| This webinar is about Cover crops. They are an integral part of all organic cropping systems since they provide the foundation for organic nutrient management, pest control, weed suppression, and improving soil health. Andy Bary, Washington State University – Puyallup, explains the different classes of cover crops and the benefits each class provides. He also introduces the concept of “inter-seeding relay planting” or the growing of one crop planted between the rows of an existing crop, e.g. hairy vetch planted into corn. He discusses seeding techniques, species selection, and management strategies to ensure success. Weed suppression using summer cover crops is also discussed. The webinar is targeted both to newcomers and experienced organic farmers. |

| Physical fractionation is used increasingly to study the turnover of organic matter in soil. This essay links the methods of fractionation to concepts of turnover by defining levels of structural and functional complexity that refer to experimentally verifiable pools of organic matter in the soil. Physical fractionation according to size and density of soil particles emphasizes the importance of interactions between organic and inorganic soil components in the turnover of organic matter. It allows the separation of free and occluded uncomplexed organic matter and of primary and secondary organomineral complexes. This methodological approach recognizes that the overall regulation of decomposer activity is through the structure of soil, which determines... |

| Dit rapport bevat de resultaten van het vierde jaar van het project "Bedrijfsinterne Optimalisatie", en wel van het deelproject "Van Strien". Op diverse percelen zijn metingen uitgevoerd aan de bodem om de stikstof werking van maaimeststoffen in beeld te krijgen. Op perceel 1A (aardappelen in 2014) heeft de strook met maaimeststoffen 2,3 maal zo veel stikstof gekregen als de bedoeling was, als gevolg van een twee maal zo hoog drogestofgehalte als vooraf was ingeschat. Dit was echter niet terug te vinden in de gemeenten hoeveelheden N-mineraal in de bodem en in de gehele strook met maaimeststoffen was de opbrengst lager dan bij de standaard bemesting. Door een vroege Phytophthora aantasting moest er vroeg gebrand worde. Daardoor waren de opbrengsten zeer... |

| The aim of the present study was to examine decomposition of plant material (maize straw, green and rooibos tea) in stratified soils of the long-term tillage experiment, established in 1999 and shifted from conventional to organic farming system in 2015. The plowing in conventional tillage (CT) has been done by moldboard plow 20 cm deep, while in minimum tillage (MT), soil disturbance has been up to 10 cm deep by a Special disc harrow. More than 15 years of long term Minimum tillage, with reduced soil disturbances and improved residue management, resulted in stratification of soil organic carbon and nutrients with highest concentrations in the very topsoil. |

| P. fluorescens is used in agriculture and horticulture as a plant growth promoting rhizobacterium. It colonizes root surfaces effectively and excretes compounds that are influencing plant nutrient uptake and plant health. Soils with different initial biological fertility were analysed 18 and 60 days after inoculating the freshly sown wheat plants with a suspension of a rifampicine tolerant strain of P. fluorescens CHA0, in order to evaluate its survival and lasting effect on soil microbial biomass. P. fluorescens had a lasting effect in soils with low initial biomass, but no lasting effects were found in biologically active soils. |

| Soil from the Højbakkegård experimental (BioConcens) field was amended with nothing (control), each of two anaerobic digested (AD) materials (mixture of AD cattle manure and maize, mixture of AD cattle manure and cut off grass-clover material), raw cattle manure, and grass-clover in five individual treat-ments. The materials were incorporated homogeneously into the soil and sampled destructively at 0, 1, 3 and 9 days after incorporation. Besides, experiments were performed to follow the turnover of these materials, measured as accumulated respiration over a longer period. Measures included available organic soil carbon (cold- and hot-water extractable), soil mineral nitrogen concentration, soil pH, accumulated respiration over a two-week period, emission... |

| Reduced tillage is increasingly promoted to improve sustainability and productivity of agricultural systems. Nonetheless, adoption of reduced tillage by organic farmers has been slow due to concerns about nutrient supply, soil structure, and weeds that may limit yields. Here, we compiled the results from both published and unpublished research comparing deep or shallow inversion tillage, with various categories of reduced tillage under organic management. Shallow refers to less than 25 cm. We found that (1) division of reduced tillage practices into different classes with varying degrees of intensity allowed us to assess the trade-offs between reductions in tillage intensity, crop yields, weed incidence, and soil C stocks. (2) Reducing tillage intensity in... |
