“…This outcome of compost on soil organic matter increase and stabilization could be particularly useful in Mediterranean areas, where the climatic conditions generally induce high mineralization. In our research, the observed effects of composted organic materials on SOC changes further confirm findings of other studies (Kukal et al 2009;Diacono et al 2012). Conversely, the DA repeated applications reduced the SOC content, thus contributing in the long term to both an atmospheric enrichment in CO 2 concentration and a reduction in soil fertility.…”

“…The total N and P contents of the four experimental composts were quite different, suggesting that the composition of starting materials may be responsible for the nutrient contents of amendments, as reported in detail by Diacono et al (2012). The pH of the composts was in the range allowed by Italian fertilizers legislation, which is 6-8.5 (Decree n. 75 2010).…”

“…Olive pomace, which is one of the most important organic agro-industrial wastes in Mediterranean countries, contains a large proportion of organic matter that could profitably be recycled (Diacono et al 2012). Altieri and Esposito (2010) indicated that composting is recognized as an environment-friendly and economically viable technology for managing organic waste such as olive mill wastes.…”

An inadequate replacement of organic matter in agricultural lands progressively leads to soil fertility reduction and therefore, soil application of organic fertilizers and amendments should be promoted. The objectives of this 3-year research project on organic lettuce were to investigate the agronomic performance of experimental organic amendments obtained by using agro-industrial wastes in comparison with a commercial organic fertilizer, and to evaluate their short-term effects on soil mineral-N and soil organic carbon changes. Two types of olive pomace mixtures, with different initial C/N ratios, were composted and either stopped at the active phase (A1 and B1) or processed until maturation (A2 and B2). Also an anaerobic digestate (DA) and the B2 in combination with mineral fertilizer (B2-MIN) were studied. The four composts, DA and B2-MIN were compared with a commercial organic fertilizer (Org), and an unfertilized control (N0). Results suggested that the best compromise for organic lettuce yield and soil fertility could be obtained with the B2 compost, thus highlighting the need for choosing a good stage of maturity of the compost, along with an appropriate C/N ratio of composting mixture, to improve the fertilizing efficiency of agro-food residues in organic farming. Furthermore, the application of immature amendments did not increase (B1) or significantly reduce (A1) marketable lettuce yield, indicating that the choice of organic fertilizer is an important concern in sustainable agriculture, especially in organic vegetable production.

“…In Italy, a research study was carried out to evaluate the influence of olive pomace compost [fertilization treatments (each of them at a rate 80 kg N ha -1 ): commercial organic mineral fertilizer (control), olive pomace compost A1 (OPC-A1) (composting mixture with C/N ratio of 45 stopped at the end of active phase of bio-oxidation), olive pomace compost A2 (OPC-A2) (composting mixture with C/N ratio of 45 processed until maturation), olive pomace compost B1 (OPC-B1) (composting mixture C/N ratio of 30 stopped at the end of active phase) olive pomace compost B2 (OPC-B2) (composting mixture with C/N ratio of 30 processed until maturation)]on growth, yield and quality of emmer wheat (Diacono et al, 2012). They observed that different fertilization treatments had no significant effect on growth and yield of emmer, however, they found that olive pomace compost showed an increase of 9.8% in grain yield compared to commercial mineral fertilizer treatment.…”

Climate change is the greatest environmental threat facing humanity worldwide. Areas of South-East Europe and Mediterranean basin are expected to be among the most vulnerable countries to climate change. As a result of climate change, new species and crops have been introduced and may be introduced in the coming years. In addition, FAO considers that Organic Agriculture is an effective mitigation strategy to climate change and can build robust soils that adapt better to weather extremes associated with climate change. This review provides an overview of the growth performance of new innovative crops, including chia, camelina, quinoa, teff and nigella and retrovative crops such as flax and emmer wheat, based on experimental investigations conducted under Mediterranean conditions and organic cropping system. Several studies, performed under organic system, have proved that innovative crops can also be grown for alternative uses. Quinoa and chia could be successfully used in animal feed. Moreover, quinoa could be exploited as a medicinal plant due to saponins extracted from seed coats. Nigella and camelina seeds contain oils which can have several uses in pharmaceutical and food industries. Flax seed oil is rich in omega-3 fatty acids and can be accepted in the diets designed for specific health benefits. According to the literature, it is observed that innovative crops cultivated under organic system present better quality and similar yields as with those cultivated under conventional system, and in some cases, even higher. Taking all these into account, organic agriculture could also be characterized as innovative and not only as traditional.

Green organic fertilizers can be a valuable option to reduce the use of chemical fertilizers, improve the physical and chemical properties of soil, and promote circular agriculture. The effects of two fertilization schemes, (i) a combination of mineral fertilizers with dairy farm slurry (TA) and (ii) an organic substrate (SO) from green waste (TB), on soil fertility and forage maize (Zea mays L.) yield were studied in an on-farm trial in the Azores Island of S. Miguel (Portugal). For this purpose, soil chemical parameters were evaluated on three sampling dates, forage maize yield and yield components were compared, and the balances of soil carbon (SC), nitrogen (N), phosphorus (P), and potassium (K) were evaluated. The results showed that the maize yield obtained in TB was significantly higher than in TA. The differences in precipitation that occurred over the two years influenced the yield in both treatments. The SC, available P, and pH were significantly higher in TB at every sampling date, mainly in the subsurface layer, and overall enrichment in nitrogen was observed. Despite the need to extend this evaluation over a longer period, the results indicate that the application of SO could be an alternative to conventional mineral fertilization in forage maize in the Azores and in similar cropping systems in regions of temperate insular nature.
