SPENT MUSHROOM MANURE 
Spent Mushroom Manure is real stable manure to which 
has been added 20% of rich top soil and then used to grow 
one crop of Mushrooms in the huge limestone caverns at 
West Winfield in Butler County. The heat of fresh manure 
is gone, but the organic content and fertility of good barn- 
yard manure is retained. 
The high organic content, almost five times that of top 
soil, is quite valuable in loosening heavy soils and increas- 
ing the moisture retention value. It is a long time source 
of mineral elements which are released gradually through 
decomposition into the soil. 
New studies prove that organic plant foods such as 
Mushroom Manure are absolutely vital in growing crops 
for human consumption. They claim that vegetables grown. 
without organic elements are almost valueless in supply- 
ing the needs of our body. 
A two-inch layer of. Spent Mushroom Manure mixed 
with clay excavation soil will produce a good lasting turf. 
This makes a much lower cost lawn than the hauling in of 
some low grade so-called top soil. This has been proven 
over and over again. It will produce a good lasting turf 
almost weedless. | 
For use on a vegetable, or flower garden we recommend 
from two to four inches spaded into the soil. A generous 
application will supply your garden with ample plant food 
for a long time. it loosens the soil, retains moisture and 
promotes growth. For mulching, or placing around any 
established plants, we recommend from one to two inches. 
For roses, it should be placed down in the bed on planting 
and then use some to mulch them every fall for winter 
protection. As a top-dressing for lawn either in the fall or 
winter, we recommend from %4 to ¥% inch. It is also used. 
by many gardeners to cover newly seeded lawns to keep 
them from drying out after seeding. 
Spent Mushroom Manure lacks the filth, odor and dis- 
ease spread in ordinary stable manure for it is sterilized 
before entering the Mushroom growing plant. This pro- 
cess also kills nearly all weed seeds found in ordinary 
barnyard manures.
