| The acquired information on biomass production and expected nutri-ent release of cover crop species and/or cultivars will provide greater certainty for the selection of suitable varieties and the estimation of fulfilment of the nutrient requirements of the subsequent crop. Method and results of practical testing MERCI is an easy-to-use tool which simplifies: • Estimation of the dry matter produced per hectare (tonnes per hectare); • Calculation of the nitrogen trapped (or stored) by the cover crop; • Definition of the nitrogen refund levels for the subsequent crop (kg/ha). The references used in the calculations are based on more than 10 years of trials on cover crops in Poitou-Charentes/France. Simulations are carried out with INRA's STICS... |

| On the one hand, through the analysis of remote sensing images, it was possible to determine weed infestation, field heterogeneity and NDVI values/pixel (app. 1 cm per pixel). In some cases, we even discovered previously unknown underground field objects (e.g. a drainage system from the 70s). On the other hand, NDVI data did not correlate with traditional sampling results (SPAD values and yield estimations), probably because the multicopter covered 100 % of the large plot area, while sampling only provided data from specific points (50 SPAD points/plot and three yield sampling quadrats/plot). We can thus assume that for large plot variety trials, remote sensing can give substantially more precise results than traditional sampling methods. Further tests... |

| Using NDICEA, farmers can identify where problems with nutrient loss/imbalance occur in their rotation. They can experiment with changes in rotation or management to find the most effective strategies to address nutrient imbalances and nutrient losses due to leaching. Practical recommendation • NDICEA is a freely available, computer-based nutrient budgeting tool developed by the Louis Bolk Institute in the Netherlands. It takes data on the crop rotation for an individual field rotation, alongside data on climate, soil properties and management practices (e.g. seed rates, fertiliser application, cultivation regimes etc.) to map changes in soil nutrients over the course of the rotation. • Application of the tool on seven organic farms found that, of... |

| NDICEA presents an integrated assessment of the question of nitrogen availability for organic crops. During the growing season, the model compares net available nitrogen from manures, crop residues, green manures, additional fertilisers and the soil, with the crop specific demand on a daily basis. The release of nitrogen from different types of organic matter in the soil is calculated, considering soil type, temperature, rainfall and losses due to leaching and denitrification. The NDICEA model has been developed, tested and used during more than 15 years by the Louis Bolk Instituut in the Netherlands. The interface is user-friendly, with complex calculations in the background. This offers an easy way to obtain a reliable indication of the nitrogen and... |

| The purpose of the tool is to help farmers in estimating the N content of forages based on the percentage of legumes, the management and harvesting method. It is based on an Excell file that uses two databases containing information on site specific forages. It is a Decision Support Tool (DSS) in 2 languages, easy and fast to use. It is complemented by other tools (on crop rotation, legume content estimation) available on the web page and by other information materials. To go to the tool please go to "Software Tools Ökolandbau" and then "Stickstoff-SaldoRechner". To Switch to the German version, go to the top of the page and click on "DE". |

| Optimal fertilisation ensures that the current rapeseed varieties and reach their full yield potential. Practical recommendation • In conventional cultivation, the nitrogen uptake of winter oilseed rape amounts to 140 kg N per ha for a yield expectation of 35 dt per ha. In organic agriculture, about 100 kg suffice for a yield expectation of 20-25 dt. • The ideal time for cultivating oilseed rape is after grass-clover or legumes. After grains, apply about 30 tonnes per ha of manure or manure compost before cultivating rapeseed. • In dry conditions in spring, an early single application of nitrogen is preferable to two smaller applications. In the case of slurry with a low N content, two applications are often required because maximum of 40 m3 of slurry... |

| The non-tilled, constantly covered soil has improved water retention and also shows a better carrying capacity during harvest, and is less affected by weed infestation, compaction, nutrient-leaching, and erosion. Stockless farms especially benefit from the nitrogen input of the legume-green manure. • At the beginning of August, carry out 1 to 2 stubble-tillage operations after cereal or rape harvest. • Sow the wintering forage peas in October. • At the end of May, kink the peas' stems with a knife-cylinder roller, after which you drill in the maize with row cleaners. The green manure lying on the ground must be properly dried off for sowing. • The mineralisation performance, lowered due to the soil cover, can be compensated for with focused nitrogen... |

| This webinar is focused on nutrient management on organic systems. It is addressed to US farmers, especially in the part dedicated to regulations. Agronomic information presented by the relator will be useful also for European organic farmers, both experts and newcomers. It is organised in sections: US regulations; evaluation of crops nutrient requirements; evaluation of nutrients release from organic matter, amendments and cover crops; fertilization, timing and application methods; leaching and runoff risk. Data values are presented in US units of measure: pounds per acre. The conversion factor to kg per ha is nearly 1 (1.12), so quite straightforward. |

| Stock pests can cause severe damage to agricultural products. In addition, it is sometimes difficult to determine the pest and know what measures would be most helpful.. The online tool helps determine the pest and provides information on its biology and suitable measures. It contains data on more than 40 storage pests, and it is being expanded continuously. First, the pests can be filtered by organism group, location of infestation and infected product. Thus, only matching pests are displayed in a list. For each pest, there is a description of its appearance and biology, its pattern of damage and suitable control strategies. The tool only suggests measures that are permitted in organic farming. Therefore, it can be quite helpful for organic farmers,... |

| Tilth, Oregon. |
| Oregon tilth webinars promote the transition to organic farming through practical illustrations of good agronomic practices and organic policies. Practices are explained through field trials conducted by the extension services and farmers direct experiences. They can be accessed any time and offer a certificate of participation. Webinars are targeted both to converted farmers and experienced organic farmers. Being agronomic themes (i.e. cover crops, soil regenerative practices, resources conservation), also conventional farmers can profit from them. These webinars are focused on arable land and on non-ruminant livestock of the North Western part of the USA. Some of them are specific for that area (grant policies, surveys), others are more generic and the... |
