Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws
School of Natural Resources: Dissertations, Theses, and Student Research
Marginal cropland is suboptimal due to historically low and variable productivity and limiting biophysical characteristics. To support future agricultural management and policy decisions in Nebraska, U.S.A, it is important to understand where cropland is marginal for its two most economically important crops: corn (Zea mays) and soybean (Glycine max). As corn and soybean are frequently planted in a crop rotation, it is important to consider if there is a relationship with cropland marginality. Based on the current literature, there exists a need for a flexible yet robust methodology for identifying marginal land at different scales, which …
Beneficial Effect Of Injected Air Into Subsurface Drip Irrigation (Sdi) On Plant Growth Using Runoff From A Feedlot, D Dissanayake
Beneficial Effect Of Injected Air Into Subsurface Drip Irrigation (Sdi) On Plant Growth Using Runoff From A Feedlot, D Dissanayake
School of Natural Resources: Dissertations, Theses, and Student Research
Due to water scarcity and increasing food demand, nonconventional water sources (e.g., human and animal wastewater) represent a valuable alternative to traditional water resources for agricultural use. Among these alternatives, treated animal wastewater, particularly feedlot runoff may represent a valuable solution in states like Nebraska due to its abundance. Subsurface drip irrigation (SDI) is a low-pressure micro-irrigation system that delivers water to the crop root zone through buried drip tapes with embedded emitters at fixed intervals. Despite multiple advantages (great water application uniformity, high water use efficiency, and improve fertilizer application), SDI can lead to poor aeration in the rhizosphere …
