Notes from Soil Class, pH

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

Permaculture and Polyculture Consulting and Design
Getting to know your property, the plants you have and those you can grow, is a fulfilling endeavor. With most I am the steward of the land. I give them good soil biology and they do the rest. If I group them in cohesive plant communities, they respond with greater yields. If I encourage the micro-organisms (Fungus and bacteria) , the roots obsorb more nutrients making a pest and disease resistant plant. A stronger plant that gives us more organic food and takes less energy.
