Mulching, when and why it can be used
Mulching is an ancient technique that, yesterday as today, offers significant advantages. In addition to its best-known function, which is to block the development of weeds by preventing solar radiation from reaching them, mulching performs or can also perform other functions that, in certain situations, become principal.
FERRARI explains that, in fact, its use interferes with many physical, chemical and biological parameters of the soil, with the development of the crop and of some parasites and pathogens.
Modern mulching involves the use of coherent films, of plastic origin or of biological origin and, in this case, they are biodegradable. The film’s degradation time depends on both, the film material and the fertility/microbial load of the soil. The bio-degradable ones offer the undeniable advantage of avoiding collection at the end of the cycle and improving the sustainability of the production process.
The action performed by these films can vary according to the behaviour shown in relation to light and gas permeability. On the other hand, quality is also influenced by mechanical characteristics: tensile, tear, impact and elongation resistance.
Different machines are available for the mulching and transplanting.
