Using model-evidence link diagrams to weigh alternative models in argumentation
50 S cientifically literate citizens need to understand how scientists evaluate competing explanations. Likewise, students must learn to critically evaluate the quality of scientific knowledge and weigh alternative explanations. Regrettably, high school graduates often aren’t critically evaluative about scientific topics. To help remedy that, this article presents an instruction scaffold—called...
متن کاملThe Fate of Phosphate Fertilisers in Soil
Phosphorus is thus naturally available in the soil. However, there isn't usually enough available for plants to grow well. Phosphorus levels are reduced by animals eating the plants then dying elsewhere so that the phosphorus is removed, and also by phosphorus being adsorbed into soil particles or washed away by excess rain. For this reason phosphate fertilisers are widely used. The ways in whi...
متن کاملManure and sorbent fertilisers increase on-going nutrient availability relative to conventional fertilisers.
The key to better nutrient efficiency is to simultaneously improve uptake and decrease losses. This study sought to achieve this balance using sorbent additions and manure nutrients (spent poultry litter; SL) compared with results obtained using conventional sources (Conv; urea nitrogen, N; and phosphate-phosphorus; P). Two experiments were conducted. Firstly, a phosphorus pot trial involving t...
متن کاملEctomycorrhizal fungi as an alternative to the use of chemical fertilisers in nursery production of Pinus pinaster.
Addition of fertilisers is a common practice in nursery production of conifer seedlings. The aim of this study was to evaluate whether ectomycorrhizal (ECM) fungi can be an alternative to the use of chemical fertilisers in the nursery production of Pinus pinaster. A greenhouse nursery experiment was conducted by inoculating seedlings obtained from seeds of P. pinaster plus trees with a range of...
