If you had one wheel barrow of poop (200 lb) to use on your large 1/2 acre garden, would you get it from the cow barn, pig barn or chicken coop for your sweet corn?

The lime reaction, the amount of time required for the pH to reach target levels, is generally:

The optimum (target) pH for a soil depends on the crops that will be grown.  Once a desired pH is reached through liming, the pH will remain at that level for a relatively long time.  An exception to this is ___________________ soils which tend to need lime more frequently at lower rates.

What are common grid sample sizes in acres?

Every field is completely uniform in it’s lime requirements.

Formulas are used to calculate lime requirements to bring soils to target levels.  The major variables used in these calculations is target pH for the crop, buffer pH (BpH) which is derived from a soil test, and the neutralizing index (which is unique to the liming material.)   Buffer pH indicates which of the following?  

What color does the Phosphorus deficiency routinely appear as in deficient crops?

How much 9-23-30 would you apply per acre if you wanted 27 units of N per acre for a starter on your corn crop?

When taking a soil sample, often it is 7-9″ in depth, as it is the approximate zone of root activity.

Which areas should you avoid sampling when you are probing soil samples?
