To investigate the potential of biological and organic matter inputs to increase soil water storage, target long-term yield increases and soil improvement
Management practices influence microbial activity by altering carbon availability and conditions reflecting rapid changes in the biological function of the soil, although the reserach is still in the preliminary stages this has been highlighted where increased microbial biomass and nutrient availability was associated with plots receiving high amounts of organic matter.
