It will be seen that in each case about six times as much potash was 

 extracted from these soils by Method I. as by Method V., and in two cases 

 the quantity of phosphoric oxide extracted by Method I. was about 3 to 3 

 times that obtained by Method V. In the third soil the directly available 

 phosphoric oxide was only one-ninth the available reserve. 



On the basis of the minimum limits suggested by Dr. Dyer, viz., '005 

 per cent, of potash and '010 per cent, of phosphoric oxide, the first two 

 soils, at all events, are sufficiently well supplied with these elements of 

 plant food in a state ready for immediate use.

Two fine-grained soils were collected from the farm Fluitjes Kraal: 

 No. 1 had the characters of a good Karroo soil, and was typical of a con- 

 siderable area. No. 2 was taken from what is known as vlei land. 



The analyses of these two samples resulted as below:

The proportion of phosphoric oxide in these soils is low, nor are they 

 particularly well supplied with nitrogen,; on the other hand, they are both; 

 rich in lime, in this respect resembling many of the soils of the neighbour- 

 ing Divisions of Albert, Aliwal North, and Colesberg.
