Question

What is the importance of humus?

Answer 1

1. Enhances Nutrient Supply: It acts as a reservoir for vital plant nutrients such as nitrogen, phosphorus, and sulfur.
2. Improves Soil Structure: It binds loose soil particles together, increasing soil aeration and root penetration.
3. Increases Water Retention: It acts like a sponge, considerably boosting the soil's ability to retain moisture.
4. Prevents Soil Erosion: It improves soil aggregation, making the soil less vulnerable to being washed away by wind or rain.
5. Supports Soil Organisms: It supports soil organisms by making food and energy for beneficial soil microorganisms and earthworms.
6. Regulates Soil Temperature: Its dark colour absorbs heat efficiently, assisting in maintaining optimal soil warmth for seed germination.
7. Buffers Soil pH: It prevents rapid changes in soil acidity or alkalinity, making the soil stable for plants.
