ORGANIC METHODS 
FOR QUALITY CROPS 
It is universally recognised 
that organic matter in some 
form must be incorporated in 
the soil if fertility is to be 
maintained. 
Animal manure has_ been 
used for thousands of years 
for this purpose and where it 
is available in sufficient quan- 
tities there is no need to loox 
for other ~matenals =Beiore 
use it should be treated with 
O.R. as described on page 3, 
thus greatly increasing its 
fertilising value. 
Except, however, where 
mixed farming is_ practised, 
there is always a_ serious 
shortage of animal manure. 
Fortunately, well-made com- 
post is a complete substitute 
and the introduction of QO.R. 
has not only quickened the 
speed of manufacture but has 
also increased the value of the 
finished material, particularly 
as regards its nitrogen content. 
The rules of compost mak- 
ing are elastic but care taken 
in the preparation of the heap 
will be rewarded with a better 
result. 
General Rules for 
Building Compost Heaps 
To decompose vegetable 
matter requires, among other 
things, the correct degrees ot 
moisture content and a supply 
of air. , 
To save transport, the site 
for the heap should be as near 
the ground on which it is to 
be used as possible and _ pre- 
ferably in a position sheltered 
from cold drying winds and 
dripping trees away from areas 
where surface water accumu- 
lates. In very hot climates it 
is desirable to make use of 
shade to prevent quick drying 
out. 
Materials To Use 
The following materials can 
be used: Straw, digested 
sewage sludge either mixed 
with vegetable matter or alone, 
town waste, weathered saty- 
dust, bracken, seaweed, road 
sweepings (tar free), grass 
clippings and many _ crop 
residues including potato, 
peas, tomatoes, vines, corn
