Agriculture is one of the economic activities with the most potential in Colombia, given its climatic and geographical conditions. Bean cultivation is classified as climbing, which grows in a branched way, and bushy, whose growth occurs up to 70 cm. The objective of this research was to study zinc and iron sulfates in different concentrations as fertilizers capable of increasing the nutritional value of kidney beans ( L.), whose strategy is known as biofortification, and thus determine the most effective sulfate. The methodology details the sulfate formulations, their preparation, the application of additives, sampling and quantification methods of total iron, total zinc, °Brix, carotenoids, chlorophylls a, b, and antioxidant capacity using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method in leaves and pods. As for the results, it was found that biofortification with iron sulfate and zinc sulfate is a strategy that favors the country's economy and human health, because it allows the increase of minerals, antioxidant capacity and total soluble solids.
农业是哥伦比亚最具潜力的经济活动之一，这要归功于其气候和地理条件。豆类种植分为攀缘型和丛生型，攀缘型分枝生长，丛生型生长可达 70 厘米。本研究的目的是研究不同浓度的硫酸锌和硫酸亚铁作为肥料，以提高菜豆（Phaseolus vulgaris L.）的营养价值，这种策略被称为生物强化，从而确定最有效的硫酸盐。该方法详细说明了硫酸盐的配方、制备方法、添加剂的应用、叶片和豆荚中总铁、总锌、°Brix、类胡萝卜素、叶绿素 a、b 和抗氧化能力的采样和定量方法，使用 DPPH（2,2-二苯基-1-苦基肼）法。至于结果，发现用硫酸亚铁和硫酸锌进行生物强化是一种有利于国家经济和人类健康的策略，因为它可以增加矿物质、抗氧化能力和总可溶性固体。
