To the farmer – utilisation of organic matter (compost)
The model utilised a pellet compost product that was poured with a 5 Kg/mq dose mixed to the soil through a 15 cm harrowing. This demonstrated to be effective in enriching the soil with organic matter.
Compost is classified by the Italian law as
“Green composted soil amendment” if obtained exclusively
by vegetal by-products and as “Mixed composted soil amendment”
if obtained by the composting of vegetal by-products mixed to
biomasses of different origin (organic fraction of urban waste,
market waste; agro-industry waste; husbandry waste, etc…).
To be effective the mulching has to cover at least 95% of the field, and this signify to input frequently more than 200 t/ha-1. Its use therefore depends on the availability and on the price.
Moreover quality of compost it is important
and therefore will be utilised only quality compost according
to the standards fixed by the Italian laws D.L. 22/97 and 748/84.
