Living Mulch: Advantages of White Clover for Interrows and Soil Protection
The use of living mulch in interrows is gradually replacing traditional methods of weed control, such as frequent tilling or the use of herbicides.

Modern agricultural technologies recommend sowing low-growing ground cover crops, particularly white clover (for example, the variety “Rivendell”), which is ideal for creating “living mulch.” This approach not only protects the soil from drying out and erosion but also transforms interrows into a natural system for maintaining fertility and conserving moisture.
Nitrogen Support and Optimal Microclimate for Plants
Unlike straw mulching, which over time contributes to soil acidification, white clover, thanks to the nodulating bacteria on its roots, accumulates nitrogen from the air and transfers it to cultivated plants, such as tomatoes, peppers, or fruit trees. This creates a “nitrogen pump” effect, enhancing soil fertility without additional fertilizers.
Moreover, the dense green carpet regulates the temperature near the roots: during hot months, the soil under the living mulch remains 5–7°C cooler than in open areas. This significantly reduces the risk of overheating plants and allows for reduced watering, as the dense cover prevents moisture evaporation.
Preventing Erosion and Supporting Natural Balance
A constant plant cover in interrows serves as a reliable barrier against water and wind erosion, which is especially important for open lands. Even during heavy rainfall, the soil does not wash away, remaining loose and structured.
Another advantage is the attraction of beneficial insects. Flowering clover attracts bees and entomophages—natural enemies of pests that help maintain the biological balance in the garden or vegetable patch. Thus, the need for chemical plant protection products is reduced, and the area gains a well-kept appearance, becoming part of a sustainable ecosystem.
“The technology of sowing and caring for living mulch. To create an effective cover, it is recommended to sow seeds early in the spring in well-moistened soil. The optimal sowing rate for white clover is about 10–12 grams per hundred square meters.”
The main principle of care is to mow the clover once during active growth (when the plants reach 10 cm). This stimulates the development of the root system and promotes the release of nitrogen into the soil. Living mulch is perennial and does not require annual reseeding, making it particularly valuable for organic farming and sustainable management.
