Nitrogen (N), being the most critical and essential nutrient for plant growth, largely determines the productivity in both extensive- and intensive- grassland systems. Nitrification and denitrification processes in the soil are the primary drivers generating reactive-N: NO3-, N2O, and NO, and is ...

Los sistemas silvopastoriles en donde se asocian gramíneas y leguminosas forrajeras son de mucha importancia debido a los beneficios que se pueden obtener con ellos, como el aumento de la productividad, y los servicios ecosistémicos que pueden prestar. Estos sistemas representan una opción válida...

Expansion of crop production into high-altitude native grasslands is occurring in the Peruvian High-Andes due to climate change and agricultural intensification, with little understanding of the consequences to the ecosystem. The objective of this study was to determine the impact of land-use cha...

The factors of grazing management that influence tropical pasture utilization are discussed in this review. The principal objective is to consider stocking rate and grazing system effects-and their interaction-as related to the evaluation of germplasm under grazing. It is inferred that the study ...

Variations in sward canopy structure can exert an important influence on the ingestive behavior of grazing animals and hence on herbage intake and utilization. In tropical swards, the structural characteristics of major importance appear to be total herbage density or leaf bulk density and leaf-t...

An approach for combining remote sensing spectral measurements with an ecosystem model was presented in an accompanying article. The sahelian grassland ecosystem STEP model developed for that purpose was also described and validated. In order to fulfill a prerequisite for using coarse resolution ...

Toward the control of its simulations by remotely sensed indices

An approach to combining remote sensing spectral measurements with an ecosystem process model is presented. In this approach, the ecosystem model is not bound by the sole use of satellite data, but integrates the latter in an explicit formulation of the main processes of vegetation functioning. A...

In 1998, Fisher et al. attempted to draw together published and anecdotal information to answer some of the questions raised by the findings of Fisher et al. (1994; 1995), that introduced pastures of African grasses on the eastern plains of Colombia accumulated large amounts of C in the soil. Thi...
