Yer basic nutrient transfer to the extreme.

Crystal Green:

"In the past decade, phosphorus recovery has been the subject of intense research, and there are several new, economical methods by which it can be accomplished, many involving struvite formation. One technique, developed by University of British Columbia professor Don Mavinic, involves a cone-shaped reaction chamber in which small struvite crystals combine with magnesium, ammonium, and the phosphorus in wastewater on its way to a biosolids processor (X). The crystals grow until they are large enough to be collected by a filter and removed. These systems prevent struvite buildup in pipes, prevent phosphorus pollution in water basins, and provide valuable, usable phosphorus fertilizers. A company, Osatra Nutrient Recovery Technologies, Inc., was founded around the technology, and the struvite fertilizer the process creates is marketed as Crystal Green®"

We can/are now buy Crystal Green P recycled fertilizer. 80 years of 'conventional high grade P.
280yrs with lower P grade deposits.

Cheers

"A recent China Agriculture University study found that northern Chinese farmers use about 92 kg of phosphorus fertilizer per acre, of which only 39 kg are removed as crops. This means 53 kg, fully 58% of phosphorus, is not utilized and ultimately lost into the environment (21). As China is the largest phosphorus consumer in the world, with 5.2 Mt consumed in 2009 alone , reducing the country's phosphorus waste by even half would save the world over 1.5 Mt of phosphorus (3.45 Mt phosphate) per year."

Very interesting study by MIT:

Great thread Willy. With phosphorus availability and plant acquisition, that's the primary function of mycorrhizal fungi. Then there's glomalin, the carbon based soil glue it produces. Gabe manages the physical, chemical and biological aspects of soil very well. Farmers are primarily photosynthesis managers. Every cubic metre of air weighs about 1.3 kgs of which 14 grams or so is carbon which will make up the bulk of the plants we grow. Add in too much acid based fert and then imbalance the whole system with pesticides and you're on the treadmill. The Jena experiment in Germany is very interesting. Dr Christine Jones talks about quorum sensing, fascinating stuff.

You should actually try farming full scale , you have some not bad theories on paper .
Ask your friend some opinions that actually farms , I am curious if he reads this site
Does he / she use evil chemicals and herbicide? Do you ridicule him/ her 24/7 ? Looks like a successful farm , how is that possible doing everything wrong ??

Irresponsible post IMO. Why the China bashing? Same phos waste and misuse occurs around the world, especially here in the southern hemisphere. U.S. is no different. Industrial ag to blame

How could it be that Austranada with all the answers ended up working for this farmer who is successfully ignoring all his great advice, and not the other way around.

It is not China bashing when the stats back up the claims that China is grossly over using fertilizer:
Overuse of fertilizers and pesticides in China linked to farm size A new study finds chemicals are often used inefficiently on small farms in China. Land and migration policies may help explain why the country uses 30 percent of the world's fertilizers and pesticides on 9 percent of global cropland

Chinese farmers use an average of 305 kilograms of nitrogen per hectare per year - more than four times the global average.

etc.
And all of that wasted fertilizer is ending up in the environment. And we get over regulated as a result of the damage they are doing.

I get the impression Chinese farmers fertilizer application equipment is not the most accurate or efficient. Heck, this is not limited to China neither.

I could neither afford nor justify applying that much fertilizer that inefficiently on my hilly ground.

A few years ago we imported some polymer coated urea from China similar to ESN. More recently got some ESN through Nutrien. Did some ammonia release rate tests to compare with sulfur coated urea,methylated urea and a couple other products. We found the ESN had the best stable release rate profile enabling higher rates of application with much less loss to leaching or volatilization. Now trying Neem oil coated urea. About 1 litre/tonne. Also slow release effect. Idea originated in India where most urea is neem oil coated because the govt subsidizes N fertilizer to approx 70% so they want efficient use. How's that compare to the rising carbon tax in Can't Nada.

And by sufficiently dense to be economical you mean for the required amount currently used in most mainstream farming practices.

No, poor choice of words on my part.
I was referring to the concentrations of the deposits. Needs to be rich enough that the energy input is justified. Not mining 1000's of tonnes of ore to get one tonne of phosphate. Or millions of cubic meters of sea water.
