Sažetak

The present paper investigates the effectiveness of different levels of applied digested residue obtained after anaerobic digestion (AD) of meat-bone meal (MBM) on the morphologic and mineral characteristics of corn. The experiment was conducted in duration of two years and consisted of eight treatments: control (without any fertilizer); mineral fertilization only; treatments with minimum, medium and maximum dosage of digested MBM; fertilization of minimum, medium and maximum dosages of AD residue combined with mineral fertilizer. By combination of treatments with mineral fertilizer and different rates of AD residue, plants increased mass yield, they were larger and had more leaves. Content of mineral substances was within average values, both in plant material and in kernel, and variations in values were conditioned by total mass and ion interactions. MBM after AD treatment is possible to be applied as organic fertilizer. It has higher nutritive value and, as such, is suitable for treatment of agricultural plants, especially in crop production.
