Shade tree Chloroleucon eurycyclum promotes coffee leaf rust by reducing uredospore wash-off by rain
(Elsevier, Ámsterdam (Países Bajos), 2020)
addition, may interact with environment. To better understand shade trees effects on coffee leaf rust (CLR), we
studied three disease stages separately: sporulation, uredospore wash-off by rain, and uredospore deposition ...
The positive association between natural vegetation, native coccinellids and functional diversity of aphidophagous coccinellid communities in alfalfa
(2021-01)
1. A greater taxonomic and functional diversity of natural enemies in agroecosystems is frequently positively associated with more effective pest control, due to the complementarity of species or traits. But this diversity ...
Measured ammonia emissions from tropical and subtropical pastures: A comparison with 2006 IPCC, 2019 Refinement to the 2006 IPCC, and EMEP/EEA (European Monitoring and Evaluation Programme and European Environmental Agency) inventory estimates
(American Dairy Science Association, Champaign, IL, EUA ; Elsevier, Ámsterdam, Países Bajos, 2020)
Agriculture is the largest source of ammonia (NH3) emissions. As NH3 is an indirect greenhouse gas, NH3 measurements are crucial to improving greenhouse gas emission inventory estimates. Moreover, NH3 emissions have wider ...
Economic constraints as drivers of coffee rust epidemics in Nicaragua
(Elsevier, Ámsterdam (Países Bajos), 2020)
Coffee rust (Hemileia vastatrix) epidemics of an intensity never seen before have hit Central America since 2012.
This study set out to identify management and socio-economic factors that facilitate coffee rust development ...
Cacao agroforestry systems improve soil fertility: Comparison of soil properties between forest, cacao agroforestry systems, and pasture in the Colombian Amazon
(Elsevier, Ámsterdam (Países Bajos), 2021-01)
The objective of our work was to evaluate soil quality in different cacao agroforestry systems (AFS) in the Colombian Amazon. We compared soil quality of AFS at the study site with soil quality of two control systems: a ...

Cacao cultivation is one of the most important livelihoods for rural households in Colombia, where it is promoted as a substitute for the illegal cultivation of coca. To strengthen Colombian cacao farming, it is important ...
Prediction model for sap flow in cacao trees under different radiation intensities in the western Colombian Amazon.
(2021-01)
In this study, we measured diurnal patterns of sap fow (Vs) in cacao trees growing in three types of agroforestry systems (AFs) that difer in the incident solar radiation they receive. We modeled the relationship of Vs ...
