Rotating crops with legumes or grass pastures to improve soil fertility is referred to as lay farming.
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.
The correct option is (D): Ley farming.
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:
So, the correct option is (D): Ley farming.

A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
