| I’ve seen Mississippi sandy loam yield 260 average and touch 290. Heavy dirt doesn’t have that potential. I think it’s nutrient tie up. 200 is a good average here tho. Heavy dirt just blows. I did upper 70’s into the 80’s on beans last year on heavy dirt tho. hipping up on a taller row seems to help with the heavy dirt and surge irrigating. I never like to irrigate for longer than 12 hrs no matter how far the water has gotten. I’ve often wondered if the high mag concentration is the reason corn doesn’t do better. Iowa is numero uno in corn and that’s where they mine gypsum. Our soil needs gypsum. I wonder if that’s why Illinois and Missouri grow more beans. Being on the east side of ms river causing higher mag concentration. this is 100% pure speculation. The high row would also help leach the mag down here. Also I always do every other row when irrigating.

Why are Corn Yields so poor in the Mississippi Delta?
