pH is an accurate assessment of acidity chemically. It, by itself, isn’t a good way to monitor acidity biologically. We look at the pH:CEC Ratio. The formula is:
pH:CEC Ratio = pH/CEC + ( (OM – 2) /100) ) . A ratio above a .4 is conducive to microbial life and the addition of our microbial rich program.
If we are below a .4 on the pH:CEC ratio one of several things needs to happen.
Soils with magnesium above 17% base saturation are generally tight and compact easily. We have seen a benefit of applying Gypsoil.
On organic production.
Chloride is an indication of how well water is percolating through the soil. Monitor chloride levels to determine where compaction is at:
The above basic principles need to be addressed before truly entering a microbial program. Biology is a powerful force, but it needs an atmosphere in which to live.
The program is centered around structured calcium (calcite) and biology (manure). If you have manure, that is where we start. If you don’t, we provide it in the form of our Living Carbon product.
We start out with a 500 # application of Calcite Turbo S (CTS) or 275# of Organic CTS on all manured or compost-applied soil. Ideally, top applied manure or compost should be worked into the soil within 24 hours to limit carbon burn off. Our rate recommendations are as follows.
Liquid Dairy or Beef
Dry manure, compost, or poultry manure
Soil CEC 1-5
Soil CEC 6-8
Soil CEC 9-35
Living Carbon is the product we use when there is no owned manure. Living Carbon brings in both the biology and the structured calcium in one package. The rate will vary between 500 and 1000# per acre. It is essential that Living Carbon is either applied onto a cover crop or worked into the soil within 24 hours. It is vital that Living Carbon is not sitting on bare soil surface for longer than 24 hours. On all soils, but particularly low CEC soils (under 9), we recommend the use of a cover crop. This will enhance organic acids and soil biology.
Crop specific recommendations
Corn planting depth should be 2”
Take compacted areas and continuous corn on corn into consideration with nitrogen recommendations.
|TKN||Yr 1 Credit||Yr 2 Credit||Yr 3 Credit|
On Organic Corn
Beans should be planted at 1 ¼”.
