Do Soil Amendments Improve Crop Production And Poor Water Infiltration?, Matt Yost, Megan Baker, Tejinder Singh, Grant Cardon

All Current Publications

Soil amendments are widely promoted as tools to improve aggregation, porosity, water holding capacity, nutrient availability, and water infiltration of soils. These benefits are possible, but they depend on the specific soil problem being treated, amendment type and rate, soil chemistry, soil texture and structure, and the time since application. Studies at Utah State University provide a useful short-term test of what growers can reasonably expect from a single surface application of these amendments.

Part Ii: Sustainable Irrigation Practices For Cut Flowers, Chloe Seeborg, Melanie Stock, Burdette Barker, Alex Rodriguez, Jonathan D. Meyer

All Current Publications

Sustainable irrigation uses crop and environmental information to guide the frequency (how often) and amount (how much) of water to apply. Without this balance, poor irrigation practices can result, causing crop stress from too little or too much water, nutrient loss and contamination, or wasted water that drains below the root zone. This fact sheet covers the basics of soil water storage, crop water demand, considerations for designating irrigation zones, using free weather stations, and water conservation strategies for gardens and small farms, with a focus on cut flowers.

Agrivoltaics: Combining Food And Solar Power On Agricultural Lands, Dharla Soteros, Kendall Becker, Spencer J. Good, Ngoni Mufute, Matt Yost, Logan Mitchell, Scott Hotaling

All Current Publications

Utah’s ranchers and farmers face pressure to sell land to developers, conserve water, and manage increasing production costs (Li et al., 2019). One way producers can keep growing food while diversifying and increasing revenue is by integrating agriculture and solar electricity generation on the same land, a practice known as agrivoltaics. In this fact sheet, the authors describe agrivoltaic setup options, summarize agrivoltaics' impacts on livestock and crop production, and discuss implementation economics.

Educating Livestock Producers And Monitoring The Ecological Health Of Grazing Spaces, Morgan Mathisonslee, Matt R. Raven, Crista Derry

Journal of Extension

Addressing the climate catastrophe requires a systems approach with a focus on regenerating agricultural landscapes. To address these complex problems, we offered a monitoring training focused on a systems approach to livestock stewardship using the Savory Institute's Ecological Outcomes Verification protocol to monitor ecosystem health. The training encouraged producers to use systems-based management practices to promote ecological regeneration. We found that despite producers not adopting the monitoring protocol, there were increases in the ecological health of their farms. We suggest Extension professionals consider teaching similar ecological monitoring protocols to benefit producers and support claims about regenerative agriculture.

Strengthening The Philippines' Agri-Fishery Rde System: A Case Study Of A Public Coordinating Agency As A Bridging Organization, Cynthia Remedios V. De Guia, Luis Rey I. Velasco, Maria Faina L. Diola

Journal of Public Affairs and Development

The Philippine agricultural research, development, and extension (RDE) system has long struggled to live up to its ideals. Decades after the passage of the Agriculture and Fishery Modernization Act (AFMA), the RDE system was reported to have failed to innovate, largely because it failed to translate research into development outcomes. This has resulted from persistent gaps in knowledge exchange, institutional linkages, and collaboration among system actors. In fragmented systems, meaningful interaction and trust seldom emerge spontaneously, making bridging mechanisms necessary. Bridging organizations (BOs) play this role by connecting multiple and diverse actors, mediating relationships, enabling knowledge flows, and enhancing capacities …
