Foliar application of inorganic nutrients and organic acids can affect the metabolic profile of soybean leaves and enhance soybean productivity. In this study, we investigated whether foliar application of 12 inorganic nutrients [N, P, K (10 g L −1 each); Ca, Mg, B, Zn, Fe, Cu, Mo, Si (200 g L −1 each); Se (20 g L −1 )] and five organic acids [acetic, ascorbic, citric, formic, and malic acids (200 mM each)] could alter seconda...
