Direct seeding of corn: features of the technology
The importance of introducing sustainable technologies to agriculture is growing rapidly. One promising solution is direct seeding, a method that preserves soil structure and quality. Also known as no-till technology, direct seeding is in high demand in arid and erosion-prone regions.
Direct seeding effectively retains moisture in the soil. Studies confirm its many advantages over traditional cultivation methods:
— no-till farming keeps the soil temperature three degrees lower at a depth of 10 cm;
— these results are maintained throughout the growing season;
— soil loss on slopes is 2.6 times lower compared to areas cultivated using traditional methods.
Spanish experience: how Cobideza scales the technology
The Cobideza cooperative in Spain is one of the leaders in the implementation of no-till farming. For the second consecutive year, the cooperative has used the direct seeding method for corn. In 2024, the cooperative planted 40 hectares with this technology. The following year, the area increased to 80 hectares.
Roman Santalla from Cobideza noted that no-till technology saves money on land cultivation. Additionally, it helps reduce erosion, which is especially important for plots located on slopes.
Government support provides additional motivation for farmers. Direct sowing is included in the European Union’s Common Agricultural Policy (CAP) program. Under this initiative, farmers receive €86 compensation for each hectare sown using no-till technology.
For farmers in some Spanish regions, reducing erosion is a major concern. Much of their land is on slopes, which accelerates soil degradation. Traditional plowing exacerbates the problem, making the soil more susceptible to erosion. Direct seeding, on the other hand, creates a natural barrier of plant residues that helps corn withstand heat and drought.
Despite the technology’s many advantages, it also has drawbacks. The main drawback is a reduction in yield, though not by a significant amount. Nevertheless, farmers are willing to accept this fact because the advantages of no-till farming outweigh the disadvantages.
What is this technology
Direct corn sowing technology involves completely abandoning soil plowing. Agronomists follow this plan instead:
1. Weed control — before or right after planting, they use glyphosate to kill weeds. This is a key step because weeds cannot withstand mechanical destruction when the soil is not plowed.
2. Application of organic fertilizers — manure slurry is applied to the soil, enriching it with nutrients.
3. Sowing with specialized equipment — a seeder ensures the precise application of seeds, fertilizers, and other substances necessary for corn growth.
4. Nutrient control — it is especially important to monitor the nitrogen level in the soil throughout the growing season. A lack of nitrogen can affect yield.
The key factors for success in direct seeding are strict adherence to the technological stages. It is equally important to regularly monitor the condition of the soil and vegetation.
