Rokolan is a basic fertilizer on an organic basis intended for root nutrition of agricultural crops. Its effect ensures a better start in the initial phase of growth due to better development of the root system and the starting dose of nutrients with a high content of amino acids. The effect of Rokolan is a mix of eighteen types of amino acids, different types of peptides, excipients and nutrients needed for the purpose of application. Contains organic nitrogen from chicken feathers. The goal of Rokolan is to support plant growth, strengthen plant resistance to pests, diseases and stress conditions. The amino acids in the fertilizer, on the one hand, directly nourish the plants and at the same time provide nutrition to the microorganisms, thus activating the soil microflora and subsequent mineralization processes. Rokolan effectively supports the efficient use of nutrients found in the soil and thus reduces the demands of plants on the amount of fertilizers used.
