Laboreo de conservación: tendencias y prioridades de investigación

Abstract

[ES] La reducción del laboreo, como estrategia para el control de la erosión y para la optimización de las explotaciones agrícolas, está recibiendo una creciente atención. En el presente trabajo se analiza la evolución entre 1975 y 1989 de las investigaciones sobre esta alternativa de trabajo del suelo. En el análisis bibliométrico realizado se han considerado las publicaciones sobre laboreo en general y, dentro de ellas, las relativas a laboreo de conservación. También se han contabilizado los trabajos de laboreo relacionados, entre otros aspectos, con erosión y conservación de suelo y agua. Las tendencias y contribución relativas según países y/o regiones mundiales se han estimado por comparación de la producción científica de los períodos 1975—77 y 1987—89. Mientras que el total de publicaciones sobre laboreo del suelo se ha triplicado, el número de referencias específicas sobre laboreo de conservación ha aumentado aproximadamente cinco veces. Por otro lado, aunque se observa un cierto incremento en el número de trabajos dedicados al estudio de la erosión, su porcentaje con respecto al total sigue siendo insuficiente, especialmente en el caso de la región mediterránea. Finalmente, se analiza la oportunidad y características de un programa de investigación sobre laboreo de conservación para la agricultura de secano en la Depresión Media del Ebro.

[EN] The development and adoption of reduced tillage practices over the last two decades has proven to be an important factor in controlling soil losses in cultivated fields. In order to evaluate the growth pattern of conservation tillage research conducted in the last fifteen years, a bibliometric analysis, based primarily on abstracts published in Soils and Fer-tilizers, has been performed. The contribution to world output for different geographical regions has been assessed comparing the amount of scientific and technical publications for the 1975—77 and 1987—89 periods. While the output of total tillage related papers has increased only three times in that period, that of conservation tillage papers has increased five times. Though a slight trend to increase the number of papers dealing with soil erosion can be noted, much more attention should be paid to this issue in the Mediterranean region, specially under dryland conditions. A priority research program on new conservation tillage systems for the middle part of the Ebro river valley, NE Spain, is briefly outlined.
