The farmer’s irrigation technology choice problem is as follows:
The search for a maximum consists of two stages. First, the optimal amount of applied water (a continuous choice) is determined conditional on each technology. Then, working backwards, the highest-profit technology is identified.
The applied input choice is determined by the following:
The Future Operating Capability (FOC) is
In words, this optimization condition implies that the Value of the Marginal Product (VMP) of effective water must equal the marginal price of effective water. Once the second-stage, continuous problem is solved, the discrete choice problem of technology selection must be addressed, choosing
The model generates a number of testable hypotheses about the influence of environmental and market conditions on adoption of precision technology. Con-

As of 2013, the National Science Education Standards have been replaced by the Next Generation Science Standards (NGSS), available as a print book, free PDF download, and online with our OpenBook platform.
The NGSS offer a detailed description of the key scientific ideas and practices that all students should learn by the time they graduate from high school. The standards are based largely on the 2011 National Research Council report A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas.
