Ploughing Ploughing is the process of opening the soil with the help of plough. Ploughing is the principal tillage operation, which aim to produce a good tilth required for making a good seed bed and providing better soil condition for plant growth.
Principles of ploughing Ploughing at the right moisture condition (zoe condition). 4WD tractor or when ploughing less than 7in deep, equal front and rear wheel settings can be advantageous as it helps to ensure the tractor and plough pull in a straight line.

The purpose of ploughing can be summarized as follows ♦ To obtain a deep seed bed of good texture. ♦ To increase the water holding capacity of the soil. In many urban areas, drainage is based on a completely artiﬁcial system of sewers: pipes and structures that collect and dispose of this water.
In contrast, isolated or low-income communities normally have no main drainage.

If it is too wide and deep it will require excessive after-cultivation to fill it in. Publications on establishment and maintenance (forest operations) Publications about ground preparation, drainage, planting, protection, weeding and establishment and maintenance of quality crops using appropriate silvicultural systems.
Water, sanitary and waste services represent a substantial proportion of the cost of construction, averaging 10% of the capital costs of building and with continuing costs in operation and maintenance. Nevertheless, they are often regarded as a 'Cinderella' within the building process.
The intensity of primary tillage influences the impact of seedbed and sowing operations on soil properties and plant growth. Owing to higher soil strength, a soil under reduced tillage supported a soil compaction in spring to a higher degree than a soil under deep ploughing to 25 cm soil depth (Wiermann et al., ).Cited by: 6.
A plough or plow (US; both / p l aʊ /) is a farm tool for loosening or turning the soil before sowing seed or planting. Ploughs were traditionally drawn by oxen and horses, but in modern farms are drawn by tractors.
A plough may have a wooden, iron or steel frame, with a blade attached to cut and loosen the soil. Tillage Equipment Pocket Identification Guide Tillage Systems-Primary Tillage- Secondary Tillage- Some chisel plows are equipped with a gang of coulters or disk blades mounted in front to cut residue.
the more that operation will disturb the soil. Fully renewed and extended, this edition is a valuable source of information for anyone involved in drainage engineering and management. It provides new theories, technologies, knowledge and experiences in combination with traditional land development practices in the humid temperature zone.
Aspects covered include: management and maintenance; drainage. Normal drain depth is around mm below the soil surface. For subsoiling to result in improved drainage, the depth to which the soil is loosened must be just greater than the depth down to the top of the permeable backfill.
This will connect the fissures and allow water to move to the permeable fill over the drains. SECTION 2 EARTHWORKS Standard Specification for Urban Infrastructure Works Edition 1, Revision 0 / September (iii) Minimise the area exposed by: • staging of clearing operations • progressive stabilisation of the works as completed • provision of temporary grassing • contour ploughing to disturbed areas.
Plough - Ploughing is the primary tillage operations, which are performed to cut, break and invert the soil partially or completely. Ploughing essentially means opening the upper crust of the soil, breaking the clods and making the soil suitable for sowing seeds.
