Economic Analysis of Summer Fallow Management to Reduce Take-All Disease and N Leaching in a Wheat Crop Rotation

Abstract

This paper addresses the question of summer cover-crop adoption by farmers in presence of a risk of yield loss due to take-all disease and climate variability. To analyze the public incentives needed to encourage farmers to adopt summer cover crops as a means of reducing N leaching, we combine outputs from an economic, an epidemiological and an agronomic model. The economic model is a simple model of choice under risk. The farmer is assumed to choose among a range of summer fallow managements and input uses on the basis of the expected utility criterion (HARA assumption) in presence of both climate and take-all Financial support from the French National Research Agency (ANR) within the program Agriculture and Sustainable Development 'IMPACTS' (ADD) is gratefully acknowledged.

“…As fully maturing crops, camelina and pennycress can be integrated into catch cropping systems and offer a potential additional income to farmers by providing a considerable yield (e.g. Shapiro et al (1992) and Flanders et al (2009) describe positive income effects of so‐called double cropping systems).Camelina and pennycress can serve as cover crops and green manure and thus enhance soil quality and benefit the broader environment (Cherr et al , 2006; de Cara et al , 2009). However, the use of temporally fallow agricultural land is only feasible if the oil crops ripen within the seasonal gap between the main crops.…”
