Potential for site specific management of Lolium rigidum (annual ryegrass) in Southern Australia.
… distribution is no exception. The potential for site specific management of annual ryegrass was assessed to increase farmers’ financial returns through reduced herbicide costs while maintaining weed control in commercial paddocks near Bute and Tarlee, SA. Commercially available sensors N-Sensor, …

Arthropod damage in corn across site-specific management zones and differing water and nitrogen levels
Site-specific insect management has the potential to make pest management more efficient, but has yet to be implemented. One method of implementing site-specific management would be to make decisions at the management zone level. Management zones are homogenous subregions within a field that can be …

Improving Nitrogen Management in Corn- Wheat-Soybean Rotations Using Site Specific Management in Eastern Virginia
… in the United States. Recent developments in site-specific management (SSM) technology have the potential to reduce both N overapplication and underapplication and increase farmers' net returns. In Virginia, due to the high variability of within-field yield-limiting factors such as soil …

Determination and Manipulation of Leaf Area Index to Facilitate Site-Specific Management of Double-Crop Soybean in the Mid-Atlantic, U.S.A.
… selection, and other cultural practices. Site-specific management strategies such as varying plant population may be used to manipulate LAI and increase yield in leaf area-limited systems. Furthermore, methods to remotely sense leaf area are in order to facilitate such management …

Effects of Corn (Zea mays L.) Stover Removal and Leaching on Soil Test and Whole Plant K Levels in Corn and K Fertilization/High-Input Treatments on Soybean Using Site-Specific Management to Increase Soybean (Glycine max) Production in South Dakota
… not economically sufficient, a wide degree of site-specific variability existed between sampling periods and points, site locations, and season. Nitrogen (N) fertilization has the potential to increase soybean grain yield. Onfarm cooperators applied nitrogen fertilizer in the encapsulated urea …

Variability Structure Estimation: The Role of Sample Support
… variability in soil properties is a prerequisite to many activities, such as site specific management (i.e., precision farming), groundwater and solute transport modeling, groundwater pollution assessment and remediation, etc. Due to soil heterogeneity, statistical measures are often used for …

Adoption of best management practices in the Louisiana dairy industry
… are encouraged to voluntarily implement site specific management practices known as best management practices (BMPs) to reduce the delivery and transport of agriculturally derived pollutants such as sediment, nutrients, pesticides, salt and pathogens to surface and ground waters. …

Impact of human disturbance on coastal birds: population consequences derived from behavioural responses
… including body mass, environmental conditions, site quality, and disturbance type. The energetic and lost-feeding-opportunity costs of responding to individual disturbance events were relatively small and therefore considered unlikely to cause major reductions in individual body condition or …

A comparative study on the fish species composition, diversity and catch rates among the fisheries reserves on the Zambezi and Kwando rivers, Zambezi region
… This baseline study evaluated fish assemblages, specifically species composition, diversity, and catch per unit effort (CPUE); across five fisheries reserves located along the Zambezi River (Sitwela, Kabweza, and Makangala) and the Kwando River (Luhingi and Qhuqhumupa). Gillnet surveys using both …

Improving Site Quality Estimates in the Upland Hardwood Forests of the Southern Appalachians with Environmental and Spatial Modeling
… hardwood forests of the southern Appalachians, management tools are needed based on the characteristics of the site to quantify the site quality where no accurate maps of site quality exist. Three studies were conducted to achieve this objective. The first study tested if independent measures of …

Development of hay yield monitoring systems
… The focus is on enhancing spatial resolution for site-specific management, involving the use of LiDAR, ultrasonic sensors, and UAV-based remote sensing. It includes detailed analysis, data processing methodologies, predictive model evaluation, and key variable identification. The study is …
