Study Notes

Importance of Soil Preparation

Preparation of soil is essential before crop cultivation.
Turning and loosening soil are critical tasks in agriculture.
Loose soil facilitates deep penetration of plant roots.

Benefits of Loosened Soil

Loose soil enhances root respiration by allowing air access.
Improved soil structure promotes the activity and growth of beneficial microbes.
Microorganisms contribute to soil fertility by aiding in soil turning and adding humus.
Humus enriches soil, improving its nutrient content and water retention.

Soil Tilling Process

Tilling or ploughing involves loosening and turning the soil to prepare it for planting.
A plough, made from wood or iron, is used for this process.

Conditions for Effective Tilling

Dry soil may require watering before ploughing to facilitate effective tilting.
Dry clumps of soil, referred to as crumbs, form in the ploughed field.

Importance of Soil Management

It's essential to break up soil crumbs to enhance soil structure and aeration.
Leveling the field is crucial for optimal sowing and effective irrigation.

Tools for Soil Preparation

A leveller is employed to ensure the soil is even, promoting better water distribution.
Manure is sometimes added before tilling, aiding in its mixture with the soil for nutrient enhancement.

Final Soil Preparation

Soil is moistened before sowing seeds to improve germination and plant growth.
