The most convenient and cheapest type of organic fertilizer.
An annual oil plant from the Cruciferae family, which has the ability to release poorly soluble phosphates.
Can grow on any soil: with a pH from very acidic to alkaline.
Seeds germinate at a temperature of +3°C. Seedlings withstand short-term frosts down to -5°C.
Mustard sprouts quickly and grows quickly. The green mass is mown when the plant leaves are fresh, juicy, better before mass flowering, because when harvesting at a later date, the leaves will begin to die off and the organic mass will decrease, and the ripened seeds will clog the bed.
On average, the period from sowing to incorporating mustard into the soil is 55-70 days (8-10 weeks). It is better to incorporate it into the soil or dig it in a little (by autumn everything will have rotted).
Seeding rate: 2.5-4.0 g/m2.
Soil planting depth: 2-3 cm (sow lightly, raking into the soil). The next crop is planted no earlier than 3-4 weeks after the green mass has been planted.
The phytosanitary effect of mustard is also important - after its planting, the incidence of such common plant diseases as late blight, rhizoctonia, tuber scab, fusarium rot, including potatoes, decreases.
Mustard crops reduce the number of wireworms in the soil; it is also recommended to plow white mustard in late autumn; as a result of disruption of the wireworm's wintering, it dies. To increase the effectiveness of wireworm control, the mustard seeding rate is increased to 5.0 g/m2.
In recent years, many farmers have refused to use manure. It is difficult to obtain it in the required quantities, it is labor-intensive and expensive. Moreover, the area is infested with weeds (in case of using manure) and will require the use of herbicides or exhausting weeding. In this case, green manure will serve as a serious alternative to manure.
Green manure is understood as green manure crops, the fresh plant mass of which is used as fertilizer (plowed in) to enrich the soil with organic matter.
1.0 g = 145-150 seeds.
* What are the benefits of siderates?
Siderata stop the leaching of nutrients outside the root layer, pump nutrients from the deep horizons of the soil into the upper layer, and contribute to the accumulation of humus in the soil, which improves its properties. The more humus is contained in the soil, the lower its thermal conductivity and higher heat capacity, less physical evaporation of water from it, more productive use of soil moisture by cultivated plants. Humus contributes to the intensive development of beneficial soil microflora.
The biomass of the root systems of herbaceous plants plays an important role in enriching the soil with organic residues. When green fertilizer is applied, not only nitrogen, but also other nutrients are accumulated in the soil. Green fertilizer in the soil decomposes much faster than other organic fertilizers rich in fiber. Green fertilizer slightly reduces the acidity of the soil, significantly increases the permeability and moisture capacity of the soil, as a result of which the surface runoff of precipitation decreases and the moisture content in the soil increases sharply. As a green fertilizer (siderates), the following are mainly cultivated: lupine, sweet clover, mustard, alfalfa, phacelia.
