Top - Phos

[fjlip]

TOP-PHOS IS A SCIENTIFIC AND INDUSTRIAL REVOLUTION

• New manufacturing process – unique chemical signature
• New complexed raw material
• EU Reach registered
• Ag In Motion 2019 Innovation Award winner
• Provides soluble phosphates in high and low pH soils
• 100% Orthophosphate

KEY BENEFITS
• Complexing agents protect phosphate against tie up in low and high pH soils
• Water-soluble phosphate
• Root biostimulant effect
• Low salt index (9)


Anyone have experience with this ?

Need to put more than they recommend.
Based on my own small trials

The grain business has been too good for too long. There is an amazing array of snake oil being offered to farmers and apparently at least some of you are buying.

Do you buy semi loads or a few jugs in the back of the pickup?

Hauled with the Datsun. Lmao!

This idea that phosphorus in its traditional fertilizer formations is becoming “locked up”. I’d like to see the evidence for this. I’m talking long term inaccessible loss to the point that a producer would not be able to utilize this phosphate for plant growth in the foreseeable future.

I like the low salt feature of some of these new products and perhaps we have a good candidate for a seed safe starter but I doubt this has any economical value as a soil nutrient building tool.

It’s a better product but you have to
Use more than they say. Root growth
Much higher crop greener and healthier
But in the end not a whole lot of yield benefit
at these prices it pays
But at the old prices it s debatable. This was
However under poor moisture conditions
Maybe in better moisture the difference would
Have been more maybe not.

At the risk of being called a whack or used snakeoil kook, have any of you guys looked into or have any experience with Thermo Poly Aspartate (tpa) for using to impregnate dry phos (map,dap)?

It's a negatively charged synthetic bio polymer. Essentially has a hi cation exchange capacity that minimizes bonding between + charged ions. for example hi ph calcareous soils are high in Ca2+ likewise lo ph acidic soils are high in fe3+ and al3+. The negatively charged protein has a weak covalent bond when impregnated with po4- thus not allowing it to react with other metal ions in the soils reducing tie up and utilizing what's actually applied verses the % loss to bonding with other metal ions.

Very interesting and relevant topic.
Question, does anyone on here have a degree in chemistry?

So tpa is a chelation product. No never heard of it.

Humic acids are accepted in the green houses, jurry still out still a chelation product

The other chelation products such as edta might have environmental - safety issues ( this is what many currently available - commercial products use
