Grain crop producers continue have interest in P and K fertilizer placement for several reasons. Issues include: (1) the need at high soil test, (2) alternatives to 2×2 because of planter attachment cost, (3) fertilizer use efficiency, (4) convenience/time limitations, and 5) potential yield benefits. Research has demonstrated that banded placement methods enhance the efficiency of nutrient use and can increase yield. This observation appears to be more important in high residue management systems where nutrient applications are not routinely incorporated. Research conducted by this author has demonstrated increased P and K uptake and yield where the planter 2×2 placement method is used compared with broadcast (Wolkowski, 2000; 2003). Response tended to be greater in no-till relative chisel because soil and environmental condition of the seedbed under no-till resulted in reduced early season plant growth and nutrient uptake.
