Exploring variations in potential carbon and nitrogen mineralization in managed grasslands among the diversity of soils in North Carolina

Grassland Research, EarlyView.
Under steady–state conditions, potential nitrogen mineralization in soil under grasslands is closely tied to potential carbon mineralization. This study provides supporting evidence that field–specific nitrogen fertilizer recommendations could be indicated by using a simple and rapid analysis of soil–test biological activity.

Can Ammonium Nitrate Be a Strategic Tool by Replacing Urea as a Nitrogen Supplementation Source to Beef Cattle in Intensified Grazing Systems?

Fermentation
For cattle raised on tropical grass pastures, it is essential to explore strategies that circumvent climatic seasonality that affect forage availability and quality. We hypothesize that the intensification of grazing systems, with rotational and deferred

Existing Accessible Modeling Tools Offer Limited Support to Evaluation of Impact Investment in Rangeland Ecosystem Services

Frontiers in Sustainable Food Systems, 2019
Privately owned rangelands in the western US support many ecosystem services and are threatened by financial incentives favoring conversion to housing development and more intensive forms of agriculture.

An Economic Comparison of Sheep Grazing Systems on the Northern Tablelands of NSW [PDF]

Three 54ha "farmlets" were established in 2000 near Uralla, NSW to trial high input, moderate input and intensive rotational grazing systems. A representative farm approach was used to interpret the profitability results of the trial from July 2000 to ...

Deuteration‐functionalized self‐assembled monolayers for UV‐durable perovskite solar cells

InfoMat, EarlyView.
Modification with deuterophenyl groups has been demonstrated to be an effective strategy for the construction of SAMs. The impressive PCE of 26.34% is by far one of the highest values for PSCs with the carbazole‐based SAMs as HTLs. This UV resistance performance represents the highest level of performance reported to date for PSCs using SAMs as HTLs ...

Vegetation composition and forage mass in grassland with a double structure under two winter grazing regimes

Ciência Rural, 2018
: Remnant areas of Pampas grassland have a distinct double structure. Efficiency of livestock farming on these grasslands depends on practices that are synchronized with natural variation.

Aspects of Bifurcation Theory for Piecewise-Smooth, Continuous Systems

, 2010
Systems that are not smooth can undergo bifurcations that are forbidden in smooth systems. We review some of the phenomena that can occur for piecewise-smooth, continuous maps and flows when a fixed point or an equilibrium collides with a surface on ...

Spatial and temporal variation in survival of female wild turkeys

The Journal of Wildlife Management, EarlyView.
We monitored 370 female wild turkeys across North Carolina's 3 ecoregions from 2020‐2022 to understand factors influencing their survival. Female survival varied by ecoregion and behavior state, with the incubation period having the lowest survival rates. None of the land cover variables affected survival.
