Importance of Soil Preparation
- Soil as a Source: Provides minerals (potassium, phosphorus, sulphur, nitrogen), water, etc.
- Loosening Soil:
- Allows roots to penetrate deeply
- Helps roots to breathe, absorb water and nutrients
Benefits of Loosening Soil
- Promotes growth of earthworms and microorganisms
- Earthworms help create humus, improving soil fertility
- Enhances nutrient availability for plants
Steps in Soil Preparation
- Ploughing (Tilling)
- Performed using a plough
- Mixes nutrient-rich subsoil with topsoil
- Ensures proper seed placement and growth conditions
- Leveling
- Even distribution of soil to support plant growth
- Adding Manure and Fertilizers
- Done before tilling to ensure even distribution
Tools Used in Soil Preparation
- Plough:
- Traditional tool, used since ancient times
- Made of wood with iron ploughshare
- Pulled by animals like bulls
- Hoe:
- Used for removing weeds and soil loosening
- Contains a long rod with a blade, pulled by animals
- Cultivator:
- Modern, tractor-driven
- Saves time and labor
