Comparison of planters and fertilizer application systems for no-till corn
A project was conducted in response to difficulties being encountered with conventional fertilizer placement systems for corn on no-till planters. To overcome these difficulties, farmers have made various modifications to planters and fertilizer application systems. This project evaluated three recent developments in fertilizer application systems: (1) a cross-slot planting system developed in New Zealand which results in less soil disturbance than other no-till planters and places fertilizer closer to the seed row than a conventional side band (5 cm to side and 5 cm below) (2) a strip-band fertilizer application system developed at Guelph which places fertilizer in two strips, one on either side of the row and about 2 cm below (3) a coulter-strip fertilizer application in which the fertilizer is deposited on the soil surface in front of a fluted coulter. Experiments were conducted at two field sites in Huron Co. and Oxford Co. in 1990 and at three sites in 1991, one in each of Kent, Huron and Oxford Cos. The specific objectives of the study were: a. To compare the effectiveness of planting and fertilizer application using the cross-slot, strip-band and coulter-strip application systems. b. To compare the cross-slot planter with a conventional system under varying soil conditions.
