Synthesis and application of urea and furfural condensation product on maize crop
Main Article Content
Abstract
out in an acid medium using absolute ethanol as solvent. 13C
HMR 1H and IR spectroscopy showed that the only product
obtained, independently of the initial molar ratio of urea-furfural
used, is difurfurilidentriurea (DFTU). Three treatments in maize
culture were applied with DFTU (25 % of nitrogen): 100, 80
and 60 kg.ha-1, one with urea (120 kg.ha-1, 46 % of nitrogen)
and a test. Significant differences among treatments are not
observed in the traditional growth parameters, even in the one
where urea was applied that has a bigger nitrogen percentage
compared with DFTU. The application of DFTU has a positive
influence on the determined soil properties.
