The quantitative isolation of algae from soils. A suggestion for standardization

Data about number and amount of algae in soils are difficult to compare sin ce they are equally dependent on site factors (e.g. soil type, depth) and o n methods of isolation. In this study current methods of isolation are test ed and revised as to efficiency and validity. As a result the protocol of a new more efficient, isolation method is suggested as a standard method for further investigations.
