(D) Dry

Answer 1

Hint: As we know that manure is organic matter which is used as an organic fertilizer in agriculture and farming. Most manure consists of animal feces while the other sources include compost and green manure. They contribute to the fertility of soil by adding organic matter and nutrients that can be utilized by bacteria, fungi and other organisms present in the soil. So here we have to explain in which condition manure is added to the soil.

Complete answer:
Let us discuss about manure followed by explaining the condition in which it is added to the soil as follows:-
-Manure: It is an organic matter that is used as organic fertilizer in agriculture and also most of the manure consists of animal feces while other sources include compost and green manure. They also contribute to the fertility of soil by adding organic matter and nutrients that can be utilized by bacteria, fungi and other organisms present in the soil. Then the higher organisms feed on the fungi and bacteria in a chain of ecosystem that comprises the soil food web.
-Manure is added to the soil when it is too acidic in pH level.
-It supplies plants with nitrogen, phosphorus, potassium and other nutrients instantly by warming the soil that speeds up decomposition and also lowers the soil's acidity level.
-When the soil absorbs manure, nutrients are released and also its addition to compacted soil helps loosen the soil.

Therefore, manure is added when the soil is too (A) Acidic.

Note:
-Remember that manure produces an increased amount of soil carbon which is an important source of energy that makes nutrients available to plants.
-Other advantages of manure include leaching of nitrates in the soil and reduced runoff.
