LIQUID ANIMAL WASTE CALCULATORS


NOTICE: While the information generated from this site is believed to be accurate, any actions taken based upon the results is the sole responsibility of the user.


The following calculators should be useful to anyone who applies liquid waste such as swine or dairy farmers. If you find these useful or if you find they are giving inaccurate results, please let me know. I am only half way through this project, but hopefully I'll have all of them in place soon.


Volume Of Waste Generated By Farm
Application Rate For Priority Nutrient
Acres Needed To Utilize Waste
Application Rate In Gallons Per Acre
Pounds Of PAN Applied Per Acre
Gallons To Acre-Inches
Number Of Waste Applications Needed
Precipitation Rate For Stationary Irrigation Equipment
Time Of Irrigation Operation
Precipitation Rate For Traveling Gun Irrigation
Application Volume(Depth) For Traveling Gun Irrigation
Travel Speed For Traveling Gun Irrigation

Application Rate For A Liquid Spreader


VOLUME OF WASTE GENERATED BY FARM

This calculator will compute the volume of liquid waste, in gallons, that your farm will generate.
Fill in the fields, then calculate:

Number of Animals on Farm:
Gallons of Waste per Animal per Year:

The farm produces gallons of liquid waste per year.

APPLICATION RATE FOR PRIORITY NUTRIENT

This calculator will compute the rate of priority nutrient, in pounds per acre, to be applied to meet Realistic Yield Expectation .
Fill in the fields, then calculate:

Realistic Yield Expectation per Acre:
Pounds Nutrient needed per unit of
Realistic Yield Expectation:

The rate of priority nutrient to be applied is pounds per acre.

POUNDS OF PAN APPLIED PER ACRE

This calculator will compute the amount of plant available nutrient applied in pounds per acre.
Fill in the fields, then calculate:

Waste Application Rate (gals/acre):
Lbs PAN Per 1000 gals of Waste:

pounds per acre of plant available nutrient was applied.

NUMBER OF WASTE APPLICATIONS NEEDED

This calculator will compute the number of applications necessary to apply the volume of waste to be utilized.
Fill in the fields, then calculate:

Total Inches of Waste Needed:
Inches of Waste per Application:

applications are needed to use this volume of waste.

PRECIPITATION RATE FOR STATIONARY IRRIGATION EQUIPMENT

This calculator will compute the precipitation or application rate for stationary irrigation equipment, in inches per hour.
Fill in the fields, then calculate:

Sprinkler Flow Rate (gpm):
Sprinkler Spacing (feet):
Lateral Spacing (feet):

The precipitation rate is inches per hour.
