What is Soil? Soils perform vital functions to sustain plant and animal life, regulate water flow, filter and buffer pollutants, cycle nutrients, and provide physical stability and sort. This definition is from the Soil Science Society of America.
Nov 18, 2023 · Organic matter improves soil structure, which results in increased water infiltration following rains and increased water-holding capacity of the soil; it also enhances root growth into more permeable soil.
It is the fraction of soil consisting of plant and animal residues in different stages of decomposition that is rich in carbon and nitrogen (phosphorus, sulfur, and trace minerals). Soils can have from a trance to up to 20-30% organic matter.
When organic materials, such as residues (leaves and roots) or organic amendments (manures and composts), are added to the soil, they provide a source of active organic matter, which is consumed by soil organisms for metabolism and growth.
Soil organic matter is the key to building and maintaining healthy soils because it has such great positive influences on essentially all soil properties—aggregation, nutrient availability, soil tilth and water availability, biological diversity and so on— helping to grow healthier plants.

May 12, 2020 · The layer that contains soil, where soil-forming processes happen, is called the pedosphere. Soil is made of minerals, water, air, and broken down organic material. This organic material can be things like leaves, roots, twigs, and bugs.
