An expt. was established in Esparza (Costa Rica), on the integrated management of web blight (Thanatephorus cucumeris) in common beans under the min. tillage system. Var. Porrillo 70 (intermediate resistance) and ICA Pijao (susceptible) were used. Herbicides gliphosate and paraquat (1.0 kg/ha) of...

Oxisols such as those of the Colombian Eastern Plains (Llanos) are susceptible to physical, chemical and biological degradation once brought into cultivation, especially under intensive use of machinery. The main objective of this study was to determine the impact of intensive disc harrowing (2, ...

The objective of this work was to assess the effects of integrated crop-livestock systems, associated with two tillage and two fertilization regimes, on the abundance and diversity of the soil macrofauna. Four different management systems were studied: continuous pasture (mixed grass); continuous...

Smallholder agroforestry systems often incorporate features that are associated with abundant, diverse soil macrofauna populations. This study sampled soil macrofauna communities across four major land uses present within agricultural landscapes where the Quesungual Slash-and-Mulch Agroforestry S...
