Seed Drills By Metal India

Functionality The Seed Drills allows farmers to sow seeds in well-spaced rows at specific depths at a specific seed rate; each tube creates a hole of a specific depth, drops in a seed, and covers it over. Prior to this farmers simply cast seeds on the ground, by hand, for them to grow where they landed (broadcasting). This invention gave farmers much greater control over the depth that the seed was planted and the ability to cover the seeds without back-tracking. This greater control meant that seeds germinated consistently and in good soil. The result was an increased rate of germination, and a much-improved crop yield (up to eight times [1]). A further important consideration was weed control: in the days before selective herbicide, drilling afforded the ability to hoe the crop during the course of the growing season. Weeding by hand is laborious and poor weeding limits yield. [edit] Drilling "Drilling" is the term used for the mechanised sowing of an agricultural crop. The seed from the hopper of a seed drill is distributed by a seed metering mechanism into a set of tubes arranged to provide a suitable distance between each other to allow optimum growth of the resulting plants. The seed falls into "drills", or channels made by a coulter.
