150 CONTINUOUS CROPPING 



that if a rye pasture is sown, the winter greens following 

 will be rape, kale, etc. 



If rape be sown first, it will not do to sow rape a 

 second time, as there may be a danger of finger-and-toe 

 disease. Therefore a good portion of rye with scarlet 

 clover or a little vetch may follow the rape. Kales may 

 also follow rape. These, belonging to the same order 

 as rape, are also subject to *■ finger-and-toe,*' but in 

 the writer's experience by varying the different types 

 of cruciferous crops — rape, kales, hardy greens — after 

 each other, he has never had a case of finger-and-toe. 

 This may be due to the fact that the spores which 

 cause the disease are in a resting stage in winter. 



The winter-green crop will not require very much 

 manure, about 2 cwt. of a suitable phosphate and 

 I cwt. of a nitrogenous manure per statute acre being 

 generally ample. 



The winter greens also will be eaten where grown, 

 and in this way a magnificent crop of tares can then 

 be obtained, without any further manuring. Again, 

 after the tares, seeds hay will not require manuring, 

 whilst the seeds for soiling and folding in the fifth year 

 will do quite well with whatever farmyard manure has 

 accumulated. In fact this will be the most convenient 

 time to apply the farmyard manure to the crop. 



Roughly, the cost of the manure and lime in the 

 first year's break will be about £z 15s. and in the 

 second year £1 per statute acre, giving a total expendi- 

 ture on manures of about £3 15s. per acre during the 

 five years of the rotation, or an annual expenditure 

 of about I2S. 6d. per annum per acre, which must be 

 considered low in comparison with the amount of food 

 produced.
