GRASSES IN ILLINOIS 367 



farm implements. With more live stock will come the demand for 

 pastures and meadows. 



ILLINOIS. Prof. O. D. Center of the Illinois College of Agricul- 

 ture, Urbana, 111. : While the list of available grasses is long, 

 there are a few that are always serviceable, and are of greatest 

 value. These in the order of their importance for pasture grasses 

 in Illinois are: Kentucky bluegrass (Poa pratense), redtop (Agros- 

 tis vulgaris), timothy (Phleum pratense}, orchard grass (Dactylis 

 glomerata), perennial ryegrass (Lolium perenne} and meadow fox- 

 tail (Alopecurus pratensis). This list includes only the true 

 grasses that are of unquestioned value. It is also common to in- 

 clude in this list the clovers, medium red, alsike, and white, as 

 well as alfalfa, which last mentioned certainly comes more truly 

 under the head of meadow plants than those for pasture. We 

 have such a diversity of soil types in Illinois that no one mixture 

 will do for all locations. Classifying the soils as good land well 

 drained, land of ordinary fertility poorly drained and poor soils, 

 dry, gravelly and broken, we present the following mixtures for 

 permanent pasture: 



Good land well drained, 



4 pounds Kentucky bluegrass =Poa pratense 



2 pounds Redtop == Agrostis vulgaris 



2 pounds Orchard grass = Dactylis glomerata 



3 pounds Timothy = Phleum pratense 



1 pound Meadow foxtail =Alopercurus pratensis 



1 pound Perennial ryegrass =Lolium perenne. 



2 pounds Alsike or white clover 



or a mixture of both. 



This variety of grasses and the amounts of each give a total 

 of 15 pounds of seed per acre which will, taking the number of 

 seeds per pound of the different sorts and the average per cent 

 of viability into consideration, supply nearly 21,000,000 fertile seed 

 per acre; this means that there are at least 450 seeds per square 

 foot of surface. While we realize that it is often advised to sow 

 twice as much seed per acre as here suggested, we contend that 

 this seeding is sufficiently thick if sown on a properly prepared
