Study the Effects of Rice Husk on Geochemical Properties of Soil and Its Growth Promotions

The fertility of the soil is decreasing day by day. Because of that, the crop yield has decreased. To improve soil fertility more fertilizers are required. But the chemical fertilizers are costly and also harmful to the environment. So that an alternate way for chemical fertilizers are to be identified. Our study is focused on the improvement of soil fertility with the help of rice husk and Bacillus spp. The soil samples were collected and tested in the laboratory to find out the soil fertility. Two different seeds (Fenugreek, Greengram) were taken to analyze the soil fertility. The three different types of samples like tap water, treated water, and controlled water were used. The analysis of plant growth was carried out with application of the three samples. The plant growth in terms of no. of leaves; stem size and root length is analyzed. The estimation of carbohydrate, protein, and chlorophyll content of the plant samples were discussed in this study. In this study we use growth assay, height assay techniques to find out the plant growth. And also various tests like carbohydrate test, protein test, and chlorophyll tests are conducted to find out plant nutrition content in order to find out the soil fertility level. The result was interpreted with the help of graphs. Our study has revealed that application of rice husk in soil can alter plant growth and nutrition. Compared to the normal tap water our control, treated sample shows better shoot, root length. The carbohydrate, protein, and chlorophyll values of the control, treated sample show better results.
