Mind map on ploughing
Answers
Answer:
Optimum depth of tillage operations is required for better yield of crops. Soil profile including moisture content, compactness and texture affects the depth of operation. Farmers using the bullock drawn plough try to maintain the depth of operation based on their experience, however it is very difficult to know the variation until it is too much. Therefore, there is need of developing a low cost sensor and alarm system, which may give alarm, if there is variation in depth of operation. The farmer can accordingly adjust the depth of ploughing by adding/removing weight on the plough or changing the angle of beam.
There is need of developing a low cost sensor which can be used to sense depth of operation irrespective of tillage implements (plough, harrow, cultivator, seed drill, etc.) and alarm in case the variation is beyond the pre-set limits.
Sensor Guidelines
The sensors and alarming system should be low cost, robust enough to work in agricultural fields.
The attachment should easily be fitted with the existing tractors and its attachments (tillage implements)
The unit should consume minimum power; preferably it should have its own power source
The unit should have provision of setting the optimum depth of operation and allowable variation, which user may adjust according to type of crop
The unit should be compact in design and light weight.
