Wheat and its Cultivation. 



by wiu^at ri'ops is very siiiall iiidt-pd. It is not likely to he of vahic in 

 the wheat areas, except in the ease of certain sandy soils deficient in 

 this ingredient. With legnininous crops the most economical method 

 of supplying potash will prol)ably be the application of compounds, 

 such as lime and gypsum, which will lil)erate the insoluble potash com- 

 pounds and render tliem available. This matter, however, was dis- 

 ctissed in tlu' Sc])teniber issue of the Jounial. 



General ^Manures. 



These supply all the elements required l)y plants for their perfect 

 development. 



The most important manures of this section are Stable and Green 

 manures. 



Stable Manure is one of the most valuable manures that can be 

 applied to any soil to increase its fertility. In the older agricultural 

 countries of the world the greatest care is taken in the preservation of

all the nianurial resources of the farm. Under the conditions which 

 obtain in the wheat areas of Australia at the. present time, farmyard 

 manure is practically neglected, and regarded as of minor importance. 

 The average wheat holding at the present time is so large, and the 

 amount of stable manure produced in a year so small, that the effect 

 of the stable manure on the fertility of the farm will, for all practical 

 purposes, be inappreciable. This state of affairs will not. however, con- 

 tinue indefinitely. With the rapidly increasing population, and the 

 inevitable increase in land values ahead of us. individual holdings must 

 gradually become much smaller in size, and the system of farming more 

 diversified. Live stock will become more and more prominent, and 

 ultimately the amount of farmyard manure produced on the farm will 

 be sufficient to have a distinct effect on the fertility of the farm. On 

 the dairy farm, however, as contrasted with the wheat farm, farmyard 

 manure is of great importance. The majority of such farms are situ- 

 ated in the moister districts, where systematic rotation is possible.
