The viability of tomato seedlings and the volume of the future harvest are laid at the stage of formation of the root system in seedling tanks. A deficiency of macronutrients or a high density of soil blocks the absorption of nutrients, turning seedlings into weak elongated threads.
The creation of a balanced substrate requires precise control of the physico-mechanical properties and acidity of the components. A proper soil matrix ensures unhindered gas exchange, retains moisture without waterlogging, and stimulates the development of a powerful network of lateral roots.
Components of the base substrate for nightshades
The basis of a high-quality seedling mixture is peat, which has high porosity and sterility from weed seeds. This component creates a loose framework that allows the delicate roots to easily penetrate deep into the container without mechanical resistance.
To enrich the matrix with organic substances, mature vermicompost or rotted leaf compost is introduced into the composition. The proportion of the organic fraction should not exceed 30 percent, otherwise excess nitrogen will provoke fattening of seedlings to the detriment of laying flower tassels.
The basic formulations of soil mixtures include the following elements:
- purified fine peat as a supporting base;
- vermicompost or sifted compost for nutrition;
- washed river sand to improve drainage properties.
The addition of garden land is allowed only if it is taken from under legumes or siderates. Soil from potato or tomato beds carries late blight spores and pathogenic nematodes that can destroy crops at an early stage.
Adjusting the acidity and moisture capacity of the soil
Tomatoes demonstrate the maximum rate of phosphorus and potassium absorption at a pH level from 6.0 to 6.5. The use of pure peat shifts the reaction to the acidic side, which causes inhibition of growth points and chlorosis of cotyledon leaves.
For deoxidation of the substrate, dolomite flour or fine chalk is used at the rate of three tablespoons per 10 liters of the mixture. The introduction of calcium-containing deoxidizers is carried out two weeks before sowing the seeds to complete the chemical neutralization reaction.
Improved moisture retention is achieved by applying agroperlite or vermiculite.:
- agroperlite loosens dense lumps and prevents caking;
- vermiculite absorbs excess water and releases it when it dries out;
- coconut fiber increases the elasticity of the soil clod.
The inclusion of baking powder in a volume of 15 to 20 percent of the total weight eliminates the formation of a hard crust on the surface of containers after watering. Oxygen flows freely to the root hairs, blocking the development of anaerobic bacteria and root rot.
Disinfection and microflora saturation
Any soil mixture collected from natural components requires strict sterilization to suppress the pathogens of blackleg and fusarium. Heat treatment in the form of calcination in an oven at a temperature of 90 degrees destroys not only pathogens, but also beneficial microorganisms.
An alternative disinfection method is to pour the substrate with a solution of fungicides or a saturated solution of potassium permanganate. The biological approach involves the use of preparations based on hay bacillus or trichoderma, which colonize the volume of soil and displace pathogenic fungi.
After aggressive disinfection, the earth must undergo a process of structuring and restoring the microbiome within seven days. The containers are covered with a film and left in a warm room, allowing beneficial bacteria to transfer mineral salts into a chelated form accessible to the tomato root system.
