This publication discusses management practices that increase crop nitrogen utilization. It also includes an interactive worksheet for calculating available nutrients supplied by manure application. The worksheet can be ...
This publication provides estimates of crop removal of nitrogen, phosphorus and potassium for forage crops grown on dairies in western Oregon. It also provides guidance on liquid manure application rates to meet crop nitrogen requirements.
Publications and documents demonstrating the art of Mud and Manure Management for the pastures and forage crop. These contain useful information that are important when managing and producing livestock on pasture.
This collection has information on soil testing and ferilizing, renovation. forage management , hay, irrigation, feeding values, forage types, forage anti-quality factors, leasing pastures and more.
Because of our typically wet springs in western Oregon, the average hay crop usually ends up being of low quality. However, when forage in the field is young and tender it is of high quality. As the forage matures, it ...
Drought conditions have drastically reduced hay yields in the last year or two. With dry conditions forecast to continue, livestock producers need to rethink strategies for conserving forage.
By selecting the right forages and using efficient management practices with limited irrigation or drought conditions, producers can achieve reasonable forage production with reduced input costs. This publication from the University of Nebraska highlights irrigation and crop options, water-use efficiency of different forages, and more.
