From strategy to reality: the path to institutional excellence in harsh times
(CATIE, Turrialba (Costa Rica), 1997)
Effects of landuse and weathering on available nutrients in volcanic ash soils of Costa Rica: a comparative study
(CATIE, Turrialba (Costa Rica) | Ministerio de Agricultura y Ganadería, San José (Costa Rica) | Agricultural University of Wageningen, Wageningen (Países Bajos), 1997)
In the present study two soiltypes, a highly depleted, old soil and a young, fertile soil are compared under three landuse types. The focus of the study is soil moisture and its chemical composition. As a reference, soil ...
A farm typology for the Atlantic Zone
(CATIE, Turrialba (Costa Rica). Atlantic Zone Programme Agricultural University Wageningen, Wageningen (Países Bajos) Ministerio de Agricultura y Ganadería, San José (Costa Rica), 1997)
In land use analysis it is often necessary to generalize individual farMON into a number of farm types. In this research the farm typology is based on the physical production possibilities presented by farm size and soil ...
The effects of propagation environment and foliar area on the rooting physiology of Cordia alliodora (Ruiz & Pavon) Oken cuttings
(Springer, Berlín (Alemania), 1997)
Substrate conditions, foliar nutrients and the distributions of two canopy tree species in a Costa Rican secondary rain forest
(1997)
A 28 yr old secondary lowland rain forest in Costa Rica was dominated by two tree species of contrasting ecologies, Vochysia ferruginea - a species typical of well-drained but infertile soils of high AL saturation, and ...

(CATIE, Turrialba (Costa Rica), 1997)
The impact of land degradation on agricultural productivity a multi-period economic land use model; a case study of the Neguev settlement, Costa Rica
(CATIE, Turrialba (Costa Rica). Agricultural University Wageningen, Wageningen (Países Bajos). Ministerio de Agricultura y Ganadería, San José (Costa Rica), 1997)
Current land use practices will have to be sustainable in order to guarantee a sufficient level of agricultural production for future generations. In this study a sub-regional multi-period linear optimization model of ...
Redistribution of trace elements upon the weathering of volcanic ash soils in Costa Rica
(Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), Turrialba (Costa Rica). Atlantic Zone Programme Agricultural University Wageningen, Wageningen (Países Bajos) Ministerio de Agricultura y Ganadería, San José (Costa Rica), 1997)
Redistribution of trace elements upon weathering over Al/Fe-humuscomplexes and amorphous minerals was studied in a sequence of soils derived from andesitic ash on the Turrialba volcano in Costa Rica. All profiles are located ...
