The main problem in the use of single extraction methods lies in the lack of uniformity in the different procedures used. In consequence, the results obtained are operationally designed depending on the experimental conditions used (type and concentration of extracting agent, soil mass to volume ratio, shaking time and speed of shaking). Soils are highly variable and complex and developing single extraction method specific to the soil of interest makes the job expensive and time consuming. Therefore developing a universal extractant that does an acceptable job of accuracy in identifying plant available nutrient is required.…mehr
