Study Notes

Definition of Key Terms

Soil: Loose surface material composed of inorganic particles and organic matter, crucial for plant support, water and nutrient supply.
Farming: The practice of cultivating crops or raising animals, contributing to food production and economic strength through trade.
Construction of Structures: Refers to the methods and styles of building, involving both complete structures like buildings and components like arches.
Waste Disposal: Process of collecting, processing, recycling, or depositing waste materials, which is categorized by source and composition.

Properties of Soil

Soil functions as a vital natural resource, supporting life with distinct physical and chemical properties.
Key properties include:
- Soil Texture: Proportion of sand, silt, and clay in the mineral fraction, with 12 defined textural classes for effective management.
- Soil Structure: Arrangement of soil particles into small aggregates (peds), aiding in soil health.
- Soil Fertility: The capacity to sustain plant growth, enhanced by fertilizers and nuclear techniques, important for high yields and quality plants.

Soil Conservation and Protection

Soil degradation from climate change highlights the need for conservation practices and awareness.
Effective sustainable management methods include:
- Tree Planting: Roots stabilize soil and prevent erosion; vegetative cover shields soil from wind erosion.
- Terrace Building: Creates leveled sections on hilly terrain to reduce water runoff; dry stonewalling is a method for construction.
- No Till Farming: Reduces soil disruption, maintains water retention, and decreases fossil fuel dependence while promoting soil health.
- Contour Plowing: Plowing across slope contour lines slows water runoff, protecting soil integrity.
- Crop Rotation: Alternating crops to balance nutrient demands and combat soil pathogens, improving soil structure and fertility.
- Maintain Soil pH: Monitoring pH is crucial as it impacts nutrient availability; acidic soils hinder nutrient absorption by plants.
- Water the Soil: Regular watering conserves soil and limits erosion caused by wind.
- Salinity Management: Addressing salt accumulation to protect crop health and mitigate erosion.
- Promote Helpful Soil Organisms: Encouraging soil bacteria, fungi, and earthworms to enhance soil health and aeration.
- Grow Indigenous Crops: Native plants support soil conservation and reduce erosion risks.

Soil pH Levels

Acidic Soil: pH < 7, high levels of aluminum and other metals hinder nutrient absorption.
Neutral Soil: Optimal for most plants, balanced nutrient availability.
Alkaline Soil: pH > 7, reduces availability of essential nutrients, affecting plant growth.
