What are thoughts for K use this season. We have generally good levels, mostly in the moderate range, some high and some in the low category.
With the price of MOP at the moment I am toying with not putting any on cereals this year and saving what was earmarked for that for next year on carrots and potatoes that are obviously more responsive to K applications. This MOP is valued at an average of maybe £400/t. And the tonnage I have in stock would be enough to cover 90% of next years root crops.
Could I substitute some of the omitted K with a bit of foliar (and if so what product and at what timing?) maybe applied 2 or 3 times with fungicides instead, but I don't want to impact yield.
This is obviously not a long term sustainable plan, we use all the straw on the farm for covering carrots so we keep as much K here as possible and we get as much chicken litter as we can but do still need to top up with K.
Any opinions welcome.
