Question

List any two drawbacks of acid soil.

Answer 1

Soil acidity can lead to elemental toxicities for plants by aluminum, iron, manganese, and zinc due to the increased solubility of these elements at low pH values.

Soil acidity can cause limited availability of some macronutrients and micronutrients such as phosphorus which binds to iron and aluminum oxides in acidic soils.

Other elements in their plant-available forms, such as molybdate, exibit decreased solubilities at low pH values.

Microbial activity drops off in acidic conditions which can lower nitrogen (the key plant nutrient) concentrations, reducing nitrogen fixation and nitrogen mineralization, two processes vital to creating plant-available forms of nitrogen.

Organic matter decomposition by soil organisms slows.

Calcium, magnesium, and potassium deficiencies develop.

Answer 2

Acid soil: A natural process caused by agriculture where the concentration of hydrogen ions in the soil increases due to inefficient use of nitrogen is called as soil acidifiacation.

Drawbacks:

• The plants has preferred range of soil acidity and if that is out of that range, the plant suffers from a variety of diseases or dies.
• Less productivity.
• Make soil less fertile.
