In agriculture. Drilling is the plan of sowing seeds in parallel rows as distinguished from sowing them broadcast. The drilling method of sowing was introduced into England by Jethro Tull, who published a work on the subject in 1731. The crops which are now generally drilled are turnips, potatoes, beans, pease, carrots, clover, cereals, flax, etc. The first form of drill was of very simple construction, and was only adapted for sowing one row at a time, but now a great variety of improved implements are in use. Among the principal advantages of drilling over broadcast sowing we may mention that a considerable saving of seed is effected in the sowing of grain crops, but the great advantage is that in the case of green crops it enables the farmer more readily to clean the land both by the hand and by mechanised hoes. To keep the soil stirred and pulverized, which can only be properly done when the crops have been drilled, favours the retention and absorption of the moisture. Research Drilling
