are other formulations of Krilium for pro- 
fessional use in greenhouses and formula- 
tions for highway engineers to use in 
erosion control. Each has been prepared for 
maximum effectiveness and ease of appli- 
cation. For some uses, tiny amounts of dis- 
persants are incorporated to make spread- 
ing easier; for other uses a small percentage 
of wetting agent is necessary for most rapid 
formation of soil crumbs; dyes are added to 
some formulations to distinguish the soil 
conditioner from fertilizer when the two 
are used together. The dyed formulations 
enable the user to see how well he has 
mixed the soil conditioner with other ma- 
terials, such as white lime or fertilizer. 
Monsanto recommends 5 lbs. of 
MERLOAM formulation for treating 40 square 
feet of garden soil to a six inch depth; or 
5 lbs. to treat 80 square feet to a three inch 
depth. These amounts will treat the hardest 
crusted soil. For poor soils —not badly 
crusted — 5 lbs. will treat up to 50 square 
feet to a six inch depth; up to 100 square 
feet to a three inch depth. Soils vary great- 
ly in different areas. The recommended 
amounts of MERLOAM are on the “‘safe side” 
... based on extensive tests by over 80 
scientific cooperators in universities, agri- 
culture experiment stations and commer- 
cial firms. 
The depth of treatment must be 
judged by the user. Six inch deep treatment 
is best for general gardening where deep 
spading would turn up untreated soil in 
succeeding years. Three inch deep treat- 
ment may be perfectly satisfactory for 
shallow-rooted plants such as lettuce, peas 
or spinach. A simple raked-in surface treat- 
ment—to a half-inch depth — will aid 
grass seed germination when putting in 
lawn. For rake-in surface treating, 5 lbs. of 
MERLOAM will treat 480 to 575 square feet 
to a half-inch depth. For establishing lawns 
or gardens — the user must judge how deep 
he wants his soil to be conditioned. 
MERLOAM treatment turns dense, 
hard soils into loose, spongy soil. Plant 
roots can grow and breathe. Water can 
percolate down to the roots. The treated 
soil becomes so easy to spade and cultivate! 
Plants can more easily break through loose, 
porous soil—so seeds germinate more 
readily. Good root growth takes place in 
the treated soil because root tendrils do 
not have to struggle through hard-packed 
soil. 
Fertilizers appear to work more 
effectively in the treated soil. MERLOAM 
treatment improves the environment for 
the plants and for the highly important 
soil bacteria. MERLOAM treatment does all 
that is structurally possible to turn a prob- 
lem soil into a good soil for growing. 
A plentiful supply of plant food is 
necessary to obtain good yields. MERLOAM 
treatment gives growing plants a good soil 
to live in — but it does not feed the plant. 
Fertilizers are needed to nourish plants. 
Consequently, when MERLOAM is_ used, 
the regular fertilizers should be used too. 
Plants cannot thrive in a light airy: soil, 
even with plenty of water, if there is not 
enough plant food present in the soil. For 
the greatest success with your garden, be 
sure to improve the soil structure and use 
enough fertilizer to feed the growing 
plants.
