Demonstration and calibration of Haney test as Soil Health Nutrient Tool for assessing nutrient pools in Louisiana rice agroecosystems

The Haney test has been adopted as Soil Health Nutrient Tool in NRCS programs. However, its adequacy is not known in anaerobic production systems due to the fact that the test was originally developed for upland soils. Currently there is no study and demonstration available as to how well the Haney test works in assessing different nutrient pools in flooded rice agroecosystems. The lack of this knowledge could result in economic loss for farmers and negatively affect the environment. This project will assess the adequacy of Haney test with the goal to calibrate the Haney test as Soil Health Nutrient Tool for rice production in Louisiana.
