Fertilizers and Soil Conditioners 
There are probably no more important and no more 
frequently neglected gardening functions than proper 
fertilizing and soil conditioning. A definite distinction 
exists between fertilizing and soil conditioning. A fer- 
tilizer must perform either exclusively or as its principal 
function the feeding of plants by supplying chemical 
nutrients to the soil from which the plant feeds. The func- 
tion of the soil conditioner is to produce suitable soil 
texture. For example, (the use in) recommended quanti. 
ties of WILSON'S, or similar formulas, feed the plants 
by supplying nitrogen, phosphoric acid and potash in 
the order of and in the percentages shown by the 
three figures of the fertilizer formula. On the other 
hand, the use of peat moss, humus, etc., binds loose, 
sandy soils and breaks down soil particles in heavy, 
clay soils but is of little importance in supplying the soil 
with plant nutrients. There are, however, organic fer- 
tilizers such as Bovung, Sheep Manure, Poultry Manure 
and Driconure which serve the two-fold function of as- 
sisting in proper soil conditioning as well as offering 
all three of the principal fertilizing elements. 
LIME — VALUABLE CONDITIONER 
There is no broad, all-encompassing answer to your 
particular fertilizing problem since both soil texture and 
soil richness varies with location, past fertilizing prac- 
tices, etc. If your soil is heavy, clayey and inclined to 
form hard crusts, the use of sand, lime, limestone, gravel, 
humus or peat moss will modify and ultimately correct 
the condition. The same ingredients with the exception 
of sand and gravel will help bind loose, sandy soils. 
Lime and Limestone are of particular value because 
lime is not only a soil conditioner, but makes plant 
foods available more rapidly and acts as a corrective 
for excessive soil acidity. Lime, however, should not be 
applied indiscriminately either to lawns or gardens. The 
existence of soil acidity may be determined by a chem- 
ical test and lime applied to acid areas in quantities 
indicated by the test. You can make such tests yourself, 
economically and easily, by using the Sudbury Soil Test 
Kit. Similar soil tests should be made to determine your 
fertilizer needs, 
For general use a complete chemical fertilizer or an 
organic fertilizer is recommended. Either of these or 
similar fertilizers may be incorporated with the soil 
when the lawn or garden site is dug, may be used as 
“side dressing’ on lawns and flower beds. Most of 
these fertilizers may also be used in liquid form. 
CONCENTRATED PLANT FOODS 
Plant foods, such as Hyponex, are highly concen: 
trated and are always diluted in water before applica: 
tion. Such fertilizers are of particular benefit in stimu 
lating growing plants and in transplanting seedlings. 
When used in transplanting, such diluted fertilizers are 
known as “starter solutions” because, by minimizing the 
effects of transplanting shock to the plant, they get the 
seedling off to a good start in its new location. 
In addition to the many excellent commercially pre 
pared fertilizers and soil conditioners offered in our 
catalog, you can make your own fertilizer. By using 
Adco on your accumulation of garden refuse you can 
produce in your own plot enough fertilizer for the fol 
lowing season’s needs. Adco, by supplying the three 
important fertilizing elements, plus Vitamin Bi, forms a 
fertilizer of organic origin which acts efficiently as a 
soil conditioner as well as a complete fertilizer. The use 
of sulphate of ammonia and superphosphate applied at 
the rate of one-half ounce to the square yard and aug- 
mented by hardwood ashes and limestone will also fear- 
tilize and break down a compost heap of garden refuse 
but is less convenient to use than Adco.

ditioners under headings indicating their principal

One-Element Fertilizers (Fertilizers predominantly rich ip 
only one of the three fertilizer elements) 
Muriate of Potash Nitrate of Soda

Sulphate of Ammonia Cotton Seed Mea) 
Acid Correcting Concentrated Fertilizers 
Lime Limestone Hyponex - Kem - Plantabs 
One-element fertilizers are used to supply crop re 
quirements, to incorporate with other fertilizers or to 
supply soils deficient only in one element. Muriate of 
Potash and Hardwood Ashes, which are rich in potash 
are used for root vegetable crops such as carrots, beets, 
parsnip, etc. Cotton Seed Meal, rich in ammonia and 
potash, is ecellent for many grasses. Nitrate of Soda, 
a powerful nitrogen fertilizer, is frequently used as a 
side dressing on lettuce, cabbage, beans, etc., to keep 
the plants growing steadily. Aluminum and Ammonium 
Sulphate supply nitrogen and make soil acid and are 
excellent for use with Rhododendrons and other broad- 
leaved acid loving plants. Superphosphate, while some- 
times used independently, is more frequently incorpor- 
ated with other fertilizers to increase phosphoric acid 
content.
