6. Asha went to visit her grandfather in his village. He was having a serious discussion with his fellow members regarding the productivity level of crops for present year. They all were worried about how to increase the productivity of crop Asha listened to this and then suggested to the group that the reason may be decreased level of minerals in soil. She told her grandfather to plant crops like pulses, gram, beans, etc., for a year then follow with regular crops. This will increase the crop productivity (a) What will you name the process suggested by Asha? Why is there decrease in crop productivity? (b) What are noted benefits of this process? Will the results be as what Asha expressed?
Answers
Answer:
a. Crop rotation. There was a decrease in crop productivity as the crops did not receive enough nutrients in order to produce quality products
b. Increase in crop productivity,reduces soil erosion,improves soil structure and limits pests and diseases. Yes the results will be as Asha's expectations
Explanation:
(a) Crop Rotation is a practice of growing crop plants alternatively, here in this case regular crop plants have been rotated with Leguminous plants like pulses, gram and beans.
Generally, a single type of crop growing for long periods on that particular land gradually depletes essential nutrients, Fertilizers though, may be an alternative, yet harmful.
Hence, legumes especially are rotated because of their Nitrogen and phosphorous fixing capabilities. They are good NPK replenishers!
(b) Results are amazing, of course. Since, nature has self potential to heal, a little aid to her in the form of this crop rotation technique would replenish all essential micronutrients and on the top of it this technique is 100% eco-friendly. No pollution and high productivity, the advent of Organic Farming.
