Effect of mineral liquid organic fertilizer on soil and morphological/physiological parameters in ICA Cerinza bean cultivation until flowering stage

Purpose: The production of beans and food in general at the global level has been threatened by the high costs of industrially synthesized fertilizers. Therefore, the goal of this work was to evaluate the effect of a mineral organic liquid fertilizer (MOLF) on the chemical properties of the soil and the morphological and physiological parameters in ICA Cerinza bean cultivation up to the flowering stage. Methods: The crop was established in open fields in bags and randomly distributed. Aerobic fermented MOLF and commercial liquid fertilizer were evaluated up to the flowering stage. The behavior of micro and macronutrients in the soil was determined using Mehlich-3 and Bray II extractants. In addition, physiological parameters were evaluated in the plants. Results: The incorporation of MOLF in ICA Cerinza bean cultivation increased the content of available P, with results very similar to those of commercial fertilizer. Higher values were observed in chlorophyll content compared to commercial fertilizer. Fluorescence data showed heterogeneous behavior in treatments and which was associated with nutrient content in the soil. Oxalic, citric, formic, acetic, lactic, and succinic acids were identified, with their concentration being higher in the early stages of growth and their production was closely related to the P content and the addition of MOLF. Conclusion: This study demonstrates the potential of using MOLF in bean crops, improving the availability of nutrients in the soil and promoting the secretion of organic substances that can contribute to nutrient mobilization, contributing to fundamental stages such as flowering. Highlights · Leachates from composting stabilized through aerobic fermentation can be used as organic amendments to enhance soil properties. · The use mineral organic liquid fertilizer can be improving nutrient availability in the soil and enhancing the secretion of organic substances that can contribute to nutrient mobilization. · The application of mineral organic liquid fertilizer has effects on the physiological response of Ica Cerinza beans. · Six organic acids (oxalic, citric, formic, acetic, lactic, and succinic) were identified, with higher concentrations in the early growth stages, and their production was closely related to P content and the addition of LOMF. · Elevated values were observed in chlorophyll and fluorescence data, which exhibited heterogeneous behavior. These variations are linked to nutrient content in the soil and the presence of Deroceras reticulatum.
