How to determine soil acidity by weeds photo


Having noticed weeds on the plot, most of the gardeners are trying to get rid of them immediately. But the wise master will find a favor. Especially if the site is new and you do not know the composition or acidity of its soil. In this case, weeds will help. To determine the acidity of the soil by weeds is quite realistic and budget. It turns out that each weed prefers "its" soil.

On acid soils, some plants feel good, on alkaline - others. Therefore, observing the variety of weeds in the area, you can do without special methods to determine its acidity.

It is important to note that fertility, humidity, the level of groundwater, mineral composition and density of the soil are determined with the help of weeds. Ordinary weeds growing on the site are very useful plants for experienced summer residents. They serve as indicators of many parameters of your soil.

Many gardeners do not pay enough attention to determining the properties and quality characteristics of the soil. It rarely comes to the laboratory at all. But to grow a good crop without taking into account the important indicators will not succeed. After all, the health and well-being of the planted plants directly depends on the acid-base balance of the soil.

Why do ordinary gardeners need to know the methods for determining the acidity of the soil? The pH indicator is necessary to know, it signals the behavior of individual nutrients in the soil. At certain values, they simply precipitate or turn into non-digestible forms for cultivated plants.

Attention! In the soil with high acidity, a high content of manganese and aluminum. Proper development of cultivated plants in this case is very difficult.

They disrupt protein and carbohydrate metabolism, which leads to wilting of plants and the loss of a significant part of the crop. Therefore, it is necessary to take measures for alkalization, but at the same time you need to be able to properly handle the soil. Otherwise there will be more harm than good. When mineral fertilizers are added to the acidic soil (they are also acidic), you will get a very short-term effect. And then the plants will experience even greater depression. But organics for acidic soil is more useful than liming. Knowing the degree of acidity of the soil, you can accurately calculate the dose of mineral fertilizers.

It is not always possible to apply modern methods of research of the dacha soil. How to determine the acidity of the soil by weeds, many gardeners know. To do this, just look at the plants that grow well in the area without human intervention.

Herbage is influenced by other characteristics of the land, its fertility, humidity, and mineral composition. In addition, at one site in different zones, the acidity of the soil may differ significantly.

Types of weeds for the determination of soil acidity

Most often gardeners are interested in the ability to determine the acidic soil. It is on the acidic soil that many plants grow poorly. Therefore, a good harvest or lush flowering does not have to wait.

If there is acidic soil on the plot, how can we determine it by weeds, the photos of which can be found in any reference book? What weeds tell you that your site has a soil with high acidity? Let's start with the names and photos of the most common herbs.

On very acidic soils the field chamomile grows,

blueberries, blueberries,

Erica, sorrel sour, white-faced, mariyannik meadow.

On the soil with an average acidity grows Baltic sphagnum,

oxalacea mint

lingonberry, rosemary marsh,

ear, oxalis.

Weak soil can be recognized by the presence of sedge (hairy and early),

dogrose male, breezy oakwood and buttercup,

forestry, bluebell and broadleaid bellflower, creeping couch grass,



Sorrel loves sour soil, tricolor violet, horsetail,


Highlander Grungy. You need to know that separately or very rarely growing weeds are not considered indicators. Only the predominance of these plants on the site can be called a signal of the degree of acidity of the earth.

Alkaline soil is replete with bindweeds and poppies.

Useful recommendations

Many cultures have good adaptability to pH fluctuations. Therefore, in different sources you can find the opposite information about the weeds-indicators. Moreover, very rarely cultures are full adherents of the same type of soil. But if you do not take into account his “tastes” at all, you can even destroy a useful plant. Why? In the soil with a high level of acidity, nitrogen nutrition is disturbed and a sufficient amount of magnesium, calcium and phosphorus do not flow to the plant. But there are toxic compounds in it. Another destructive factor for cultivated species is the rapid development of pathogens in an acidic environment.

How to reduce the level of acidity of the soil in the area without negative consequences

Dilute it with natural materials. Dilute the soil with lime, dolomite flour, chalk, lime flour. Wood ash works well. Its effect is much softer, but no less effective.

Important! A single action is not able to change the acid composition of the soil for a long time.

Therefore, deoxidation is carried out annually and regularly. As soon as you notice problems with the growth and development of plants, immediately check the level of acidity.

To an experienced gardener, everything goes to help. Therefore, look at the plants on your site. They can tell you a lot of useful things.
