The effects of a controlled release urea (CRU) on concentration N in root zones, activities metabolism enzymes leaves, and use efficiency rice ( Oryza sativa L.) grown silt loam soil lysimeters were investigated. entire amount (100–300 kg ha −1 ) the CRU was incorporated into plug for growing seedlings while regular split three applications (the standard practice). Results indicated that closely matched requirements rice, commingling with seeds increased within zone enhanced glutamine...
In this paper, we synthesized a biobased polyurethane using liquefied corn stover, isocyanate, and diethylenetriamine. The was used as coating material to control nitrogen (N) release from polymer-coated urea. A novel superabsorbent composite also formulated chicken feather protein (CFP), acrylic acid, N,N'-methylenebisacrylamide an outer for water retention. We studied the N characteristics water-retention capability of double-layer urea (DPCU) applied in both soils. ear yields, dry matter...
Polymer-coated urea (PCU) has great potential for increasing crop production and enhancing nitrogen (N) fertilizer use efficiency, benefiting the ecosystem. However, current PCUs are used only in a limited market, main obstacle to wider of is high cost compared that conventional N fertilizers. In this study, low PCU large tablet polymer-coated (LTPCU) were prepared by using recycling polystyrene foam various sealants as coating materials. The structural chemical characteristics shells coated...
The effects of newly developed controlled release urea (CRU) and its placement method on the N use efficiency nutritional quality winter wheat ( Triticum aestivum L.) grown a loam soil were investigated during 2 yr. was soil. CRU applied at 0, 75, 150, 225 kg ha −1 with seeds sowing while treatment split into two applications: two‐thirds one‐third 5‐tiller stage (Z25). Results showed that rates fit requirements improved wheat's apparent uptake by 28.5% compared to treatment. Although 150 had...
A novel polymer-coated nitrogen (N) fertilizer was developed using bio-based polyurethane (PU) derived from liquefied locust sawdust as the coating material. The PU successfully coated on surface of urea prills to form (PCU) for controlled N release. Epoxy resin (EP) also used further modify synthesize interpenetrating network (IPN), enhancing slow-release properties PCU. release characteristics EP-modified PCU (EMPCU) in water were determine at 25 °C and compared that EP-coated (ECU)....
Although commercialized slow-release fertilizers coated with petrochemical polymers have revolutionarily promoted agricultural production, more research should be devoted to developing superhydrophobic biopolymer coatings superb ability from sustainable and ecofriendly biomaterials. To inform the development of biopolymer-coated (SBSF), mechanism SBSF needs clarified. Here, superior performance, water tolerance, good feasibility for large-scale production was self-assembly fabricated using a...
The development of efficient biobased controlled-release fertilizers has captured much research attention because the environmental concerns and food scarcity problems. In this work, a biomimetic superhydrophobic polyurethane-coated fertilizer (SBPF) was successfully fabricated by increasing surface roughness reducing energy polyurethane (PU) coating. green PU coating synthesized from low-cost, biodegradable, renewable cottonseed oil. nutrient release longevity SBPF revealed 2-fold...
Although bio-materials for controlled-release fertilizers (CRFs) have been developed rapidly because of their low-cost and green sustainable properties, the release characteristics these CRFs still face problems coating is often hydrophilic with many micro-holes.
Novel biobased polyurethane (PU) was synthesized by using waste frying oil-based polyol (WFOP) and isocyanate for slow-release fertilizers (SRFs). Epoxy resin (EP) used to modify PU synthesize the interpenetrating network (IPN) improving properties of coating film. Nine polymer-coated nitrogen (N) were prepared from these composite materials. The N release characteristics PU-coated urea (PCU) in water soil determined. Degradation behavior coatings evaluated. Results showed that 20% EP...
Because of its strong pollutant degradation ability, nanoscale zerovalent iron (NZVI) has been introduced to soils and groundwater for remediation purposes, but impacts on plants are still not very clear. In this work, the effects low concentration (10–320 μmol/L) NZVI particles seed germination growth peanut were evaluated. The exposure seeds at all tested concentrations altered activity, especially development seedlings. comparison with deionized water treated controls (CK), treatments had...
Nitrogen fertilizer is important for improving wheat ( Triticum aestivum L.) and corn Zea mays yields, but inappropriate application methods excessive amounts lead to low N use efficiency high losses through leaching. To investigate the effects of controlled‐release urea (CRU) on crop yield soil fertility, a field experiment was conducted from 2012 2014 in China. The 100% (180 kg ha −1 ) 70% (126 local practice rates with CRU were used. results revealed that release curves natural...
Bio-based slow-release fertilizers (SRFs) have drawn significant attention because their applications for crop production can improve nutrient utilization efficiency as well prevent environmental pollution. However, current commercial SRFs still exhibit uncontrollable release patterns, use a large quantity of synthetic coating materials, and are unable to adapt complex soil conditions (e.g., arid soil). In this study, double-layer SRF was formulated from low-cost lignin–clay nanohybrid...
Self-healing materials have received increased attention because of their automatic detecting and repairing damage function. In this paper, a novel self-assembly self-healing bionanocomposite was developed as coating material for controlled release fertilizers. This nanotechnology-enabled is environmentally friendly highly efficient possesses tunable nutrient-releasing characteristic. the synthesis process, bio-based polyurethane coated urea (BPCU) prepared by reaction bio-polyols with...
To improve nitrogen (N) use efficiency and minimize environmental pollution caused by fertilizer overuse, novel bio-based large tablet controlled-release urea (LTCRU) was prepared using coating materials to coat (LTU) derived from prills (U). Nano fumed silica (NFS) added the slow-release properties. The surface area of LTU U measured three-dimensional scanning. In comparison U, had a smaller area/weight ratio, which can reduce materials. Scanning electron microscopy analysis showed that...
