Tillage is the process of soil manipulation to improve soil health and develop a suitable structure to make a seedbed before sowing seeds. Soil tillage allows farmers to create perfect seedbed with controlled weeds, removes crop residues, minimizes soil erosion and also establishes the perfect upper layer for planting crops etc. Tillage operations that needs to be performed to make a seedbed are usually done in primary and secondary steps. Primary tillage initial includes significant some significant steps normally designed to loosen the soil.
While, secondary tillage operations are needed to create refined soil structure for making final seedbed for planting crops. Usually a mould-board plough is the most common agriculture equipment used for creating seedbed. But we can say that in modern times a Rotary tiller or rotavator is preferably used as a nowadays when it comes to prepare a desired seedbed.
Rotary Tiller and Its Uses in Tillage
To reduce the use of mechanical energy and labor work in soil it is necessary to use the minimum tillage system to manipulate soil. Perfect tillage system allows to preserve the natural moisture in the soil by minimizing the number of rounds on a farm. To avoid extra soil tillage a Rotavator is the perfect agricultural machinery which is used as a minimum tillage system. The high quality of soil pulverization also makes the best machinery to use for seedbed preparation.
Rotary Tiller uses rotating blades also known as rotors to churn up the soil. The rotor or rotating blades generally rotates in the similar direction that of tractor wheels. Each blade cuts a section of soil as it moves downward in the direction of the rear wheels. Mostly rotavators make 2 or 3 cuts in the soil per round.
A Rotary tiller can also be used for uprooting the previous crop residue and mixing it on the upper layer of the soil. It a popular and widely used machinery specifically for rice crops in most of the Asiatic countries. Rice fields in such countries are usually ploughed by underwater tillage.
More versatility and reduced draft requirements to obtain a desired outcome in manipulating the soil are the two reasons for considering such more complex farm equipment.
