According to Table II it will be seen that from six to eighteen 

 millions of germinating seeds are necessary to sow one statute 

 acre the number varying with the relative size and vigour of 

 the plants, and with their surface covering capacity. The figures 

 given are based on the results of careful observation made on 

 plots which have been sown down on various kinds of soil, both

While these figures may be taken as sufficient for leys and 



temporary pastures, it is advisable to increase these quantities by 



from 30 to 50 per cent, when sowing down permanent grass. In
