It is impossible to imagine that it will be possible to get a good harvest on unfavorable soil. The reasons for the deterioration of the soil can be very diverse, so if you have reason to believe that there is a problem, you should immediately look for the reasons. In this article, I'll show you how to identify imperfections in soil and enrich it.
1. Slow plant development, superficial root growth without deepening
These are obvious signs of heavy soil requiring dilution.
2. Stagnant water
If the water does not go deep for a long time, it interferes with the access of oxygen to the roots, causing the development of fungi. In this case, drainage is needed to allow excess drainage. Air circulation is improved by perlite, straw, compost, sand, husk and other similar materials.
3. Nutrient Deficiency
By the appearance of the plant, mineral starvation is always noticeable (for example, the color of the leaves changes, growth slows down). Depending on the type of plant, you yourself can determine the lack of a particular substance by referring to the reference book.
4. Soil depletion
From year to year it is necessary to enrich the soil by introducing a fresh layer from a mixture of sand, earth and compost.
5. Increased or decreased acidity
It is not difficult to regulate acidity. Increasing substances: peat, sawdust. Lowering: chalk, limestone, dolomite flour. Sulfates of magnesium, potassium and ammonium nitrate neutralize the alkaline reaction.
6. Excess salt
The salts are washed out with plain water. Hose the soil thoroughly several times.
7. Soil fatigue
If one crop is planted in the same place from year to year, it takes the elements it needs from the soil, thereby depleting it. Other, "superfluous" elements accumulate. Therefore, it is recommended to rotate cultures. For example, plant nightshades instead of cucumbers.
8. Poisoning the soil with herbicides
Where can they come from in the greenhouse? On the straw from grain crops there are often residues of pesticides, as well as on peat - it is often treated for weeds.
9. Accumulations in hazardous concentrations of minerals
Illiterate or overzealous fertilization can poison the soil. So, for example, when using potassium salt (and this is chloride) to replenish the garden with potassium, chlorine will accumulate in the soil, because the plants do not need so much of it. Or sulfur may build up due to the frequent use of sulfates. Excess ammonia, nitrates causes fresh manure. In cases of an overdose with minerals, the soil is renewed or washed with existing water, and the top dressing is replaced with another one, without excess substance.
It is very important to monitor the condition of the soil in the greenhouse and on the site. Plant diseases and poor yields are primarily caused by the condition of the soil.
