Yep, and you'd be throwing so much money at it with solids that it would be practically uneconomic?I could well believe it, some proper research into the quality improvements are required also that's the most exciting but for me. We've seen a 13% increase in grass ME yield with foliar k (sandy soil so no soil k) and 32% protein yield increase with foliar N and K.
Dairy context is much different ....eg our sweet spot was around 30kgN/ha/year but the trend at that time was to use 80-100kg anyway, basically we were seeing all the good results and less of the bad ones with about 10% of what the district were applying around us, and a lot more profit because of that reduction in direct (and indirect) N costs.
