Soil functions are general soil capabilities that are important for many areas of life including agriculture, environmental management, nature protection, landscape architecture and urban applications. Six key soil functions are: Food and other biomass production. Environmental Interaction: storage, filtering, and transformation.

Soil chemists research concerns about organic and inorganic soil contamination, pesticides and other pollutants, and environmental health risks.
Soil chemistry is the branch of soil science that deals with the chemical composition, chemical properties, and chemical reactions of soils. Soils are heterogeneous mixturesof air, water, inorganic and organic solids, and microorganisms (both plant and animal in nature). No two soils are exactly alike.
Deep connection with Earth Sciences. Soil Science and Soil Ecology is obviously is very related and integrated with Earth Sciences – Geology, Geography, Geophysics.Interesting study process.Diverse career options.Helping humanity.It affects the ability of soil to hold essential nutrients. It influences soil structure, nutrient availability as well as soil PH. The availability of nutrients in the soil and their uptake by plants is also affected by CEC e.g., soils with low CEC develop potassium and magnesium deficiency.
Traditional soil chemistry (soil fertility) focuses on chemical and biochemical reactionsin soils that influence nutrient availability for plant growth, and potential environmental consequences associated with inorganic and organic fertilization, especially with nitrogen and phosphorus.
What to Use to Improve Chemical Properties Organic matter may be added to the soil by the use of peat moss, sawdust, compost, animal manures, and similar materials. The added organic matter must undergo decomposition to humus before it will affect exchange capacity, buffer capacityand leaching.
Soil chemistry is defined as the field of soil science that deals with the chemical constituents, properties, and reactions of soils. Soil chemistry plays a central role in food production and the protection of human health.
The five factors are: 1) parent material, 2) relief or topography, 3) organisms (including humans), 4) climate, and 5) time.
Healthy soils are essential for healthy plant growth, human nutrition, and water filtration. Healthy soil supports a landscape that is more resilient to the impacts of drought, flood, or fire. Soil helps to regulate the Earth’s climate and stores more carbon than all of the world’s forests combined.
Soil provides plants with foothold for their roots and holds the necessary nutrientsfor plants to grow; it filters the rainwater and regulates the discharge of excess rainwater, preventing flooding; it is capable of storing large amounts of organic carbon; it buffers against pollutants, thus protecting groundwater …
November 9, 2023. Soil science is the study of soil, a complex natural system that plays a vital role in agriculture, environmental protection, and human health. Soil is a mixture of minerals, organic matter, air, and water that supports plant growth and provides habitat for a wide range of organisms. Soil scientists study all aspects of soil ...

Nov 8, 2024 · Soil is the biologically active and porous medium that has developed in the uppermost layer of Earth’s crust. It serves as the reservoir of water and nutrients and a medium for the filtration and breakdown of injurious wastes. It also helps in the cycling of carbon and other elements through the global ecosystem.
