Mechanical sowing refers to the placement of seeds into the soil by an agricultural machine or manually operated (but mechanical) device. Mechanical sowing, also referred to as mechanical seeding, is generally practiced in areas where there are constraints to labor availability or where farmers want to reduce the drudgery of planting seed by hand. It is typically utilized for cereal crops, but can also be applied to legumes and many other crops, including rice. When farmers or agricultural machinery service providers – people who own seeding machinery and rent out its use on an affordable fee-for-service basis – practice such seeding, the geometry of crop placement tends to be precise, so long as the machine is well calibrated, and correctly used and maintained (topics that are covered in this learning module). While mechanical seeding may not always result in increased yields, it does tend to save labor costs for farmers, and thus profit increases where yields are maintained compared to hand-sown seed. Further savings may result when farmers use mechanical seeding equipment that tills or prepares the soil at the same time as it sows seed, or where tillage is foregone, as in zero-till and conservation agriculture systems.
