The amount of nitrogen which is usually applied in mixed fertilizers used in the hill fertilization of corn is only a small part of the total nitrogen necessary to produce a crop, hence a question arises regarding the necessity of adding any nitrogen. More experimental data must be secured before an answer can be given, but some information may be obtained in regard to the value of mixed fertilizers by determining whether the increased rate of growth of the tops of young plants which have been hill fertilized is due merely to the fertilizer applied or whether a larger root system has been produced. If the latter has occurred, the plant will obtain more food from the soil, and the growth and maturity of the crop will be hastened.
