Bulletin of Chinese Academy of Sciences (Chinese Version)
The black soil in northeast China presents a trend of thinning, hardening, impoverishment, and acidification under the longterm high-intensity utilization, and faces the water resources shortage and ecological environment imbalance. Thus, the coordination between soil and water resources and environment has become the bottleneck of sustainable agricultural development in northeast China. The black soil protection and utilization is not only a problem of cultivated land system itself, but also a problem of harmonization of mountain-river-forest-farmland-lake-grassland-sandy land ecosystem. To achieve the goal of sustainable use of the black soil, it is necessary to give full play to the function of soil …

It is not uncommon for rural Nebraska coffee shop talk to touch on the topic of who is involved or not involved in the community. Typically, the conversation comes to the conclusion that the same people seem to be doing everything. The topic could relate to a civic group, community event, or even an elected office in the community. There are no new faces and no new ideas as well as there is no one there to allow for a leadership transition. Have you ever heard this conversation? Have you participated in it?

Optimal Regulatory Response To Food Fraud, Syed Imran Ali Meerza, Konstantinos Giannakas
Cornhusker Economics
Food fraud refers to the deliberate substitution, addition, tampering, or misrepresentation of food for economic gains. In this context, food fraud can be divided into two broad categories: food adulteration and mislabeling. While food adulteration can be defined as the intentional substitution or addition of substances in a food product to reduce its costs of production, mislabeling refers to acts of misrepresentation of the type or quality of food products. Food fraud is motivated by economic gains and is enabled by the fact that information about the nature of credence goods is typically asymmetric – while product suppliers know the …

Evaluating Alternative Feed Sources During Drought, Matthew D. Garcia, Ruger P. Carter, Ryan Larsen, Eric Thacker, Jacob Hadfield, Reganne K. Briggs, Justen Smith
All Current Publications
During years of drought, it is important to critically evaluate alternative feed sources available for cattle. The traditional method for sustaining a herd through a drought is feeding extra stored forage to compensate for decreased forage production or decreased forage quality available on rangelands and pastures due to drought conditions. However, hay prices rise substantially, and availability decreases due to irrigation water limitations and increased demand from livestock producers. This fact sheet will evaluate why hay prices rise and what alternatives are available to compensate for forage reductions during drought.

It is germane to know the characteristics and practices of small livestock producers in order to assist them; however, there are a paucity of investigations on the subject in the Southeastern US. Thus, this study assessed selected producer characteristics and production practices of small livestock producers in three Southeastern States. The data were collected from three samples of producers in several counties of Alabama, Georgia, and Florida, and were analyzed using descriptive statistics. The results showed that, a majority of producers practiced rotational grazing, had parasite problems, quarantined newly acquired animals, and used veterinary services. Additionally, a majority sold their …

Determining The Accuracy Of Holstein Bull Semen Prices With A Two-Tier Efficiency Model, Loren W. Tauer
Journal of Applied Farm Economics
The pricing accuracy of dairy bull semen available for artificial insemination is investigated using a price model cast in terms of a two-tier efficiency model, which allows estimating an overprice and underprice given the net return the bull’s daughter is expected to contribute to the farm based upon the transmittable trait characteristics of a bull. The estimation produces statistically significant coefficients, including the coefficients for the overpricing and underpricing of the semen. The average estimate of overpricing is around 25%, and the average estimate of underpricing is around 33%. As expected, low semen prices tend to be underpriced and high …
