The extraction of Al, Fe and Si from a range of New Zealand soils by hydroxylamine and ammonium oxalate solutions

Some 36 samples were analysed from 8 different soils and the results for each extractant were compared. Although statistically significant, differences between individual values were generally small. Results are compatible with previous studies which indicated that hydroxylamine provides an approxim...

Summary:Some 36 samples were analysed from 8 different soils and the results for each extractant were compared. Although statistically significant, differences between individual values were generally small. Results are compatible with previous studies which indicated that hydroxylamine provides an approximation of oxalate values for Al and Fe. Unlike previous work, however, the present results also suggest that approximate values can be obtained for Si.
