Garden soil surprise you with its diversity. They come in loose, dense, sandy, clayey, rich, poor organics… One characterized by a high transmission ability of water. There is land for good holding her. Every owner of the plot at least needs to know the acidity of his soil. Acidic and alkaline soils differ not only in chemical composition but also on the possibilities of growing their own specific cultures.
The weeds are widespread. At each site they are different. Many of them, like crop plants, need certain conditions. So the abundance of clover, sundew rotundifolia suggests that the soil lacks nitrogen. Quinoa, chickweed average, acrid Buttercup, elderberry indicate the high content of nitrogen mustard — phosphorus. The soil is rich in calcium, if it produces sunflower, lady’s slipper. Belous protruding, ferns, heathers, violet dog indicate a low content of calcium. On soils with a high carbonate content of sea buckthorn is growing. But unkempt and too dense a soil is a perfect place for mother-and-stepmother ordinary and Wheatgrass.
Fertile soil is «habitat» sniti ordinary, nettle, creeping Buttercup, plantain, dandelion… If among these plants, the main weight falls on the plantain, then you are dealing with dry soil.

Alkaline soil «draws» poppy, slumber white, ivacko, elm rough. Interesting fact – on alkaline soil growing pulmonaria with violet flowers on acid — pink.
If the site you notice the dandelions and buttercups, consequently, the soil is heavy and clay, too wet. Most often, this soil occurs on long time don’t recycle the plot. This soil is poor in oxygen. Therefore, when planting at this site the soil is dug, lay a drainage layer and planting pits in the ground is replaced by a loose and fertile. Although this area is well suited for some decorative plants (iris, Japanese…).
On light, acidic and depleted soils dominated by thickets of sorrel and wild violets. Such soils are well adapted acid-loving culture such as ropes, rhododendrons.
Individually growing plants naturally cannot serve as a reliable indicator of soil type. But at the same time, and they are useful. In particular, they can indicate the optimal location for a particular plant. With Spry would be appropriate Phlox paniculata. Horsetail will indicate the rationality of Siberian irises. Earth nettle is suitable for bobovnik, the ground – he said.
