Introduction: Coffee is a highly mycotrophic plant, its interaction with arbuscular mycorrhizal fungi has been studied among different tropical countries. The majority of the published works indicates that coffee is benefited from the mycorrhizal association, where the AMF confers protection against pathogens and diseases, increases water absorption, as well as it increases the adaptation of the plant at transplant from nurseries to the main plantation. Objective: A review was made where we summarized and analyze the research reports of AMF with coffee from at least the past 10 years, focused on AMF global species distribution, nutritional benefits of the association and interaction with pathogens. Methods: We retrieved available bibliographic data from coffee producer countries in public databases. We considered published works from 2000 to 2019, nevertheless, we included classic papers on the topic, outside that period, mainly the ones performed in Brazil since 1986. We organized the number of reported species per country, we look for synonyms, grouped them by family, genera and species. The reports that only reported genera or where ambiguous were used as reference but not considered for the final analysis. We summarized the reports of the benefits of the AMF interaction in coffee, as well as pathogen tolerance. Results: The collected data shows that there are more than 100 AMF species associated with coffee, which represents more than a third part of the total of reported species worldwide. We found that Colombia has the highest richness, but it also has the highest number of published reports. Conclusions: This information shows the benefits of the incorporation of AMF to coffee plantation programs, because these fungi are a key element in coffee plant nutrition, nevertheless, the coffee variety should be considered when introducing AMF, as not all associations has been efficient.

The aim of this paper is to present a historical series of Colombian GDP from 1888 to 2013. For that purpose we have employed an expenditure approach to reconstruct the GDP for the period 1888-1929. We linked it to the official statistics data of the DANE. The result is expressed in 2011 purchasing parity dollars for international comparisons. [ABSTRACT FROM AUTHOR]

The coffee bean is object of researches in our country since this represents a greater percentage of Colombian exports Several studies have focused on field research, soil survey, pest management, spraying, among other. But there are few researches about coffee beans at the microscopic level, In this paper is the analysis of the vibrational structure of comercial coffee beans, by spectrometric techniques Raman microscopy in situ and Fourier Transform Infrared Spectroscopy (FTIR) for determination of its organoleptic.

Agriculture has drastically transformed landscapes and ecosystems on this planet. These changes alter the supply of goods and ecosystem services thereby impacting human well-being. There are significant environmental impacts associated with modern agriculture and green revolution technologies. This has promoted the development of agricultural production systems that try to reduce the environmental impact and/or improve the well-being of producers. Agricultural certification is one such strategy. This set of management practices promotes agricultural production that simultaneously generates some environmental, social, economic, and quality benefits. Shade-grown coffee production is one of these environmentally-friendly management practices. This paper describes this kind of agricultural production and discusses some of the changes associated with certification as well as the impact it has had on the landscape of Aratoca (Santander). The article also analyzes the differences between certified and non-certified producers. It concludes with some suggestions for the certification process in order to make it a win-win (environment-society) situation for different kinds of coffee growers. [ABSTRACT FROM AUTHOR]
