Do farmers waste fertilizer?

24 Jul 2007

The inherent uncertainty about weather may induce even risk neutral farmers to apply more than the average if the expected gains from applying a bit more in the good years outweighs the expected cost of this extra nitrogen that is unused by the crop in the poor years. [...] A moldboard plow was used in the fall of the previous year in five of the experiments and mulch-tillage in the other two trials. [...] The ex post MERN estimated with a quadratic-plateau, which is the underlying response model in the recommendation, was higher than the recommend rate on half of the 6 sites but lower on the other half. [...] The differences between the recommended and MERN were correlated with the yield potential to determine if the basis for the recommendation should be adjusted. [...] The skewness of the distribution is negative and given that the recommended rate is higher than the ex post MERN for many of the situations in those two years, the result is due to a few large differences.
