How fertility of soil can be maintained by natural method? Explain this method with an
example.
Answers
Answer:
By employing green manure, cultivating legumes that absorb nitrogen from the air through the process of biological nitrogen fixation, or integrating cover crops that provide organic matter to the soil, which improves soil structure and fosters healthy, fertile soil, soil fertility can be further increased.
Explanation:
To calculate soil fertility, a soil sample is mixed with water, and the N, P, and K are chemically extracted as nitrate, phosphate, and potassium. By contrasting the solution with a color chart, the amount of N, P, and K in the sample is identified. By using methods like crop rotation, conservation tillage, and the addition of compost and manure to the soil, organic or ecological farming aims to foster rich, long-term balanced soil fertility. Synthetic fertilizers and pesticides are also minimized or avoided. Just like people, crops require nutrients. All the essential nutrients for basic plant nutrition, such as nitrogen, phosphorous, and potassium, as well as other nutrients required in lower amounts, will be present in fertile soil (For instance, nickel, molybdenum, boron, copper, zinc, calcium, magnesium, sulfur, iron, and so on.)
