Abstract

The application of rice huskbiochar enriched with farm yard manure (cattle dung) as ameliorant to soils have shown benefits for production such as maize (Zea mays), shallot (Allium cepa), and peanut (Arachis hypogea),  particularly through improving soil properties  and crop productivity.  However, studies examining the effects of enriched rice husk biochar on farms in upper land area of Karawang District not yet reported. This paper presents the results of research focused on the use of enriched rice husk biochar (enriched cattle dung manure) and rice husk only at the rate of 5ton.ha^-1 and 10ton.ha^-1, in farmer fields as a soil amendment on upper hill silty-clay loam texture of Typic Hapludults in Karawang District. The study indicated that there were significant (P<0.05) positive effects in  a certain silt-loam soil properties like soil pH, SOM and nutrient status, and crop production. Results of this study suggest that the practice of rice husk biochar application to soil at low rates must be enriched along with rice husk normally has immediate positive effects on the vegetative growth of crops, however, soil properties and overall crop yields may take a longer time to show improvement.
