Answer:
ans1- Human life mainly depends on agriculture for fiber, biofuel, drugs and other products used to sustain and enhance human life. Solution: Agriculture, also called as farming or husbandry, is the cultivation of animals, plants, fungi, and other life forms. Civilization began with agriculture. From employment generation to contribution to National Income, agriculture is important.
ans2- 1. penetrating the land. 2. Levelling. 3. sowing 4.irrigation.5.sprinkling pesticides. 6.harvesting.
ans3- Advantages of ploughing the soil are: - Tilling of soil helps in loosening and turning off the soil, the nutrient-rich soil is distributed evenly and also it improves aeration. - Ploughing helps to improve the water retention ability of soil in the form of capillary water.
ans4- Seeds should be sown at proper depth.
Seeds have to be sown at correct distance.
Soil should be fertile. This conversation is already closed by Expert.
ans5- Natural methods by which lost nutrients are replenished in the soil are:
1. Adding cow dung and manure to the soil.
2. Bio compost can be added to the soil
3. Vermicomposting can be used as earthworms naturally help in maintaining soil fertility by aeration of soils.
4. Growing leguminous plants which contain bacteria Rhizobium that fixes atmospheric N2.
5. Growing other N2 fixing bacteria.
6. Crop rotation.
7. Watering the soil at proper timing and
8. Planting deep rooted plants around the field which help to retain water content of the soil.
ans6- Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation.
ans7- The main classes of crop protection chemicals are herbicides, insecticides and fungicides. Selective herbicides, for example, control the growth of weeds which would otherwise grow among a crop, competing with it for water, nutrients and sunlight. Without crop protection chemicals agriculture would be less efficient.
