THE INFLUENCE OF URIN FERTILIZER, BOKASHI LEAF, AB MIX FOR KANGKUNG PLANT GROWTH (Ipomoea reptans var.Poir) WITH THE SYSTEM HYDROPONIC DFT (Deep Flow Technique) IN INDONESIA ADVENT UNIVERSITY

Urine cow is livestock waste that can be used as liquid fertilizer. Urine has a high N and K and there is enough P content for plant development. Besides being able to work quickly, urine turns out of contain certain hormones that can stimulate plant development. Urine in catle consist of 92% water, nitrogen 1.00%, 0.2% phosphorus, and 0.35% potassium.
