Tõrjerikkus

Tõrjerikkus, also known as "tõrjepõllundus" or "tõrjepõllumajandus," is a farming practice that involves the use of crop rotation and the planting of cover crops to improve soil health and fertility. This method is particularly prevalent in Estonia, where it has been a traditional farming practice for centuries. The term "tõrjerikkus" translates to "turning richness" or "rotational richness," reflecting the cyclical nature of the practice.

The core principle of tõrjerikkus is to alternate crops in a specific sequence over several years. This rotation helps to replenish the soil with essential nutrients, reduce the risk of pests and diseases, and improve overall soil structure. Common crops used in this system include cereals, legumes, and root crops. Legumes, in particular, are valued for their ability to fix nitrogen in the soil, enhancing its fertility.

Cover crops, such as clover and vetch, are also an integral part of tõrjerikkus. These crops are planted between the main crop seasons to prevent soil erosion, suppress weeds, and add organic matter to the soil. By incorporating these practices, farmers can achieve sustainable agriculture that supports long-term soil health and productivity.

Tõrjerikkus has been recognized for its environmental benefits, including improved water retention, enhanced biodiversity, and reduced chemical inputs. It is often cited as a model for sustainable farming practices that can be adopted in various agricultural systems around the world. Despite its traditional roots, tõrjerikkus continues to evolve, incorporating modern techniques and technologies to maintain its effectiveness and relevance in contemporary agriculture.
