Provision of Urea Fertilizer and Chicken Manure on Chemical Characteristics of Inceptisol Soil in Pangkatan District

Inceptisol soil is an agricultural land in Indonesia, which widely distributed, but has a problem, namely the element of N relatively low, so it necessary to carry out proper cultivation techniques, one through provision balanced fertilizers, organic fertilizers aim improve fertility and reduce use NPK fertilizer. This study aims determine effect various kinds sometimes goat urea fertilizer on chemical properties Inceptisols from Pangkatan. research was conducted Agrotechnology Practice Area, Faculty Science Technology, Labuhanbatu University, Rantau Prapat, with height 25 meters above sea surface. The started February 2021 June 2021. used factorial randomized block design (RBD) 2 treatment factors. namely: Urea factor four levels manure three levels. Soil analysis parameters include, pH H2O using electrometric method, determination N-total Kjehldal C Wakley Black method. results showed that application able increase N-toatal Pangkatan, at dose U1K3 (Urea: 0.25g manure: 75g) while interaction increased Inceptisol. South 75g).
