Recently, the use of granular fertilizers in agriculture has been expanding rapidly due to their favorable properties in improving the environment and increasing operational efficiency. Therefore, a qualitative and economic evaluation of the precise application of granular and non-granular organic fertilizers has been performed in this work. The evaluation of the uneven application of organic fertilizers was performed by spreading cattle manure, manure granules, and lime in the spreading spreader “Rollforce” 5517. The economic evaluation was performed for mechanized technological operations of loading, transportation, and distribution of organic fertilizers, estimating the price of used aggregates and consumed fuel, the cost of individual technological operations, and other indirect costs. Studies have shown
that manure is easier to spread over a wider area than pellets and lime, as manure particles are much larger and heavier. The lowest costs (180 Eur ha-1) for the purchase of organic fertilizers are incurred using manure, but in the evaluation of mechanized technological operations, the lowest costs (2.32 Eur ha-1
and 6.65 Eur ha-1
) are obtained for fertilization with meat and bone meal pellets, and manure pellets.
