Circuitous pattern

1. In a circuitous pattern the machine begins working along a boundary. It continues along the other boundaries of the land, returning to its starting point. 2. This pattern works from the outside to the center of the field and is the most commonly used system for ploughing in Asia. 3. It is commonly used with moldboards, discs and offset discs. This is the system that most animals are accustomed t

Tillage Patterns

An optimal tillage pattern reduces the time spent in non-productive work. One of the most important objectives of a tillage pattern is to minimize the number of turns and maximize the length of the tillage runs. There are several patterns that can be used when tilling a field. These are 1. Circuitous pattern. 2. Up and back or headland pattern 3. Land system

Upland Tillage

1. Upland tillage is undertaken in locations where crops are grown in aerobic soil conditions. This means that the soils are non-puddled soils and there is no freestanding water in the fields. Soil moisture levels are critical when ploughing in an upland-farming situation. 2. If the soil is too dry it will not till easily, the power requirement will increase and in clay soils large clods may be formed. In clay soils these large clods may cause problems when trying to decrease ped size to creat

Secondary Tillage

Secondary tillage is any working completed after primary tillage and is undertaken for • Reducing ped size, • Weed control, • Incorporation of fertilizers, • Puddling and • Leveling soil surface. Secondary workings are usually shallower and less aggressive than primary tillage. In the animal powered system, the second working is normally undertaken with the moldboard plough when the field is fully saturated. The final workings are then completed using peg tooth harrows to puddl

Primary Tillage

1. Primary tillage is the first working after the last harvest and normally the most aggressive tillage operation. 2. It is normally undertaken when the soil is wet enough to allow the field to be ploughed and strong enough to give reasonable levels of traction. 3. This can be immediately after the crop harvest or at the beginning of the next wet season. When there is sufficient power available some soil types are ploughed dry. The objectives of primary tillage are: 1. Till the soil to at

The objectives of Tillage

• Decrease ped or clod size • Remove, incorporate or modify plant residue • Manage soil water (both wetting and drying) • Control weeds • Mix and incorporate soil amendments such as lime and basal fertilizer • Control or destroy insects, their eggs, larvae and breeding places • Reduce wind and water erosion by leaving a rough surface.

The components of land preparation

The aim of land preparation is 1.To place the soil in the best physical condition for crop growth 2. To ensure that the soil surface is left level Land preparation is a combination of tillage practices that places the soil in the best physical condition for plant establishment and crop growth. To attain this condition 3. Soil must be tilled to a depth so plants can develop a root system which will physically support the plant and also allow the extraction of sufficient moisture and nut

Land Preparation

There are five parts in understanding good land preparation. These components are an understanding of the: 1. Role of tillage and land leveling in land preparation 2. Reasons why good land preparation is important 3. Different systems and equipment that are used for tillage 4. Power requirements for tillage of different soil types using different equipment 5. Basic setting up and operating equipment After any study of land preparation there should be good understanding of differ
