Phosphorus Losses From Simulated Dairy Land Uses of Management Intensive Grazing and Concentrated Animal Feeding Operations
… two forage treatments. Land use treatments were management intensive grazing (MIG) and CAFO hay production to which manure was applied; grazing and CAFO hay production without manure application served as controls. The forage treatments were orchardgrass (Dactylis glomerata) and broad-leafed …

Profitability Analysis of Forage Based Beef Systems in Appalachia
… while abundant, are not necessarily profitable. Management intensive grazing has been suggested as an alternative to traditional production practices to increase profitability. A profitability analysis was conducted by comparing a traditional style of cow-calf management where hay was produced on …

Evaluation of Mob Grazing and its Impacts on Soil Moisture and Temperature and Litter Decomposition in South Dakota
<p>Mob grazing is a type of management intensive grazing system that mimics natural grazing systems where high stocking densities are placed on the land for a short period of time. One way producers measure their success with this system is by the amount of trampled vegetation present after …

Phosphorus Losses from Simulated Dairy Mangement Intensive Grazing Forage System
… the country are evaluating the effectiveness of management intensive grazing (MIG) systems as a means of reducing the economic pressures of confinement feeding and manure handling. Systems using MIG have been promoted as an environmentally safer way of managing nutrient balance on Center. …

Phosphorus runoff potential of different sources of manure applied to fescue pastures in Virginia
… indoor runoff boxes were used to simulate management intensive rotational grazing. Commercial fertilizer TSP and manure application increased runoff TP concentration from 0.146 mg/l to 0.245 mg/l and DRP concentration from 0.105 mg/l to 0.183 mg/l. Runoff P did not differ between organic or …

Stand Density Management for Optimal Volume Production
… data from two thinning studies representing non-intensively and intensively managed plantations, one spacing trial, and one thinning experiment a comprehensive analysis was performed to examine the growth-density relationship in loblolly pine. Volume production was defined as either gross or net …

Optimal reservoir management using adaptive reduced-order models
Reservoir management and decision-making is often cast as an optimization problem where we seek to maximize the field's potential recovery while minimizing associated operational costs. Two reservoir management aspects are considered here, new well placement and production controls. Reservoir …

Innovations in fertilizer use and agronomic management for greater productivity of corn and soybean
… varieties grown under increased levels of management. A steady increase in corn and soybean grain yields have resulted in greater nutrient demands from the soil and fertilizer, resulting in many soil’s nutrient reserves to be drawn down. With the advent of innovative precision agricultural …

Managing the continuous corn yield penalty with crop and residue management
… of this research was to evaluate and determine management practices that could help relieve the yield penalty associated with production of continuous corn compared to when rotated with soybean. This research encompasses two research areas: What are the effects of hybrid selection, enhanced …

Optimizing Corn and Cotton Performance with Adaptive Management Systems and Subsurface Drip Irrigation in the Mid-Atlantic USA
… More data are needed on adaptative corn management strategies that focus on increasing nutrient use efficiencies and crop yields (i.e., 4R nutrient management, biostimulants, and in-season crop protection chemicals). With less than 5% of Virginia's corn and cotton fields irrigated, …
