Agronomic evaluation of polymer-coated urea and urease and nitrification inhibitors for cotton production under drip-fertigation in a dry climate

Abstract: Interest in the use of enhanced-efficiency nitrogen (N) fertilizers (EENFs) has increased in recent years due to their potential to increase crop yield and reduce environmental N loss. Drip-fertigation is widely used for crop production in arid regions to improve water and nutrient use efficiency whereas the effectiveness of EENFs with drip irrigation remains unclear. A field experiment was conducted in 2015 and 2016 to examine the effects of EENFs on yield, N use and quality of cotton (Gossypium hirsutum) gro… Show more

“…Urease inhibitors slow urea hydrolysis in soil by lowering NO 3 – and NH 4 + production. In addition, the presence of the inhibitor in the soil influences the effectiveness of NH 3 loss management [ 22 , 23 ]. Concerning nitrification inhibitors, these have a significant impact on the enzymatic activity of NH 3 oxidizing bacteria [ 24 ] and their addition to urea delays the conversion of ammonium ions (NH 4 + ) to NO 3 – NO 3 , potentially reducing N 2 O emissions from soil denitrification [ 25 ].…”

“…For example, urea has been impregnated with chemical additives such as N-(n-butyl) thiophosphoric triamide (NBPT) [4][5][6][7] and several polymers with different principles of action [8,9]. Moreover, chemical inhibitors include urease inhibitors [10] that hinder the hydrolysis of urea by urease enzyme, and nitrification inhibitors [11] that prevent the oxidation of NH 4 + have also been used as coating materials [12]. Organic or inorganic compounds [13][14][15][16][17][18], and micronutrients [19,20] are used for coating urea.…”
