AGUICU LTURF OF JACKSON COUNTY. 
It should be remembered that most acid soils are also dificient 
in available phosphorus, but applying lime will not add to the 
total amount of phosphorus in the soil. The need of phosphorus 
may be so great that but little result will be secured from lim¬ 
ing until phosphorus is also added. Frequently the application 
of phosphorus alone to an acid soil will result in larger in¬ 
creases than the uses of lime alone, and for this reason it is 
important that both deficiencies should be corrected to secure 
the most economical production. 
THE USE OF FERTILIZERS 
We believe that most of the nitrogen needed for plant food 
by Wisconsin crops can best be secured through the growth of 
legumes and the use of stable manure. Since the legumes 
require a good supply of available phosphorus, this ele¬ 
ment should be applied by the broadcast application of phos¬ 
phate when seeding down to a legume whenever needed. This 
phosphorus in part becomes available along with the nitrogen 
of the legume to the succeeding crop of corn, potatoes, sugar 
beets, tobacco, etc., all of which on upland soils at least should 
be grown in rotation with legumes, or else on manured land. 
Only such additional amounts of phosphorus and potash should 
be applied to these special crops as are needed. These can then 
be applied in the hill or drill, if desirable. 
Peat and muck soils are abundantly supplied with nitrogen 
which can be made available by proper treatment but are prac¬ 
tically always low in potash and freqeuntly in phosphorus, and 
even sometimes in lime as well. 
Only such amounts of nitrogen should be purchased in com¬ 
mercial fertilizers as are needed to supplement the home grown 
supply. Such supplementary nitrogen should ordinarily be in 
immediately available form and be used to encourage early 
growth. Where it is desired to use a fertilizer carrying nitro¬ 
gen, it is highly important that this fertilizer be applied with 
a fertilizer attachment on the planter or in such a manner that 
it will come within the root feeding radius of the plant. Fer¬ 
tilizer attachments are being used for the application of fer¬ 
tilizers for potatoes and corn. For sugar beets the fertilizer 
should be applied at the time of planting the crop with a regu¬ 
lar fertilizer beet drill. Fertilizers for tobacco and cabbage 
are usually applied broadcast previous to setting, athough it has
