Why farmers should do interchanging crops ?
this is for 3 marks answer in brief
Answers
Alternating between crops with different root systems also offers benefits. Plants with longer roots can get nutrients from deeper layers of the soil than those with a shorter root system. When you alternate between crops like this, you keep the soil healthy.
Answer:
THERE ARE THREE REASONS WHY SHOULD FARMERS INTERCHANGE CROPS THEY ARE :-
i)If you don't rotate crops, the soil in that field will inevitably begin to lose the nutrients plants need to grow. You can avoid this by sowing crops that increase organic matter and nitrogen in the soil.
ii) When planning crop rotation, keep in mind the residual effects of the herbicides you used to treat previous crops. For example, the residual effect of sulfonylurea herbicides can adversely affect sugar beets, while triazine herbicides may negatively impact alfalfa seedlings.
iii) If you alternate crops correctly, control crop conditions, and maintain soil fertility, you boost your chances of having a good harvest.
