INQUIRY BASED LEARNING (IBL)
Use of chemical fertilizers leads to pollution of the environment and a downward trend in soil health. Use of biofertilizers can address this problem and be a mainstay for sustainable agriculture.
Before we can apply biofertilizers we must understand the various factors that affect crop productivity. In addition to selection of hardy crops which give good yield in terms of quality and quantity, we must ensure that the crop gets the right conditions for growth and yield. For this we need to understand various aspects about soil formation, soil types, soil composition, climatic and rainfall/ irrigation requirements and fertilizer requirements of the crops.
