Ano: 2004 URL: http://purl.umn.edu/32715 THE IMPACT OF CONSERVATION TILLAGE ON THE PRODUCTIVITY AND STABILITY OF MAIZE CROPPING SYSTEMS: A CASE STUDY IN WESTERN MEXICO AgEcon Jourdain, Damien; Scopel, Eric; Affholder, Francois. This paper examines the economics of introducing conservation tillage into maize cropping systems in the state of Jalisco, in the western part of Mexico. A stochastic cost-benefit analysis (SCBA) of introducing conservation tillage in two contrasting agro-climatic zones in the four main maize management systems in the area was carried out. The SCBA takes into account the effects of conservation tillage on average returns and fully evaluates its potential risk-reducing aspect. The SCBA results were then used for a stochastic dominance analysis to evaluate farmers' incentives, characterized by their aversion to risk. The analysis reveals that although conservation tillage is economically viable, cash-constrained farmers, especially in the dry areas, may not...

Solo Nascimento,Alexandre Ferreira do; Mendonça,Eduardo de Sá; Leite,Luiz Fernando Carvalho; Neves,Júlio Cesar Lima. The aim of this study was to calibrate the CENTURY, APSIM and NDICEA simulation models for estimating decomposition and N mineralization rates of plant organic materials (Arachis pintoi, Calopogonium mucunoides, Stizolobium aterrimum, Stylosanthes guyanensis) for 360 days in the Atlantic rainforest bioma of Brazil. The models´ default settings overestimated the decomposition and N-mineralization of plant residues, underlining the fact that the models must be calibrated for use under tropical conditions. For example, the APSIM model simulated the decomposition of the Stizolobium aterrimum and Calopogonium mucunoides residues with an error rate of 37.62 and 48.23 %, respectively, by comparison with the observed data, and was the least accurate model in the...
