Statement (i) and (ii) are correct because manure is prepared from the break- down of plant and animal waste products. Hence it is rich in organic matter. Manure contributes to the fertility of the soil by adding organic - matter and some essential nutrients like N, P and K which helps in enhancing growth of plants. Manure makes the clayey soil aerated because of their small - pores and increase the water holding capacity of the sandy soil due to their large pore size. . In clayey soils, the large quantities of organic matter help in drainage and in avoiding water logging. .

Find out the correct sentence about manure(i) Manure contains large qu...
Manure is a valuable organic material that is used as a fertilizer in agriculture. It is obtained from animal excretory waste, such as dung and urine, and it has several benefits for soil health and plant growth. Let's analyze each statement and find out the correct sentence about manure.
(i) Manure contains large quantities of organic matter and small quantities of nutrients.
- This statement is correct. Manure is rich in organic matter, which provides essential nutrients to the soil. However, the nutrient content in manure is relatively lower compared to chemical fertilizers.
(ii) It increases the water holding capacity of sandy soil.
- This statement is correct. Manure improves the water holding capacity of sandy soil by increasing its ability to retain moisture. Sandy soils have larger particles and tend to drain water quickly, but the organic matter in manure helps in retaining water and prevents it from leaching out.
(iii) It helps in draining out of excess of water from clayey soil.
- This statement is incorrect. Manure does not aid in draining out excess water from clayey soil. Clayey soil has small particles that hold water tightly, resulting in poor drainage. Manure can improve the structure of clayey soil by adding organic matter and enhancing its fertility, but it does not help in drainage.
(iv) Its excessive use pollutes the environment because it is made of animal excretory waste.
- This statement is partially correct. Excessive use of manure can lead to environmental pollution, but not because it is made of animal excretory waste. The pollution occurs when manure is applied in excessive amounts, and the nutrients in it leach into water bodies, causing eutrophication. Proper and balanced use of manure can minimize the environmental impact.
Based on the analysis, the correct sentence about manure is option (b) - (i) and (ii). Manure contains large quantities of organic matter and small quantities of nutrients, and it increases the water holding capacity of sandy soil.
