Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are benefits of addling lime.
A
Cost-effective, as less fertiliser may need to be used once pH is at correct level.
B
Improves availability of nutrients
C
Improves soil structure
D
Kills grass grub.
Explanation: 

Detailed explanation-1: -Lime is a soil conditioner and controls the soil acidity by neutralising the effects of acids from nitrogen (N) fertiliser, slurry and high rainfall. Other benefits include an increase in earthworm activity, improvement in soil structure and grass is more palatable to livestock.

Detailed explanation-2: -The use of lime to nuetralize soil acidity will also add calcium and magnesium to the soil solution. This addition can correct low nutrient availability of these two nutrients and also change soil structure.

Detailed explanation-3: -The addition of lime to garden soil can increase the alkalinity of acidic soil and add plant nutrients and minerals, creating a healthy lawn and a healthier base for plants to grow. Agricultural lime and dolomitic lime are two types of lime commonly used in lawns and gardens.

Detailed explanation-4: -Agricultural lime helps lower the soil’s acidity levels by rendering it more pH neutral. By applying lime to the soil when it becomes too acidic, farmers can ensure they are helping improve their crop output. If crops can’t properly grow, they can’t produce, which impacts the agriculture business and its bottom line.

Detailed explanation-5: -Liming improves soil pH, Ca, and Mg contents and reduces Al concentrations in the soil solution. In addition, liming improves beneficial microbe populations in the soil. Furthermore, liming improves P concentration in the soil solution by reducing P immobilization by Fe and Al in acid soils (Fageria and Baligar, 2008).
