Malachite green method has been evaluated for estimating minute quantities of phosphorus (P) in water, 0.01M calcium chloride (CaCl2), and Olsen [sodium bicarbonate (NaHCO3)] extracts often soils of varying properties. The precision and accuracy of the malachite green method was better than that of the ascorbic acid method to estimate P in these three extracts. The recovery of added P ranged from 95.3-99.3% in water, 96-100% in 0.01M CaCl2, and 96.7-100% in Olsen extracts. The ascorbic acid method underestimated the amounts of 0.01M CaCl2-P and its precision was also lower than the malachite green method. It is possible to predict the P concentration in the three extracts equal to malachite green method from the ascorbic acid P values by using regression equations. Not Available |
