The Tropical Agriculturist. The Agricultural Journal of Ceylon November 1936

1936

The characteristic feature of a drill is the presence of seed coulters for depositing the seeds in lines under the surface of the soil. [...] - When the seed is dropped over the conical projection in the centre of the seed cup it passes into the upper seed tubes and thence to the lower ones being finally285 deposited in the shallow furrows made in the soil by the coulters. [...] The sower stands just behind the drill and as the animals start walking the seeds are dropped at a uniform rate from one hand to the top of the conical shaped projection in the centre of the seed cup. [...] The number of foot steps required for one trip from one end of the field to the other is found by driving the pair of bullocks with the drill hitched on and the sower whilst walking behind the drill counts the number of steps taken for the trip. [...] It has been found that while petrol is effective in killing most of the ants actually in the soil at the time of treatment the effect of the gas soon wears off and more ants return to the attack.
