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?

Match the patient care situation to the appropriate core process in the patient care process cycle.

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

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

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?  

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?

Example of plant mobile nutrients:

If you are sampling 11″ corn plant for nutrient deficiencies, you collect what part of the plant?
