how nutrients replenished in the soil naturally
Answers
Explanation:
The main nutrients required by the plants are nitrogen, phosphorus, and potassium. These are called mineral nutrients or just minerals. The plant nutrients like nitrogen, phosphorus and potassium and present in the soil naturally.
When the plants are grown, they absorb the nutrients from the soil due to which the amount of plant nutrients in the soil goes on decreasing. This reduces soil fertility. And when the crop plants are grown in the same fields again and again, then the soil becomes deficient in the plant nutrients like nitrogen, phosphorus, and potassium.
Answer:
The nutrients replets to the soil in three ways .First is field fallow second is crop rotation and third one is mixed cropping
Explanation:
The soil can regain their nutrients by fallowing the land or free it for one or more seasons.By this the dead plants and animals remains make the soil fertile and regain its all nutrients.crop rotation means rotation of crops in all seasons is called crop rotation it also helps the soil to regaining it's all nutrients.Mixed croping refers to such a way in which different crops are grown in a same piece of land so that the soil not deplete any particular nutrient and by this soil regains it's nutrients.
