| It offers videos, dossier and short info-sheets reporting practical farmers experiences. At today, for arable crops, it includes a dossiers on direct-drilling in crop residues or living mulches, a dossier on crop association (companion planting) with several details on how to do it in practices and what still needs to be fixed in order to be successful in certain situations, and a dossier on biological control as a tool to manage habitats. The language of the platform is very direct and it is easy and fast to use. The platform is a dynamic tool so further material will probably be added in the future. |

| 1. In order to evaluate effects of straw mulch applied at 2.5 – 5 t ha-1 in organically grown potatoes (Solanum tuberosum L.), 21 field experiments were conducted over five years at two locations Northern Hessen and Southern Niedersachsen, Germany). The experimental sites were characterised by temperate climate conditions (635 – 709 mm precipitation year-1; 8.1°C mean air temperature) and loamy silt soils. The main focus of the study was on aphids and the aphidtransmitted Potato virus Y (PVY). This disease is a main problem in seed potato production. In addition to virus and vectors, associated agronomic effects of straw mulch were studied. 2. Straw mulch significantly reduced the incidence of PVY. It was most effective as a protectant for young plants... |

| A new arbuscular mycorrhizal, Paraglomus-like, fungal species (Glomeromycotina) was found and propagated in single-species cultures established from spores coming from Oman, Greece, Tunisia, and New Caledonia. The hyaline spores of the fungus are small, 17–67 μm diam. when globose. Their spore wall consists of an evanescent, 1.0–2.3 μm thick, short-lived outer layer and a laminate, smooth, 3.8–7.3 μm thick inner layer, of which none shows amyloid or dextrinoid reaction in Melzer's reagent. Mycorrhizal structures (arbuscules and hyphae without vesicles) of the fungus stained slightly in Trypan blue, thus like those of the formerly described Paraglomus spp., in which the histochemical feature has been recognized. However, in the phylogenies gained from... |

| Field studies have revealed the impact of changing water regimes on the structure of arbuscular mycorrhizal fungal (AMF) communities, but it is not known what happens to the abundance of individual AMF species within the community when the water conditions in the rhizosphere change. The behavior of four AMF species isolated from the Arabian desert (Diversispora aurantia, Diversispora omaniana, Septoglomus africanum, and an undescribed Paraglomus species) was investigated when assembled in microcosms containing Sorghum bicolor as host plant, and treated with various water regimes. Furthermore, the impact of invasion of these assemblages by Rhizophagus irregularis, an AMF species widely used in commercial inocula, was studied. The abundance of each AMF... |

| Phylogenetic analyses of sequences of the SSU–ITS–LSU nrDNA segment and the RPB1 gene showed that the arbuscular mycorrhizal fungus originally described as Diversispora omaniana does not belong to the genus Diversispora, but represents a separate clade at the rank of genus in the family Diversisporaceae of the order Diversisporales. The closest natural relatives of the fungus proved to be species of the genera Corymbiglomus and Redeckera. Consequently, the new genus was named Desertispora, and Di. omaniana was renamed De. omaniana comb. nov. In addition, the morphological and histochemical features of spores and mycorrhizal structures of a new Diversispora sp., Di. sabulosa, were described and the closest relatives of the species were determined based on... |

| Demand for organic foods, especially vegetables has increased tremendously due to reasons such as safety, environmental concerns, flavour and freshness, health benefits and nutritional value. In the current agricultural production environment, conventional farming methods pose the greatest risks in terms of reduced crop yields due to soil degradation. In the face of climate change and variability (CCV), field experiments are limited and without appropriate modelling techniques future crop production scenarios can’t be predicted leading to food insecurity. A survey and field experiment were done to assess crop productivity under organic based cropping systems and impact of CCV on soil nutrients and maize yields during the short and long rains seasons of... |

| Naranjilla (Solanum quitoense) is a perennial shrub plant mainly cultivated in Ecuador, Colombia, and Central America where it represents an important cash crop. Current cultivation practices not only cause deforestation and large-scale soil degradation but also make plants highly susceptible to pests and diseases. The use of arbuscular mycorrhizal fungi (AMF) can offer a possibility to overcome these problems. AMF can act beneficially in various ways, for example by improving plant nutrition and growth, water relations, soil structure and stability and protection against biotic and abiotic stresses. In this study, the impact of AMF inoculation on growth and nutrition parameters of naranjilla has been assessed. For inoculation three European reference AMF... |
