Why is it important to loosen the soil before growing a crop?
Why is it important to loosen the soil before growing a crop?
- To allow roots to penetrate deep and breathe easily (correct)
- To increase the temperature of the soil
- To prevent waterlogging and soil erosion
- To reduce the presence of earthworms and microbes
What is the role of earthworms and microbes in the soil?
What is the role of earthworms and microbes in the soil?
- They hinder plant growth by competing for nutrients
- They reduce soil fertility
- They aid in compacting the soil
- They help in turning and loosening the soil (correct)
What happens when dead plants and animals get decomposed by soil organisms?
What happens when dead plants and animals get decomposed by soil organisms?
- The soil pH increases
- The soil becomes more compact
- Nutrients are released back into the soil (correct)
- The soil loses its fertility

Study Notes
Soil Composition and Nutrient Cycle
- Soil is composed of minerals, water, air, and living organisms
- Dead plants and animals are decomposed by soil organisms, releasing nutrients back into the soil
- These nutrients are absorbed by plants, enabling them to grow
Importance of Soil Turning and Loosening
- Only a few centimeters of the top layer of soil support plant growth
- Turning and loosening of soil bring nutrient-rich soil to the top, making it accessible to plants
- This process is essential for cultivating crops
Soil Tilling or Ploughing
- Tilling or ploughing involves loosening and turning of soil to bring nutrient-rich soil to the top
- Ploughs are used to till the soil, and they can be made of wood or iron
- Soil may need watering before ploughing if it is very dry
- Ploughing can result in big clumps of soil called crumbs, which need to be broken
- Levelling the field after ploughing is beneficial for sowing and irrigation
