The notable advantage of the use of plastic mulch is its impermeability, which prevents direct evaporation of moisture from the soil and thus cuts down the water losses.3 Plastic such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE) has been used as plastic mulch. Among these types of plastics, LDPE mulch is most commonly used. Recently, LLDPE has been scoring over LDPE as a mulch material due to its two associated characteristics of better down gauging and puncture resistance, and checks weeds growth.

Of increasing environmental concern is, in addition, the growing use of petro-based plastics in agriculture (e.g. plastic mulch) along with other plastic pollutants (e.g. food packaging), with impacts far from being effectively quantifiable. On top of potentially being capable of inducing impacts in living organism outside arable areas, these plastic pollutants increase soil erosion, reduce water holding capacity, and impact soil biological metabolisms and diversity as well as the organic matter composition and stability of arable soils (Steinmetz et al., 2016). Moreover, leaching of these harmful chemicals into ground water is of particular concern. The presence of micro and nano-plastics in aquatic, terrestrial and marine habitats has been reported (Chae and An, 2017). The potential of these particles to cause harm to human health remains understudied and unquantified. The production and extended use of chemicals (e.g. agro-chemicals) and biodegradable materials (e.g. PHA, lignocellulosic composites), relying on agricultural residue resources, can on the other hand have a significant impact on the substitution of the potentially harmful petro-based plastics in soils (e.g. Costa et al., 2014) and on the micro and nano-particle concentrations in groundwater (Galloway, 2015). The production and consumption of plastic materials in agriculture and in general has rapidly increased since the 1970s. Degradation of conventional petro-based plastics in the environment is estimated to range from 50 up to hundreds or even thousands of years (Zalasiewicz et al., 2016), indicating that conventional environmental impact assessment methods are insufficient to address micro and nano-particle contamination issues, since these methods do not take into account long (i.e. century long) term effects such as those induced by plastic micro and nano particles.
