Suggestions. — An abundance of potash and phosphoric acid is 

 desirable in order to secure a strong and plentiful growth of cane. 

 Moderate acting forms of nitrogen are preferable for the most part.

Suggestions. — Buckwheat can supply itself from forms of plant 

 food not readily available. It is often grown on the poorer soils 

 of a farm on this account. Frequently phosphoric acid alone 

 gives marked results. Large application of nitrogen must be 

 avoided, as this produces a large growth of straw, with little grain.
