pH is something we may take for granted,
but it makes a big difference in plant health and its fruit.
Have your soil tested ($15) by mail at the U of M.
There are three main groups of pH plants in Minnesota
Group 1: Alfalfa, Alsike Clover, Apples, & Asparagus
pH of 6.5 is best, add Lime to raise pH.
Group 2: Birdsfoot Trefoil, Buckwheat, Corn, Edible Beans, Grapes, Grass Seed or Hay, Peas, Red Clover, Barley, Wheat, Oats, Raspberries, Strawberries, Sugar Beets, Sunflowers, Sweet Corn, & Vegetable Crops
pH of 6.0, Add lime to raise pH
Group 3: Potatoes, Grass Sod, Blueberries, & Wild Rice.
Prefer acid soils, Add Sulfur. Approx. 0.8 lbs/100 sq. ft. will lower pH 1 unit. in sandy soil
Approx. 2.4 lbs/100 sq. ft. will lower pH 1 unit. in loam or silt loam soil
