soils. In such cropping it is usually a large development of fruit, 
roots or tubers that is desired rather than a rapid succulent vege- 
table growth. Also the crop has a much longer time to grow than 
early garden crops and so can use more slowly available plant 
food. This applies to the growing of such crops as potatoes, 
onions, late cabbage, and tomatoes and other crops used for can- 
ning. 
In case of early garden crops where large amounts of soluble 
fertilizers are needed, they can be used more profitably when the 
soil is well supplied with organic matter than otherwise. These 
quickly growing crops do not make very eflicient use of the slowly 
available forms of plant food in the soil, and organic matter makes 
the soil more retentive of soluble nitrates and potash; making 
their use more profitable. 
Fertilizers for muck sotls 
Tn this state muck land is used mainly for truck growing rather 
than market gardening, and fertilizer recommendations are made 
with that in mind. Where muck consists mainly of organic mat- 
ter, as is usually the case, potash is the first important constituent 
of fertilizer to be used, and may be applied at the rate of 100 to 200 
pounds per acre of muriate or sulphate, or 300 to 600 pounds of 
kainit. When potash is not available manure will take its place 
to some extent. Manure is always profitable on muck land, al- 
though it might at first be supposed that on account of the high 
nitrogen and organic matter content of muck this would not be the 
case. But the fresh decomposing organic matter of manure stimu- 
lates further decomposition of the muck and makes nitrogen 
available. Phosphorus is second in importance to potash on muck 
soils, but more necessary than additional nitrogen. Where com- 
mercial fertilizers alone are used on muck a mixture may consist 
somewhat as follows: 
200 Ibs. nitrate of soda or dried blood 
500 Ibs. acid phosphate 
200 lbs. muriate or sulphate of potash 
The mixture will analyze approximately 3-8-10 and may be used 
at rate of 500 to 1500 pounds per acre, depending mainly upon 
acre value of the crop to be grown.
