Camp Douglas Wi. 40miles nw of wi. dells | We have heavy red clay to sand in every field here, in 2011 we got new planter, put Dawn GFX row cleaners on, left outside row run one Dawn curvatine and one standard rubber, right outside row run two Dawn curvatines. With the two rows side by side, we evaluated every soil type, ended up in 2012 putting one Dawn curvatine and one standard rubber on each row unit. With one and one all soil types had better emerges than double rubber wheel, but double Dawn curvatines was to agressve and pulled out some seed on the lighter soils , on heavy soils double curvatines worked very good. That's here on our farm. Dan |
