Assessments Soil Analysis:
These are only rough guides, for many plants have complex metabolic systems in which there may be interactions between an excess of one nutrient and perhaps a deficiency of another. Physical conditions also play an important part in the growth of a plant and for correct assessments soil analysis is vital.Fertilizer will be necessary. Theoretically it is possible to determine from a soil analysis exactly which nutrients are lacking and in precisely what amounts each should be given. Practically, it doesn't work that way. In the first place, a soil test, which is simple and inexpensive to make, is not a complete analysis. A complete analysis is costly. And secondly, even a complete analysis does not completely reveal the availability of the nutrients in the soil. Common sense and judgment based on experience and empirical knowledge must still play a large part in determining which fertilizers to use and in what quantities. Nitrogen, phosphorus and potash are the elements most essential to add, and it is important that at least one half of the nitrogen be in "organic" form so that it is released comparatively slowly. Some of it may, often with advantage, be in more quickly available form, although excellent results are had from organics alone.
Before finalising planning the teacher may need to make further informal assessments of an individual child in order to confirm a specific area of achievement. This may be necessary if the parents' view of the child's ability in a specific area differ from the findings of the Baseline Assessment. Alternatively the teacher may feel that the child's ability in a specific area is not reflected by the baseline score. This decision would normally be based on the teacher's prior informal assessments, and their general 'feel' for the child. Once any additional assessments have been made the teacher plans an appropriate programme of study.
