TL;DR: In this article, the potential economic and environmental effects of broad versus targeted nitrogen use policies are evaluated in five Central High Plains subregions and it is shown that per-acre restrictions are more effective than total nitrogen restrictions in reducing expected nitrogen losses in runoff and percolation, and reducing percolations losses at all probability levels.

TL;DR: In this article, a farm-level risk programming framework is presented which evaluates income/environmental risk tradeoffs, and the model is applied to a representative farm in the Oklahoma Panhandle region of the Central High Plains.

TL;DR: In this article, a computerized grain sorghum plant growth model using daily weather observations was used to compare water-conserving irrigation strategies in an area of declining ground water supplies.

TL;DR: In this article, the authors use concepts such as the payback period, average rate of return, internal RROI, and net present value to evaluate alternative investment alternatives to the assumption of perfect knowledge.

TL;DR: In this article, uncertainty is a pervasive phenomenon in production agriculture, including weather events, diseases, insect infestations, general economic conditions, the development and adoption of technological innovations, and public and private institutional policies, interact to create a unique decision making environment for the agricultural producer.
