The two areas are 50 km apart.\nIn the animal husbandry district pig breeding farms are very common. They are very intensive with high meat productivity; they produce mostly liquid manure and supplies the highest amount of manure (266 kg N ha-1) to crops, maize for grain production and to poplar trees (Bassanino, 2007). A large number of pig breeding farms are on area included in the Nitrate Vulnerable Zones (NVZ) where the nitrogen (N) from animal manure allowed to be distributed on field does not exceed 170 kg ha-1 stated by local regulation enforcing Nitrates Directive (91/676/EEC). Here breeding farms do not have enough crop surface to spread manure with respect the limit set by the regulation (Cavallo, 2004), thus they have a surplus of N. In order to solve this excess of N liquid manure pig breeding farms adopt different strategies. One of them is the separation of the high dry-matter and nutrient-rich solid fraction (SF) from the liquid manure. The solids could be cost-effectively transported to short and medium distance for off-farm users.\nVine and hazelnut are cultivated on area that have the maximum erosion threat and low (>1%) organic matter (OM) content (IPLA, 2007; IPLA 2006). This is due to the texture of the soil, the steep slope, the intensive cultivations of vines and hazelnuts, maintaining the soil bare with continuous tillage, and the lack of manure to be use for organic fertilization. (Regione Piemonte, 2007). Vineyards are the lands that incur the highest runoff and soil losses (Ramos, 2004). Application of cattle manure or organic material with similar characteristics, could improve the physical properties of soil, such as soil porosity, structure and water holding capacity, beneficial for soils susceptible to erosion, and could be important sources of nutrients (N and P) and other elements, reducing fertilisation costs (Ramos 2006).\nThe farms growing vine and hazelnut rarely supply the crops with organic manure from animal dejections, because of the cost of the material and the difficulties to find it. Most of the livestock farms in this area had stopped activities since at least 2 decades.\nThe paper reports about a demonstration action - funded by the local administration - involving farms from these 2 areas carried out in order to show that the SF separated from pig slurry, rich in organic nitrogen and organic matter, could be transported and spread as organic fertilizer and source of organic carbon in vineyards and hazelnut cultivations."@en . @prefix ns9: . prodotto:ID84939 pubblicazioni:editore ns9:ID4974 ; prodottidellaricerca:prodottoDi istituto:CDS049 . @prefix modulo: . prodotto:ID84939 prodottidellaricerca:prodottoDi modulo:ID2479 . @prefix unitaDiPersonaleInterno: . prodotto:ID84939 pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA1947 . @prefix parolechiave: . prodotto:ID84939 parolechiave:insiemeDiParoleChiave . unitaDiPersonaleInterno:MATRICOLA1947 pubblicazioni:autoreCNRDi prodotto:ID84939 . modulo:ID2479 prodottidellaricerca:prodotto prodotto:ID84939 . ns9:ID4974 pubblicazioni:editoreDi prodotto:ID84939 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID84939 .
