46 THE MANURING OF ARABLE LAND [OH. 



Spring. 1J to 3 cwts nitrate of soda or sulphate of ammonia 

 or, if bad tilth is feared, 30 bushels of soot. The large dressings 

 must be given in two applications, and not all at once. 



(2) 40 to 50 bushels normally produced. On this sort of land 

 no general advice can be given. On land of the brick earth type 

 that produces large heads well set with corn and borne on stiff 

 straw it may be safe to try and squeeze out a little more 

 produce by somewhat increasing the usual dressing, or by a 

 spring dressing of say about 1 cwt sulphate of ammonia or nitrate 

 of soda. On lighter land heavily sheeped, where the wheat 

 already tends to lodge badly, it would be too risky to attempt 

 this. With the prospect of short labour at harvest time one would 

 not like to contemplate the possibility of laid crops. 



If a second wheat crop is being taken, contrary to the terms 

 of the lease, but under the provisions of the Agricultural Holdings 

 Act of 1906, the following equivalent manurial ingredients per acre 

 must be returned to the soil : 



Phosphate 



Phosphoric Tricalcic 



Nitrogen Acid Phosphate Potash 

 Grain only sold: 



30 bushel crop 34 14 31 9 



40 ., 46 19 42 12 

 Grain and straw sold: 



30 bushel crop 50 21 46 29 



40 67 28 62 39 



The spring dressings suggested above would supply all the 

 phosphate and much of the nitrogen required, and sufficient 

 potash would probably be contained in the dung applied to the 

 following root crop. In case of dispute, however, it would be well 

 to consult the County Adviser. 



The seed should always be pickled before sowing to prevent 

 smut. Either of the following mixtures will suffice for 10 bushels 

 of seed: 1 pint of the ordinary 40 per cent, formaldehyde in 

 9 gallons of water, or 2J Ibs of sulphate of copper (bluestone) 

 powdered up and dissolved in 2^ gallons of water. Care must be 

 taken that the seed is treated uniformly, as any that gets too great 

 a dose may fail to germinate.
