ADAPTABILITY OF THE TECHNOLOGY

This techology is best suited to small-scale farming, and to sandy, acidic and relatively infertile soils. It is effective for such crops as soybean, cowpea, corn and sorghum. It is also worth trying for other field crops and vegetables. Fig. 1 Tin can with ventilation holes and chimney

HOW TO PREPARE THE CHARCOAL
Prepare the rice husk charcoal as follows.

On highly weathered soils in tropical and subtropical climates, maintenance of soil organic matter is essential to sustain system productivity and avoid rapid soil degradation. But climatic conditions as well as soil characteristics favor the rapid decomposition of organic matter. However, several recent studies indicated that black carbon, the product of incomplete combustion of organic material, could combine characteristics highly beneficial for soil nutrient dynamics with high stability against chemical and microbial breakdown. Lasting soil amelioration by incorporation of black carbon from wooden plants was proposed based on the beneficial evidence from
