Explain how, soil gets affected by the repeated growing of croping the same fields. How does use of fertilizers help the farmers ?
Plants require nutrients for their proper growth and functioning. If continuous plantation of crops is done in the fields then the soil will become poor in necessary nutrients like nitrogen, phosphorus, potassium, etc. This affect the yield and also affects the quality of soil. So, the nutrients once consumed by crop must be replenished so that soil get all its nutrients back and it will be ready for the next harvest.
Fertilizers help the farmers to get better yield of crops such as wheat, paddy and maize.
