Aditivos incorporados à ureia para reduzir perdas de nitrogênio após aplicação ao solo

N-NH 3 Daily Volatilization Rate (DVR) (a) and N-NH 3 Accumulated Volatilization Rate (AVR) (b) based on the treatments applied in the second side-dressing fertilization, 52

The purpose of this study was to compare the influence of urea coated with sulfur or with boric acid and copper sulfate, and of conventional nitrogen fertilizers on nitrogen losses

We evaluated urea-based N fertilizers treated with coating technologies, i.e., coating with boric acid and copper sulfate - UCuB (N = 44.6 %, B = 0.39 % and Cu = 0.16 %) and

The highest volatilization peak was observed from slow-release fertilizer, one day after fertilization, followed by urea, 2 days after fertilization, and urea with urease

For the sulfur coated urea coated and for prilled urea incorporated at 0.02 m depth, the maximum daily N-NH 3 loss was on the Figure 4: Climatic data (A) and daily

Nitrate upward (capillary rise) and downward (leaching) movements are higher when NBPT-treated urea is used, compared with conventional urea, which demonstrates greater mobility
