PENENTUAN KANDUNGAN UNSUR HARA MIKRO (Zn, Cu, DAN Pb) DIDALAM KOMPOS YANG DIBUAT DARI SAMPAH TANAMAN PEKARANGAN DAN APLIKASINYA PADA TANAMAN TOMAT (Solanum lycopersicum Mill)

Abstract: The content of micro nutrients (Zn, Cu, dan Pb) in compost made from yard plant waste and it’s aplication tomato plants (Solanum lycopersicum Mill) has been determined. The aim of composting is to replace inorganic fertilizer on agricutural land especially in tomato plants and to investigate a good dose’s in composting tomato plants. To study the influence of dose’s, ANOVA 2 variable with repeat assay has been applied. Micro nutrients (Zn, Cu, and Pb) available in plant growth were measured by Atomic Absorption Spectrophotometric (AAS). The compost media mixed well in soil with composition of compost (6 Kg : 1 Kg) and Zn; Cu, Pb were 1448,14; 155,39; and 353,35 mg/Kg, respectively. While for media inorganic fertilizer it was found to be: inorganic fertilizer (6 Kg : 0,01 Kg); and Zn, Cu, and Pb were 1553,19; 171,72; 340,31 mg/Kg, rspectvely.
