,Nutrient Supply in Organic Agriculture – Plant Availability, Sources and Recycling,trition through the actions of soil microbes. The organic principle of only fertilising the soil and not directly feeding the crop with water-soluble nutrients has no support in science. The release of organically bound nutrients in soil through biological activity is not necessarily synchronised wi

,Synthesis of the Apelsvoll Cropping System Experiment in Norway – Nutrient Balances, Use Efficiencis of N, P and K in six different cropping systems, each covering 0.18 ha of separately tile-drained plots, were either measured or estimated. The effects of the cropping system on the soil nutrient pools (total-N, -P, and-K) were evaluated using mass balances, and the usefulness of such balances to

How Will Conversion to Organic Cereal Production Affect Carbon Stocks in Swedish Agricultural Soilsiculture. Other crops were not considered due to difficulties in large-scale cropping of oilseed rape and potatoes organically because of pest problems. Four scenarios were used: 0, 8 (current), 20 and 100% organic cereal production. Conversion to organic cereal crop production was found to reduce t

Organic Food Production and Its Influence on Naturally Occurring Toxins,n. Research findings suggest that organic foods may possess higher levels of natural plant toxins than conventional foods based upon mechanistic similarities between natural plant toxin production and the production of plant secondary metabolites of nutritional interest. Specific field research conf

Lars Bergström,Holger Kirchmann,Gudni Thorvaldssonand descending orbits were merged into the database, and the landslide activity and intensity were assessed. The landslide state assessment was performed by means of a PSI-based matrix approach. The activity state of 205 landslides has been evaluated. As a result, the majority of the landslides have
