HUMUS 
Cultivated and Prepared 
Invariably the addition of humus or similar organic ma- 
terial will improve the physical condition of soil. Careful 
tests of many products resulted in the selection of this 
| cultivated humus. Its advantages are many—it binds 

sandy soils—loosens clay soils and is extremely useful 
as a mulch or top dressing. Furthermore, it increases 
soil bacteria and releases the necessary nitrogen essen- 
tial to plant growth—stimulates root growth—provides 
drainage and prevents water logging, but conserves 
moisture. Being well seasoned and correctly prepared 
it is ready for immediate use. 
New Lawns 
Prepare the land carefully by thorough drainage and 
deep cultivation. Break up all lumps, remove all sticks, 
stones and other foreign matter. Broadcast humus over 
the entire area to a depth of one-half inch. Slightly 
heavier application for poor land. Add Turf Builder 
as directed. Work the humus thoroughly into the top 
3 inches of cultivated soil, rake smooth, and your soil 
is then ready for seeding. 
Established Lawns 
Mow entire lawn fairly close. Rake both ways vigor- 
ously with bamboo or fine steel rake to remove all 
dead grass and foreign matter. Loosen surface with 
a heavy spike tooth roller. Spread humus to a depth 
of % inch, mix Turf Builder, and brush into the soil 
so that it penetrates down to the roots. Where the 
spots are very barren replace poor soil with equal 
amounts of humus and topsoil, add the proper quantity 
of Scotts’ grass seed, roll and water. 
Benito and Flower Borders 
Apply humus 1 to 2 inches thick depending on soil 
conditions, and work thoroughly into the soil imme- 
diately surrounding the plants, to a depth of 4 to 6 
inches. For new plantings several shovelsfull thoroughly 
incorporated with the soil.in each hole will prove very 
beneficial. 
GENERAL SOIL IMPROVEMENT 
To increase the organic content of average soil by 1% 
which is the minimum amount recommended, apply 40 
yards of cultivated humus to one acre and thoroughly 
mix with the top 6 inches, of soil. Such an application 
is approximately 1/3 of an inch thick using one bushel 
of humus to fifty square feet. Naturally a clay soil 
will need a heavier application.
