Impacts of Productivity Loss on Crop Production and Management in a Dynamic Economic Model
研究了农民在预期土壤侵蚀会降低产量时,如何选择最优的耕作方式和作物轮作,发现作物价格上涨会促使农民采取更保护土壤的做法。
Abstract This article finds the optimal choice of tillage method and crop rotation for farmers who correctly anticipate the yield‐decreasing effects of soil erosion. Expected increases in crop prices lead to farming practices that are more conservation oriented. Higher relative prices for hay also lead to more soil conservation. A linear programming model of soil loss is presented for a watershed in Tama County, Iowa.
