Lesson Content/Board Summary

Farmland Preparations

Meaning of Farmland Preparations

Farmland preparation refers to all the operations carried out on the land from the time the previous crop is harvested or the land is fallow until the new crop is planted. The main goal is to create a suitable seedbed for planting, improve soil structure, control weeds, and ensure proper aeration and water infiltration.

Types of Farmland Preparations

Farmland preparation involves several distinct operations, each contributing to creating an ideal environment for crop growth. These operations are typically carried out in a specific sequence.

1. Clearing: This is the initial stage of farmland preparation, especially for land that has been fallow or covered with natural vegetation.
   1. Field Context: Clearing involves removing unwanted vegetation such as bushes, shrubs, trees, and weeds from the farm site. It can be done manually using hand tools or mechanically using heavy machinery.
   2. Observable Characteristics: The land surface becomes free of large plant debris, making it accessible for subsequent operations. Stumps and roots may also be removed to facilitate tillage.
   3. Practical Management Considerations: Burning cleared vegetation should be done carefully to avoid soil nutrient loss and environmental pollution. Mechanical clearing is faster but can lead to soil compaction if not managed properly.
2. Ploughing: This operation involves breaking up and turning over the soil to a certain depth. It is a primary tillage operation.
   1. Field Context: Ploughing loosens the soil, incorporates organic matter, and buries weeds and crop residues. It can be done using animal-drawn ploughs or tractor-drawn ploughs.
   2. Observable Characteristics: The soil surface is turned over, exposing fresh soil. Large clods of soil are typically visible after ploughing. The depth of ploughing varies depending on the crop and soil type.
   3. Practical Management Considerations: Ploughing should be done when the soil moisture content is optimal (neither too wet nor too dry) to prevent the formation of hard clods or soil compaction. Contour ploughing is used on slopes to prevent erosion.
3. Harrowing: This is a secondary tillage operation performed after ploughing.
   1. Field Context: Harrowing breaks down the large clods of soil left by ploughing into finer particles, levels the soil surface, and further incorporates organic matter and fertilizers. It is usually done with harrows, which can be disc harrows, spike-tooth harrows, or spring-tooth harrows.
   2. Observable Characteristics: The soil surface becomes much finer and more level compared to after ploughing. The seedbed appears more uniform and crumbly.
   3. Practical Management Considerations: Multiple passes of harrowing may be needed to achieve the desired seedbed tilth, especially in heavy soils. It helps in weed control by uprooting young weeds.
4. Ridging: This involves creating raised beds or ridges in the field.
   1. Field Context: Ridging is done for specific crops like yam, cassava, potatoes, and some vegetables. It improves drainage, provides a deeper soil layer for root development, and makes harvesting root crops easier. It can be done manually with hoes or mechanically with ridgers attached to tractors.
   2. Observable Characteristics: Distinct raised mounds or continuous rows of soil are formed across the field. The furrows between the ridges serve as drainage channels.
   3. Practical Management Considerations: The height and spacing of ridges depend on the crop requirements and soil type. Ridging helps in controlling soil erosion on gentle slopes by directing water flow. It also facilitates irrigation in some systems.
