The Economics and Management of Water and Drainage in Agriculture

Jan van Schilfgaarde, USDA Agricultural study carrier and nationwide study Council Committee on Irrigation-Induced Water caliber difficulties In 1982, a startling discovery was once made. Many waterbirds in Kesterson nationwide flora and fauna safe haven have been loss of life or soreness reproductive failure. situated within the San Joaquin Valley (Valley) of California, the Kesterson Reservoir (Kesterson) was once used to shop agricultural drainage water and it was once quickly decided that the possible explanation for the wear to flora and fauna used to be excessive concen­ trations of selenium, derived from the water and water organisms within the reservoir.

This would also explain the behavior of the herbicide-machinery price ratio (Fig. 4). If a price time series is not adjusted for quality, or it is only partially adjusted, the price will increase with time at a faster rate than a fully quality-adjusted price series.

This would also explain the behavior of the herbicide-machinery price ratio (Fig. 4). If a price time series is not adjusted for quality, or it is only partially adjusted, the price will increase with time at a faster rate than a fully quality-adjusted price series. Thus, a herbicide/machinery price series in which the machinery prices were not fully adjusted for quality will decline at a slower rate compared to a series fully adjusted for quality.

The Eqs (1)-(3) are estimated together using the data in an iterated seemingly unrelated regression (ITSUR) framework (Zellner, 1962). After model estimation and statistical testing, the short and long-run impact of relative prices and the long-run effect of private and public research stocks on the herbicide/labor, herbicide/machinery, and herbicide/land ratios are measured in elasticity form.
