Compost can be a valuable source of organic matter for farmers. It can improve the soil’s ability to absorb and store water as well as hold plant nutrients. Applied at heavy rates, compost can also contribute nutrients and salts to the soil.
When using large volumes of compost, we recommend testing it in a lab first. These tests can help you to make informed decisions about nutrient management and avoid salinity issues. If buying in bulk from a composting facility, growers should ask the seller for a compost analysis report.
It can be difficult to understand how the numbers in your compost report from a laboratory should inform management decisions. Our team developed a new webpage to help growers navigate these reports. Check out the page here.
