Land resources of general economic importance are not only fertile. This group also includes soils that contain a lot of mineral salts. These substances cause great harm to plants. Therefore, such soils are difficult to use for growing crops. To cope with the problem, it is worth using special plants for saline soils. They are able to grow and develop in conditions of high concentrations of soil solution.
Problems of saline soils and their landscaping
Soil salinity is considered a very serious problem, which complicates landscaping and causes great problems in choosing plants.To identify the accumulation of salt in the soil, special studies are required.
This violation occurs when the soil is located near the sea or ocean. It is also caused by the use of water with a high content of minerals.
The accumulation of salt provokes damage to the root system, impaired plant growth, and loss of their decorative properties. However, this does not apply to all cultures. There are crops that are not too demanding on the composition of the soil and can withstand its salinity.
When choosing crops, you should give preference to shrubs and trees. They can be used for hedges and protective plantings, placed along the perimeter of the site. At the same time, it is herbaceous plants that help cope with the salinity of the beds.
When planting herbaceous perennials in saline areas, it is recommended to remember about timely care. At the same time, in the spring it is important to remove dried and damaged plant fragments in a timely manner. Rejuvenation and replanting of plantings and the use of organic mulch are of great importance. Spring watering helps to avoid new salt deposits, and summer watering helps maintain the attractiveness of greenery.
Effective perennials for saline areas
Saline soils, or saline soils, are considered a fairly common problem.To regulate the salt content in them, you can use different methods. One of the most affordable options is bioreclamation. It involves crop rotation of salt-tolerant crops with halophyte plants that can develop in conditions of high salt concentrations.
Halophytes are plants that have a desalinizing effect, shade the soil and prevent moisture loss. In addition, they prevent the movement of salts from the lower soil horizons to the upper ones.
The most promising halophytes include:
- sweda;
- Gerard's rush;
- potassium solyanka;
- quinoa;
- licorice;
- Climacoptera is fleshy.
After only 2-3 years, halophytes growing in saline soils can be gradually combined with forage plants. In this case, it is recommended to use companion crops that are characterized by increased salt tolerance. Barley, millet, and sorghum are suitable for this. Wheat, beets, and sunflowers have the same properties.
Methods to combat the problem
To cope with the problem, you should follow the following rules:
- reduce the use of salts;
- deal with excess snow in time;
- instead of the usual salts, use safe substances - sand or potassium chloride;
- use wind protection if the site is located on the coast.
Soil salinity is considered a real problem, which creates difficulties in growing crops. To cope with the violation, you need to use special methods.
