- Basil is a promising crop in Colombia due to its high adaptability and demand in export markets. However, there are no studies focused on nutrient absorption dynamics under local conditions, which would allow for the identification of nutrient uptake dynamics throughout the production cycle. The objective of this study was to examine the dynamics of minerals uptake, distribution, and accumulation in two basil cultivation systems (conventional fertilization and alternative mineral fertilization). Two experimental trials were established in commercial plots located in the municipalities of El Espinal and Mariquita (Tolima Department, Colombia), using a randomized complete block design with three replications. Two fertilization programs designed by the producers were used: (i) conventional fertilization using highly soluble fertilizers, and (ii) an alternative mineral fertilization program based on acids, sulfates, and mineral inputs. During six harvest periods, yield, macro-and micronutrient content, and dry matter accumulation in leaves, stems, and roots were determined. In general, it was found that the order of greatest minerals accumulation was K > N > Ca > Mg > P > S > Na > Fe > Zn > Mn > B > Cu for both production schemes. Additionally, the mineral alternative fertilization production system achieved a total of 17 t ha-1 (El Espinal), while the conventional system recorded 11 t ha-1 of dry matter (Mariquita). Finally, alternative mineral production registered a 46.22% increase in the total major element’s uptake and around 25.25% increase in the total minor element’s uptake compared to the conventional scheme, a response that was highly influenced by nutrient management and plant density. © 2025, Universidad Pedagogica y Tecnologica de Colombia.
