Method of fertilizer application RECOMMENDED methods of applying fertilizer f o r annual winter grazing crops in the Southeast are generally of two types: (1) drilling to a depth of 2 to 4 inches in rows 7 to 9 inches apart on prepared land, or (2 ) broadcasting on the surface and mixing with the top 3 or 4 inches of soiI by disking. The latter method results in intimate contact between soil and fertilizer and therefore favors the fixation of applied phosphorus. On soils low in this nutrient less fixation and therefore increased availability to applied nutrients should be obtained by banding as compared to thorough incorporation. Also, early stimulation of the seedlings which may be accomplished best by banding the plant nutrients, is advantageous where early winter grazing is desired. If a portion of the plant population is not within effective reach of the banded fertilizer, however, less efficient utilization may result. This concept is not new, but the advent of radio-isotope techniques provided a new tool for making an accurate evaluation of the relative efficiency of the two methods of application.
