Fertiliser

By Scutter
Artificial fertiliser is applied to almost all crops that are not grown organically in the UK. This is a blend containing nitrogen, magnesium and sulphur that is being applied to a crop of winter wheat. Since the Clean Air Act of 1956 the amount of atmospheric sulphur deposited on crops in the UK has declined. So much so that sulphur now needs to be applied to crops (particularly oilseed rape but also cereals grown on lighter soils i.e. chalky or sandy soils).

Fertiliser increases yield dramatically. Without nitrogen a crop of wheat would typically yield 4 t/ha with adequate fertiliser it will yield between 9-12 t/ha (other factors such as adequate rainfall and disease control also affect yield).

This is a shot of the fertiliser in the spreader mounted on the back of a tractor. I liked the abstract nature of this shot which I will be using in presentations etc. that I give to farmers in the course of my work. I am sure it will mystify most of you on here but never mind you might learn something from reading thisSmile

I really like your composition here, and it's criminal this hasn't even garnered a single vote. Consider that rectified.

Thanks Michael, I don't mind the lack of votes. It is a bit specialist. I have used in my work life quite effectively!!
