MANURING FOR PROFIT. 



Results of Experiments in Potato Cultivation. 



(/, T. Ramsaji. I'otato Expert.) 



Manures judiciously used — to the faraier — are analogous to quick 

 maturing loans bearing a higli rate of interest. That fact is becoming 

 more generally accepted as time goes on, and the business method of 

 advancing capital to the soil in the form of manures for crop is becom- 

 ing, not only more widely practised, but more liberal in its application. 



The results of this season, both on the farms of potato growers and 

 in the experimental fields conducted by the Department of Agriculture, 

 again give substantial proof of the benefits of the judicious application 

 of manures, alike to the crop and the grower. 



At Lake Tyers, on the property of Messrs. C. Hendrie and Sons, an 

 area was planted with potatoes of the Arran Chief variety in February. 

 Variation in manurial treatment was made over five sections, for 

 purposes of comparison. The scope of the experiment was limited by 

 the fact that no potash was available for inclusion in the trials. The 

 nature of the soil was sandy loam, not naturally rich, but of nice 

 physical character. A favorable season was experienced, and the crop 

 developed well, the necessary cultivation being given by Messrs. Hendrie 

 as circumstances demanded. The method of applying manures was to 

 broadcast these on the surface of the ground immediately before the 

 ground was ploughed and planted. 



Harvesting took plac^ on 28th May, and the table given on page 

 shows the results obtained. 



Results lik* these require but little comment. Two striking facts 

 are prominent : — 



1. Substantial profit accrued from investment on manures. 



2. Since less acreage need be worked to produce a given quantity of 



produce, liberal manuring economizes time and labour.
