Now a days due to use of artificial fertilizers in farming, the yield of crop is getting damaged. Soil becomes polluted and unfertilized for crop production. So, we made use of Biochar which is organic material. By using biochar fertility of soil is improved and healthy food is produced for mankind. Biochar has been proven a renewable resource and eco-friendly material for improving soil fertility. The main objective of our study is to increase the water absorbing capacity of soil and to produce crop by organic fertilizer. In this experiment we made comparative study between Biochar and fertilizer (i.e. NPK and organic manure). The time taken by each fertilizer for production of crop (Tomato) and how much water is absorbed by each fertilized soil is compared.
