CONCLUSIONS 189 



of nitrate of soda when the grass begins -to grow, will be 

 remunerative. 



. 6. On light dry soils, either sandy or chalky, the nitrogenous 

 manures are the most important ; dung, and cake-feeding the 

 aftermath, will best build up a vigorous herbage, and until this 

 is done it will not be wise to spend much money on artificial 

 manures : 1 cwt. of nitrate of soda, 1 cwt. of superphosphate, 

 and 3 cwt. of kainit, being about the best proportion in which 

 to employ them. 



7. On all old grass land an occasional dressing of ground 

 lime, at the rate of half a ton per acre, applied in the early 

 winter (best in the year following the dunging), will sweeten 

 the herbage and utilise the reserves of past manuring.
