PROFITABLE FARMING. 31 



bag, transport and sell one ton of high-grade 

 fertiliser than it does a low-grade one containing 

 perhaps less than one-half the quantity of plant 

 food. Moreover, superior crop results are ob- 

 tained from the use of a complete fertiliser of 

 suitable composition for each particular crop, 

 &c. 



Manuring of General Farm Crops 



IT will already be clear that whilst a combina- 

 tion of phosphates, nitrogen, and potash is 

 necessary for the profitable growth of all crops, 

 it must be borne in mind that these are required 

 in varying proportions according to the domi- 

 nant or principal element demanded by each 

 particular crop. 



As certain important factors must be taken 

 into consideration, such as variations of soil, 

 climate, rainfall, &c., it is practically impossible 

 to lay down any hard and fast rules as to the best 

 fertiliser or combination of fertiliser to use in 

 each particular case. The most that can be 

 done is to show the results of independent ex- 

 periments and observations in different parts of 

 the country, modifications of which can be 

 adapted by practical men as most suitable to 

 their individual circumstances, always bearing in 

 mind that whatever the crop and wherever it is 

 grow r n, it will require the same elements of plant 

 food and in the same proportions.
