Have you ever thought, “how much water am I saving by starting a rotational grazing plan?” “Can cover cropping increase water retention in my soil, by exactly how much, and is it worthwhile?”
These and other questions seeking to quantify the amount of water that can be saved are what the latest peer-reviewed report from the Soil Health Institute aims to answer.
This report introduces a new method to quantify the impacts of soil organic carbon changes on water storage capacity. Previous methods showed varying levels of impact, but this new equation helps researchers and producers accurately and easily measure how much water is being saved.
This aids in quantifying the benefits of various soil management practices that increase soil organic carbon, helps calculate how much money is being saved, and models the effect of management changes on drought resilience.
