The process of organic matter mineralization in fertilizer mixtures consisting of larch bark and mineral additives was studied in order to optimize the timing of composting and preparation of high-quality fertilizers. The main factors affecting the process of bark mineralization are the reaction of the medium (pH), the ratio of C:N, mineral additives. The process of larch bark mineralization and compositions based on it is described by the equation of the first order. The calculated decomposition constants of fertilizer compositions exceeded the control by 2-3, 2 times depending on the variant of the experiment.
