| Descripción: | Homemade foliar fertilizers are an efficient fertilization tool, especially in productive systems that are managed under agroecological approaches. Some advantages of these fertilizers are that their preparation does not require sophisticated equipment, specialized training or expensive materials. There is a great variety of homemade foliar fertilizers, for example, super magro, bioles, hydrolyzed humus tea, and others; It is necessary to ensure that these fertilizers fulfill the function for which they are applied, which is to provide nutrients that can be absorbed foliarly, favoring plant nutrition. This is precisely the topic to be addressed in this review, specifically, technical aspects of the preparation of homemade foliar fertilizers are reviewed in the light of three topics: 1) morphological and functional aspects of the leaf, which has a direct impact on the process of foliar absorption of nutrients, 2) the chemical nature of the inputs (i.e., plant, animal and mineral origin) used in the manufacture of homemade fertilizers, and 3) the process of preparation (i.e., hydrolysis, fermentation), which will enable the transit of nutrients through the barriers imposed by the leaf structure. On the other hand, additional mechanisms through which homemade foliar fertilizers can benefit plant production are mentioned. Therefore, the objective of this evaluative review is to analyze some technical aspects that will directly influence the effectiveness of homemade foliar fertilizers, to predict their contributions to crop development. |
