60 THE MANURING OF GRASS LAND [OH. 



lime is wanted: sorrel will tolerate lime quite well. But it can 

 do without lime better than many other plants, and when it 

 begins to spread at the expense of others it indicates that lime is 

 beginning to run short. 



So far as the plant is concerned it does not very much matter 

 in what form the lime is added : the farmer can therefore suit his 

 own convenience (see p. 3). 



One ton of ground lime or 2 to 4 tons of ground limestone are 

 useful dressings. Chalk is good where it can be got cheaply, 

 but if it is in big lumps it distributes so badly that large quantities 

 40 loads or more are needed. 



General recommendations for hay. To get bulk use 10 tons of 

 dung in autumn every third year, if it can be spared. When this 

 is not done use 1 to 2 cwts of nitrate of soda or sulphate of 

 ammonia in March. 



To improve the quality and give a little more bulk add to 

 this 3 to 5 cwts of basic slag or superphosphate; slag on heavy 

 soils, or wet places, or where the rainfall exceeds 26 inches a year ; 

 superphosphate under drier conditions, or where prices are higher 

 than usual so that you want to get as much as you can in the 

 first year. If the land scorches in summer, add to the other 

 artificials 3 cwts of salt or of kainit if it can be got. 



To sweeten the herbage, apply 10 cwts of lime, or 1 ton of 

 ground limestone, as early as possible. 



Pasture Land. 



The main factor determining the success of pasture land is the 

 management: the land requires proper grazing even more than 

 proper manuring, and unless it is well grazed money spent on 

 manures does not give its full return. 



Assuming the management to have been good, and the land 

 well grazed by stock receiving cake, there is no need to add any 

 manure except occasional lime and phosphates. If nothing has 

 been added for a number of years it will be well to try whether 

 better results could not be obtained from dressings of super- 

 phosphate or of basic slag: many cases are on record where 

 these have improved the feeding value of the herbage, even on 

 good pastures.
