 richest possible. 



On pasture slag should be applied in January 

 or February. We must point out here that very 

 fine basic slag of good quality ought not to be 

 applied earlier. In doing so there is a risk of loss, 

 since it is here used as a top-dressing. As a matter 

 of fact, we have seen that these very fine particles are 

 the best slag, also that they are most easily carried 

 away by the wind, or washed away by heavy rains, 

 so that the earlier they are applied the greater the 

 risk of loss. Moreover, this is just the time of year 

 when the grass is shortest, so that the manure will 

 be most easily carried away by heavy rains. 



For other crops the slag should be buried by 

 a good harrowing, so as to mix it thoroughly with the 

 soil, before sowing. In this case no loss need be 

 feared. It should never be given to ordinary crops 

 as a top dressing. On clovers it is better to give a 

 double dose at the time of sowing the crop preceding 

 the clover, so that it can be well distributed in the soil. 



It should never be sown in windy weather, because 

 the best and finest particles will fly furthest. They 

 would often fall from lOO to 150 yards from the 

 place for which they were intended, and be of no 

 use to the plants that ought to receive them. To 

 prevent slag from blowing away it can be mixed with 

 kainite the day before it is used. This mixture, 

 however, will become hard, and therefore ought to 

 be used at once. 



Slag should be spread by machine for preference. 

 If sown broadcast the sower should take care not 

 to work against the wind, because the lime in the
