Dekkevekster

Dekkevekster, also known as cover crops, are plants grown primarily to manage soil erosion, improve soil health, and enhance agricultural productivity. They are typically planted during off-seasons or between main crop cycles. The main purposes of dekkevekster include preventing wind and water erosion by covering the soil surface, suppressing weeds by outcompeting them for resources, and improving soil structure through root activity and the addition of organic matter when incorporated back into the soil.

Different types of dekkevekster are chosen based on specific goals. Leguminous cover crops, such as clover or vetch, fix atmospheric nitrogen, enriching the soil with this essential nutrient. Non-leguminous types, like rye or oats, are excellent at scavenging residual nutrients from the soil and preventing their leaching. Some dekkevekster are also used to break up compacted soil layers with their deep root systems.

The management of dekkevekster involves deciding when and how to terminate them, either by plowing them into the soil (green manure), leaving them on the surface as mulch, or using specialized termination methods. The choice of termination method can influence decomposition rates and nutrient availability for the subsequent cash crop. Integrating dekkevekster into crop rotation systems is a widely recognized sustainable agricultural practice that contributes to long-term soil fertility and resilience.
