Resurging southeastern cotton production compels better cotton acreage forecasts for planning seed, chemical, and other input requirements. Structural models describe leading acreage response indicators, and forecasts are compared time-series models. Cotton price, loan rate, deficiency payments,...

Resurgent cotton production compels better acreage forecasts for planning seed, chemical, and other input requirements. Structural models describe leading acreage response indicators, and forecasts are compared to time-series models. Cotton price, loan rate, deficiency payments, lagged corn...

The ornamental horticultural industry continues to be one of the most rapidly expanding sectors in agriculture.

Economic theory provides little guidance for selecting a numeraire in estimating dual function profit functions. In this study, we examine the choice of numeraire price (equation) for profit function models of Iowa agriculture. The choice of numeraire is evaluated by forecasting accuracy and...

Poultry litter can be used as plant nutrients or cattle feed. Both of these alternatives may increase phosphorus concentration in the nearby watershed. Use of phosphorus consistent litter application rule in nutrient management combined with permit system has potential to curtail the over...
