With increasing fertilizer and fuel costs, producers are increasingly keen to improve on-farm nutrient cycling through biologically intensive methods. Currently, poor plant-soil-microbe interactions do not support healthy nutrient flow, which limits crop yield and favors fertilizer-dependent farming. Slow residue breakdown also inhibits direct seeding adoption and adherence since heavy residue at seeding time impedes direct […]

Improving the sustainability of agriculture requires a wide range of research from the basic to the applied, from molecular to whole organism, and from field to system level. In-field studies are irreplaceable for gaining knowledge of best practices, varieties, rotations, crop mixtures, and other factors that will make real differences in agricultural productivity and environmental […]

The online agricultural carbon calculator, OFoot, provides a user-friendly interface suitable for not just researchers, but also producers and students, to estimate whole farm carbon footprints. OFoot continues to be a key component to many research, extension, and educational efforts. New planned projects require the tool to be stable, easily maintained, and have good performance. […]

Dryland wheat-fallow producers have begun switching to a direct seed tillage system for soil health benefits such as reduced runoff, increased water infiltration, increased consistency of crop stands, more and longer period of surface cover from crop residue, better soil moisture, and fewer dust clouds at planting time. However, this practice often requires increased pesticide […]

Grazing cattle may be managed in such a way to improve the productive capacity and/or health of the land that supports them. This study assessed and continues to assess the soil health and productivity of a certified organic ranch pasture under a variety of grazing and fertility treatments. Two different strategies of planned grazing management […]

This project explores acid-tolerant rhizobia that could sustain nitrogen fixation and pulse yields as Washington soils acidify.

Researchers piloted a farm-level sustainability assessment to understand challenges, guide improvements, and support resilient regional food systems in Clark County.
