Effluent was applied through the sprinkler system at different growth stages up to tasseling. However, there are other methods that can be used to apply liquid manure, such as injecting or knifing under the soil surface. S Timing of application is another consideration. To minimize leaching potential when there is no growing crop, effluent was applied in early spring and during the growing season. Water Management S Calibration of the system needs to be done prior to applying effluent, whether applied through sprinkler or injecting.
Irrigation scheduling is very critical to minimize any potential leaching.
We used weather information from a local weather station in Yuma County to estimate daily crop water use, and we also monitored soil moisture once a week. Training Training is a key factor in proper animal waste management. This was accomplished through workshops, field tours, and on-site training for local producers and individuals who deal with animal manure management. The training should emphasize the proper management of liquid or solid manure from point of production, storage, and field application. The above best management practices are very important in managing any source of nitrogen to minimize nitrate leaching to water resources.
