Qrop® Sul K is a potassium fertilizer that contains sulfur, all in one granule. Its sulfur is 100% soluble, which is why both potassium and sulfur have a fast delivery after they are incorporated into the soil, because it doesn´t need chemical or biological transformations, it only needs moist soil to be incorporated. However, in the case of crops that have a cycle longer than 90 days, it is recommended only at the beginning of the process. In later applications, a fraction of the potassium in Qrop® Sul K will fail to dissolve due to lack of time, and therefore, we recommend its application at the beginning of the cultivation process or in base mixtures.
