Answers
Answer: 1. The nitrogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms
2. Manure is an organic substance that is obtained from decomposition of vegetables and animal waste. Fertilizers are inorganic substances manufactured in factories. Manures are relatively less rich in plant nutrients, they only remove general deficiency of soil.
3. compost is done in a pit in which the dry leaves , vegetables etc . are put into a pit with a hole at down of the pit. after that it is covered with soil and we will leave it for many months . After that the compost will get ready which makes the soil fertile.
4. Harvesting is the process of gathering a ripe crop from the fields. Reaping is the cutting of grain or pulse for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season

6. Why Is Crop Rotation Important? Crop rotation helps to maintain soil structure and nutrient levels and to prevent soilborne pests from getting a foothold in the garden. When a single crop is planted in the same place every year, the soil structure slowly deteriorates as the same nutrients are used time and time again.
7. Mixed cropping is a system of sowing two or three crops together on the same land, one being the main crop and the others the subsidiaries
