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!

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!

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

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?

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!

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?

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
@sabinacampbell3995 3 жыл бұрын
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.

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.

Is pig slurry considered as containing organic p.k.and n ?
@Swampwild1
@Swampwild1 2 жыл бұрын
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.

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.

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?

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......

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.

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.

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.
