How to normalize the acidity of the soil – determine the pH of the suburban soil
Advise how to normalize soil acidity? We have a dacha, we used it mainly for summer holidays, there was no free time for the garden. When they retired, they decided to become gardeners and planted most of the plot with vegetables. Harvested in the spring and were very surprised. If carrots and tomatoes pleased with the abundance, then onions and beets we can say that there were none. In a conversation with a neighbor, she complained about her problem, so she said that the majority of the village has acidic soil, so not everything will give birth. What to do, are there any ways to reduce this indicator?
If, with the same care, horticultural crops give you a different harvest, you should think about whether the acidity in your area is increased. In case of confirmation of the “diagnosis”, it is necessary to take urgent measures and choose ways to neutralize the acidity of the soil. The fact is that very few plants “like” the increased indices, while the majority require neutral acidity. And some vegetables and even flowers even prefer slightly acidic soil. All this should be taken into account so that your work is not wasted. After all, what will grow directly depends on the structure, composition and acidity of the soil..
Before you go in search of drugs, determine what kind of acidity indicator in your area. This can be done by purchasing special test strips or an apparatus called an acid meter. Soil analysis will also be done in an agrochemical laboratory, but it will cost even more. But there is an easier way – watch what plants grow in the country, and you can establish acidity at no cost.
Plants – indicators of acidity
Acidity is the ratio of acid to alkali in the soil, which is referred to as pH and can range from 0 to 14. Depending on which element is larger, there are 3 types of soil:
- Slightly acidic (pH greater than 7). Such weed soil is preferred by wheatgrass, nettle, burdock, clover. Chrysanthemums, chamomiles and roses also grow well on it. Vegetables will delight the harvest with cucumbers, peas, potatoes, radishes and zucchini.
- Neutral (pH = 7). The middle ground is preferred by most plants, especially vegetables. Among them beets, garlic, cabbage, onions.
- Sour (PH below 7). The most accurate indicator is the presence of horse sorrel in the garden. Moss, horsetail, plantain, wild mint are also fond of sour soil. But the leader in low rates are garden plants such as rhododendron and blueberry. Vegetable crops grow well parsley, pumpkin, tomatoes, carrots and, of course, sorrel.
How to neutralize soil acidity
Neutral indicators do not need to be adjusted. You need to intervene when they are above or below pH 7.
Sour soil needs deoxidation, and this can be done by adding alkalizing agents to the site, for example:
- wood ash;
- calcium nitrate;
- ground limestone;
- lake lime;
- bone meal;
- dolomite flour.
If, on the contrary, you need to increase the acidity, add special acidifying preparations (superphosphate, ammonium sulfate) to the weakly acidic soil. Humus also works well, where bark was added. And mulch the trunk circle of acid-loving shrubs and trees or aisles on vegetables with coniferous litter.
