13. the following are importance's of soil except!
14. which crops grow well on clay soil
15. Plants that needs little amount of water while growing up do best in which type of soil
16. Three of the following animals lives in the soil except one. which one is it?
17. the following are some of the components of compost manure except?
18. the site of the compost manure should be
19. how long should the compost be left before its ready for use
20. why is water sprinkled in a compost manure
21. the following are importances of compost manure except?
22. What is the main reason why it is important to conserve our soil?
Soil is essential for growing crops which provide food for humans and animals.
23. What can happen if soil is not conserved properly?
Improper soil conservation can lead to soil erosion, loss of fertility, and reduced crop yields.
24. What is one way to conserve soil on a farm?
Using cover crops can help protect the soil from erosion, help retain moisture, and improve soil fertility.
25. How does deforestation affect the soil?
Deforestation can lead to soil erosion as tree roots help hold the soil in place, and nutrient depletion as organic matter from trees is removed.
26. What can help prevent soil erosion on a slope?
Terracing and planting on contours can help reduce the speed of water flow, prevent erosion, and improve water infiltration into the soil.
27. What can farmers do to improve soil fertility naturally?
Crop rotation and intercropping can help maintain soil fertility by preventing the depletion of specific nutrients and promoting natural pest control.
28. How does improper use of pesticides affect the environment?
Improper use of pesticides can harm beneficial insects like bees and ladybugs, which are essential for pollination and natural pest control.
29. Which of the following practices is NOT environmentally friendly?
Excessive use of synthetic fertilizers can lead to nutrient runoff into water bodies, causing pollution and disrupting aquatic ecosystems.
30. How can planting trees help in soil conservation?
Tree roots help anchor the soil, reduce erosion, improve soil structure, and increase water infiltration, promoting soil health and conservation.
31. What is the significance of soil organic matter in agriculture?
Soil organic matter improves soil structure, provides nutrients to plants, retains moisture, supports beneficial soil organisms, and helps in preventing soil erosion.
32. What is the best way to prevent soil erosion in farms?
Planting cover crops helps to protect the soil from erosion by keeping the soil covered and preventing it from being washed or blown away.
33. Which practice helps in improving soil fertility?
Crop rotation involves planting different crops in the same area in different seasons, which helps to improve soil fertility and reduce the build-up of pests and diseases.
34. What is the purpose of adding organic matter to the soil?
Adding organic matter such as compost or manure to the soil helps to improve soil structure, increase its fertility, and provide essential nutrients for plant growth.
35. Which farming method helps in reducing soil pollution?
No-till farming is a farming method that avoids disturbing the soil through tilling, which helps to reduce soil pollution by minimizing erosion and nutrient runoff into water bodies.
36. Which practice improves soil aeration and drainage?
Adding organic matter to the soil helps to improve soil structure, promote soil aeration, and enhance drainage by increasing the presence of air pockets in the soil.
37. What is the effect of using too much chemical fertilizer on soil health?
Using too much chemical fertilizer can lead to nutrient leaching, where the excess nutrients wash away from the soil and pollute water bodies, causing harm to the environment.
38. Which practice helps in preventing soil compaction?
Adding mulch, such as dried leaves or straw, to the soil helps to reduce compaction by acting as a cushion and protecting the soil from heavy machinery or foot traffic.
39. What is the impact of soil erosion on agriculture?
Soil erosion can lead to the loss of topsoil, essential nutrients, and water-holding capacity, which in turn reduces crop yields and agricultural productivity.
40. Which farming practice helps in conserving soil moisture?
Applying mulch to the soil helps to conserve soil moisture by reducing evaporation, maintaining soil temperature, and preventing water runoff, thereby promoting plant growth and health.
41. What is the impact of soil pollution on human health?
Soil pollution can contaminate food crops with toxic substances, heavy metals, or chemicals, posing health risks to humans who consume polluted food, resulting in various health issues.
