| Dairy manure applications can potentially improve soil health by adding organic matter (OM) to the soil. However, intensive dairy manure applications can cause salt accumulations on arid, irrigated soils, impairing soil health, which can reduce crop growth and yield. Soil organic matter, a major contributor to soil health, increased by 0.02% for every ton of manure-derived organic matter applied. While soil OM increases typically improve soil health, salt accumulations from manure applications had antagonistic effects on soil health. As manure application rates and frequencies increased, soil properties became increasingly saline-sodic, as indicated by elevated EC and SAR values. Aggregate stability also decreased at the heaviest annual manure... |
