Detailed explanation-1: -Lime improves soil structure. When lime is added to clay soil, the tiny clay particles group themselves around the lime particles and together form larger particles. The process is called flocculation because it reminded someone of a flock of sheep coming together.

Detailed explanation-2: -One way of improving the texture of a clay soil is to add lime. This raises the pH of acid clay soils, making them more alkaline and in doing so it encourages clay particles to stick together in small clumps. This results in larger particles and makes the soil more friable and easier to work.

Detailed explanation-3: -Lime is a soil conditioner and controls the soil acidity by neutralising the effects of acids from nitrogen (N) fertiliser, slurry and high rainfall. Other benefits include an increase in earthworm activity, improvement in soil structure and grass is more palatable to livestock.

Detailed explanation-4: -Agricultural lime helps lower the soil’s acidity levels by rendering it more pH neutral. By applying lime to the soil when it becomes too acidic, farmers can ensure they are helping improve their crop output. If crops can’t properly grow, they can’t produce, which impacts the agriculture business and its bottom line.

Detailed explanation-5: -flocculation is the act by which lime is being added to clay soil, inorder to improve the nutrient present in the soil, the correct option is B, flocculation is the right answer.
