Smartphone‐Based Monitoring Identifies the Importance of Farm Size and Soil Type for Coffee Tree Productivity at a Large Geographic Scale

Journal of Sustainable Agriculture and Environment
Smartphone‐based monitoring has been increasingly applied to coffee crops for multiple tasks, such as predicting coffee tree productivity. However, its implementation remains limited to small‐scale use, typically at the individual plant level.

Using the MAESTRA model to simulate light interactions and photosynthesis in a heterogeneous agroforestry system under alternative density [PDF]

, 2012
Coffee-based agroforestry systems display two heterogeneous plant layers (shade tree and coffee) both discontinuous, uneven-aged and subjected to sequential pruning. Many field experiments in coffee agroforestry research have been implemented to evaluate

Tree diversity on sustainably certified and conventional coffee farms in Central America [PDF]

, 2015
Shade coffee agroforestry systems have the potential to support biodiversity. Sustainable certification of coffee has been promoted as a means to provide incentives to maintain these systems, but as yet there is little evidence if this is effective.

An Edible H2O2 Biosensor for Gastrointestinal Metabolites and Peroxidase Enzyme Quantification

Advanced Healthcare Materials, EarlyView.
We present an edible biosensor for gastric fluid analysis that integrates a caffeic acid–horseradish peroxidase redox system into an edible electrolyte‐gated transistor. The device enables rapid, low‐volume detection of H2O2 and, with minimal modification, metabolites and enzyme activity in simulated gastrointestinal conditions.

Nitrogen fixing shade trees in coffee agroforestry: Quantification of nitrogen transfer to the coffee plant [PDF]

, 2019
Nitrogen-fixing shade trees in coffee agroforestry systems are assumed to provide an alternative nitrogen source for the coffee crop when fertilizer applications are low, but the transfer of nitrogen from shade trees to the coffee crop has not yet been ...

Different sources of phosphorus in coffee tree formation

Revista Brasileira de Engenharia de Biossistemas, 2022
Arabica coffee is one of the main crops in Brazil and requires balanced nutrition. Among the nutrients, phosphorus is essential in planting so that seedlings can be successful in the after transplanting, allowing a good development and growth. The use of quality seedlings and balanced fertilization is essential for this, however, Brazilian soils, due ...

THE GROWTH AND YIELD OF COFFEE ARABICA IN SHADE CONDITIONS ON DIFFERENT TREATMENT OF PRUNING AND FERTILIZING [PDF]

Russian Journal of Agricultural and Socio-Economic Sciences, 2020
Coffee plants are C3 plant groups, with characteristic of low photosynthetic efficiency, which is due to the occurrence of photorespiration. In simple agroforestry systems, legumes are commonly used as shade trees.
