Answer 1

Answer:

2. Ploughing

3. Water

Explanation:

2.The process of loosening and turning the soil is called ploughing (tilling).  Loosening of soil particles adds humus and nutrients in the soil that increases crop yields.

3. Waterlogging occurs whenever the soil is so wet that there is insufficient oxygen in the pore space for plant roots to be able to adequately respire. Other gases detrimental to root growth, such as carbon dioxide and ethylene, also accumulate in the root zone and affect the plants.
