even if it had help from antibiotics during the first infection. Antibiotics can cause a problem when they wipe out beneficial bacteria, but that's not how fertilizers work in a garden.

[@taxusbaccata6332]

@@pendlera2959 Thank you for the detailed reply. Interesting points. What I am asking though is are organic soil ecosystems self sustaining - can they liberate minerals (including macro NPK) fast enough for plants? They certainly do natural ecosystems but also could do so for agriculture. NPK comes from rocks too and organic material. The antibiotic questions was a comparison, of interest the immune system has much less work to do if antibiotics are started early. [it is known that strep throats and tonsillitis recur more frequently if antibiotics are started in the first 2 days, delayed antibiotics exposes it to the immune system which then creates memory B cells] So in summary I am asking if synthetic fertilisers damage the natural mineral liberation abilities of the soil ecosystem? That is suggested by soil scientists such as Elaine Ingham and Christine Jones.

Continual use of synthetic does change the microbe population in a field. We really know very little about these populations. We have only identified 20% of the species in soil. If a field is left fallow, with no more fertilizer added, it does return to its former self in a few years.

We are barely touching the beginning of understanding what goes on in the rhizosphere so making the statements you make in this video seems very biased and ignorant. Just look at the new understanding of rhizophagy and nitrogen fixation in tricomes as an example. To think that we can manufacture inorganic forms of fertilizer that improve on what natural selection came up with over millions of years is just arrogance. Part of the effects of organic forms of nutrition is the interactions of the soil microbes in the breakdown into plant usable forms that the plants actually have a part in the process. I feel you have done a disservice to the progress finally being made to help regenerate our badly chemically degraded soils. Your choice of the scientific studies you shared was very biased because you chose them to try to prove your point. It makes me wonder if you are being funded in some way by Big Agriculture.

Number of microbes isn't a great metric for soil health, same as if you applied it to, say, gut health. Someone could have a massive number of microbes in their gut but be dying of a c. difficile infection. What's beneficial is a large diversity of microbe species, because different fungi and bacteria provide different ecosystem services (including nitrogen fixation from the air) and the interactions of different microbe species cause them to express different genetics in themselves (quorum sensing) and the plants growing in them. A plant that is able to suck copious dissolved nitrogen in through its roots won't need to form symbiotic relationships with microbes it would otherwise need to supply it, and you miss out on the beneficial side effects of those symbiotic relationships on plant health/resilience and soil structure, such as increased organic matter, which buffers pH, improves water retention and tilth and provides a stable environment for the microbial ecosystem. Everyone knows you shouldn't mix wood chips (high carbon i.e. organic material) into your soil because it robs nitrogen. If you add straight nitrogen to your soil (meaning nitrate or ammonium), you end up robbing organic matter by much the same process: the microbes that bloom from the influx of nitrogen also need carbon, and they'll use up whatever carbon (organic matter) is close by.
