Question

How can a farmer convert acidic soil?

Answer 1

Acidity has the following impacts on soil: it reduces the availability of plant nutrients like phosphorus and molybdenum, while increasing the availability of other elements to dangerous levels, especially aluminium and manganese. Below the rooting zone, essential plant nutrients can also be leached. Laterite soil is acidic in nature.

Complete answer:
Farmers utilise calcium oxide, calcium hydroxide, and calcium carbonate, all of which are alkaline or basic in nature, in agricultural fields if the soil is acidic in nature and contains more chloride or sulphate ions, to negate the effect of these ions and boost the soil's fertility.
By adding a tiny amount of quick lime or slaked lime solution to acidic soil, farmers can convert it to neutral soil.
The application of a substance containing some sort of lime to make soils less acidic is a widespread technique. The most common type of agricultural limestone is ground. The finer the limestone particles, the faster it starts to work. To modify the pH value of the soil, different soils will require varying amounts of lime.
The acid in coffee is water-soluble, therefore the acid is largely in the coffee, not the grounds. The pH of coffee grounds is comparable to that of water (between 6.5 to 6.8 pH). Coffee grounds help to improve the tilth or structure of the soil. Coffee grinds are a great source of nitrogen for composting.

Note:-
If your soil is alkaline, you can use a variety of products to lower the pH or make it more acidic. Sphagnum peat, elemental sulphur, aluminium sulphate, iron sulphate, acidifying nitrogen, and organic mulches are all examples of these. Over time, well-decomposed compost helps to reduce the pH of garden soil. By far the greatest technique to make your soil more acidic is to amend it with compost, which is high in organic matter, each season because it is done gradually and provides the most benefits for plant growth.
