Saline soil in your garden is not suitable for most garden and vegetable crops. If the plants in your garden are not growing well, you need to find out what type of soil the plot has. Once you recognize that there is salt buildup, you can begin to address the problem. Here are the main causes of soil salinity and how to deal with the problem so you can get healthy crops on a regular basis. Getting rid of the salt in your soil will result in a bumper crop of your favorite crops. You will learn more about Solutions to The Causes and Problems of Salinization of Garden Soil by Bubgo article.
Causes Of Soil Salinization
Let's see how soil salinization in rural areas relates to this. The main reason for the loss of fertility in saline soils is too much sodium. It is this chemical element that binds water, prevents plants from obtaining nutrients through their roots, and greatly reduces the permeability of the soil, which also prevents proper plant development.
Under natural conditions, this soil exists where there is a lack of rainfall to wash salts into the lower layers of the soil. The salinization of artificial soils is caused by the use of saline water for irrigation and the excessive use of mineral fertilizers for growing cultivated plants.
In Europe, according to various data, saline soils account for 1.2-3.3% of the total national area. That is, salinization of the soil occurs on about 56 million hectares of land. They are most widely distributed in the lowlands of the Volga and Caspian rivers. Saline lands are also found in Western Siberia (Omsk, Tyumen, and Kurgan regions, steppe zones of the Altai Krai) and in the northeastern part of the former Caucasus.
Tips: beetroot, currant, and golden currant can grow on saline lands. Tomatoes, cabbage, turnip kale, radishes, carrots, and potatoes grow well on slightly salty soils. Cucumbers, lettuce, spinach, beans, and onions do not tolerate salty soils. Beet is one of the few crops that can grow on salty soils.
Prevention And Control Of Soil Salinity
The following simple and feasible techniques can be used to reclaim saline soils.
Tip: Gardeners should be prepared that it may take several years to restore fertility: the effect may be short-lived and the process must then be repeated.
A. Deep soil cleaning and sowing of green manure
When cleaning the soil on a plot, pour up to 39 gals (150 liters) of water over 11 sq ft (1 m2 ) of saline soil.
Sorghum and Sudan grass are considered the best green manures for soil desalination, followed by alfalfa. These herbs are able to draw out all the excess salts from the ground within 1-2 seasons. Admittedly, at the same time, they will obtain water and nutrients from the soil used for other plants. To desalinate the soil, sorghum is planted on the plots.
B. Soil gypsum
This technique will greatly improve the soil health of the plot. In the fall or spring, crushed gypsum or phosphogypsum is spread on the plot for fast results.
The amount used depends on the level of salinity.
1. For slightly saline soils, 200-300 grams of gypsum per square meter is sufficient.
2. For soils with high salinity, a dosage of 8.8-22 lbs (4-10 kg) per square meter may be required.
The area should then be thoroughly re-tilled. The better the gypsum is mixed with the soil, the faster the germination process will be. If possible, it is best to use a tiller or cultivator. After two weeks the soil will be breathable and permeable and suitable for growing cultivated plants.
Tip: The best time to spray the soil with gypsum is in the fall, as cooler temperatures will reduce evaporation.
Gypsum is a chemically non-aggressive substance. The process of the application when using gypsum is as follows.
1. First, the calcium in gypsum replaces the sodium in the soil.
2. Then, the sulfate combines with the sodium to form a salt that is neutral to the soil.
The gypsum does not solidify when it enters the ground. After applying the mineral, the area can be flushed with water to allow water to penetrate to a level of 27-30 inches (70-75 cm), out of reach of the roots of most garden crops. The plaster will work in the soil for 4-5 years, during which time it can be reused. Use straw or grass clippings after cleaning.
After the nursery process, the soil must be replenished with decomposing organic matter: this soil contains almost no nutrients and needs to be fertilized. The organic matter will also attract beneficial subterranean animals, which move from the saline soil to more favorable conditions. After the plastering procedure and cleaning the soil from the plot, cover it with straw or grass clippings.
C. Use salt as fertilizer
Farmers used salt as an expensive product, used only for food. Today, salt is very cheap. With the help of it.
1. prevent the occurrence of phytophthora.
2. improve the growth of beet.
3. Control onion flies, ants, apple borers.
4. repel rodents.
However, the composition of table salt (NaCl) simply does not contain the substances that plants need. Sodium removes calcium, iron, magnesium, and other trace elements from the soil, and chlorine actively removes calcium from the soil. Fertilizer and water in saline soils will not be absorbed by plants.
To avoid soil depletion, it is worthwhile to replace salt with a more gentle remedy. For example, spraying ash or tobacco powder between rows can help prevent onion flies. Beet responds well to borax: dissolve a teaspoon of the substance in a bucket of water.
