Using Precision Agriculture Field Data To Evaluate Combine Harvesting Efficiency, Justin Carroll
Using Precision Agriculture Field Data To Evaluate Combine Harvesting Efficiency, Justin Carroll
Agricultural Education, Communications and Technology Undergraduate Honors Theses
Soybean crops must be harvested during a limited time period using expensive combines and associated equipment. Maximizing combine field efficiency, the ratio of the actual harvesting capacity to theoretical harvesting capacity, is an important objective of machinery managers. Spatial and temporal yield data from a 2012 CaseIH 8120 Axial-Flow combine equipped with a 30-foot MacDon D-65 Draper header and the Case-IH Advanced Farming System (AFS) yield monitoring system were used to examine field efficiency when harvesting soybean in three Arkansas Delta irrigated soybean fields during the 2015 season. Time efficiencies (TE) in the three fields ranged from 72.9 to 85.8% …
Earthworm Populations In A Wheat-Soybean Double-Crop System Under Seven Years Of Established Residue Management Practices, Jill Elizabeth Thomason
Earthworm Populations In A Wheat-Soybean Double-Crop System Under Seven Years Of Established Residue Management Practices, Jill Elizabeth Thomason
Animal Science Undergraduate Honors Theses
Earthworms improve soil structure, distribute litter and microbes, stimulate microbial activity, facilitate decomposition, and increase nitrogen (N) availability for plant growth. Earthworm density is often reduced in low organic matter soils that are intensively managed to grow row crops. This study was designed to relate earthworm density and community composition to residue management after seven years of established management practices in a wheat (Triticum aestivum L.)-soybean (Glycine max (L.) Merr.) double-crop system maintained in Marianna, AR. Residue management practices included conventional tillage (CT) and no-tillage (NT), N fertilization to produce high and low wheat residue amounts left in the field, …
