No matter how the economic situation in the country changes, the fashion for own gardens and orchards remains unchanged. As before, millions of people from spring to late autumn are worried about how to grow a good harvest. Greenhouses make a significant contribution to this business. They make it possible to provide the family with early fresh herbs, and allow growing tomatoes, cucumbers and other heat-loving crops in the northern regions.
However, these "helpers" also require proper handling, they may have problems. Many gardeners and summer residents are faced with such a phenomenon as a change in the composition of the soil. Then the question arises of why the earth turns green in the greenhouse. What can contribute to this?
The land in a greenhouse turns green for several reasons. There are four of them: waterlogging, acidification, an excess of fertilizers and insufficient ventilation. This leads to the appearance of algae or moss, it is these plants that give the soil a green color. Let us consider in detail these factors and ways to eliminate them.
The first reason why the earth turns green in a greenhouse is a large amount of moisture. It happens earlyspring and cool weather. Summer residents forget that the greenhouse is a closed space, the evaporation of moisture is slower if the temperature"overboard" is not very high. Dealing with this problem is easy. Can apply
mulching the soil, and watering often will no longer be necessary. For this, traditional mulch is used in the form of hay, straw and sawdust. Or you can take non-woven, covering materials, they are even more profitable, weeds grow less under them.
The second reason why the earth turns green in a greenhouse is the increase in soil acidity. To find out the level of this indicator, you need to conduct a small experiment. A plastic bottle with a volume of 0.5 liters is taken. Slightly warm water is poured there, a few tablespoons of earth are poured. A rubber medical fingertip is put on top. Shake the bottle well. If the fingertip is puffed up - the soil is acidic, if it is not completely straightened out - slightly acidic, it remains hanging - the pH is normal. In case of increased acidity, quicklime or chalk must be added to the soil. But ash should not be taken for these purposes, since it will take a lot of it, and this can lead to other problems.
The third reason why the earth turns green in a greenhouse is the presence of a large amount of fertilizer. This is the case when "we wanted the best, but it turned out as always." There is only one advice: carefully observe agricultural technology. Well, if this has already happened, then it is worth planting crops that require a lot of fertilizer. For example eggplant.
Fourththe reason why the earth turns green in the greenhouse is the lack of ventilation. Here we must remember that your country house should have a door, a window (on the contrary, on the sides, and it will also not interfere on the roof). This distribution will regulate air flow, and will also provide free access to insects, and they are necessary for successful pollination.
Another general piece of advice. In the greenhouse, as elsewhere, it is necessary to observe crop rotation, this will help to avoid many problems and will increase the yield.
