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.
As composting proceeds, the C:N ratio gradually decreases from 30:1to 10â15:1 for the finished product. This occurs because each time thatorganic compounds are consumed by microorganisms, two-thirds of thecarbon is lost to the atmosphere as CO 2 gas, while most of the nitrogenis recycled into new microorganisms.
