Reducing Costs

Florida has 915,000 beef cows and 125,000 replacement heifers (USDA, 2016). Developing these heifers so that they can become productive females in the cow herd is a tremendous investment in a cow/calf operation, an investment that takes several years to make a return. The good news is that there are options to develop heifers on forage-based programs with the possibility of reducing costs while simultaneously meeting performance targets required by the beef industry. Mild winters in Florida allows utilization of cool-season forages that can significantly enhance the performance of grazing heifers. During the warm-season, integration of forage legumes into grazing systems will provide additional nutrients to meet the performance required to develop a replacement heifer to become pregnant and enter the mature cow herd. In this document, we will propose a model for replacement heifer development, based on forage research performed in trials at the NFREC Marianna.

The Town

Abstract A small diameter water well drilled in 1977 in the Town of Bulyea, Saskatchewan generated such a rapid plugging (biofouling) that by 1979 the flow rate was reduced by 59%. Heavy growths of non-specific iron bacteria were found in the water and biofouling projected to be the principal cause of the flow loss. Tyndallization (repeated pasteurizations) treatment was applied using a hot water recycling system installed above the well head. Using a displacement passive gravity direct injection of hot water at 82°C from a water heater into the well, a sequential elevation of water column temperatures occurred until bio-film dispersion occurred (pasteurization) at 45°C+. A recovery to original flow specifications was repeatedly obtained at time intervals ranging from 6 to 403 days. Between treatments, a recurrence of biofouling was noted with flow reductions of 0.06 – 0.07 1/min/day frequently being noted. The rate of plugging appeared to be affected by the previous sequence of pasteurization treatments. Tyndallization was found to satisfactorily control iron bacterial biofouling and maintain flow rates.

Resource Situation

A review is provided of the world water resource situation. Water reuse is discussed as a means of augmenting conventional supplies, with types of potential reuse applications identified. Considerations of water quality, cost, public acceptance, and institutional constraints are discussed for their impact on decisions regarding implementation of water reuse.

Current Water

Australia is a relatively dry continent with an average runoff of 50 mm per year. The use of water resources in some river basins is approaching the limits of sustainability. Some adverse environmental impacts have been observed resulting from water diversions and from both reclaimed water and stormwater discharges. The paper describes current water recycling initiatives in Australia. These include: beneficial reuse of reclaimed water for urban, residential, industrial and agricultural purposes; recycling of greywater and stormwater; advanced treatment using membrane technology; and water efficient urban design. Some possible water recycling scenarios for Australia in the 21st century are examined. The implications of these scenarios are discussed.

Performance Target

ABSTRACT In this study, we examine a setting where principals use past performance to annually revise performance targets, but do not fully incorporate the past performance information in their target revisions. We argue that this situation is driven by some principals and agents having an implicit agreement where the principal “allows” the agent to receive economic rents from positive performance-target deviations that are the result of superior effort or transitory gains by not revising targets upward, while the agent “accepts” target revisions by not restricting output when these revisions are the result of structural changes in the operation's true economic capacity. Although both the principal and the agent can benefit from an implicit agreement, we argue that for the implicit agreement to be maintainable, the principal either needs information on the cause of the performance-target deviation or there needs to be trust between the principal and the agent. Using archival data across multiple years and independent bank units, we find a pattern of ratchet attenuation and output restriction that is consistent with the existence of implicit agreements for those principal-agent dyads where information asymmetry is sufficiently reduced or mutual trust exists. Data Availability: Data used in this study cannot be made public due to a confidentiality agreement with the participating firm.
