Soil profile: The soil profile provides information about the texture, structure, mineral content, nutrient content, and layers of soil. It reveals the different horizons and their characteristics, helping to understand soil composition and suitability for plant growth.
Mineral content: Minerals from soil are processed by plants to become usable nutrients for animals and humans. These minerals are essential components that influence soil fertility and plant health.
Nutrient content: The nutrients present in soil, derived from mineral content, are vital for plant development. They support growth and productivity, impacting agricultural outcomes.
Soil composition: Soil composition includes the mixture of mineral particles, organic matter, water, and air within the soil profile. It determines soil texture and structure, affecting its ability to retain nutrients and support plant life.
Soil erosion: Soil erosion negatively impacts farming by removing the topsoil layer, which is rich in nutrients and organic matter. This reduction in topsoil decreases soil fertility and hampers crop production.
