Question

A system of rotating crops with legume or grass pasture to improve soil structure and fertility is called :

• A. Contour farming
• B. Strip farming
• C. Shifting agriculture
• D. Ley farming

Answer 1

The Correct Option is D

Lay Farming Explanation 

Rotating crops with legumes or grass pastures to improve soil fertility is referred to as lay farming.

Explanation:

In lay farming, certain crops, especially legumes or grass pastures, are alternated with other crops. This practice helps in replenishing the soil with nitrogen and other essential nutrients, ultimately improving its fertility. Legumes, for example, can fix nitrogen in the soil, reducing the need for chemical fertilizers.

Conclusion:

The correct option is (D): Ley farming.

Answer 2

Explanation:
Ley farming is a technique used to improve and preserve soil fertility while providing livestock with all the grasses and legumes they need for pasture, silage, and hay that they need in a correct rotation. Leys are pastures that are sown for two to five years and consist of grasses and legumes. They are employed in a series of ploughs for grazing, and the field is ploughed once more after a predetermined amount of time.
Ley farming has many advantages like:

• Ley farming improves the nitrogen content of subsequent plants.
• Grain quality, crop productivity, and soil fertility are all increased by legumes.
• Preservation of organic materials and soil structure
• Reducing deep drainage and erosion
• Boosting livestock productivity

So, the correct option is (D): Ley farming.
