tailieunhanh - Influence of different levels of coconut shell biochar on nutrients concentration and nutrient uptake by soybean

Biochar is a carbon rich substance obtained from thermal decomposition plant biomass through the process of pyrolysis. The special characteristics of the biochar are its effectiveness in retaining most of the nutrients and maintaining them available to plants. The present field experiment was therefore conducted to investigate the effect of biochar application on nutrients concentration and uptake by soybean in acidic soils. Biochar produced from coconut shell was applied at the rates of 5, and 10 t ha-1with two rates of recommended lime (100 and 50%). |
