This chapter seeks to frame manure management strategies and practices to minimize P losses to water, with a focus on manure properties, land application, farmstead infrastructure, farming systems. Although many options exist to better manage manure, and, more specifically, P in manure, doing so requires comprehensive approaches that consider factors far beyond the direct handling of manure and require decisions that may compete or conflict with other priorities, most notably profits and time management.}, keywords = {estuarine waterbodies, farmstead infrastructure, in-field stacking, managing animal manure, manure application rate, manure phosphorus losses, phosphorus pollution}, doi = {10.2134/asaspecpub67.c12}, url = {files/bibliography/20-039.pdf}, author = {Peter J.

Agriculture in the United States must respond to escalating\ demands for productivity and efficiency, as well as pressures to
improve its stewardship of natural resources. Growing global\ population and changing diets, combined with a greater societal
awareness of agriculture{\textquoteright}s role in delivering ecosystem services\ beyond food, feed, fiber, and energy production, require a
comprehensive perspective on where and how US agriculture\ can be sustainably intensified, that is, made more productive
without exacerbating local and off-site environmental concerns.\ The USDA{\textquoteright}s Long-Term Agroecosystem Research (LTAR) network
is composed of 18 locations distributed across the contiguous\ United States working together to integrate national and local
agricultural priorities and advance the sustainable intensification\ of US agriculture. We explore here the concept of sustainable
intensification as a framework for defining strategies to enhance\ production, environmental, and rural prosperity outcomes from\ agricultural systems. We also elucidate the diversity of factors\ that have shaped the past and present conditions of cropland,\ rangeland, and pastureland agroecosystems represented by the\ LTAR network and identify priorities for research in the areas of\ production, resource conservation and environmental quality,\ and rural prosperity. Ultimately, integrated long-term research\ on sustainable intensification at the national scale is critical to\ developing practices and programs that can anticipate and\ address challenges before they become crises.
