Some of the benefits of direct seeding are more readily seen than others. Time savings and moisture management may be seen in the first year. Soils, however, take time to adjust to the new system. Many farmers note that it takes two or three years to see improvements in soil tilth and water infiltration. It takes time for soil organic levels to reach a new equilibrium.
Crop rotation is more important in direct seeding than in conventional seeding.
In most cases it is an essential tool in fighting disease, insects and weeds. It prevents build-up of diseased residues and allows for better control of weeds, volunteer crops and insect pests. There is potential for foliar diseases to become worse under direct seeding versus conventional seeding. Many disease-causing organisms overwinter on crop resdues and often do better under the moist, cool conditions found in direct seeding. When direct seeding more emphasis needs to be put on crop rotation, crop varieties, seed quality, treated seed, timing of seeding, weed control, fertility, foliar fungicides and crop residue management.
