Effects of polyacrylamide and organic matter on microbes
Effects of polyacrylamide and organic matter on microbes associated to soil aggregation of Norfolk loamy sand
This cost is due to loss of soil organic matter (SOM), CO 2 emissions, on-farm costs (fertilizers, manure, etc.), clean-up operations, and accidents such as flooding . Additionally, loss of fertile topsoil reduces water quality, plant available nutrients, crop yields, and soil quality due to soil degradation [1] , [2] .

Polyacrylamide (PAM) has been reported to increase aggregation and improve soil physical properties in loamy sand soils, but nothing is known about the effects of PAM on microbes involved in
Effects of biochar and polyacrylamide on decomposition
Purpose. Various soil conditioners, such as biochar (BC) and anionic polyacrylamide (PAM), improve soil fertility and susceptibility to erosion, and may alter microbial accessibility and decomposition of soil organic matter (SOM) and plant residues. To date, no attempts have been made to study the effects of BC in combination with PAM on the decomposition of soil SOM and plant residues.

Effects of Different Organic Manures on the Biochemical
Despite of the improving effects of organic manures, differences in organic matter composition and thus substrate availability are likely to be the reason for the differences in microbial community structure. The NPK+M and NPK+S treatments increased the PLFA biomarkers for bacteria, gram-positive and gram-negative bacteria.
