By the way looking at that Umostart brochure - what is the relative nutrient load of 5g of Umostart compared to 5g N? Is there the same absolute amount of nutrient in 10kg of Umostart as 50kg of DAP? Or is just more finely ground
It's just finely ground
don't buy into the concept at all personally - just another example of making a cheap product expensive with branding and a bit of very simple processing
