More information

A perennial legume, to be used as green manure for several years. It has the ability to fix atmospheric nitrogen in its roots and release it back into the soil, enriching the land for subsequent crops. Its deep pink flowers are attractive to bees. The purple clover will help to loosen the soil, limit weed growth, and combat leaching of the soil or compaction caused by heavy rains. It can be sown from March to August, with vegetation destroyed from April to July or from September to October, and then buried from May to August or in October-November.

Description

The violet clover, in Latin Trifolium pratense, is a small perennial of the legume family that is used as a green fertilizer for several years or as a forage plant. Its roots have the ability to fix atmospheric nitrogen, which it will return to the soil, thus reducing the need for fertilizer. It is also a honey plant, with dark pink flowers rich in nectar that feed pollinating insects. Through its root system, it loosens the soil, limits the proliferation of unwanted weeds, and combats soil leaching or compaction caused by rain. It is sown from March to August.

The violet clover belongs to the Fabaceae family (formerly legumes) and the genus Trifolium like white clover or Alexandrine clover. These different clovers are characterized by their leaves with 3 leaflets and their ability to fix atmospheric nitrogen in the soil. The violet clover has good frost resistance and develops a significant vegetative cover. During the summer, it blooms in the form of spherical heads of dark pink color. The violet clover is suitable for all types of soils.

Widely used in organically cultivated gardens, green fertilizers like violet clover have many advantages. They feed and improve the soil by providing it with various nutrients and stimulating the soil's microbial life. Their roots will loosen, break up, and aerate the soil. Moreover, the presence of a vegetative cover protects the soil from leaching (nutrient loss in sandy soil), rain compaction (formation of a crust in loamy soil), and erosion (caused by runoff in steep terrain during heavy rain). This vegetative cover also helps limit weed growth by preventing the growth of unwanted weeds. Finally, green fertilizers are often honey plants and attract pollinators.

Green fertilizers are sown on uncultivated plots or intercalary plots, between vegetable rows. They are either naturally destroyed by frost or cut before seed formation. Once destroyed, they can be left in place as mulch, or be crushed and incorporated into the top layers of the soil, or be collected and added to compost.

White mustard: sowing, growing

Read article

Cultivated in France since the 14th century, white mustard, Sinapis alba, is an annual herbaceous plant that produces large pale yellow seeds used in the making of strong mustard. While their taste is bitter, it is less pungent than that of black or brown mustard. Grown as a green manure, Sinapis alba transforms into organic matter once destroyed by frost or by crushing, which naturally enriches the soil. White mustard covers the ground with its dense clumps, and leaves no room for weeds that it smothers. Its root system also allows water and air to penetrate the soil well, and effectively retains nitrates. This helps prevent pollution of groundwater. The roots of mustard have properties similar to garlic. They are thus a very effective and natural bactericide and nematicide. The plant therefore allows for the disinfection and sanitisation of the soil for a future vegetable garden. Mustard in general includes species from the genus Sinapis, as is the case with white mustard, and species from the genus Brassica. The Sinapis alba (white mustard) is the most suitable as a condiment, although Brassica nigra (black mustard) is also used for this purpose. Prepared mustard is generally made using a mixture of white mustard seeds and black mustard seeds, which are mixed with vinegar, must, or verjuice.

It is grown in open ground in sunny or semi-shaded conditions. Easy to grow, Sinapis alba requires very little maintenance, limited to light watering to keep the soil moist. Here are all our tips on this perfect green manure to improve the quality of your soils.
