The following points highlight the five methods of sampling plant communities. The methods are: 1. Transect Method 2. Bisect 3. Trisect 4. Ring Counts 5. Quadrat Method. 1. Transect Method: When the vegetation is to be studied along an environmental gradient or eco-tone (e.g. tropical to temperate, high or low rainfall areas or precipitation gradient, adjacent areas with different types [...]
In this article we will discuss about the procedure for analysing the quality of air. High Volume Sampler is a basic instrument used to monitoring ambient air quality. The sampler provides, in general, devices for basic measurement of air-borne particles, gaseous pollutants like SO2, NOx and CO. In the sampler the air-borne particles are measured by passing air at a [...]
In this article we will analyse various properties of water which affect plant growth:- 1. Hardness 2. Chloride 3. Dissolved Oxygen (DO) 4. Iron. 1. Hardness (EDTA Titrimetric Method): Water hardness is the traditional measure of the capacity of water to react with soap, hard water requiring a considerable amount of soap to produce lather. Hardness of water is not [...]
