Soil aggregation can physically protect organic carbon from decay by soil microbes. [19] More aggregate formation can result in more soil carbon storage. There is much evidence that arbuscular mycorrhizal fungi increase soil aggregate formation, and that aggregate formation may be mediated by the arbuscular mycorrhizal protein glomalin. [20]
Soil characteristics that have been altered by addition of polymers include compressive strength, volume stability, hydraulic durability, and conductivity. [5] Polymers can help prevent soil erosion and increase infiltration of water by strengthening soil aggregates and supporting soil structure. The properties of the soil itself are a dominant ...
Glomalin is hypothesized to improve soil aggregate stability and decrease soil erosion. [5] However, since glomalin can not be adequate quantified in soil, studies usually analyze the GRSPs extract, which is a complex mixture including proteins and other substances. [4]
Soil sieve nests with dry soil aggregates after removal from a laboratory drying oven. Soil aggregate stability is a measure of the ability of soil aggregates—soil particles that bind together—to resist breaking apart when exposed to external forces such as water erosion and wind erosion, shrinking and swelling processes, and tillage.
Soil stabilization is a general term for any physical, chemical, mechanical, biological, or combined method of changing a natural soil to meet an engineering purpose. [1] Improvements include increasing the weight-bearing capabilities, tensile strength, and overall performance of unstable subsoils , sands, and waste materials in order to ...

In microbial communities like soil, the C:N ratio is a key indicator as it describes a balance between energetic foods (represented by carbon) and material to build protein with (represented by nitrogen). An optimal C:N ratio of around 24:1 provides for higher microbial activity. [16] [17]
Your protein requirements change as you age. Here’s why protein is essential for senior athletes for recovery and to maintain muscle mass.
