PPT-SOILS What is soil? It is not just, “dirt”

Soil Defined formed from the weathering of rocks and organic activity and is composed of loose rock fragments and clay derived from weathered rock mixed with organic material Soil is primarily made up of broken down rock minerals and organic materials . Physical . weather reduces the particle size of rocks and in doing so prepare the material for chemical weathering. The rate of all chemical reactions involving solids is determined by the amount of exposed surface area. These four drawing illustrates sequentially dividing particles into smaller particles.

An . agricultural.  definition of soil is "a dynamic natural body on the surface of the earth in which plants grow, composed of mineral and organic materials and living forms". Extensively developed in Antarctica and rare outside of Polar regions. Characterized by a specific lithology due to penguin nesting behavior. Includes a combination of soil, pebbles, guano, highly rich in organic. Soils differ from one part of the world to another, even from one part of a backyard to another. . They differ because of where and how they formed. And over time, five major factors control how a soil forms. These factors are .

Soils support the growth of higher plants by providing a medium for plant roots and supplying nutrient elements that are essential to the entire plant.. Soil properties are the principal factor controlling the fate of water in the hydrologic system. Water loss, utilization, contamination and purification are all affected by the soil.. KEEPING. . SOILS. . FIT. . Most soils have a large supply of nutrients. But when soils are continually used for growing food, nutrients are removed when the crop is harvested. . That is why farmers must add nutrients to their soils.
