Influence of physical properties of fertilizer on spreaders working quality

Abstract

Proper choice and efficient utilization of various technological-technical application systems still has a significant importance concerning ecology, energy and economy in agriculture. Due to the predominant practice of using granulated mineral fertilizers an analysis of mineral fertilizer processing including its production, manipulation and application was made. Physical and mechanical characteristics of mineral fertilizers and fertilizer reaction with the application systems are of outmost importance in fertilizer application system choice. Successful utilization of mineral fertilizers predominantly depends upon the interaction between mineral fertilizers physical-mechanical characteristics and the appropriate type of spreader. The aim of this paper was to analyze working quality of two centrifugal spreaders in relation to physical properties of applied fertilizers in the conditions of seed-bed preparation for corn seeding.

Značaj mineralnih đubriva u savremenoj biljnoj proizvodnji kako u agrotehničkom i ekološkom pogledu aktuelizuje izbor i efikasno korišćenje tehnološkotehnoloških sistema aplikacije. Dominantna praksa korišćenja čvrstih mineralnih đubriva (granulata) nameće celovitu analizu procesa mineralnih đubriva koji podrazumeva proizvodnju, manipulaciju i aplikaciju. Interakcija fizičko-mehaničkih svojstava mineralnih đubriva i tipa rasipača od presudnog je značaja za uspešnost primene ovih đubriva. Cilj ovog rada bila je analiza kvaliteta rada centrifugalnih aparata u kontekstu fizičko-mehaničkih osobina primenjenih đubriva. Ispitivanjem su obuhvaćena dva rasipača centrifugalnog tipa tokom predsetvene pripreme za setvu kukuruza.
