| The following paper shows the impact of organic farming on the development of contents of phosphorus, potassium and magnesium in the soil. The basis is a six-year crop rotation with animal manures (85 dt/ha/a) in the location of Gülzow (Mecklenburg- Prepomerania). From 1993 to 2004 samples of soil were taken with aan soil auger in a depth between 0 and 30 cm. The discussion of changes in chances of the nutrient contents nutriens content is connected with nutrient balances. As a result, nutrients bilances, witch are in balance. On this time the the contents of potassium shows decreasing tendency. Organic farming does notno lead to lower contents of phosphorus and magnesium. The impacts of soil and year are high. |

| This brief and practical information leaflet for blue, yellow and white lupins serves a farmer to get introduced to its cultivation. Aim is to promote the cultivation of lupins due to its beneficial effects as precrop, as it fixes nitrogen, makes phosphorus available and is high in proteins. This leaflet describes soil properties, water supply and weed pressure conditions for a successful cultivation of each lupin species. Furthermore recommendations in variety choice, crop rotation, mixed cropping are given i.e. soil tillage, vaccination, sowing, fertilization, mechanization and weed control by hoeing and harrowing, harvesting, processing (for animal feed and human food), economic assessment. As conclusion the most important pros and cons of lupin... |
