EFFECTS OF AGRICULTURAL BIOCHAR ON HORTICULTURAL SOIL IMPROVEMENT AND CROP GROWTH
ABSTRACT
The results of this study show that agricultural biochar has a very significant effect on soil improvement and crop growth promotion. In terms of soil, the application of biochar can significantly increase soil organic matter content and improve soil structure, so as to improve soil water and fertilizer retention ability. In addition, biochar can also increase soil microbial activity and promote the proliferation and diversity of soil microbial communities. These advantages can provide a good soil foundation for the growth of plants. In terms of plants, the application of biochar can promote the growth of plant roots and the improvement of nutrient absorption capacity, thereby increasing the yield and quality of plants.
