The effect of biochar and cowmanure to increase soil fertility in entisol Darussalam
Abstract
The availability of fertil land for agriculture was the main factor to support the cultivation activity. The utilization of dryland in Indonesia did not optimise yet especially in Aceh. The solution to support the utilization of dryland and improve soil fertility especially Entisol that dominated in Aceh through application biochar and cow-manure. The research was conducted in Campus Experimental Site The ACIAR Project from April to October 2017. The randomized complete block design with 2 factors and 3 replications used in the experiment. The first factor was kinds of biochar with some rates (rice husk biochar: 0 t ha-1; 2.5 t ha-1; 5 t ha-1, and cocopeat biochar: 0 t ha-1; 2.5 t ha-1; 5 t ha-1) and the second factor was cow manure with some rates (0 t ha-1; 2.5 t ha-1; 5 t ha-1). The result showed that the kinds of biochar with some rates were effected to soil pH and ratio C:N soil. The used of rice husk biochar 5 t ha-1 was the optimum rate to improved soil pH Entisol.
