Question

Lime is added to soil which is
A. Sandy
B. Alkaline
C. Acidic
D. Salty

Answer 1

Hint:The primary role of lime is to alter soil pH and balance soil acidity which can improve the availability of plant nutrients. Soil is a substance consisting of five ingredients:- minerals, organic soil, living organisms, gas, and water.

Complete answer:
Soil minerals are classified into 3 classes of size- clay, silt and sand. Soil texture is defined as the percent of particles in these classes of size. The terrestrial mineralogy is various.Quartz is the most frequent mineral in soils; it makes beautiful, but not quite reactive, crystals. Soils are organic material in different decomposition states: plants, livestock and microbial residue. The percentage of organic soils is among the best indicators of agricultural soil quality. The colour of soil varies from brown, yellow, red, grey, white and black to the colours of the uncommon soil, including green and blue.
Lime is an alternation of soil made from ground limestone rock that contains magnesium carbonate and calcium carbonate naturally. Adding lime to the soil increases the pH level of soil and makes them more alkaline and less acidic. Though lime includes magnesium and calcium that are important nutrients for healthy growth of plants, it is not a substitute for fertilizer. The primary role of lime is to alter soil pH and balance soil acidity which can improve the availability of plant nutrients.

Thus, the correct answer is option C. i.e., Acidic.

Note:When low soil pH begins to inhibit the supply of nutrients, limes are added. Lime restores equilibrium in excessively acidic soil, which returns pH to an optimal level of growth.
