Plant Nutrition 101: All Plant Nutrients and Deficiencies Explained

[@nicholaspanu8735]

I used to be a bodybuilder and obsessed about nutrition and diet. I apply what I learned building my own body, to my garden. (We're more similar that you think in a certain way) I would love a list of matter to add to a compost heap, for certain nutrition issues I.e Nitrogen - comfrey, nettle, lawn clippings.. Carbon - Branches and woody materials.. Calcium - Dandelion leaves.. Iron - Spinach and other dark leaves.. Etcetera... I figure that just like taking a multivitamin and eating crap all day, the soil will not be treated by endless fertiliser. Seems similar to fast food. Good in a crisis but not best practice. You must make the garden "eat" well (compost and mulch) I prefer a holistic approach and treat the soil with organic matter more often with fertiliser. Seems to be working well. I know troubleshooting means using some fertiliser, as issues occur, but I prefer to treat the problem not the symptoms. Just like in bodybuilding, where I started scrawny and finished at 105kg of muscle; The plot on our rental property was a neglected hell of rubble, weeds and 3ft of sand. Been applying permaculture methods to treat the soil up to 4ft deep in places. Healthy soil - healthy food - healthy ecosystem.....its all linked. Brilliant video. Very helpful Now where did I put that molybdenum....

[@falkharvard8722]

I applied this by making a dandelion tea for my lawn. I had tried a comfrey/nettle tea but it only mildly responded. Figured nutrition uptake may be the problem. One week after fertilizing with the dandelion tea, my lawn is lush and verdant again.

Oh wow, what a great video. So many of these deficiencies might appear, at first glance, to be pest damage. For a newbie like me this is invaluable information, thank you! I recently watched a YT video where the "experienced gardener" criticised new gardeners for worrying about every little hole in a leaf, or a leaf that doesn't look right. I love how you take all levels of experience into consideration and actually show that one leaf not looking well can be a big deal. Subscribed, liked and saved. And shared!

[@wordswritteninred7171]

THANK YOU FOR SUCH A VALUABLE VIDEO!!!!! It has been twenty or more years since I have grown a garden. I have forgotten more than I remember. I was taught by my grandma. Now, she didn’t know what deficiency a symptom meant. She just knew what to do to correct it. She was so knowledgeable about gardens. Anyway, I am starting a garden, from scratch. At a house, that had hay fields, cattle, chickens, and, somewhere, a garden. The house sat empty for several years before we bought it. So it is all overgrown. So I have no idea where the garden was located. It has some patches of good soil. But mostly, clay. I have a question, if you might happen to know. Can you get the right nitrates, for a garden, from pond water? I use to breed fish. I understand the cycle of tank water. Ponds are the same…basically. But I don’t know enough about chemistry, to know the answer to this. I keep hearing, to add organic material, and plant nitrogen fixing plants, to help begin to admin the soil. Wondering if pond water would be a help in this. Or would it be like putting fertilizer on the soil. And rain just leach it away? I just now found your channel. This video here, is the best, most informative garden video I have seen. And believe me, I’ve watched plenty! Who knew plants needed chlorine!? Well, you did.lol but doubt many others know!

[@heavymechanic2]

Very few fertilizer products have BORON because it can be toxic if over used. In my experience, its essential for some vegetables such as beet root. A quick remedy is to add 2 tablespoons of Mule Team Borax to hot water to dissolve and add to a sprinkling can and lightly spread the water across 100 sq ft of garden to correct a minor deficiency.. I use a lot of fish/kelp to add micro-nutrients to the soil.

[@adamschwarz270]

Good stuff

[@josephdrach2276]

There are factors to consider when looking at exactly what you use to provide your soil with a full array of nutrients. One of them that was not mentioned was pH. An acid soil that you want to keep acid might get powdered sulfur, magnesium sulfate solution, and calcium sulfate. These things will either be neutral or acid in reaction to the soil and provide Calcium, Sulphur and Magnesium as well. In alkaline soil, they would tend to lower the pH. If you have soil that needs the pH raised a bit and needs Calcium, Magnesium, and sulfur, Dolomitic limestone has both magnesium and calcium in it and Calcium sulfate provides calcium and sulfur. The limestone also raises the pH. The interplay between pH and nutrient availability is something good to understand. This also helps you choose sources of nutrients that go with the pH you have and like or change the pH toward what you want. Calcium Sulphate is also good for loosening hard clay soil and helping repair salt damage. Various organic fertilizers can raise, lower or work well with your existing pH. It's good to learn about these things and the info is readily available. This was a good presentation. I liked the symptoms of deficiencies and how they were portrayed and described.

[@GRasimos]

One thing to also consider, if the soil PH is too high or to low, the different minerals have issues depending on whether or not the PH is high or low. Most plants do well with a ph between 7 and 5.5. Outside of thy range, and issues arise. So the liberal might be there, but it is not accessible due to improper PH. And then we throw biology in the mix, which makes the nutrients available to plant like through what called nutrient cycling. Lost of info to be discussed here. But you do a great job at showing and explaining the different deficiencies through the photos chosen. I commend you. And I give thanks for the info.

[@ph3nriq]

Can you share resources on nutrient cycling? Any authors? Articles? Thanks!!

[@jameswilmot4537]

Good to know. I had trouble growing my pepper plants last year as I used rotted wood in my soil. This caused a yellowing in my pepper plant leaves until I used liquid nettle and comfrey on them, that made them jump out the pots and green up nicely with fruits. These plants appears in my May 2021 update from 5m 40s, when I recorded this I hadn't quite worked it out, I thought it was well rotted fertile decent wood soil lol. I didn't understand my NPK so well not to mention all the other nutrients.

[@Opal.Workshop]

Maybe do a video on pH and how it affects nutrient availability because this is the first thing you should be checking before making any amendments to your medium , it would help explain why certain elements become unavailable if not in their recommended range.

Ammonia for nitrogen. Diammonium phosphate for phosphorous. Banana peels or wood ash for potassium. Three wonderful ingredients for a great fertilizer.

[@peaceydanckwerts]

Useful video. As somebody already commented below, pH can have a significant impact on nutrient availability, but I want to add two other comments. One is the synergy between Calcium and Boron. Plants cannot really benefit from Calcium unless they have adequate Boron, and plants cannot really benefit from Boron, unless they have adequate Calcium. Second point is that Molybdenum is especially important for legumes (as it is part of the process by which the rhizobia can fix atmospheric Nitrogen to make it available to our gardening system), but these rhyzobia ALSO need Cobalt, generally not considered a plant essential nutrient. On my farm, Cobalt is not likely to be short (because I feed it in a supplement to my Livestock) but it might be something to consider if your legumes are not nodulating effectively

[@carmellayates2503]

Thank you Kevin , this was very informative . A big help for my plants is to not misdiagnose if I think there's a problem .

[@EngineerCatPyro]

I know I'm late to the party but I have to say that I was looking for exactly this explanation when I started my search today. I wasted 20 mins of my time with all these random videos that just didn't explain it properly or at least to my understanding. I then came here. Even though I've been a subscriber for a few weeks I didn't look here first. For now on, i'm always coming here first. I learned so much from the other videos here that I really should start here all the time. This was exactly what I needed to learn in more ways than one. Here's why I was searching for this. I picked up some tomato plants from home depot. I've had them for about 7 days and the ones I haven't had a chance to transplant from soil to hydro yet have the lower leaves turning yellow and drying up. (I currently do not have nutrients in the ones I transplanted). I've been giving them tap water every few days. (no nutrients or PH adjustment) My first search to try to find out why said " it's either to much or to little water" WHAT?! How does that help me? Anyway, tomorrow they are getting added to the DWC and i'll be adding the nutrients. I'm hoping the GH 3 part I have takes care of what they need . The PH in my city water is high even after adding nutrients, so I'm adjusting that too. I'm hoping getting them in water with the nutrients will help resolve their issues. Your channel should be called Professor of Epic Gardening or Epic Gardening Master Class.

Thank you EG, this is a really good video. Shows you exactly what to look for in terms of nutrient deficiencies but also the importance of trace elements. This cannot be emphasised enough. Having been in the Diamond Exploration business for over 45 years, over that time I learned that ANY volcanic rock extrusions but in particular Kimberlites (in which diamonds occur), if crushed sufficiently fine enough (say around 0.1mm or less) are sooooooo beneficial to plants when applied as a supplement.

well the sad part is that most of these symptoms are also caused by fungus or bacterial or virus or nematode diseases so what i suggest is to be careful if there are other signs on other parts of the plants example on stem or flowers so that you don't only focus on the symptoms showing on the leaves

[@bigpapi3636]

This is a darn good video. Micro-nutrient deficiencies are interesting in that certain ones are more apt to occur in certain plants and in certain soil conditions and localities. Here in Southern California for instance avocados are prone to zinc deficiency which shows up as rounded as opposed to pointed leaves. On my trees I broadcast Zinc Sulfate at about 1 lb per inch of tree diameter every 4-5 years. I'm really interested in cheating agents like EDTA which should allow plants to take up micronutrients easier. I've used a synthetic called Grow-More in 20-20-20 which is a water soluble product that contains micronutrients as well. It's also available in several different N-P-K ratios depending on the plant need. That product along with elimination of high amounts of interference elements like Chlorine seem to supply a pretty good balance of micronutrients as well as understanding the local water and soil and which Moros are apt to be deficient.

[@epicgardening]

Good tip on the avocados and thanks for the kind words. I too live in SoCal, so you better believe I'm going to take that zinc sulfate tip to heart.

I loved this video. I often am confused about what is wrong with my garden. I get tiny dark spots in my fruit tree leaves and was told by a local nursery it was iron deficiency but that appears incorrect based on the information here...!!?? Also the Word Molybdenum... I was taught to use the following trick to remember how it is pronounced “My Lips are numb” ..... (moe lib de numb). Thank you for this video

[@troyclayton]

If you want to know what's wrong with your plants consult your local university extension service, imo. Mine takes samples for a 10 dollar fee, which they say is just to discourage too many samples, but they talk for free. With a BS in Plant Biology, a pesticide license, and 20 years in the field- I still took samples to those who knew better than I (plants are now just my passion, not my job anymore). Necrotic lesions aren't just from nutrients. edit: I've seen people pump up nutrients so many times because they mistook disease for a nutrient problem. Living in New England, almost every problem I see with fruit trees is disease/site related, not a nutrient issue.

[@why6246]

Interesting vid- but I've learned from soil biologists that the soil has all of those elements- it may not be bioavailable to your plants when there isn't adequate symbiotic interaction between the microbes and roots. The cheapest and best long-term way to benefit your plants is to increase those bacteria and fungi, which will attract all other parts of soil food web (nematodes, arthropods, worms, etc.)To do that, most recommend compost tea and more live roots in the soil (cover crops and even weeds sometimes). Makes sense.

[@khakicam5400]

Depends on your geology and soil age/history. It's pretty cheap at the garden level to do a soil test and balance the minerals in your garden to ensure your veggies, in association with soil biotic processes, are packed full of what your body needs.

So in short: when you buy fertilizer, majority of it is empty filling. Also when you plant flowers and basil under your tomato, you are very meticulously fertilizing your tomato for fruit, your flowers for flowering and your basil for leaves.

Quick question. Would all of these deficiencies be solved by having a good compost? Would composted vegetables, fruits, grass ect. have all of these nutrients?

I don't count nutrients as I have always used organic gardening methods and I don't mean those organic pellets from the store. I just compost and cover with straw. I get some council wood chips and leaves and compost those with urine. I also add wood ash and char to the compost. I rarely have pests. I companion plant because It self seeds a lot. I also grow cover plants that I let die and rot, like raddish, clover and peas. I have had curly leaf on a peach tree last year, but it's come back ok this year, just cut it back hard and got rid of the ants that were spreading it. It was them or harlequin bugs.

[@AlexandreLollini]

If one element is not in the list of nutrients for plants, it's because research has not yet been done on it. Each element is present in the soil profile, if the plant is lacking it is more often because a microbiology element that moves or transform it for the plant is deficient or suppressed or killed or displaced. Some deficiencies are due to the excess of another. Stopping to apply N when fruits fall is a good start. Reducing or removing P from fertilisers is another step to promote soil microbiology. (10sof tons of P in soil per hecare in the first 6in already present) Plants do not mine the nutrients, and do not drink water. Plants use moisture, and recycle nutrients with the help of microbiology. We see effect of a nutrient deficiency it is the result of a problem in soil microbiology, fungi, protozoa, nemathodes, worms etc. Copper is elasticity, if fruit crack, or branches are brittle, copper deficiency. Also Zinc deficiency makes smaller leaves, asymetrical leaves, and reduced or no plant growth at all. Mineral deficiency is preferably addressed by foliar application, while in the soil it's the microbiology deficiency that must be addresses (the plant in good health will then build the soil and its life)

I grow creasote in minnesota which needs toxic soil to help with plant shock so I actually mix in chromium to potting mix and sand recreate caliche toxicity.

[@amywatkins9309]

Thank you! I’m just beginning and learning the needs of the plants is kind of important.

Plant nutrition was my biggest downfall last summer. I didn't amend enough in the right beds. Gonna change that this year so I appreciate this video.

From South Africa. Thank you for a most informative video. I liked that there were plenty of photos to show the results of a deficiency. I am a newby at hydroponics and would really like to see videos about this. I especially want to grow strawberries. What temperature should the water be? It gets pretty hot where I live. Thank you for sharing your knowledge.

[@epicgardening]

You're very welcome!

[@kathleenrudman9152]

Water strawberries by drip irrigation if possible. Best time for watering, early in the morning, or evening when evaporation is less. For very sweet , large strawberries, feed with plaster of Paris powder.

Helpful information! Thanks for the problem solving aspect; it helps people not kill their plant in the effort to save them from the wrong disease.

I think one magnesium was supposed to manganese and traces of other transition metals are needed to , eg cobalt is required for viable seed production and it is the metal at the centre of vitamin B12 with out it B12 can not be formed just like haemoglobin cant be formed without iron. Silicon is a big one I didnt see on that list , it is not absolutely required but is used in many of the structures of plants

[@ThatGardener]

There is a difference between percentage and ratio but thanks for the vid

[@samgreene7961]

Agreed - the amounts noted are the same as they contain the same amount of ‘active’ ingredients. You wouldn’t use them the same as they contain different amounts.

Taking my first steps to getting a dog. Gotta grow and keep a plant alive for half a year...

[@rosemacaskie]

Its easier to look after a dog, which is more like feeding ourselves. Its really hard to look after plants.

[@thekingoffailure9967]

dogs tend to make more noise before they starve/drown etc but plants dont scream when they become root bound or your window gets too little light

[@tanningasia9982]

ok - great information. But what do we need to do once we identify them? Will be really helpful if you can let us know what we need to add - for instance, calcium can be added through eggshells.

[@Shortcake39553]

This was Amazing and SUPER informative! Wow! I feel like a botanist now😂. Thanks for taking your time to break this down.

would lazy man's compost tea (handful composting scraps in bucket of water, let sit a few weeks, no bubbler) give all the nutrients needed? I also have "cow pond tea" made like lazy compost tea, but using what was found in a cow pond and a kitchen few scraps? so far my plants love it
