| Abstract | ||||
| The use of biochar as soil conditioner, either alone or in association with fertilizer, may be considered a specific management for improving the soil properties which adverse crops productivity. A field experiment was carried out in a sandy soil, winter season cultivated with lupine and summer season cultivated with peanut, to study the effectiveness of applying particle size of biochar at different depths to improve soil properties, nutritional status and yield components of crops. The experiment included four particle sizes of biochar S1, S2, S3and S4 and three application depths D1, D2 and D3. Results indicated that, generally, the application of biochar particle sizes with different application depths led to increase lupine and peanut yields as well as their total content of macronutrients as compared to control treatment. Also, application of 10 mm biochar at D2 and 2mm bichar at D1 were significantly superior for lupine and peanut yields along with their total content of macronutrients, respectively. Data showed that the application of S1biochar and S4 biochar were superior decreased of pH values in the first and second seasons, respectively. The electric conductivity and organic matter were increased gradually with increase of biochar particle sizes in lupine soil, while these parameters in peanut soil being decreased. In conclusion, application of biochar, with different sizes and depths, as soil conditioners led to improve soil chemical properties and increased fertility in sandy soil which reflected on both tested yield components along with their total content of macronutrients under conditions of experiment. | ||||
