Estimating Field Loss & Hail Damage 03/09/05 10:10:47 AM
Estimating Field loss and Hail Damage
To estimate field loss, randomly mark off a square foot and count the number of beans in that square foot. Accuracy will increase with the higher number of samples you include in your average. refer to the chart below to convert the beans per square foot in lbs./acre lost.
Beans per Square Foot Navy Beans lbs/acre lost Pinto Beans lbs/acre lost
4 67 133
6 100 200
8 133 267
10 167 333
12 200 400
14 233 467
16 267 533
18 300 600
20 333 667
22 367 733
24 400 800
Crop damage caused by hail will depend on the intensity and duration of the storm, size of the hail stones and the stage of plant development. Sever hail damage can delay plant maturity. Hail damage at earlier stages of plant development gives the plant more time to recover from the damage. More recovery time could result in less yield reduction
To measure ground sped of any machine, walking along aside for 20 seconds, counting your three foot steps and divide by 10. this equals MPH.
16.5 ft =1 rod 5280 feet = 1 mile 43,560 sq feet = 1 acre
