Dr. Christine Jones"The Phosphorus Paradox"

[@rickcameron4507]

Thankfully, This significant explanation by Dr Jones is very helpful why our 100 sq meters monitor lot of 250 kgs ha superphosphate annual dressing for 10 years compared to nil treatment other than sheep grazing has 46% less water holding capability. In August NZ time at 300 psi resistance the probe went down 22 inches for nil grazed, 15 inches superphosphate grazed, 8 inches on a to land stewards's plowed grazed and 2 inches on a high urea site grazed. The grass mass was similar on all 4 . If the carbon sponge is an earth cooling solution for the 94% water vapor, the significance to push beyond the political CO2 and methane arguments is huge for land managers. Thank you Dr Jones!

Super helpful webinar. Thank you Dr. Jones and Green Cover for doing this.

[@mrinalpatra3980]

Thank you green cover for posting such an informative webinar. I have also watched few other related webinars and they are all very helpful in developing comprehensive understanding on the subject of plant nutrition. Now I need to put these into practice.

[@marvinbaier3627]

You all have awesome webinars. I really enjoy all the videos.

No need to mine phosphorous. No worry about peak phosphorous. it's all about building healthy soil. It's that simple. It's paradox that conventional farmers spend tons of money on NPK and up to 90% is wasted and pollutes the soil and water. That's like throwing money away!

[@alisterstewart4783]

It literally is throwing money away. Take nitrogen for example. 78% of the air is nitrogen meaning there's like 48000 metric tons above every 2.5 acres (1ha) but if you don't cover the soil you can't get any free nitrogen as the azotobacter need moisture to move as they can only swim and they want plant material to eat.. building healthy soil has NPKS and a bunch of other things in it. You can do it for free

[@strartur]

​@@alisterstewart4783 It's a primitive statement. Comparable to saying that almost ¾ of the earth is covered by water but the farmers are throwing away money and resources for irrigation of land. Ever tried to grow crops without conventional fertilizers and make money out of it and feed and educate a family of 4? Outside a pet project farm inherited, among other wealth, from 5 generations before you?

The difference between surviving and thriving depends on the microbiome. I have been learning more about what constitutes healthy soil in my biochar study/teaching.

[@davideforesti7556]

Very nice! That kind of soil disturbance can be achieved with animals instead of machinery, without compromising soil function and feeding them, instead of buying fuel.

[@lwhowell4387]

My mind is spinning somewhat. Cover crops resonate with me however I'm also intrigued by the "Back To Eden" paradigm of laying wood chips in between crop rows (vegetable garden) with the premise of weed suppression and water retention. Can you offer your thoughts/experience with this?

[@lwhowell4387]

Thank you!

[@tesetreiiic45324]

I am trying to find scientific paper behind Phosphorus Paradox, specifically claim "adding water soluble phosphorus inhibit soil building process", since my agronomists require some scientific proof about this. I am not managing to find one, but I think this is really important.

[@GreenCoverSeed]

Search Google Scholar for articles about phosphorus availability through biological or mycorrhizal associations... there are quite a few papers listed there

[@scottsmith7973]

I am also interested in seeing evidence of this. I spent some time reviewing Google Scholar as indicated above but was not able to find a study that addressed this question.

[@jesseknox9322]

I'm a dumb country boy trying to retain all this, but it's incredible! What about the relationship with zinc? If your 10:1 ratio is out of whack should I add zinc or let the cover crops handle it?

[@Swampwild1]

Manitoba Canada is a hog factory hot bed. We are currently expanding the industry rapidly. Our Technical Review Committee uses 60 ppm phosphorus as acceptable. So a 1200 hog factory spreads on a few hundred acres legally. This while Lake Winnipeg is dying from algae blooms!

[@cynthiaquilici6793]

You said that soil tests were done at the end of summer, with recommendations for future applications being based on levels that are low at that time. When, generally speaking, is phosphate then applied subsequent to the tests? If application tends to be consistently timed, would that have an effect on the numbers displayed?

[@timthaler6363]

Dr. Christine Jones’ talk "The Phosphorus Paradox" addresses the common misconception that agricultural soils need continuous phosphorus inputs to support plant growth. She explains that many soils already have significant phosphorus reserves, often enough for over a century, but much of it is bound in forms that plants can't easily absorb. Jones argues that instead of applying more phosphorus, improving soil health through organic matter and soil biology can make existing phosphorus more accessible. This process relies heavily on beneficial microbes like mycorrhizal fungi, which help release phosphorus by interacting with plant roots. The “paradox” lies in how excessive, synthetic phosphorus applications can create dependency and reduce soil biology’s role in mobilizing this nutrient, potentially leading to pollution through runoff into waterways. Jones promotes sustainable practices, such as cover cropping and reducing synthetic inputs, to enhance natural phosphorus availability, benefiting both agriculture and the environment​.

Is pig slurry considered as containing organic p.k.and n ?

[@Swampwild1]

Pig slurry may be organic because it’s not made artificially, but it’s anaerobic and highest in phosphorus of all manure. The industrial hog barns which are always used produce the worst manure for the environment. In NA we have the lowest standards in the world.

Lots of liquid manure from a mega dairy in my neighborhood and can't imagine it ever being economical to compost all of it. What would happen to the production level of a row crop field if one went 10-20-30- + years without ever applying phosphorus? Wouldn't it just be easier and less risk to spend $10-15 per acre per year on a little MAP (11-52-0) (50 lbs per acre) every year as opposed to going through the trouble of something like this?

[@sabinacampbell3995]

Presumably the mega dairy already shovels the manure which lands on concrete into a pile. By all means stick with the 'more on/moron' principle and see what serves you. If you don't include plant diversity, you won't get the improvements described so you can't pick one thing out of the 'fruit salad' and expect to get all the flavours.

[@tesha199]

You clearly didn't get the point of this video, which is that adding any extra soluble fertiliser will only keep degrading the soil

[@gemadepatriciocasas1611]

We need more scientists like dr Jones that recognised when science have been wrong (working with dead soil in lab experiments).

[@biondanishgenomeinstitute8193]

Isn't the epigenome, the DNA-based mechanism by which signals in the environment influence gene expression in plants and all other higher life, one more whole dimension in this picture?

[@theexterminator1]

If you have a p deficiency in a 5 gallon pot you have to add p. Even if you test the soil before potting it won't detect the p soooo. So alternating soluble npk and say great white or recharge is useless? Then why does the "recharge" show a visible pop in growth. I know this is a year old but......

[@josephuicker3872]

I wonder how root exudates can attract microbiology in the soil, to the roots. Ants are known to harvest the honeydew from aphids. I suspect that ants or other arthropods or earthworms are harvesting root exudates. These arthropods carry the beneficial bacteria to the roots in their holobionts.

What about doing healthy soils for orchards? Where I live the dirt in the orchards looks terrible dead with only weeds growing. Many keep telling me to not grow grasses or cover because it will take away from the roots of the trees but they then want to put on fertilizers and other feeding chemicals but gotta keep those weeds away from the trees so they don’t suck up the nutrients. Which as Ive said there are no nutrients. Im trying to convince my wife to do the cover between the trees to make the soil healthy again and to allow the trees access to the abundant new source of food. We do organic but we did continue to till including around the trees as we were taught to do so the water would get down to the roots. Im not so sure anymore but I only hear of people using this technique in open fields and ranches and not in the orchards.

[@charlesdevier8203]

We have a small home garden/orchard with 40+ fruit trees, all less than 5 years old. We allow the mixture of grass, white clover and Korean Lespedezia to grow all over, even under the trees. We do keep it mowed to 3-4 inches in height, much like in Dr. Jones's picture with a cover crop of White clover and corn. We will never use "Roundup" in the orchard.

This information if accepted will destroy the hog industry. Or I should say require it to act responsibly. All barns are based on slurry spreading rules. The economic model depends on easily applied manure.

For example: Dr Jones says that obviously manure applied to the soil that’s not needed will wash into the water. Here in Manitoba our 2 billion dollar a year industry is based on the soil experts saying (Dr Don Flatten) zero leaches when injected. How can opinions be so divided?

[@jimlewis1992]

Raw manure is right full of salt. Like just as bad as synthetic fertilizers. Needs to be composted first. Manure from a pen is fine, she is referring to liquid raw manure from dairy cows or hogs.

@@jimlewis1992 most synthetic fertilizer is astronomically higher in salt then any type of manure not even close
