HOW TO INCREASE ACIDITY IN SOIL?
Acidic soil is mostly found in the hills or mountainous regions. This soil is composed mainly of cations like calcium ions, ferric ions, potash ions & aluminium ions. It is deficient in anions like those of nitrate ions, phosphorus ions, zinc ions etc. These soils are a good source of organic matter content like humus etc. which is good for crop production. As we know that most of the plants likely grow in the slightly acidic or neutral pH range of soil. But today the most of the soils are becoming alkaline or having pH increased due to coming of salts in the above layer of soil due to water logging or runoff of water. Soil alkalinity or salinity is also increased due to the loss of some main nutrients & minerals from the soil due to the popularity of exhaustive crop production from the agricultural land which takes away all the minerals & nutrient components from the land by means of growth & development of crop plants. These minerals & nutrients are used up in the production of dry matter & food grains from the soil. Also alkaline soil or & saline soil are not the ideal soils for the growth of the plants as these soil do not respond well to the application of water & nutrients which are added into it for helping the growth & development of plants because these soils have poor structure & physical properties due to increased concentration of anions in the soil. The several ways of increasing the acidity of soil are listed below in detail:
- By adding the manures & compost into the soil: The soil acidity is increased by adding the different organic manures & composts like vermicompost which adds the different nutrients like calcium, aluminium, nitrogen, potassium, phosphorus etc. which takes the pH of soil towards acidic reading. These will also help in producing the good crop productions from the soil where these are applied with ample crop production.
- By the addition of Sulphur in the soil: If we want to make the soil acidic in nature than we have to add sulphur in the form of sulphuric acetate or sulphuric acid so that sulphur ions are added into the soil which makes soil slightly acidic but in a long time. Also, sulphur can be added in granular form in the soil for making it acidic.
- By using synthetic fertilisers: synthetic fertilisers like Ammonium sulphate, Ammonium nitrate etc. which have a quantity of sulphur in it or sulphur coated urea are some ways of increasing soil acidity.
- Use of vinegar in the soil: the pH of garden soils is increased by the use of vinegar which makes the soil acidic in nature.
- By reducing the use of lime: As lime is used for reducing the acidity of soil so, if we reduce the use of lime chemicals & materials than the soil acidity can be increased.
- By the use of Peat moss: It is a natural way of increasing the soil acidity as it will add calcium & aluminium ions into the soil which are founded in acidic soil & hence increase the soil acidity.
