The larger 5-kilogram package of white mustard seeds is a practical and cost-effective choice for field plots, spacious rural properties, and landscaping near apiaries. It is a reliable and widespread cover crop that helps restore the vitality of soil depleted by intensive cultivation. The powerful root system of white mustard acts as a biological plow, breaking up compacted soil layers and mobilizing minerals found deep in the ground, which then feed subsequent crops after plowing.
In addition to improving soil structure, this crop plays a vital role in soil biofumigation and sanitation. Glucosinolates present in plant tissues create an unfavorable environment for numerous harmful fungi and pathogens as they decompose in the soil. Fast-germinating and fast-growing mustard covers the ground with dense shade, leaving minimal room for weeds to develop. For beekeepers, blooming white mustard provides valuable forage, delivering a considerable nectar yield that supports bee colonies in the second half of summer.
Usage and Cultivation Instructions:
-
Sowing time: From early spring until the second half of August. Seeds emerge quickly and produce a substantial green mass within a couple of months.
-
Sowing rate: 15–20 kg per hectare (equivalent to 150–200 g / 100 m²). Thus, 5 kg of seeds is sufficient to cover approximately 2,500–3,300 m² (25–33 ares).
-
Sowing depth: 2–2.5 cm. When sowing in a field or over a large area, ensure the seed is properly covered with soil or use a roller after sowing to promote even germination.
-
Harvesting/Mowing: For use as green manure, plow or roll the crop under just before flowering or right at the onset of bloom. This prevents seed maturation and unwanted self-seeding.
Tips and recommendations:
-
White mustard sown as an autumn cover crop can be left in the field over winter as natural mulch. Freezing temperatures kill the plants, leaving an easily workable organic layer by spring that protects the soil from erosion and moisture loss.
-
Avoid growing the crop in soils with very low pH (acidic soils), as plant growth is severely inhibited there, resulting in poor green mass yield.
