Solid Manure Application: Toward a Sophisticated Spreader
Hanna, H. Mark
Two generations of low-cost chemical fertilizer and the differentiation of crop from livestock farming have given manure a bad name, even among farmers. With increasing awareness and concern about the air and water impacts of improper manure management, it is imperative that both crop and livestock farmers once again consider manure as a resource rather than a waste (Fleming et al., 1998). To fully realize these benefits will require some changes in farming systems, technologies, and practices, and regulation is likely to be an even larger factor driving these changes than it is today. But unless these strategies generate on-farm benefits and address the farmer's fundamental constraints, they are unlikely to be widely adopted or conscientiously implemented.
