Which crop is generally sown to restore and maintain soil fertility?

Question 17 Leguminous crops like pulses and beans are generally grown between two kinds of cereal crops in crop rotation to restore the fertility of the soil.

What crops help make the soil fertile again?

Some cover crops directly add nutrients to the soil by fixing nitrogen at their roots. Examples include winter field beans and peas, clover and vetch. These are all types of legume and are a great choice for sowing before nitrogen-hungry brassicas such as cabbage.

What is required to maintain the fertility of soil?

Crops need nutrients just like people do. A fertile soil will contain all the major nutrients for basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities (e.g., calcium, magnesium, sulfur, iron, zinc, copper, boron, molybdenum, nickel).

Which one of the following is suitable for restoring soil fertility?

For restoring soil fertility the suitable among them is rotation of crops.

Which of the following crop can be grown to restore the fertility of soil by fixing nitrogen from air?

Legume crops such as beans, peanuts and soy can fix nitrogen from the air, and flourish on nitrogen- deficient soils. To do so, they need help from Rhizobium bacteria. These special bacteria stimulate the growth of nodules on the roots of leguminous plants.

How can soil fertility be restored?

Some organic farming techniques that help restore the soil include use of green manure (uprooted or sown crop parts incorporated or left on topsoil), cover crops, crop rotation and organic compost.

What are the natural methods to restore soil fertility?

The natural methods to restore soil fertility are as follows:

• Organic Fertilizer: => It includes animal manure, crop residues, bone meal and composite, becomes available to plants and only as they decompose.
• Animal Manure:
• Green Manure:
• Compost:
• Crop Rotation:

What is soil fertility in agriculture?

Soil fertility is the ability of a soil to sustain plant growth by providing essential plant nutrients and favorable chemical, physical, and biological characteristics as a habitat for plant growth.

Which of the following pulses does not help in restoring soil fertility?

Most species of pulses are such plants except the Tur (arhar) dal. So, while pulses are grown in rotation, Tur dal is not, since it does not help the soil fertility.

How nitrogen is restored in soil?

One way that nitrogen is released into the soil is through the decomposition of organic matter. Another is the process of nitrogen fixation. In this process, specialized microbes colonize the roots of certain plants — mainly from the legume, or bean, family — and convert atmospheric nitrogen into a soluble form.

What are some organic farming techniques to restore the soil?

Some organic farming techniques that help restore the soil include use of green manure (uprooted or sown crop parts incorporated or left on topsoil), cover crops, crop rotation and organic compost. • Green manure and cover crops: Green manures and cover crops serve as mulch to the soil preventing the soil from wind/water erosion and moisture loss.

Which crop can be used to improve the soil?

Any crop can be used to improve the soil, provided that you till it back in at the end of the season. Perhaps rice farmers till in the rice straw, for example.

What are the benefits of green manure?

• Green manure and cover crops: Green manures and cover crops serve as mulch to the soil preventing the soil from wind/water erosion and moisture loss. They also increase the soil organic matter content as they decompose in the soil. Green manure and cover crops that are legumes (plants which produce seeds in pods) have nitrogen fixing ability.

Which of the following is heavily consumed by fast growing crops?

Soil nitrogren is heavily consumed by fast growing crops. Lawns, for example, grow fast and green with 30-0-0 (heavy Nitrogen) fertilizers. In general all crops need a source of nitrogen, whether it is from the soil or from an applied fertilizer.
