Choose the correct statement related to manure in farms :
(i) These have more organic matters and less nutritional elements
(ii) They increase the water holding capacity of sandy soil
(iii) They help to extract the extra quantity of water from loamy soil
(iv) They pollute the environment, because it is made up of the excreted waste of animals.

Options

A. (i), (ii) and (iii)
B. (ii), (iii) and (iv)
C. (i), (ii) and (iv)
D. (i) and (ii)

Explanation

To solve the question regarding the correct statements related to manure in farms, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement (i): These have more organic matters and less nutritional elements.**
- Manure is primarily composed of organic matter derived from the decomposition of animal waste and plant materials. While it does contain some nutrients, the organic matter content is generally higher compared to the concentration of specific nutritional elements.
- **Conclusion:** This statement is **correct**.

2. **Statement (ii): They increase the water holding capacity of sandy soil.**
- Sandy soil has larger particles and tends to drain quickly, leading to lower water retention. When manure is added, it introduces organic matter (humus) which can fill the spaces between the larger sand particles, thereby increasing the soil's ability to retain water.
- **Conclusion:** This statement is **correct**.

3. **Statement (iii): They help to extract the extra quantity of water from loamy soil.**
- Loamy soil is a balanced mixture of sand, silt, and clay, which already has good water retention properties. Manure does not extract water; rather, it helps improve water retention. Therefore, this statement is misleading.
- **Conclusion:** This statement is **incorrect**.

4. **Statement (iv): They pollute the environment, because it is made up of the excreted waste of animals.**
- While manure is made from animal waste, it is organic and biodegradable. When properly managed, it does not lead to pollution; instead, it can enhance soil quality. Thus, this statement is also misleading.
- **Conclusion:** This statement is **incorrect**.

### Final Conclusion:
The correct statements related to manure in farms are **(i)** and **(ii)**. Therefore, the answer is option **1 and 2** are correct.
