2I.I The table first contains the data on the soils provided by Françoise Panoff,29 secondly a brief description of the nature of the samples and thirdly the analytical data. The ratings of these data follow the normal standards used by us in our surveys in New Guinea. It may be useful to note that even the low N (nitrogen) figures are high by Australian standards, but for P (phosphorus) and K (potassium) as well as for pH the standards are more universally valid, and not particularly related to New Guinea conditions.

3I have grouped the soils essentially in order of increasing acidity, and this tends to correlate with site conditions, and with P and K contents. Within this framework, I have always kept pairs of cleared and fallow samples together. These pairs are usually clearly similar soils, except for the pH and K content of 7/8 and 9/10, which I cannot explain. For samples 31-36, 31-32 and 35/36 form a better pair than 33/34 and 35/36. For samples 19-24, the best pair is 21/22 and 23/24. This is indicated by the dotted lines.

4If one looks at the various pairs, the most striking thing is that N contents of fallow land are always lower than those of cleared land in the top-soil, but the reverse is usually true for the sub-soils. There is a similar but weaker tendency for K, but no systematic relation for P. There is a rather weak tendency for pH to be higher in fallow than in clearings.
