“…In the Southern European areas, farmers grow ASC in the rainy season, to exploit rain water, which is not a limiting factor in this season. Nonetheless, those farmers would also be interested in the possibility to design suitable cropping systems that include warm season break ASC, in order to optimise the rotations and to achieve the best economic and environmental performances (Butler et al, 2012). However, ASC and especially grass species can take up all the available water in the soil, so there could be a shortage of water for the following cash-crop, particularly during the summer, unless irrigation is used.…”

In sustainable/organic farming systems, Agro-ecological Service Crops (ASC) may provide many beneficial ecosystem services, when they are introduced as buffer zones, living mulches or break crops. This outlook paper focuses on: i) the role of ASC genotype and mixtures as catch crops for soil mineral nitrogen (NO 3 -) surplus, which is returned to the system after their termination; ii) living mulches and break crops management strategies, particularly comparing ploughing under (green manure) with termination by roller crimper; iii) summary of three recent case studies that have assessed the effectiveness of ASC management by no-till with roller crimper for tomato, zucchini and melon crops, under Mediterranean conditions. Recently, in central Italy yield and quality results on organic tomato indicated that this crop was suitable following termination of leguminous ASC by roller crimping. Similarly, this ASC management increased yield by about 70% compared to green manure in zucchini crop. In southern Italy, no substantial differences were found in the ASC management and organic fertilizer interactions in organic melon, confirming the suitability of matching these strategies to sustain crop production. More studies should be encouraged to further empower the use of ASC in a wide range of agro-climatic conditions. Furthermore, additional studies on the roller crimper should be performed, mainly to understand the dynamic of N mineralisation in the soil-mulch interface and synchronisation of N release with cash crop N requirements. Finally, Decision Supporting Systems (DSS) for ASC introduction into vegetable cropping systems should be developed.

“…BSD based on supplying labile carbon to stimulate microbially driven anaerobic soil conditions in moist soils covered with polyethylene mulch (Butler et al 2011) has been proved to be effective against a wide range of soil-borne pathogens, such as F. oxysporum f. spp. lycopersici, spinaciae and radicis-lycopersici, F. redo len s, Phomopsis sclerotioides, Pyrenochaeta lycopersici, Ralstonia solanacearum, and Verticillium dahliae, as well as the nematodes Meloidogyne incognita and Pratylenchus sp.…”

Banana Fusarium wilt caused by Fusarium oxysporum f. sp. cubense (FOC) is a worldwide soilborne disease that causes serious economic losses every year. Effective ways of preventing the disease are still not available. In this study, biological soil disinfestation (BSD) with incorporation of various organic matters under flooding conditions combined with plastic mulching was applied to suppress FOC and prevent banana Fusarium wilt disease. The biological properties of the soil during the BSD process were investigated using quantitative real-time PCR and denaturing gradient gel electrophoresis. The results showed that the values of soil redox potential significantly decreased by >800 mV in the treatments that incorporated rice straw and bagasse under flooding conditions compared with untreated soil. The lowest soil pH (5.36) and a significant decline in the FOC population to 2.79 % of untreated soil were obtained in flooded soil with the highest amount of rice straw. Incorporation of bagasse, pig manure, and lime also significantly decreased the populations of FOC, but were less effective than rice straw. Application of rice straw under flooding conditions significantly increased soil bacterial diversity, and the increased bacteria were considered to have an antagonistic effect on FOC. In 2013 field experiment, a wilt disease control efficiency of 82.3 % was obtained in flooded soil incorporated with 0.5 % (w/w) rice straw compared with untreated soil, and the control efficiency of BSD was further confirmed in 2014 field experiment. These results indicated that BSD can reduce FOC populations in soil, ameliorate soil microbial communities, and reduce the occurrence of banana Fusarium wilt disease.

“…It have been widely used as alternatives to chemical pesticides for reducing the number of soil-borne pathogens and nematodes in the soils (Goud et al 2004). BSD involving incorporation of labile organic carbon to stimulate anaerobic metabolic activities in moist soils covered with plastic membrane (Butler et al 2012a) had been proved to be effective against a wide range of soil-borne pathogens, such as F. oxysporum f. spp. lycopersici, spinaciae and radicis-lycopersici, Fusarium redolens, Phomopsis sclerotioides, Pyrenochaeta lycopersici, Ralstonia solanacearum, and Verticillium dahliae, as well as the nematodes such as Meloidogyne incognita and Pratylenchus sp.…”

Toxic organic acids produced in biological soil disinfestation mainly caused the suppression of Fusarium oxysporum f. sp. cubense

Biological soil disinfestation (BSD) is an effective and environmentally friendly way to suppress soil-borne pathogens. Although it is increasingly used in USA, the Netherlands and Japan, its precise mechanism has not been well quantified so far. Quantitative real-time PCR, denaturing gradient gel electrophoresis and high performance liquid chromatography were used for investigating the role of organic acids in the mechanisms of BSD. The results showed that BSD significantly reduced the population of Fusarium oxysporum in soil. Simultaneously, in BSD treatments, the soil pH significantly decreased and some organic acid producers, such as Clostridia sp., were observed. Four kinds of toxic organic acids to F. oxysporum were detected in soil solutions of BSD treatments. Acetic acid and butyric acid were the primary organic acids, followed by small amounts of isovaleric acid and propionic acid. The verification test directly demonstrated that the toxic organic acids with the maximal doses detected in BSD significantly suppressed F. oxysporum, Rhizoctonia solani and Ralstonia solanacearum.
