for urine patches in clover

Lack of potas­sium in the soil can trans­late into pas­ture pro­duc­tion losses of up to 40 per cent. For­tu­nately, a potas­si­umd­e­fi­ciency is the eas­i­est of all de­fi­cien­cies to spot.

“If I go onto a farm and it’s very patchy, the dung and urine patches are stand­ing out ob­vi­ous, and the pas­ture in be­tween is weedy and the clover is not vig­or­ous, and the clover is vig­or­ous in the dung and urine patches, I can guar­an­tee you that’s a nu­tri­ent de­fi­ciency.

“Potas­sium-de­fi­cient clover has a brown ring around the edge of the leaves, that’s a clas­sic symp­tom.”

Have a look at where your clover is grow­ing, where it’s do­ing best and where it’s not. If it looks green and healthy in urine patches but nowhere else, it’s a big clue that potas­sium is de­fi­cient be­cause urine is very rich in potas­sium.

If clover is grow­ing well in dung patches but not away from it, it’s a clue that ei­ther the phos­pho­rus or sul­phur is de­fi­cient. A sul­phur de­fi­cient clover plant will be very yel­low.
