Question 7
Do you think it is better to use compost instead of chemical fertilizers? Why?


We think that compost is better to use instead of chemical fertilizers. Compost fertilizers are those in which plants and animal extracts etc. are used. These fertilizers usually contain all nutrients in varying proportions. These fertilizers are not made in factories. They are prepared by the farmers themselves using indigenous methods.
They contain a large measure of organic matter. No special precautions are required while using them. In this category includes gobar khad, compost or the mixture made out of organic waste and human excreta, green manure and oil cakes etc.
Chemical fertilizers are manufactured artificially in factories with the use of chemicals. These contain large amounts of plant nutrients. These contain only one and two or three nutritional elements. For examples, Urea, Ammonium Sulphate, Super Phosphate, Potassium Sulphate, Sodium Nitrate, Calcium Sulphate etc.
