This mixture of clover grass contains 40°/o of Red clover. The absolute amount of pure and 
germinating red clover seed required to cover an acre is 15.84% lbs. (see table 1): an addition of 10 °/o 
17.42 >< 40 
makes 17.42 lbs... The mixture should then contain Sa ae lbs. == 6.97 = nearly 7 Ibs. of pure and 
germinating seed. Commercial seed has been taken as containing 85 °/o pure and germinating seed, therefore 
7 x 100 | ya 
ene ae lbs — 8 lbs., nearly, of such commercial seed is required. The other calculations are made 
in the same way.

Protective crop. The best preparatory crops for all fodder grasses and clovers are such as leave 
the field well manured, and as clean as possible. These conditions are best fulfilled by a well man- 
ured root-crop. 
Grasses as well as clovers require a fine tilth, because, without this, many of the seeds fall be- 
tween clods and lie too deep, so that the young plants which spring from them are lost. 
The covering of the seed ought to be very slight, for the reason that many grasses, especially 
those of the finer kinds, will not grow when at all deeply covered. On heavy humid soils no covering 
is necessary, and rolling suffices; on light dry soils, the seed may be covered by means of a light harrow, 
In general the spring months from April to the middle of June, are most favourable for sowing ; 
Autumn sowing is, however, often resorted to, but the results are less satisfactory. 
Sowing is performed by hand, or by the clover-drill, which can be used for all kinds of grasses 
except False oat-grass. 
Grasses and Clovers are usually sown in a protective crop, very frequently in winter-wheat, in 
the months of February or March. At times, spring-wheat or cereals to be cut green (oats or rye) 
form the protective crop. 
Full information on all these points is given in Stebler’s work on »The Mixing of Grass-seeds« 
already referred to.
