Year Analyzed


State

If no State is selected, all will be searched, including those samples that do not have an assigned State.


Moisture Designation

If no Moisture Designation is selected, all will be searched, including those samples that do not have an assigned Moisture Designation.

* Based off of Total Solids/Moisture content and used MidWest Plan Service definition: if 0-4% Total Solids="Liquid", >4-10% Total Solids="Slurry", >10-20% Total Solids="Semi-solid", >20% Total Solids="Solid". If a sample has no Total Solids or Moisture level, used lab Manure Type designation of Liquid, Solid, Slurry, or Semi-solid. If a sample has no Total Solids, Moisture, or Manure Type, this category was left blank.


Manure Type

If no Manure Type is selected, all will be searched, including those samples that do not have an assigned Manure Type.

* Lab-designated


Bedding Type

If no Bedding Type is selected, all will be searched, including those samples that do not have an assigned Bedding Type.


Storage Type

If no Storage Type is selected, all will be searched, including those samples that do not have an assigned Storage Type.
