    <p>The nitrogen status of Turkish soils for winter wheat production has been studied in a number of areas of Interior Anatolia. Nitrogen fertilizer increased the yield of winter wheat, if moisture or phosphorus were not limiting factors.<br> Certain dangers involved in substituting nitrogen fertilization for the summer fallow are apparent. If soil moisture is in short supply, nitrogen fertilization of the wheat crop may increase vegetative growth, rapidly deplete soil moisture<br> and depress grain yields. High levels of soil nitrate may depress availability of soil phosphorus to wheat.</p&gt
