Injection into the soil organic fertilizers, which consist of the main chemical elements (nitrogen, phosphorus, potassium), improves the soil dynamics of biological processes. The best effect is achieved when the fertilizer is placed locally, i.e. during the seeding process in the plant root system development zone. For that reason, it is economically expedient to create and use a granular organic fertilizer (cattle, poultry manure, and organic compost) with relevant physical-mechanical properties, which influence the product warehousing (storage), transport, straggling spreading in the soil and localized insertion. The physical-mechanical properties were determined (bulk density 770-680 kg•mE-3, natural slope 30.5-34.4º and the inrush failure angles 43-47º, mechanical durability of pellets more than 86 %, etc.) of experimental granulated organic fertilizer produced by different technologies, because the physical-mechanical properties have a significant influence on the technological product parameters.
