The objectives of this research are (1) to determine the effects of tillage/fertilizer placement [no-till (NT)/surface broadcast or strip-till (ST)/deep banding], monoammonium phosphate rate [0, half the recommended rate, and the recommended rate], and the presence and absence of two enhanced phosphorus efficiency products [Avail[copyright] (Specialty Fertilizer Products, Leawood, KS) and P2O5-Max[copyright] (Rosen's Inc., Fairmont, MN)] for corn conducted at Novelty and Albany, MO; and (2) to determine the effect of lime application (0 and recommended rate), P source [non-treated control and a broadcast application of diammonium phosphate or triple superphosphate], and the presence and absence Avail[copyright] or P2O5-Max[copyright] for corn conducted at Novelty and Portageville, MO. The two P enhanced efficiency products did not consistently increase corn grain yield, including apparent P recover efficiency, in interaction with several fertilization, liming, and tillage practices at the sites and environmental conditions evaluated in this research. Triple superphosphate treated with Avail[copyright] increased P uptake 8.6 kg ha-1 compared to the non-treated control at Novelty, but not at Portageville. Strip-till/deep banding increased plant populations 15,500 plants ha-1 at Novelty and 3,500 plants ha-1 at Albany compared to NT/broadcast. Yields increased 1.57 Mg ha-1 with use of ST/deep banding over NT/broadcast at Novelty. The recommended amount of lime increased grain yields 0.77 Mg ha-1 at Portageville.","abstract_html":"Farmers are interested in the use of enhanced efficiency phosphorus (P) fertilizer applications or treatments.
