Farmers are requested to mix lime with soil while farming their fields...
Explanation:

Introduction:
Lime is commonly used in farming practices to improve the quality of soil. It is a type of soil amendment that helps in altering the pH level of the soil. The pH level of the soil plays a crucial role in determining its fertility and the availability of nutrients to plants.

Acidity and Basicity of Soil:
Soil can be acidic, neutral, or alkaline (basic) based on its pH level. The pH scale ranges from 0 to 14, with 7 being neutral. A pH level below 7 indicates acidity, while a pH level above 7 indicates alkalinity.

Importance of pH level in soil:
The pH level of the soil affects the solubility and availability of nutrients for plant growth. Different plants have different pH requirements for optimal growth. Most plants prefer a slightly acidic to neutral pH level (around 6 to 7), as this range allows for better nutrient availability.

Effect of acidity on soil:
Acidic soil can have a detrimental effect on plant growth. It reduces the availability of essential nutrients like nitrogen, phosphorus, and potassium. Additionally, it can lead to the accumulation of toxic elements like aluminum and manganese, which can harm plant roots. Acidic soil also affects microbial activity, reducing the breakdown of organic matter and nutrient cycling.

Role of lime in soil:
Lime is commonly used to neutralize acidic soils. When lime is added to the soil, it reacts with the acidic components, such as hydrogen ions (H+), and raises the pH level. This process is known as liming or soil sweetening.

Benefits of adding lime to soil:
Adding lime to soil offers several benefits:

1. Decreases soil acidity: Lime helps in raising the pH level of acidic soil, making it more neutral or slightly alkaline. This makes the soil more suitable for plant growth and improves nutrient availability.

2. Enhances nutrient availability: By neutralizing acidity, lime helps in unlocking nutrients in the soil, making them more available for plant uptake. This promotes better nutrient absorption and overall plant health.

3. Improves soil structure: Lime aids in the formation of stable soil aggregates, improving soil structure and reducing compaction. This allows for better water infiltration and root penetration.

4. Enhances microbial activity: Lime provides a favorable environment for beneficial soil microorganisms, which play a crucial role in nutrient cycling and organic matter decomposition.

5. Prevents nutrient deficiencies: Lime application can prevent nutrient deficiencies by ensuring that essential nutrients are readily available to plants.

Conclusion:
In conclusion, farmers are requested to mix lime with soil while farming their fields primarily because it decreases the acidity of the soil. By raising the pH level, lime improves nutrient availability, enhances soil structure, and promotes overall plant health.

Farmers are requested to mix lime with soil while farming their fields...
Farmers are advised to mix lime with soil while farming their fields because it increases the pH of acidic soil (the higher the pH the less acidic the soil); in other words, soil acidity is reduced and alkalinity increased.
