use of the succeeding alfalfa in any case. Acid phos- 
phate works well with crimson clover; put on 200 
pounds of it per acre, choosing always a grade 
analyzing a good percentage of available phosphoric 
acid. It likes a good seed bed too. Mix with 
it 10 per cent of alfalfa, and if the land has never 
had on it either alfalfa or crimson clover, get some 
infected earth from an old field of each of the plants. 
Infecting a Field—One can use rather a small 
amount of earth and get good results in inoculat- 
ing a field if he does it in the right manner. Let 
him get as little as 100 pounds of earth from where 
crimson clover has been grown and 50 pounds of 
earth from an alfalfa field or a sweet clover patch 
and mix these together and pulverize them well. Do 
this away from the sun. Then mix the crimson 
clover seed, say 15 pounds and say 2 pounds of 
alfalfa seed with the 150 pounds of infected soil. 
Sow this altogether on an acre of land. Sow it 
if you can late in the day, or at any event follow 
the sower with a harrow that will at once stir the 
land and cover seed and infected soil. Sunlight is 
fatal to inoculation. 
The result will be that both sorts of plants will 
grow well together and the alfalfa plants, while 
much more feeble in growth than the crimson clover, 
will yet hold its own pretty bravely and will be- 
come inoculated and thus will prepare the land for 
a single seeding of alfalfa next vear.
