Answer
The four functions of soil in crop production include:
Soil Air Movement: Soil facilitates the movement of air, which is crucial for the survival of plant roots and soil organisms.
Soil Water Infiltration: It allows for the infiltration of water, ensuring that plants have access to the moisture they need to grow.
Storage of Water: Soil acts as a reservoir that stores water, making it available to plants during dry periods.
Nutrient Provider: Soil provides essential nutrients required for plant growth and development.

Answer
Contour ploughing helps prevent soil erosion by following the natural contours of the land. This technique minimizes runoff and allows water to soak into the soil rather than flowing over the surface, which reduces soil erosion potential.
Step 3
Discuss how contour ploughing can be used to channel surface water into dams.

Answer
Contour ploughing involves creating ridges or furrows along the contour lines of the land. This practice allows for the effective channeling of surface water by directing it into specific waterways and holding it on the fields, which assists in reducing soil erosion and supports water accumulation for storage in dams.

Answer
Contour ploughing involves ploughing along the contours of the land to reduce water runoff while maintaining the slope's natural shape. In contrast, terracing involves reshaping the land into flat levels or steps to create flat surfaces on a slope, which helps in managing water overflow and prevents soil erosion.

Answer
Greyish clay soil has moderate drainage capabilities due to its fine texture, which may lead to slower water infiltration. However, its capacity to retain moisture is beneficial for crops, although excessive water can lead to temporary waterlogging.
Step 6
Explain the pH scale and what it means if the pH is 7,8.

Answer
The pH scale ranges from 0 to 14 and indicates the acidity or alkalinity of a substance. A pH of 7 indicates neutrality, while a pH of 7.8 suggests that the soil is slightly alkaline which can be beneficial for certain crops, as it indicates a balanced nutrient availability.
Step 7
Name the substance that must be added to the soil to improve the pH.

Answer
To improve the pH of the soil, one can add gypsum or agricultural lime (calcium carbonate) which helps in reducing acidity and balancing the soil's pH.

Answer
The young farmer should consider:
Reducing Tillage: Implementing no-till or reduced-till farming practices to minimize soil disruption and improve soil structure.
Cover Crops: Planting cover crops during the off-season to enhance soil fertility and reduce erosion.
Organic Matter: Adding organic matter such as compost to improve soil health, moisture retention, and nutrient availability.

Answer
Fair labour practices ensure that workers are not overburdened and can perform their tasks effectively. When workers feel valued and are working in safe conditions, they are more likely to efficiently determine optimal locations for buildings and facilities, enhancing productivity and sustainability.

Answer
The different types of capital in a farming venture include:
Fixed Capital: e.g., buildings and dams
Working Capital: e.g., livestock, implements, equipment
Financial Capital: e.g., cash reserves for operations
Human Capital: e.g., skills and labor of the workers.

Answer
A suitable camp for animal production requires:
Adequate Water Supply: Clean and fresh drinking water must be available.
Forage Accessibility: The camp should have enough palatable fodder for grazing animals.
Proper Topography: The landscape should support efficient movement of the animals and include adequate grazing areas.
