Pemberian Bahan Organic Soil Treatment dan Pupuk Kandang Kotoran Ayam Untuk Perubahan Beberapa sifat Fisik Ultisol

Abstract

Research to determine the effect of OST ingredients and manure from chicken manure on the physical properties of Ultisol was carried out with a completely randomized design with factorial patterns. The experimental treatment consisted of giving OST, namely P0 = without OST, P1 = 5 g/pot, P2 = 10 g/pot combined with manure, B0 = without manure, B1 = 40 g/pot and B2 = 80 g/pot repeated 3 times. The results showed that bulk density, porosity, soil pore distribution and aggregate stability were affected by OST material, while manure only affected aerase pores, unavailable pore water and aggregate stability.
