Carriers are disclosed for supporting a plurality of agricultural cores on a plurality of core supports for coating by a flexible film. The plurality of core supports may include a pedestal for supporting a respective agricultural core and a core periphery region having a plurality of bridge elements which couple the pedestal to the connecting structure between the plurality of core supports. The carriers may include a vacuum system that independently communicates a partial vacuum to an aperture in each respective pedestal and a plurality of apertures in the core periphery region of a respective core support between the bridge elements.

The disclosed composition for fertilization and treating trees, shrubs and climbing plants with programmed release of the active substance is comprising the active substance stored in capsules made by nanoencapsulation or microencapsulation method and wherein based on capsule membrane the time of release of the active substance is adjusted. The active component stored in the nanocapsules or microcapsules can be such that it acidifies the surrounding soil in the range of pH 2,5 to pH 6,5. One example of such active component is the use of citric acid, which is completely ecological and does not create environmental pollution. Also, the active component in the nanocapsules can be such that it regulates the acidity of the soil in the range of pH 6,5 to pH 7,0. Furthermore, the active component in the special capsules can be an insecticide and/or in the special capsules fungicide, and/or in the special capsules acaricide and/or in the special capsules pheromone and/or in the special capsules repellent.

Fertilizer particles containing a core and a shell is described. The core can contain urea, a pH buffering agent, and an urease inhibitor, and the shell can contain urea and can cover at least a portion of an outer surface of the core. The core can include 20 wt. % to 80 wt. % urea, based on the total weight of the core, and the shell can include 50 wt. % to 100 wt. % urea, based on the total weight of the core.

A system and method are provided for manufacturing the polymer-coated fertilizers with a controlled release in a single pass. The system has a feeding mechanism connected to a first chill roll to supply the articles to the first cavities provided on the first roll to store and hold the articles. A first machine produces and applies a first polymer film on the articles held in the first chill roll to coat the articles partially with the first polymer film. The partially coated articles are transferred to a second chill roll placed at a side or on a top of the first chill roll. A second machine produces and applies the second polymer film on the partially coated articles in the second chill roll so that the articles are encapsulated by the first and second polymer films. A collector mechanism receives the encapsulated articles from the second chill roll.
