“…On the other hand, the permeability values reported were lower than those obtained by Ma 44 , who developed different agricultural mulches on the basis of the waste from the fermentation industry, so that the starch-based films developed would offer a greater capacity for water retention. However, the starch, being a hydrophilic polymer, has a WVP relatively higher than that of the PE, so that the maintenance of humidity is relatively lower.…”

In order to evaluate the potentiality of novel formulations based on starch to be used as agricultural mulch films, native and oxidized corn starch nanocomposites were prepared by extrusion using natural (Bent) and chitosan-modified bentonite (Bent-CS) fillers. The nanocomposite interactions with water were studied by means of moisture content (MC) determination, water solubility (WS), water vapor permeability (WVP), and contact angle (CA). The light transmission spectra were analyzed in order to determine the transparency and radiometric properties of films. Mechanical properties are also included and related with the cryo-fractured surface morphology observed by scanning electron microscopy (SEM). Finally, the antimicrobial action of developed nanocomposites was investigated against the phytopathogen bacterium Pseudomonas syringae pv tomato DC3000 (Psy). Results suggest that starch oxidation leads to a reduction in polarity and transparency. The incorporation of nanoclays improved water resistance but did not produce a significant effect in WVP and mechanical properties, and new strategies are required to improve the nanocomposite performance. However, the incorporation of Bent-CS exerted antibacterial activity on nanocomposites, which is an encouraging result.

“…The release of P from the polymer-coated fertilizer when in contact with the soil may also be influenced by the biodegradability of the polymer (Ao et al, 2013;Lubkowski et al, 2015) and by the characteristics of the soil solution surrounding the granule (ionic strength; temperature; pH conditions) (Hanafi et al, 2000;Tyliszczak et al, 2009;Ahmad et al, 2015). This fact contributes to the delayed release of the coated P fertilizers.…”

“…Among these slow-release fertilizers (SRF), the major categories are fertilizers coated with different materials. Recently, a number of materials have been tested: biodegradable polymers (Wu and Liu, 2008;Ao et al, 2013;Jia et al, 2013;Lubkowski et al, 2015), superabsorbent polymers (Liang et al, 2007;Teodorescu et al, 2009), commercial polymers (Figueiredo et al, 2012;Silva et al, 2012;Ma et al, 2013), oxides (Zhang et al, 2014) and fly ash (Dong et al, 2016). More specifically for MAP, a previous study has shown that when P is more slowly released from a thin polymer coated-MAP fertilizer granule, it increased P availability, P uptake and P use efficiency by barley plants (Pauly et al, 2002).…”

In this paper, we report the results of studies on the solubility (water solubility trial) and the response by plants (greenhouse pot experiment using Zea mays) for four types of monoammonium phosphate fertilizers (Conventional MAP -MAP 1 , MAP coated with a natural organic acid -MAP 2 , MAP coated with a synthetic organic acid -MAP 3 , and MAP coated with a peat humic organic acid -MAP 4 ) applied at five increasing doses (0, 100, 300, 600 and 1200 mg P dm -3 ) and pre-incubated with the soil for five lengths of time before planting (0, 15, 30 and 60 d). The coating with organic acids reduced the water solubility of the P fertilizers -MAP 4 provided a more gradual release of P over time. In the soil pot experiment, it was found that MAP 1 required the highest dose to reach 90% of dry matter accumulation by the maize plant, followed by the Coated-Slow-Release Fertilizers (CSRF). The agronomic efficiency (AE) of P applied as the CSRF was 3 to 13% greater than that of MAP 1 . In addition, MAP 4 led to higher values of AE (+11%) and apparent P recovery by maize (+41%) in comparison to MAP 1 . The physicochemical properties imposed by the chemical composition of the organic acid coatings generated fertilizers with distinct release rates and improved agronomic efficiencies.

“…In addition, the maximum biodegradation rate reached about 80%, which indicated that the biodegradability of the composite will not change when absorbing dust. Thus, we concluded that the OCS‐Gel composites before and after absorbing dust have good biodegradability, which can avoid secondary pollution.…”

Degraded gelatin (Gel) and oxidized corn starch (OCS) as renewable and abundant recyclable and biodegradable materials can be applied to dust mitigation, which has been investigated in this research. Blends of oxidized corn starch and gelatin (OCS-Gel) were prepared by introducing the OCS into the Gel. Sodium carboxymethyl cellulose was used as a thickener and dispersant in the blends. The OCS-Gel blends were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis (TGA). The results revealed that the blends have a uniform porous structure and can form stable Schiff's base structures. The TGA and DTGA thermograms indicated high thermal stability up to 325 8C. Moreover, the blend had good stability and compatibility by mixing with an electrolyte solution, and the biodegradability and water-sorption measurements also revealed that the OCS-Gel had excellent hygroscopicity and degradability. The results of contact angle measurements between OCS-Gel solutions and dust showed that the blends have a satisfactory effect on dust wetting, and the results of light-transmittance tests revealed that the blends had a good effect on dust-removal ability. In addition, the dust particles can be evenly adsorbed on the surface of OCS-Gel when they were evenly dispersed on the surface of the OCS-Gel solution and can then form a film. The simulation experiment for flying dust in an enclosed area indoors indicated that the dust-suppression degree for particulate matter less than 2.5 micrometers (PM 2.5 ) and less than 10 micrometers (PM 10 ) in size can reach 68.2% and 78.7%, respectively.
