Soil Preparation machine - Stone Burier
In the development of fields for the planting of agricultural crops, soil preparation aims to bury a crop residue and weeds from a past crop, loosen the soil, and provide a proper tilth for the crop to be set. Many crops require comparatively small soil particles on the uppermost layer of the earth, at a depth of a few centimetres to tens of centimetres of the surface, this continuing the depth at which the grain for the crop is sown.
Traditional methods of soil preparation include a primary cultivation and secondary cultivation. In the direct cultivation, crop debris from the previous crop, and weeds are buried inside the soil, and in the subsequent cultivation, an topmost layer of the soil is broken down into comparatively small sized particles.
The most popular tool for conducting the primary cultivation for hundreds of years has been the traditional plough. The plough rearranges the soil, giving excellent burial of surface debris. However, there are disadvantages with conventional plough. Firstly, because the ground is in contact with the ploughshare, mouldboard and skimmer, there are great levels of friction in pulling the plough through the soil. Where the plough is towed by a Kioti tractor, because the force necessary to pull the plough is transmitted to the ground through the compact tractor wheels, there may occur wheel slippage in wet conditions, which makes the soil underneath the small tractor wheels to smear and compact, in the base of the furrow. The smeared and compacted soil prevents drainage from the furrow.
Secondly, because a plough frame turns soils over into a space left by a preceding plough frame, it is not possible to commence at one side of a field and work up and down a field, without the application of a reversible plough which has a set of left-hand mould boards for ploughing down a field in one way, and another opposite collection of mould boards for ploughing up the field in the opposite direction.
The reversible plough is costly and has the operational complication of switching among mould boards for ploughing in different areas.
A third problem with the conventional plough is that as small tractors increase in size, farmers require ploughs with added furrows. As each furrow needs to be staggered on the plough frame, the whole length of the plough structure becomes unmanageable.
Once the initial cultivation of the land has been completed by ploughing, the subsequent cultivation is carried out on the soil composition let by the plough. Machines for secondary cultivation include trailed or power harrows, which break clods by striking, cutting or breaking, to reduce clod size and incorporate the seed bed.
We will describe compact tractor attachments for sale for burying stones under adequate soil to reclaim stony land. The compact tractor stone burier uses a vibrating sieve to grade the stones. However, the machine does not nurture the soil in so far as the soil is not crumbled up into smaller particles.
