Explanation

• Saline-sodic and sodic soils have excess sodium, which harms soil structure and crop growth.
• These soils require chemical amendments to replace sodium with calcium.
• Gypsum, sulfur, and sulfuric acid are commonly used for reclamation.

Additional information:

Amendments used for sodic soil reclamation:

• Gypsum – supplies calcium directly
• Sulfur – converts into sulfuric acid in soil
• Sulfuric acid – reacts with calcium carbonate
• Pyrite – slow-release sulfur source
• Organic matter – improves soil structure

Explanation

• Gypsum (CaSO₄·2H₂O) is widely used to reclaim sodic and saline soils.
• It replaces sodium ions with calcium ions in the soil, improving structure.
• Helps in reducing soil alkalinity and increasing crop productivity.

Additional information:

Other Soil Amendments (4 examples):

1. Lime (CaCO₃) – for acidic soils
2. Sulphur – lowers soil pH
3. Organic manure – improves fertility
4. Compost – enhances soil structure

Explanation

• Cotton is an important fiber crop in Pakistan.
• Seed rate depends on seed type and germination percentage.
• Delinted seeds with 75% germination require lower seed rate to ensure proper plant population.

Additional information:

• Delinted seeds are cleaned to remove lint, improving germination.
• For fuzzy seeds (with lint), the seed rate is slightly higher: 8–10 kg/acre.

Explanation

• Nitrobacter bacteria convert nitrite (NO₂⁻) into nitrate (NO₃⁻) in the soil.
• This is the second step of the nitrification process, which is important for plant nutrition.
• Nitrite is toxic to plants, but nitrate is easily absorbed as a nutrient.
