The sewage sludge was extracted from the wastewater treatment plant of Beni-Mellal city (Morocco). The extracted sewage sludge was composted alone, mixed with domestic solid waste, with olive cakes and with sawdust. The experiment was carried out in pots of vegetation under natural conditions. The humidity was maintained close to 80% of the field capacity. Ray-grass from Italy was used as a plant test. The research lasted 140 days, during which 4 cuts of the plant were investigated. The results obtained showed that all the amendments tested allowed an increase in the output in dry biomass and nitrogen plant uptake. This increase was more significant with non-composted and composted sewage sludge alone than with the other co-composts. The apparent coefficient of nitrogen utilization (CAU) recorded oscillated between 50 and 38%, testifying a great aptitude of the amendments tested to provide nitrogen to plants. The values of the apparent rates of nitrogen mineralization obtained were 38, 29, 28, 27 and 25%, respectively, for non-composted sludge; sewage sludge compost; sewage sludge-olive cakes compost; sewage sludge-domestic solid waste compost and sewage sludge-wood sawdust compost.","PeriodicalId":7644,"journal":{"name":"Agronomie","volume":"31 1","pages":"487-492"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73815045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extensification is the process of reducing fertiliser inputs, management intensity and stocking rates, and is central to these sustainable rural policies. However, research in the Less Favoured Areas of Europe has been fragmented and highly variable reflecting the different uses and requirements of our upland areas. Information is needed to determine the nature and timescale of changes in such systems, and whether extensive management is sustainable in the long-term. This paper presents results from a range of grassland extensification experiments across Europe, mainly within the European Union, over the past 30 years that quantify the impacts on soil, plant and animal components of the system. All have the common theme of changing the focus of land management from solely the agricultural product to include a broader range of ecological and environmental objectives. Beneficial changes in biodiversity resulted from more extensive management treatments, but at the cost of reductions in total animal output, and in some cases a reduction in individual animal performance. However, it is clear that it is a long-term process to achieve many of these changes in biodiversity, and this must be recognised by policy makers. We recommend that future extensification studies adopt an approach that will allow their results to be applied throughout Europe.","PeriodicalId":7644,"journal":{"name":"Agronomie","volume":"7 1","pages":"447-462"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82185620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pretilachlor is a selective pre-emergence herbicide which is effective against annual grasses, sedges and broad-leaved weeds. The herbicide was applied in pre-seeding on a flooded rice field where water circulation was stopped for about 3 weeks after treatment. Pretilachlor concentration in the paddy water decreased by more than 90% during the first three weeks after the treatment. The amount of the herbicide in the paddy water gradually fell to levels below the sensitivity of the analytical method when water circulation was re-established. The pretilachlor concentration in the sediment gradually increased after the treatment, reaching the highest value 5 to 6 days later. The average DT 50 in water and sediment were 6.77 and 28.76 days in 2001, 4.68 and 15.01 days in 2002, respectively. The low percolation rate (0.95 and 0.79 mm day -1 in 2001 and 2002, respectively) and the high ratio of the herbicide adsorption on the sediment suggest that pretilachlor disappearance from the water was mainly the result of degradation.","PeriodicalId":7644,"journal":{"name":"Agronomie","volume":"31 1","pages":"473-479"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84720916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
