Direct
Seeding
Direct seeding
is a relatively new approach to seeding. Direct seeding, like no-till, is a
cropping system whose purpose it is to improve soil and soil moisture
conservation. Unlike no-till, direct seeding is more flexible, allowing the
utilization of some tillage to solve weed problems, high moisture, and heavy
clay soil conditions.
In direct
seeding, soil is not tilled in the spring before planting. This is to conserve
soil moisture in the seedbed. The soil surface must be compact and level to
preserve soil moisture. Most of the crop residue remains on the surface with at
least half the stubble remaining upright and anchored to trap as much snow as
possible.
Typical
operations are fall fertilizer banding with knives, and redistributing crop
residue and incorporating herbicides with heavy or rotary harrows. The amount of
soil disturbance during direct planting varies with the type of opener.
