Answers
Explanation:
Answer :
Plants require nutrients for their growth. Continuous plantation of crops results in depletion of certain nutrients like nitrogen, phosphorus, potassium. This results in the decrease of yield.
Nitrogen :
It is found in healthy soils, and give plants the energy to grow, and produce fruit or vegetables. Nitrogen is part of the chlorophyll molecule, which gives plants their green color and is involved in creating food for the plant through photosynthesis.
Phosphorus :
It is a constituent of plant cells, which is essential for cell division and development of the growing tip of the plant.
Potassium :
It is an essential element for plant growth and it is important to food crops. Potassium, often called potash, helps the plants to use water and resist drought conditions. It also enhances fruits and vegetables. If soluble potassium is deficient in soil it can result in stunt growth of plants and can also cause other symptomatic issues.
Thus deficiency of any of the nutrient can affect the crop adversely and hence to let the soil replenish its nutrition naturally there should be a gap between crops in order to get a good yield.
Answer:
If wheat is sown in the Kharif season (from June to October), then the whole crop might get destroyed because of many factors such as lack of optimum temperature, adaptability, availability of pests, etc. Kharif season includes the rainy season, which is not favourable for the growth of wheat crop.

Continuous plantation of crops makes the soil poorer in certain nutrients as the crops take up nutrients from the soil. The soil becomes infertile.
