In a greenhouse, a special microclimate is formed both in the air and in the soil. Considering that from year to year, summer residents plant the same plants in greenhouses, it is necessary to take care of the fertility of the soil.
This must be done in such a way as not to harm the beneficial soil microflora, but how?
Fertilizers for greenhouses
Before you sprinkle and pour the remains of last year's fertilizers into the soil, think about what you are going to grow. If it is nightshade, then they have a special appetite for potassium, nitrogen, phosphorus, calcium, iron, and also magnesium, zinc and boron.
If you add each element separately, you will not be able to do without complex calculations and in the end you can get confused. It is easier to buy complex organomineral additives or biofertilizers.
Biohumus
All greenhouse crops respond to organic matter, of which spring ones include humus, compost, vermicompost or biohumus. This is a product of processing manure and plant residues by earthworms and soil microorganisms.
Of all organic matter, this is the most effective fertilizer, which not only saturates the soil with nutrients, but also improves the structure, does not contain pathogens, pest larvae or weed seeds.
If you use biohumus regularly, the need for mineral additives is significantly reduced. And overdosing on biohumus is impossible.
If you need to deoxidize the soil, then of all the means, it is best to add dolomite flour to the greenhouse.
By following these recommendations, you can not worry about the level of biologically active fertilizers in the soil and get a rich harvest every year, without the need for regular soil replacement.
