Definition - What does Tensile Strength mean? Tensile strength is the ability of a material to withstand a pulling (tensile) force. It is customarily measured in units of force per cross-sectional area. This is an important concept in engineering, especially in the fields of material science, mechanical engineering and structural engineering.
Microorganisms In A Compost Pile. Microorganisms such as bacteria, fungi, and actinomycetes account for most of the decomposition that takes place in a pile. They are considered chemical decomposers, because they change the chemistry of organic wastes.
Essentials of Composting. To prepare compost, organic material, microorganisms, air, water and a small amount of nitrogenare needed. Microorganisms such as fungi and bacteria break down the organic material. A small amount of garden soil or compost can provide sufficient microorganisms.ompost can be used to: 1  enrich the soil by adding a natural source of nutrients. 2  loosen tight, heavy soils. 3  help sandy soils retain moisture and nutrients. 4  add to potting soils for container grown plants. 5  mulch around landscape plants.
