The mulching operation is implemented in agriculture and gardening is done by covering the soil with a layer of material, in order to prevent the growth weeds, keep moisture in the soil, protect the soil from erosion, prevent the formation of so-called crust, reduce compaction, maintain the structure and raise soil temperature.
Materials
- cocoa husks
-
straw - dried leaves
- grass mowing
- shredded pine bark
- Cardboard
- litter
- plastic film or bioplastic
- gravel
- lapillus
eg.: shredded bark
Mulching imitates what happens naturally in the woods where the leaves are piling up on the ground under the tree, limiting the growth of other vegetation.
The effect is due to inhibition of a physical (and preventing the penetration of sunlight, lack of space for the development of weeds) and biochemical actions of (the release of inhibitory substances that contaminate the bio- seeds and propagating parts of weeds).
This technique allows to maintain the level of surface roots, a higher temperature in the cold months, while decreasing the need for watering during the warm months.
Mulching is a method widely used in sustainable agricultural practices such as permaculture, natural farming and biodynamic farming.
With regard to the recent problems related to the spread of the tiger mosquito in Italy, it should also be noted that the technique of mulching, now widespread in thousands of private and public gardens, create as many receptacles for the development of the larvae which Contrary to popular view, are developed not only in stagnant water in the soil but, when wet, and do not proliferate in random spots and low vegetation and shaded.
A technique very suitable for the benefits it gives the care of the vegetation today thus involves a problematic side of the coin on which is worth some reflection.
