The major citrus production of the world are located between 20-40 degrees north and south latitude. In these conditions the mandarins get the best internal and external qualities.‘Arrayana’ is the main mandarin cultivated in Colombia tropical lowlands (around 04° N). This variety is characterized by a high concentration of the harvest in december and january because it has only one principal bloom in the year (two weeks after onset of rainy season); and an average external quality that prevents it from being highly competitive.

Acid sulfated soils are characterized by high amounts of iron and sulfur, which in presence of air are oxidized and form sulfuric horizons extremely acidic, generating environmental changes ranging from water pollution to problems associated with fertility and crop production, among others. This research was conducted in order to identify suitable plant species to control the acidity of these soils in the town of Paipa, Boyacá, Colombia. A completely randomized experimental design with 6 treatments and 3 replications was implemented in potting shed; there, the response of Beta vulgaris L.

La Mojana region is located in the North Coast of Colombia. It is part of the alluvial extensive plain, where the Cauca, San Jorge and Magdalena rivers flow together. The region is representative of the tropical humid forest, and is affected by annual flooding cycles. The predominant soils are inceptisols, entisols, oxisols and vertisols. Human activity has been reported since pre-Columbiam times, with the Zenu culture.

The aim of this study was to determine some aspects of the distribution and habitat availability for the subspecies Tapirus terrestris colombianus in the low lands of the northern Central Mountain Chain in Colombia, which is known as the Antioquian Northeast. The results confirm the presence of this subspecies in 20 new recording localities. The habitat availability was estimated by locating the records on images of vegetation covertures, being primary forest the predominant vegetation followed by bushland.

The genus Capsicum belonging to Solanaceae family enjoys favorable conditions for successful development in the Colombian Amazon. Five accessions of the Germplasm collection of Amazonian Capsicum of the Institute SINCHI were selected for their high pungency to study the growth, development and the effect on the patterns of interception of photosynthetic active radiation (PAR), production and quality of fruits under three planting distances (50, 60 and 70 cm between plants). For this purpose, an experiment was conducted in field conditions in Florencia, Caqueta.

In the Andean region of South America, understanding communities’ water perceptions is particularly important for water management as many rural communities must decide by themselves if and how they will protect their micro-watersheds and distribute their water. In this study we examine how Water User Associations in the Eastern Andes of Colombia perceive water scarcity and the relationship between this perception and observed climate, land use, and demographic changes. Results demonstrate a complex relationship between perceptions and observed changes.

Achievement of environmental management goals and objectives in coastal areas, including how to measure success, remains a significant subject for discussion among scholars and practitioners, meanwhile four distinct management efforts potentially converge within the coastal zone: land-use planning (LUP), river basin management (RBM), marine spatial planning (MSP) and integrated coastal management (ICM).

Native arbuscular mycorrhizal fungi associated with grass and legume cover crops established on Oxisol soils in the Colombian piedmont (Meta) were identified morphologically and the ability to colonize was evaluated. The experimental area consisted of cover crops Arachis pintoi (CIAT 18744), Brachiaria brizantha cv. Toledo, B. dictyoneura cv. Llanero, Desmodium ovalifolium cv. Maquenque, Panicum maximum (CIAT 36000), Paspalum notatum, and a chemical control (Glyphosate and mechanical control) established in the rows in a Valencia orange grove.
