Interactions Between Biochar And Compost In Organic Winter Wheat Production And Soil Quality Under Dryland Conditions, Phearen Kit Miller
Interactions Between Biochar And Compost In Organic Winter Wheat Production And Soil Quality Under Dryland Conditions, Phearen Kit Miller
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Organic wheat grown under dryland conditions encounters challenges such as limited nutrients and water. Maintaining organic wheat production requires solutions to these problems in order to retain economic sustainability for the farmers.
Research on biochar and compost have been conducted globally. Despite well known benefits of compost on soil and crop production, few organic farmers apply compost to their fields. Research on biochar is still new. Biochar is charcoal created from pyrolyzing agricultural material under conditions of low oxygen and high heat. Many studies claim that biochar is a valuable soil amendment for improving organic production and reducing environmental pollution …

Soil structure and aggregate stability (AS) are critical soil properties affecting water infiltration, root growth, and resistance to soil and wind erosion. Changes in AS may be early indicators of soil degradation, pointing to low organic matter (OM) content, reduced biological activity, or poor nutrient cycling. Hence, efficient and reliable AS measurement techniques are essential for detection, management, and remediation of degraded soil resources. Here we quantify soil AS by developing a novel proximal sensing technique based on shortwave infrared (SWIR) reflectance measurements. The novel approach is similar to the well-documented high energy moisture characteristic (HEMC) method, which yields a …
Novel Treatments For Native Forb Restoration In The Great Basin, Adam J. Fund
Novel Treatments For Native Forb Restoration In The Great Basin, Adam J. Fund
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Public land management agencies, conservation organizations, and landowners are interested in expanding the diversity of plant species used in rangeland restoration seedings. While the restoration of native grasses and shrubs in the Great Basin has become increasingly successful, restoration of native forbs continues to be problematic. In the Great Basin, soil water availability and soil fungal pathogens are thought to limit to restoration success. During the course of two years, we conducted two field experiments at three sites in the Great Basin that spanned a latitudinal gradient encompassing different precipitation and temperature patterns.
In the first experiment, we evaluated two …
Effect Of Wood Chips As A Component Of Soilless Media On Growth And Nutrition Of Food And Ornamental Crops, Kristen Bullough
Effect Of Wood Chips As A Component Of Soilless Media On Growth And Nutrition Of Food And Ornamental Crops, Kristen Bullough
Undergraduate Honors Capstone Projects
Peat is the central component of the soil-less media mix in all greenhouse crop production but it is expensive because it is harvested in Canada and shipped to greenhouses across North America. Wood chips provide a local, low-cost alternative to peat, but observations by growers indicate potential growth reductions from the addition of wood to peat-based media. Here I report the effects of the addition of wood chips to peat-based media. The study included four treatments: two controls (peat/vermiculite: 50/50 and 75/25) and two treatments with wood chips ' (peat/wood chips: 50/50 and 75/25) with three species (sunflowers, soybeans, and …
Stormwater Management And Ecosystem Services: A Review, Liana Prudencio, Sarah E. Null
Stormwater Management And Ecosystem Services: A Review, Liana Prudencio, Sarah E. Null
Watershed Sciences Faculty Publications
Researchers and water managers have turned to green stormwater infrastructure, such as bioswales, retention basins, wetlands, rain gardens, and urban green spaces to reduce flooding, augment surface water supplies, recharge groundwater, and improve water quality. It is increasingly clear that green stormwater infrastructure not only controls stormwater volume and timing, but also promotes ecosystem services, which are the benefits that ecosystems provide to humans. Yet there has been little synthesis focused on understanding how green stormwater management affects ecosystem services. The objectives of this paper are to review and synthesize published literature on ecosystem services and green stormwater infrastructure and …
Community-Level Plant–Soil Feedbacks Explain Landscape Distribution Of Native And Non-Native Plants, Andrew Kulmatiski
Community-Level Plant–Soil Feedbacks Explain Landscape Distribution Of Native And Non-Native Plants, Andrew Kulmatiski
Wildland Resources Faculty Publications
Plant–soil feedbacks (PSFs) have gained attention for their potential role in explaining plant growth and invasion. While promising, most PSF research has measured plant monoculture growth on different soils in short-term, greenhouse experiments. Here, five soil types were conditioned by growing one native species, three non-native species, or a mixed plant community in different plots in a common-garden experiment. After 4 years, plants were removed and one native and one non-native plant community were planted into replicate plots of each soil type. After three additional years, the percentage cover of each of the three target species in each community was …
