FERTILCEREAL 21 DCD is a simple liquid nitrogen fertilizer in which the function of the nutrient nitrogen (urea and ammonia) has been linked to DICIANDIAMMIDE so as to achieve positive economic and environmental management advantages of this macronutrient relative to biological transformation processes. Thanks to the inhibitor DICIANDIAMMIDE, ammoniacal nitrogen is converted to nitrate nitrogen in a period of 8 to 12 weeks by reducing the traditional nitrogen supply.The inhibitory activity of DICIANDIAMMIDE against urease and nitrifying bacteria is manifested in a reduction of losses by leaching and volatilization. The inhibitory action of DICIANDIAMMIDE, exhibits absolute invariance with respect to environmental conditions, and this, together with ease of use, makes FERTILCEREAL 21 DCD a decidedly attractive product compared to other similar compounds, in that the distributed nitrogen is completely absorbed by the affected crop.FERTILCEREAL 21 DCD is a product designed specifically for effective use in spring nitrogen fertilizations (COLZA, MAIS, STRAW CEREALS) carried out in conjunction with weed control or fungicide and insecticide treatments, in hose and/or with the down
