The same crops are grown in the greenhouse every year, because of this the soil becomes poor over time, and the harvest is not pleasing in terms of volume and quality.
A few useful tips will help improve the quality of the soil so that you can reap a large harvest every year.
The most accessible method is to add fertilizers such as rotted manure or peat.
This can be done in March, if the weather permits, or before planting, add a complex mineral fertilizer - azophoska or nitroammophoska at the rate of 50 g per 1 m² and thoroughly dig up the soil.
In March, when the weather is still unstable, the greenhouse is not ready for sowing cucumber, tomato or pepper seeds.
However, at this time you can start growing greens, early vegetables, and radishes in it.
After the soil in the greenhouse has warmed up and the soil is moistened, you can move on to the next stage: starting biological processes in the soil.
To improve the soil, ready-made preparations such as "Baikal" are used.
The entire area of the greenhouse is treated with the solution, and a positive temperature must be maintained for 7 days after the microorganisms are introduced into the soil.
This trick will allow the plants to germinate much faster and will speed up the ripening process several times.
