The paper presents studies about the process of obtaining the fertilizers based on ammonium phosphates (NH 4 ) 2 HPO 4 and NH 4 H 2 PO 4 with boron added as micronutrient. As boron source was used boric acid, which has been introduced into the neutralization mass at various NH 3 :H 3 PO 4 molar ratio, in order to obtain thermal stable compounds, with a minimum loss of nutritional elements (N, P). The variation of pH, considered the process control parameter, as a function of NH 3 :H 3 PO 4 molar ratio was recorded during the neutralization.Specific analyses has been used in order to determine phosphorus, ammonia nitrogen and boron content in the obtained fertilizers. The thermal behaviour of the fertilizers was studied using TG and DTG. The lowest total mass loss was observed at a 1.5 NH 3 :H 3 PO 4 molar ratio.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
