drated manures, cow, horse, sheep or poultry, are ex- 
cellent substitutes. Apply about 200 ibs. to 1000 sq. ft. 
Cotton Seed meal and Soy Bean meal can also be 
utilized. Apply about 100 lbs. ‘to 1000 sq. ft. Humus 
improves the physical condition of the soil, its plant 
food deficiencies can be overcome by larger applica- 
tion of fertilizer. Apply the Humus about | inch thick. 
Humus is relatively inexpensive. It can be supplied 
by the Doughten Seed Company dealers. 
In addition to supplying the organic matter needs on 
poor soils, plani food in the form of commercial ferti- 
lizer should be added; about 25 to 50 lbs. per 1000 sq. 
ft. Fertilizers are supplied in various formulas, Consult 
your dealer for the best for this purpose. 
LIME — Many experiments have proven that lawn 
grasses will not thrive on strongly acid soil. The turf 
under such conditions fails to respond to fertilizer 
treatment and is susceptible to injury from disease, 
insects and drought. Lime should be thoroughly 
worked into the seedbed as it is prepared. The fol- 
lowing quantities of ground limestone on the basis 
of 1,000 square feet of lawn are suggested: 
Sandy soils ... » BYU) YAY Wee 
Loam soils .......... 75 to 100 lbs. 
Clay soils ... 100 to 125 lbs. 
If hydrated lime is used apply the lower figure in each 
case since this type of lime is more concentrated. 
GRUB AND WORM PROOFING THE SOIL—Add 10 lbs. 
of 10% DDT or its equivalent per 1,000 sq. ft. of lawn. 
APPLYING THE MATERIALS—The organic matter, fer- 
tilizer, lime and DDT may be applied together to the 
soil surface. They should then be thoroughly mixed 
into the upper 4 to § inches of soil at least 1 week 
before seeding. 
PREPARATION OF THE SEED BED—Grass seeds used 
for establishing lawns are small and require intimate 
contact with the soil particles for satisfactory germi- 
nation. This requires a fine, well compacted seed bed 
which is free from clods and lumps. For small areas 
a hand cultivaior is an excellent tool for pulverizing 
the soil. On larger areas a disc harrow followed by a 
weeder may be used. It is desirable to continue sur- 
face tillage operation over a period of time so as to 
promote the germination of weed seeds which will be 
destroyed by the tillage operation. 
This is followed by a final grading and a smoothing of 
the surface in preparation for seeding. On small areas
