The foregoing results are iudicative of great crop producing power The soil con- 

 tains an abundance of organic matter rich in nitrogen and the mineral elements of 

 plant food — and especially potash — are for the most part present in amounts equal 

 to those in many of our finest and most fertile soils. It may further be stated that the 

 percentages of potash and phosphoric acid in an ' available ' condition are considerably 

 above the average. 



"What perhaps might be termed a weakness of this soil is its small lime content. 

 This fact, in conjunction with the slight, but distinct acid reaction of the soil, leads 

 me to suggest an application of lime, wood-ashes or basic slag as most probably th^ 

 tieatment which above all would give increased crop yields. It is essential, however, 

 that the drainage be made as effective as possible. 



Lime might be applied at the rate of 25 to 40 bushels per acre; wood-ashes, 35 to 

 50 bushels, and basic slag, 300 to 500 pounds per acre. The latter fertilizer, owing to 

 its alkalinity, would, I think, on this soil be a more suitable form, in which to furnish 

 lime and phosphoric acid than superphosphate, which is an acid form of phosphoric 

 acid. From the standpoint of economy, it might be advisable to give lime a trial be- 

 fore investing in the more expensive basic slag. 



Special examination was made for salt, as it was stated that the tide occasionally 

 overflowed the land, but the amount found, 0'023 per cent, was so small that its presence 

 could not be considered as at all injurious to crops. 



Kvalf, on Sliuswap LaJce, near Salmon Arm. — 'Virgin' soil from the south side 

 of mountain (Notch Hill) with a lake on the east side of it. It is somewhat elevated, 

 but can be irrigated if necessary. 



This is a light-grey sandy loam, and having the appearance of being deficient in 

 humus.

The data makes it evident that the want here is organic matter (humus) and its 

 concomitant nitrogen, and we liave again to advise the growth and ploughing un- 

 der of green crops (preferably clover or some other legume) to supplement the avail- 

 able supply of farm manures. 



Probably the application of immediately available nitrogen (as in nitrate of soda) 

 will be necessary to induce a vigorous growth until the soil, by the means just advo- 

 cated, becomes richer in this element.
