suorakylvö

Suorakylvö, also known as no-till farming or direct seeding, is a conservation tillage practice where crops are planted directly into the residue of the previous crop without prior plowing or disking. This method minimizes soil disturbance, unlike conventional tillage which involves extensive soil manipulation.

The primary goals of suorakylvö are to improve soil health, reduce erosion, and conserve soil moisture. By leaving crop residues on the soil surface, it acts as a protective mulch, shielding the soil from wind and water erosion. This surface cover also helps to retain moisture by reducing evaporation and can lead to increased organic matter content in the soil over time.

The benefits extend to reduced fuel consumption and labor costs associated with fewer tillage passes. Suorakylvö can also contribute to improved soil structure, increased biodiversity within the soil ecosystem, and enhanced nutrient cycling. However, successful implementation often requires careful management of crop residues, effective weed control strategies (which may involve herbicides), and attention to seed-to-soil contact to ensure good germination. The practice has gained traction globally as an environmentally sustainable agricultural method.
