“…ASC may have impact on soil fertility (Thorup Montemurro et al, 2013), occurrence of weeds (Bàrberi, 2002;Hayden et al, 2012), diseases and pests (Masiunas, 1998;Patkowska et al, 2013). They increase soil carbon (C) sink potential (Mazzoncini et al, 2011), influence greenhouse gasemission (Sanz-Cobena et al, 2014) and improve system energy use efficiency (Gomiero et al, 2008;Canali et al, 2013). ASC can also greatly reduce leaching of nutrients like soil nitrate (NO 3 -) (Kristensen & Thorup-Kristensen, 2004).…”

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.

“…It is based on three fundamental principles: 1. diversification of crop rotation, 2. reduction of soil tillage and 3. permanent soil cover (FAO, 2017). Compared to classical plough tillage, reduced tillage has several advantages, such as reduction of fuel costs, decreased disturbance for soil organisms, preservation of soil fertility, higher soil macroporosity, better water retention (Holland, 2004;Lienhard et al, 2013;Mazzoncini et al, 2011;Murugan et al, 2014;Palm et al, 2014;Sapkota et al, 2012;Soane et al, 2012). In contrast, detrimental effects, such as increased soil density, reduction of mineralisation or slowing of soil warming, could be observed in reduced tillage systems, especially with direct seeding (Soane et al, 2012).…”

A B S T R A C TReduction of soil tillage is of paramount importance for agricultural soil preservation. However, it is often accompanied by yield reduction and weed management problems. In this perspective, cover crops could play an important role to alleviate weed infestation and sustain yield. In this study, the results from a three-year experiment of cover crop cultivation in different soil tillage treatments is presented, together with results from DayCent simulations on the long term evolution of soil organic carbon and total nitrogen. Eight cover crop treatments were set up as subtreatments in a long term experiment in Switzerland. Cover crops were cultivated for a short two-month period between two winter wheats. Substantial differences in cover crop growth were observed depending on cover crop species. In all tillage treatments, high cover crop biomass production allowed to supress weed biomass compared to the no cover crop control. Wheat grain yield was higher in the minimum tillage than in the plough treatment. In the no till treatment, wheat yield was notably low, except in the field pea treatments, where wheat yield reached values similar to that observed in the plough and minimum tillage treatments. In addition, these differences in biomass production translated into important differences in nutrient inputs, and even in soil nutrient concentration in some cases. Long term simulations showed that cover crop cultivation could increase drastically soil organic carbon and total nitrogen, especially in reduced tillage treatments. Altogether, these results demonstrated that the presence of a well-developed cover crop, even for only two months, allows to sustain wheat yield in a no till treatment. It impacts also soil fertility and nutrient cycling. This study shows that an accurate use and management of cover crops, in interaction with tillage reduction, could maintain yield and improve soil fertility in the long term.

“…This may be due to the short -term nature of the experiment (2 years). Other studies have previously highlighted the improvement in soil organic carbon content under no tillage practice after several years (Ouattara, 1994;Mazzoncini et al 2011;Dimassi et al 2014;Villarino et al 2014). According to Jenkinson (1990), most of SOM in agricultural soils is degradation resistant and turns over much more slowly.…”

Soil degradation is recognized as a serious constraint to crop production in sub-Saharan Africa. A study was conducted in Nadion, located in the South Sudan zone of Burkina Faso to assess the impact of no-till, tied ridging; ripping and conventional tillage combined with soil fertility management options on Lixisol structural stability after two years of treatments imposition. The fertility management options were control, 2.5 Mg ha -1 of compost every year, 100 kg ha -1 of NPK + 50 kg ha -1 of Urea, mulching (100 % crop residues applied) and 2.5 Mg ha -1 of compost + 100 kg ha -1 of NPK + 50 kg ha -1 of Urea. The results showed that soil structural stability index (StI) tended to decrease under ripping, tied ridging and conventional tillage practices after two years. The application of organic amendments by improving soil organic carbon storage, tend to improve soil structural stability.
