“…The decrease in contents after 20 DAS can be due to leaching losses, favored by high rainfall in the period (Figure 1). Although the use of slow-release fertilizers may delay urea hydrolysis and, consequently, the nitrification process, it is not efficient in reducing leaching losses accumulated for a certain a period (Dal Molin et al, 2018). Figure 2 -N-NO3soil contents (mg kg -1 ) according to nitrogen sources and application: T1 -control; T2conventional urea in total dose at sowing; T3conventional urea split (sowing and topdressing); T4slow release urea in total dose at sowing; T5slow release urea split (sowing and topdressing).…”

“…Similarly, single SRU application at sowing also resulted in a lower N use efficiency by the plants when compared to split SRU application. Despite reducing ammonia volatilization losses (Nascimento et al, 2013), frequent rains may increase leaching losses (Martins et al, 2014;Dal Molin et al, 2018). This may have been one of the factors that led to such results.…”

Urea is the nitrogen fertilizer most used in agriculture and the most subject to N losses. Thus, it is important to look for alternatives to reduce these losses and increase agronomic N use efficiency. In this sense, this study evaluates the effect of split or single application of slow-release and conventional urea in maize development and yield, as well as the fertilizer use efficiency by plants. The experiment was carried out in Santa Rosa do Sul-SC, in a randomized complete block design with 5 treatments and 3 replicates. The treatments evaluated were: control; 100% of the recommended dose of conventional urea at sowing; 30% of the recommended dose of conventional urea at sowing and 70% at topdressing; 100% of the recommended dose of slow-release urea at sowing; 30% of the recommended dose of slow-release urea at sowing and 70% at topdressing. The variables analyzed were ear insertion height, stem diameter, leaf chlorophyll content (R1 stage), yield components, crop yield, and nitrogen use efficiency. The split application of slow-release urea to the soil positively affected stem diameter and nitrogen use efficiency in maize plants, being, therefore, a good fertilization alternative for the crop in the soil and climate conditions of the region.

“…Leaching is one of the main factors that results in water and nutrient loss in soil and is also a major cause of environmental water pollution [37][38][39]. Compared with ρ 0 , muddy water infiltration reduced the leaching solution volume, and the leaching solution volume decreased with the increase in sediment concentration.…”

This study analyzes the soil water infiltration characteristics under muddy water irrigation and bio-organic fertilizer conditions in the current context of muddy water irrigation rarely being used in agricultural production and in combination with the problems of water resource shortages and low soil fertility in arid and semi-arid regions. An indoor one-dimensional soil column infiltration device was used for studying the effects of four muddy water sediment concentration levels (ρ0: 0; ρ1: 4%; ρ2: 8%; ρ3: 12%) and four bio-organic fertilizer levels (FO0: 0; FO1: 2250 kg·hm−2; FO2: 4500 kg·hm−2; sFO3: 6750 kg·hm−2) on soil water infiltration, evaporation characteristics, and leaching loss. The results demonstrated that a higher muddy water sediment concentration and fertilization level resulted in a smaller wetting front distance and cumulative infiltration amount within the same time, but the infiltration reduction rate (η) gradually increased. The three infiltration models (Kostiakov, Philip, and Horton) were fitted, and it was discovered that all three had good fitting results (R2 > 0.8), with the Kostiakov model displaying the best fit and the Horton model exhibiting the worst fit. The cumulative evaporation amount and evaporation time in muddy water irrigation and fertilization conditions was consistent with the Black and Rose evaporation models (R2 > 0.9), the Black model was proved to be higher than the Rose model. In comparison to ρ0, muddy water irrigation increased conductivity and total dissolved solids (TDS) in the leaching solution, but it reduced cumulative evaporation, soil moisture content, the uniformity coefficient of soil water distribution, and leaching solution volume. Compared with FO0, the application of bio-organic fertilizer increased soil water content and reduced soil water evaporation while also reducing the leaching solution volume, conductivity, and TDS in the leaching solution. The results of this research can provide scientific reference for the efficient utilization of muddy water irrigation and the rational application of bio-organic fertilizer.

“…Nitric fertilizers generally have higher N losses from soil leaching, 21 but here this does not appear to have occurred. Dalmolin et al 22 also found reduced N losses from leaching when ammonium nitrate was used compared to urea. In this case, the authors attributed this difference to the more intense denitrification process when the nitrogen source was ammonium nitrate, since there is no need for previous transformation of amidic N into ammonium and then nitrate.…”
