These laboratories have total analysis capacity of 25000 sample of leaves. Such new laboratory is being set up at Saloh in Una district. Besides providing facilities of analysing micro contents like iron, manganese, copper and zinc major nutrition contents like nitrogen, phasphorus, potash, calcium and magnesium are being provided in the laboratories.
