I've been thinking for a while we need to up rates for modern varieties. Yields are pretty stagnant but it's maybe because we still use old N rates from long ago. Was saying to dad the other day , roughly , if 80units (old skool for his benefit) can grow 2 ton an acre , then surely we need 120units for 3 with same N dilution
It's just having the bottle to actually try it with malting barley
I’m using 150 kg/ha N for 1.85 Planet and Laureate on light land after wheat with low soil N. Your post harvest grain N levels will tell you whether you’ve got the right dose or not. Hard to gauge in advance or when you’re getting unusually high or low yields.
