| 概要 |
The experiment was conducted with an aim to know the effect of biochar on soil physico-chemical properties. Two types of soil namely clayey loam and sandy soil and four types of biochars namely, pine ...wood, bermuda grass, rice husk, and bamboo saw dust were used. All biochars were applied at the rate of 5% (w/w). The application of biochar to both soil types increased field capacity, permanent wilting point, and plant available water but decrease the bulk density. Among them, pine wood biochar was best in terms of plant available water (PAW). The PAW was increased by 22% in the clay loam soil. On the other hand, in the sandy soil, the pine wood biochar has pronounced effect to increase PAW by about 37%. Hence, pine wood biochar can be used in the drought-prone areas for both clayey loam as well as sandy soil.続きを見る
