Autumn soil cultivation in a greenhouse is a critical stage in preparation for the next season.
Proper soil care allows you not only to preserve, but also to significantly increase its fertility, creating ideal conditions for future plantings.
Deep soil cleaning
Soil preparation begins with the careful removal of the root system of old plants, reminds the expert of the online publication "BelNovosti", scientist-agronomist and landscape designer Anastasia Kovrizhnykh.
Gardeners recommend digging up even the smallest roots, which can become a source of disease spread. The top layer of soil is carefully dug to a depth of 25-30 centimeters.
Soil disinfection
Soil disinfection is considered a mandatory procedure. Various methods are used for disinfection: pouring the soil with a solution of potassium permanganate, treating with biological preparations or steaming.
Some gardeners use a dry disinfection method by scattering wood ash over the surface of the soil.
Restoring soil structure
After disinfection, they begin to improve the soil structure. Sand, peat or humus are added to the soil, evenly distributing the components over the entire area of the greenhouse.
An important point is to determine the acidity of the soil and, if necessary, apply lime.
Fertilization
Autumn fertilization plays a key role in increasing fertility. Organic fertilizers are incorporated into the soil during digging.
Compost or humus is distributed in an even layer, phosphorus and potassium fertilizers are added. Nitrogen fertilizers are not applied in the fall, leaving this procedure for the spring.
Sowing green manure
Many experienced gardeners practice sowing green manure after the main crops. Mustard, phacelia or rye enrich the soil with nitrogen, improve its structure and suppress the growth of weeds.
In spring, the green mass is added to the soil, producing excellent organic fertilizer.
Mulching the surface
The final stage of soil preparation is mulching. Compost, humus or peat are used as mulch.
A layer of mulch protects the soil from freezing, retains moisture and prevents weed growth.
Organization of drainage
Proper organization of the drainage system prevents moisture stagnation in the soil.
Drainage channels are laid along the perimeter of the greenhouse and filled with crushed stone or expanded clay. Additional drainage pipes are installed if necessary.
Humidity control
Maintaining optimal soil moisture levels during the winter requires special attention.
Excessive humidity leads to the development of pathogenic microorganisms. Regular ventilation of the greenhouse helps maintain a favorable microclimate for soil microflora.
