How to determine the acidity of the soil?
Some gardeners do not attach much importance to the acidity of the soil in their garden, and in vain: knowing these features, you can understand which plants will develop without much hassle, and which ones will have to tinker. In addition, a well-known indicator of acidity helps to find the right tools and methods for processing a suburban area. At the same time, it is not worthwhile to delve too deeply into the topic of soil diversity — there will be enough general concepts for successful gardening.
What is the composition of the soil?
The mechanical structure of the earth is one of the most important indicators, which is very easy to define. According to this indicator, the soils are divided into:
- heavy - as a rule, these are clayey species;
- moderate - these include loam;
- lungs. These varieties include sandy and sandy soil.
Independent species often include gravel or rocky variations, but such types can be found relatively rarely.
To determine the mechanical composition, you need to take a little bit of soil, slightly moisten it and roll it in the form of clay sausage 3-4 mm thick.The resulting product should be scrolled in the form of a ring and evaluate how it was possible:
- if the soil rolls off without difficulty, it is plastic to the touch, easily retains its shape and coagulates freely - in the area clayey earth;
- if the sausage roll turned out, but when you try to create a ring, the product is cracked - in the area of loam;
- if any attempts to create something from the soil fail because of its friability, there is light soil in the garden.
These varieties are divided in turn into several subspecies, but for a general understanding of the question, it is enough to know only the indicated soil classifications. Each of these items has both advantages and disadvantages, but one thing is certain: a good harvest can be grown on any of the listed options.
The indicator of the mechanical composition determines the density, breathability, moisture content, as well as permeability. In addition, different species require a different approach, because they are saturated with different elements.
Soil features and acidification dependence
Soil reaction is an important indicator that can be tested at home.Experts identified several groups of plantations, which depend on the degree of acidification of the soil:
- Plants that require slightly alkaline or neutral ground. These include zucchini and pumpkin, beets, cabbage and onions, legumes (peas with beans), trees - plums or cherries, as well as currants and some flowers - carnations, tulips or asters;
- Plantations requiring a neutral or weakly acid reaction. These include cucumbers and lettuce, apples and pears, as well as roses, begonias, etc .;
- Vegetation, which is particularly comfortable in subacid soils - tomatoes, radishes, as well as corn and potatoes, thujas, gooseberries, irises, lilies, etc .;
- Trees and plants that grow in acidic lands. These are pine and sorrel, heathers and lily of the valley, cranberries, lingonberries, and rhododendrons.
It should be said that not all of the plantations listed are typical representatives of calcephil or calcephobic - many of them often adapt to existing growing conditions. However, unrecorded requirements that are necessary for plants can further affect the development of diseases or starvation of a plant.
Determination of soil reaction
The simplest method of determining acidity is the delivery of a test material for laboratory analysis. But such methods are not always appropriate and not often everyone can afford it, especially since the methods at hand are no worse:
- Using indicator paper, it is quite quick and simple to check the indicator: you need to dig a hole (at least 35 cm in length) and collect soil from its vertical walls, preferably 3-4 times and in different places. The material must be mixed with distilled water and squeezed in a fist with litmus paper. If the earth is acidic, the color of the paper will vary from red to yellow, if it is alkaline, it becomes greenish or blue.
- By well-developed plants. If the soil is acidified, mint, violets, plantain, sorrel, etc. will feel great on it. With a weak acidification grows wild rose, chamomile, wheat grass, as well as sow thistles. Alkaline varieties attract poppies and bindweed.
And how to check the level of acidity, if at hand were only folk remedies? There are several ways:
- On the glass, previously placed on a dark (better black) surface, you need to pour a little material and sprinkle it with table vinegar.If active release of foam has begun - the soil in the garden is alkaline, a moderate reaction occurs in neutral varieties, and foam cannot form in an acidic soil;
- According to the shade of beet leaves. If the beet that grows on your site has a red shade of foliage - it means that the earth is acidic.
Studying the level of acidity in many ways helps gardeners to study their site and the requirements for plants, because unsuitable plantings often die for no apparent reason.
Simple methods of exploring a sample of the earth will help you understand how to adjust the nutrition and care of plants, helping them ensure maximum comfort.
