Abstract A theory was developed enabling calculation of the effect of any placement method of fertilizer on yield if the effect of one method is known.<p/>This theory was based on the following established facts. The reactions between soil and fertilizer rate are the same for broadcasting and placement methods if the concentration of fertilizer is the same. A definite relation exists between yield and uptake of the nutrient, which is in general independent of the method of placement. As an approximation, the ratio between the increases in nutrient uptake with two methods of application depends only on the ratio of the volumes of soil fertilized to the same concentration.<p/>
