Effect of Sawdust Biochar and Cow Manure Application on Soil Fertility at Peanut (Arachis Hypogaea L.) Land

Abstract

The low available nutrient and C-organic cause dryland has a low fertility rate. Biochar and manure application in agricultural cultivation must be reviewed further in order to obtain an effective and applicable way to increase production yields and to improve soil fertility. The purpose of this study was to determine the effect of sawdust biochar and cow manure on soil fertility in peanut land. This includes two types of soil amendment made from locally available raw materials (sawdust biochar and cow manure). Data analysis was conducted by using Randomized Block Design with factorial 3 x 3 and 3 replications. First factor was sawdust biochar (0 t/ha; 2.5 t/ha; and 5 t/ha). Second factor was cow manure (0 t/ha; 2.5 t/ha; and 5 t/ha). Soil samples were analysis on 45 days after planting and the observed variables were : (1) C Organic; (2) Total N; (3) C/N ratio; and (4) soil pH. The sawdust biochar application has a significant effect on C-Organic and soil pH. The best biochar application was 2.5 t/ha. Cow manure application has not significant effect on C-Organic, Total N, C/N ratio, and soil pH.
