Optimum time for ploughing
The right time for ploughing depends on availability of soil moisture.
When the soil is too dry, it is difficult to open the soil, more energy is required and large sized clods are resulted.
When the soil is ploughed under wet conditions, with more soil moisture, the soil sticks to the plough, the soil below the plough-sole becomes compacted.
Upon drying, hard pan is created, soil structure is destroyed and the clods on drying become very hard.
The optimum range of soil moisture for better ploughing is 25 to 50% depletion of available soil moisture.
