Database Research Summaries2018 Development of a New Soil Quality/Health System
The focus of this project is to develop a database that could facilitate wide adoption by both research and commercial laboratories.
- Determine sensitivity of selected soil enzyme activities to detect diverse land management impacts on soils within major soil types of soybean agro ecosystems in Ohio.
- Across diverse land management systems determine key chemical, physical and microbial properties of soils to confirm that soil enzyme index is consistent with these other measures of soil quality.
- Calibrate an interpretable soil enzyme activity pedotransfer function that is sensitive to anthropogenic disturbance, independent of soil type.
- Develop a numerical index that correlates with soybean yield based on a combined hydrolytic soil enzyme assay that detects soil management and an oxidation assay that controls for drainage.
- As of March 26, 2019, information is being collected from participating farmers and exchanging information concerning soil health and soybean productivity. Information will be uploaded as soon as it becomes available.
- Our research provides a scientifically validated soil enzyme index test that is ready for testing at the farm scale – to determine its ability to independently to detect soil management similar to traditional nutrient soil tests and be highly correlated to soybean yields in farmers’ fields.
