Keys to Successful Integration of English and Math skills into the Agriculture course
*Make it a priority and not just busy work. If you are positive about this more than likely
your students will stay positive.
*Make it fun and relate to your current topics in class.
*Make the real-life connection. Answer the famous how am I going to use this in life
question.
*Don’t do this stuff every day. You don’t want your class to be known as another math or
English class.
*Make the connections as to why these skills are important (Ex. success in FFA contests,
getting a part-time job, graduating with a Core 40 or Honors, making it in the real world
on their own, not having to take remedial courses anymore, etc.)
*If you practice a skill include it in your quiz and/or test. Make it valuable to the student
for the class as well as personally.

_43,560___________________________ square feet are in 1 acre.
Practice Calculating Pesticide Formulations
Problem 1:
Formula:
Work:
Solution: 1 cup/ 49 15/16 gallons (~50 gallons)
Problem 2:
Formula:
Work: 9 ounces/ 2 gallons, 119 ounces (~3 gallons)
Individual Practice Calculating Pesticide Formulations
1. A label requires you to use 3 ounces of pesticide per 50 gallons of spreader oil. You have
determined that you need approximately 500 gallons of spray to manage your pest
problem. If the pesticide is sold in a 10 ounce bottle, how many bottles do you need to
buy?
4
2. You just filled up your 25 gallon spray tank with water. You hope to spray crossbow at a
rate of 1 pint per 100 gallons. How much Crossbow do you need to add to your tank?
3. You must mix 25 pounds of a dust insecticide with 75 pounds of granules to safely apply
it to your land. How many 50 pound bags do you need to purchase if you want to mix the
insecticide with 225 pounds of granules?
Calculating Pesticide Coverage
Pesticide coverage is the volume that can cover a specified area of land.
The three factors that effect coverage are:
1. Speed
2. Volume
3. Rate
Speed is dependent on these 5 factors:
1. Tractor Gear
2.
Tractor RPMs
3. Make/Model of Tractor
4. Lay of land
5. Safe Operating Speed
Practice Calculating Pesticide Coverage
Problem 1:
Formula:
Work:
Solution: 2 lbs/acre = 50 pounds/2 pounds = 25 acres
Problem 2:
Formula:
Work:
Solution: 2 quarts/ ¼ acre = 2 x 4 = 8 quarts/acre, 8 quarts/4 = 2 gallons = RIGHT AMOUNT
5
Problem 3:
Formula:
Work:
Solution: 120 ft x 40’ = 4800 ft2/minute, 650 ft2/minute/43,560 ft2 = 0.11 acre/minute
0.11 x 60 = 6.6 acres/hour
Problem 4:
Formula:
Work: 75/100 = 0.75 x 2 = 1.5 ounces
Individual Practice Calculating Pesticide Coverage
1. Your nozzles on your sprayer will deliver chemical at a rate of 1 pint of chemical per
square foot per minute of travel. Your spray boom has 15 nozzles and your tank is 500
gallons. How long will it take the applicator to run out of spray?
2. You can apply ½ pound of 10-10-10 fertilizer per acre when you have the tractor in C1,
1500 RPMs. If you put 200 pounds in the spreader, how many acres can you cover?
3. If a bottle of herbicide indicates that it should be sprayed at 14 gallons per acre, and your
sprayer will deliver 7 gallons per acre, how would you go about getting the correct rate?
4. You are traveling at 75 feet per minute with a 30’ spray boom while spraying Malathion
EC. You are delivering the spray at 12 gallons an acre. How many acres will you cover
in an hour?
5. The label for 2-4,D calls for 3 ounces per quart. You want to mix up enough spray to fill
your 3 ½ gallon back-pack sprayer. How much 2-4,D should you put in the tank?
