Soils are Alive!
Soil Biological Fertility Soils are alive! A variety of soil organisms live in the soil. These include bacteria, fungi, microarthropods, nematodes, earthworms and insects. These organisms live on soil organic matter or other soil organisms and perform a number of vital processes in soil. Other organisms are involved in transformation of inorganic molecules. Very few soil organisms are pests. The role of soil organisms in soil fertility may involve the following: helping soil to form from original parent rock material, contributing to the aggregation of soil particles, enhancing cycling of nutrients, transforming nutrients from one form to another, assisting plants to obtain nutrients from soil, degrading toxic substances in soil, causing disease in plants, minimizing disease in plants, assisting or hindering water penetration into soil
Soil Chemical Fertility Which elements are essential for plant health and which may be toxic to plants? Soil chemistry is concerned with the availability of elements for plant uptake as well as the presence in soil of elements and chemical compounds that might be present at levels that are detrimental to plants and soil organisms.

Soil Physical Fertility How do soil physical properties affect water movement and nutrient uptake through the plant roots? Physical properties and processes of soil affect soil fertility by altering water movement through soil, root penetration of soil and waterlogging
What are soil organisms, how do they help soil fertility?
Soil Chemical Fertility Soil chemistry is concerned with the availability of elements for plant uptake as well as the presence in soil of elements and chemical compounds that might be present at levels that are detrimental to plants and soil organisms. Some elements in the soil are nutrients and are essential for plant growth. Other elements are not essential and may be toxic to plants. The availability of elements for plant uptake is affected by soil pH and reactions of the elements with soil particles and organic matter. Soil chemical fertility is affected by: composition and parent material of the soil, soil pH, element adsorption to clay surfaces and organic matter, soil salinity.
What is soil physical fertility? Physical properties and processes of soil affect soil fertility by altering water movement through soil, root penetration of soil and waterlogging. Important physical properties that affect fertility include soil structure and texture. Structure is the amount of aggregation and pores in soil and texture is the proportion of clay and sand particles in soil. Both affect soil fertility by affecting water movement through soil, root penetration and water logging. Erosion is an important physical process that decreases soil fertility. When soil structure and texture are unfavourable for water movement through soil water erosion and waterlogging may be increased. Soil salinity is a chemical property but can affect soil physical fertility by decreasing the movement of water through the soil. Physical soil characteristics important to soil physical fertility include: soil structure, soil texture, water repellence. Physical processes related to soil physical fertility include: aggregation, water infiltration, waterlogging, soil erosion
