We're dryland farming in West Gippsland. Roughly our NPKS figures are
302:15:30:8
We soil test regularly to monitor levels, and pretty much the only PKS goes
on crops, and the levels haven't changed. I think a lot of people
underestimate just how much fertiliser is brought on farm via feeds. And by
strategically applying wastes (solid and liquid) you can 'even out'
fertility on your farm. We do consider applying S in the form of gypsum,
which is also a soil conditioner.
Being a bit cheeky, I'd recommend anyone applying fertiliser should soil
test, and throw away the fertiliser recommendations that come back with the
result!
