A) Lime is very helpful in maintaining the water content in the soil
B) Lime decreases the acidity of soil
C) Lime decreases the basicity of soil
D) High concentration of lime is necessary for the plant growth.
Correct Answer: B
Solution :[b] Lime is any substance with the capability of neutralizing soil acidity. Most soils contain appreciable amounts of acidic components (hydrogen H+ and aluminium \[Al+++)\] that can be toxic to plants. Indeed, lime is the "anti-acid" for soils. No soil amendment provides as many benefits as lime. Lime raises soil pH, providing a more favourable environment for microorganisms. Dolomitic lime provides the major portion of calcium and magnesium required for plant growth. Furthermore, plants utilize applied fertilizers more efficiently on soils that are properly limed.
