This report contains the results of fertilizer experiments conducted in 13 counties in South Dakota. Experiments were located in representative soil and crop areas of the state. The objectives of those experiments were to:
1. Determine optimum fertilizer rates and ratios.
2. Evaluate two methods of application on the yield of small grain.
3. Determine the effect of time of application.
4. Appraise the influence of soil types and previous management on fertilizer response.
5. Ascertain the residual effects of commercial fertilizer.
In general the weather conditions in spring and early summer were favorable for small grain. The high temperatures and deficient rainfall in July reduced yields in some areas. For corn the early season temperature and moisture conditions were favorable, but the low rainfall in July caused a reduction in yield in some counties.
