Difference between ulcer and d method for phosphorus estimation and soil
Answers
A Kjeldahl digestion method normally used for total nitrogen (N) was compared with NaOH fusion and dry ashing methods for determination of total phosphorus (P). Overall there was good correlation between the methods (r2=0.996). Results from the digestion method were on average 3.7% lower than the fusion and dry ashing methods, but there were significant differences between methods as shown by the regression analysis. The digestion method proved suitable for analysis of highly organic soils and some soils from the Pacific Islands. It was also useful for estimation of total ? in well‐weathered soils such as Oxisols and in A horizons, but not suitable for less weathered mineral soils.
Gastric and duodenal ulcers are two kinds of peptic ulcers. A peptic ulcer is a sore that’s on the inside of the stomach lining — a gastric ulcer — or the upper part of the small intestine — a duodenal ulcer.
