“…All mulching types reduced the soil temperature fluctuation as compared to bare soil, due to minimum soil temperature increase, as also described by Moreno et al [30]. Consistently with our plant growth and yield results, other authors [18] reported the positive effect of increasing soil temperature under mulching on peanut leaf area index and pod production compared with the bare soil. The 15% starch-based biodegradable film warmed the soil up with similar effectiveness as PE film in the first two months of peanut cultivation, thereafter the soil temperature under the biodegradable mulch was 0.8-2.8 • C lower compared to PE at 10 cm soil depth.…”

“…In this respect, the films can break down too slowly, resulting in problems with persistent small fragments of residual mulch, or too quickly, leaving the crop unprotected [17]. The economic benefit connected to the use of biodegradable mulch may be slightly lower than the plastic one due to the higher current cost of biodegradable films [18], which however do not need to be removed from the soil. Mater-Bi is a starch-based biopolymer which is similar to traditional plastic in terms of agronomic characteristics and to cellulose referring to degradation rate [19].…”

The plastic mulch has raised a disposal issue, which has been diverting the research focus on biodegradable film as an alternative. Research was carried out in southern Italy in 2016–2017 and 2017–2018 in order to assess the effects of three crop cycles (autumn-winter, winter, spring) in factorial combination with three soil mulching types (a MaterBi biodegradable black film; a brown photoselective low density polyethylene (LDPE) film; a black-standard LDPE film) and a non-mulched control, on leaves yield, quality and antioxidants of greenhouse grown Diplotaxis tenuifolia (L.) D.C. The spring cycle was the shortest and best enhanced plant growth and yield. The non-mulched control caused an 11% yield reduction compared to the mulching treatments average (12.4 t ha−1). The soil temperature was highest under photoselective and standard LDPE films. The Soil Plant Analysis Development (SPAD) index was 17.4% higher in the leaves grown in mulched soil. Winter season and biodegradable mulch led to higher leaf dry residue and organic acids. Leaf nitrate content was highest in winter and under mulching. The spring cycle, the biodegradable and photoselective LDPE film resulted in the highest antioxidant compound content and activity. The biodegradable polymer improved leaf quality, showing suitable features for sustainable production.

“…The duration of degradation film's warming effect is also related to crop species. Sun et al [38] showed that the soil temperature in a field with peanut crop that had been treated with biodegradable film was significantly higher than that with non-mulching treatment during the entire growth period, mainly because the peanut canopy was small and the film could absorb solar radiation directly. However, different conclusions have been drawn in tall-stem crops, such as maize.…”

Plastic film is an important resource in agricultural production, but it takes hundreds of years to degrade completely in natural environment. The large-scale use of plastic film will inevitably lead to serious environmental pollution. One way to solve the problem is to develop a substitutable mulching film, such as a biodegradable film that can ultimately be decomposed to water, carbon dioxide, and soil organic matter by microorganisms. In this study, a 2-year experiment was conducted to determine the degradation properties of a biodegradable plastic film, including degradation rate, surface microstructure, tensile strength and elongation at break, and the effects of different mulching treatments on soil temperature and maize yield. The mulching experiment was conducted with three different biodegradable plastic films with different degradation rates, using a common plastic film and a non-mulched treatment as control. With the addition of the additives for degradation in the biodegradable plastic films, the degradation rates increased significantly, which were 7.2%-17.8% in 2017 and 18.1%-35.2% in 2018 after maize harvesting. However, the degradation occurred mainly on the ridge side. The decrease in tensile strength and elongation was proportional to the degradation rate of the degradable film. The SEM results indicated that the surface microstructures of the biodegradable films were loose and heterogeneous after maize harvesting. Biodegradable plastic film mulching increased the soil temperature at soil depths of 5 cm, 15 cm, and 25 cm, over the maize's entire growth period, by 3.1°C-3.2°C in 2017 and 1.2°C-2.1°C in 2018 compared with the non-mulched treatment. The biodegradable plastic film increased the maize yield by 10.4%-14.3% in 2017 and 11.6%-24.7% in 2018. The soil temperature and maize yield increases were statistically significant; however, with respect to maize qualities, there were no statistically significant increases among the five treatments. This study shows that biodegradable plastic film can be used as a substitute for common plastic film. However, the ingredients in biodegradable plastic films should be improved further to ensure that they can be degraded completely after crop harvest.

“…The peanuts were planted in May 2013 and April 2014, and harvested in September 2013 and September 2014, respectively. The authors observed that the 150 g kg −1 starch film presented similar results to the polyethylene film for the entire growing season . Cassava starch films and poly(butylene) adipate‐co‐terephthalate blends were developed for use as a cover film in the production of strawberries.…”

BACKGROUND The technological advances in agriculture, driven by the increased demand for food attributed to population growth, have led to the search for technologies that allow greater control over the variables that interfere in crop yield. Several techniques stand out for optimizing yield capacity, including cultivation in a protected environment, mulching and low tunneling. To expand the use of these techniques, synthetic petroleum‐based polymers are employed due to their low cost, easy processing, and lightness. However, they take a long time to degrade, and, since they are discarded at the end of each cycle of cultivation, end up accumulating in the environment causing irreversible damage. RESULTS The use of biodegradable films, made of starch and/or a protein source such as gelatin, has been studied as a promising alternative. Both stand out because of their film‐forming ability, and because they come from abundant sources and are biodegradable. CONCLUSION This study aimed to review the current findings on starch and gelatin films that can be used as alternatives to conventional plastics in agricultural crops. © 2019 Society of Chemical Industry
