Nitrogenous fertiliser soln. contg. trace elements - with dicyandiamide added for improved solubility and stability

摘要

A fertiliser soln. contg. micronutrients is based on N cpds. and can also opt. contain phosphates and/or K salts. The new feature is that the soln. additionally contains dicyandiamide (I). Pref. the N content of (I) in dissolved form is 10 wt. % of the total N content of the remaining N cpds.. Addition of (I) increases the solubility of the trace elements; stabilises the soln. even at low temp. (partic. this stabilisation is noted for Fe2+ and Mn2+ salts) and reduces the corrosive nature of the soln.. The solns. can be presented as concentrates e.g. in small packages.
