S. Iowa | Here are my results on one farm:
Organic matter 3.5-4.2
Phosphorus 6-19 ppm
Potassium 84-150 ppm
Magnesium 366-525 ppm
Calcium 2300-2800
PH 5.9-6.0
Buffer index 6.6
Cation Exchange Capacity 18.2-20.8
Base saturations:
K 1.0-2.1 %
Mg 17.1-18.9%
Ca 63.9-64.7%
H 15-17.0%
These are gara, armstrong, mysyic, clay loams with 30-60% clay content. Corn and soybeans are no-tilled, with average or better results on below average soils. Beans did between 27 and 37 bushels this year and the bean stubble currently has a good cereal rye stand growing as cover. Corn did 115 last year while county average was below 110. Current plan is to no-till corn next year. How would you manage these soils and what would you recommend? Pell lime? Ag lime? South central Iowa. Thanks!
