Let’s talk about the sand — a simple and useful material in the country business. More precisely, the main aspects of its application. Sand-is crushed and ground water particles of rocks. With the right approach, it can significantly improve the physiological properties of the soil. How? Will talk detail.
Excellent property of sand to accumulate and keep warm successfully use in country business, adding it to heavy soils, especially in clay and loamy. Clay perfectly absorbs water, and when drying is compressed, forming a heavy layer covered with cracks, which is very poorly tolerated by many plants. And the sand successfully eliminates this problem, providing a clay soil with good drainage.
The properties of sand
Sand differs by types there are river, quarry, quartz and so on. I will not go deep into the properties of each, as for the needs of the is usually used river sand. In soils saturated with river sand, the roots of our green Pets feel more than at ease, densely branched and grow freely. In sandstones well rooted cuttings of plants, and when transplanting their tender roots are not damaged.
Sand contributes to the preservation of moisture in the soil, is often used as a mulching material, oddly enough it sounds. And all because in the hot summer days, even under a thin layer of sand, the soil remains moist, so there is no danger of drying the roots on the sandstones with irregular watering.
What grows well on sandy soils
On sandy and sandy loam soils take root well unpretentious plants: centaurea, irises, poppies and others. Feel great in sandy soils and representatives of the legume family, on the roots of which has its own bacterial environment, it is friendly to perceive the sand. Respect sandy soil and many berry bushes: currant, honeysuckle, gooseberry, BlackBerry and others. These shrubs have a highly branched root system, which perfectly strengthens the porous sandy soil.
All kinds of coniferous trees and shrubs, many fruit and berry crops are perfectly adapted to sandy-clay soils. Also on soils with a high content of sand perfectly grow Alpine plants: campanula, saxifraga, leontopodium and others, melons and grapes. Moreover, grapes growing on sandy and sandy loam soils, practically does not suffer from phylloxera (difficult to remove species of aphids).
Sand and fertilizers
Sandy soils are porous and saturated with oxygen, so the absorption of mineral and organic fertilizing plants is very fast and with maximum efficiency. Unfortunately, the sand is not able to retain nutrients in the soil, because the grains of sand cannot absorb nutrients, so in sandy soils often add clay. If you are preparing a soil mixture for plants, the clay content should be at least 30%.
Made in the sandy soil of mineral and organic fertilizers is enough to feed the plants only for a year. Fertilize should be in early spring and only manure and peat are introduced in the autumn. Fertilizers should be added with great care: due to the porous structure of the sandy soil, they immediately penetrate to the root system and can “burn” the roots of plants. The best fertilizer that significantly improves the physiological properties of sandy soils is compost with the addition of peat, manure (2:1:1) and mineral fertilizers.
In addition, in sandy soils should be made annually wood ash: it slightly deoxidizes acidic soil, and acts as a source of neutral potassium, phosphorus and other useful plant minerals. Ash is introduced into the soil in the ratio: 200 g per 1 sq.m of soil. Just do not make rash with nitrogen fertilizer, otherwise it will lose its useful properties: the interval between the introduction of nitrogen-containing fertilizers and ash should be at least a month. Ash cannot dig to the ground, but simply evenly sprinkle under the plants: rain and meltwater will deliver it to the desired depth.
Soil mixtures containing sand
Sand is used as a drainage material. It is useful to add it to almost every soil mixture. Let’s consider three main types of such mixtures:
- heavy consists of turf land, humus and sand (3:1: 1);
- the average includes in composition sod land, humus and sand (2: 2: 1);
- light consists of earth, humus or turf and sand (1:3:1).
Young plants with a weak root system need light, well-drained sandy soils, and bulbous, powerful trees and shrubs need heavier soil.
Vulnerability of sandy soils
If you have sandy and sandy loam soils on your site, you should know that they are easily eroded, and the beds are deformed under the influence of natural factors. Therefore, place the beds across the slopes, in time to fall asleep ravines formed after showers, leave some of the weeds in the aisles (which do not interfere with the growth of your green Pets, of course).
If possible, add clay and humus to sandy soils. Keep in mind that the soil saturated with sand, strongly subsides, so when planting seedlings do not forget to tie them to the pegs. Forming the beds, dig the ground to a depth of 0.4-0.5 m, tamp the bottom of the beds with clay at 10-15 cm (you can lay the old linoleum or put boards), and then fill up the excavated land back. So you avoid possible deformation of the beds.
