Enjoy the winter to feed the garden and the garden by bringing organic matter to form a humus. This bottom fertilization makes it possible to partially restore the elements taken from the soil during the previous season.
Any crop causes depletion of the soil. This degradation must be compensated. Winter is the ideal time to improve the soil structure and enrich it by bringing it manure and amendment. Do not make this intake when it is freezing, raining or the soil is too wet.
To feed the plants, it is necessary to feed the soil by bringing it regularly organic matter, leaves, straw, compost. Once decomposed, they are transformed into humus by the flora and the microfauna. In the manner of a sponge, the humus fixes the mineral elements absorbable by the plants and then delivers them to them according to their needs. Without humus, this organic matter would be leached at the time of the rains.
To maintain a good rate of humus, we spread during the bad season, organic matter: composted manure, castor cake. In addition to enriching the soil, manures, also called organic amendments, improve the texture that arises from the way in which sands, clays and other mineral particles agglomerate. The role of the amendments is therefore to improve the physicochemical qualities of the earth. According to this, you will bring crushed limestone, bentonite.
Fertilization, it is not according to the nature of the earth but according to the planned crops. You will have the choice between a natural, organic or mineral fertilizer. Its role is to enrich the soil with nutrients. It usually applies at the end of winter, a few weeks before sowing or planting.
Improve and enrich the soil
The amendments refer to products not used to feed the soil (such as fertilizers), but to improve the physicochemical qualities of the soil. The mineral amendments (basalt, dolomite …) overcome the defects of heavy, light, acidic or calcareous soils.
Organic amendments (manure, compost …) contribute to the production of humus. This material that binds clays aggregates silts and sands, retains water and tempers acidity like the basicity of the soil.
“Natural” fertilizers, whether of organic origin (beet vinasse, feather powder …) or mineral origin (crushed rocks), provide the soil with nutrients that can not be used directly by the plants. They are “digested” by micro-organisms, stored by the humus before being absorbed by the plants as and when they are needed.
The manure is animal bedding: straw mixed with manure. Fresh, so it’s a very rich carbon and nitrogen amendment. It is usually marketed composted or fresh, but dehydrated.
When choosing a “natural” fertilizer , carefully read the labels on the package. Only the mention “usable in organic farming” and the label of a control body offer the guarantee that the product marketed does not contain substance derived from synthetic chemistry.
