Abstract
The Heap of sugar palm solid waste often become pollutants, potentially used as organic fertilizer by making it compost, because it contains organic matter and high N. Regosol is soil that has poor physical and chemical soil conditions for corn growth because it is constrained by sand dominated soil texture and low N. This study aims to determine the effect of compost from sugar palm solid waste on the availability of N Regosol and its uptake by corn. This research is a pot experiment, using Complete Random Design method (CRD) with 5 treatments, each treatment was replicated 3 times. The five treatments are: K0 = Compost at a rate of 0 tons / ha (control), K1 = Compost at a rate of 22.24 tons / ha, K2 = Compost at a rate of 44.48 tons / ha, K3 = Compost at a rate of 66.72 tons / ha and K4 = compost at a rate of 88.96 tons / ha. The results showed that the application of palm sugar solid waste compost could increase the Nitrogen availability of Regosol and Nitrogen uptake of corn. Application of palm sugar solid waste compost at a rate equivalent to 44.48 tons/ha significantly responds to the increased availability of Nitrogen Regosol and the best Nitrogen uptake of corn.
