These Crop Calculator Apps Really Add Up

Dozens of inexpensive or free mobile apps can make various aspects of farming incrementally easier to use. But where to find them?

Ignacio Cimapitti and Jeffrey Albers with Kansas State University have done a venerable job collecting and collating helpful agriculture apps into 10 categories. Most recently, they shared their findings from one of these categories – calculator apps.

These apps calculate any number of things, from planting, spraying, fertilizing, harvesting or yield estimation purposes. Here are their top picks.

1. Fertilizer Removal by Crop – Input crop and desired yields to see how much of various vital nutrients the crop will need.

2. Planting Population Calculator – Determine planting population and stand counts.

3. Pioneer Planting Rate Estimator – Determine optimum planting rate for DuPont Pioneer corn products.

4. Nebraska On-Farm Research Network – Enter treatments for individual fields, compare yield results and take in-season notes.

5. Canopeo – From Oklahoma State University, this app measures canopy cover.

6. KSUSoyYieldCalc – Estimate soybean yields based on plant population, pods per plant, seeds per pod and seed size.

7. Kansas Wheat Yield Calculator – Collect information about winter wheat fields to assess potential yield ahead of harvest.

8. Harvest Loss Calculator – Input number of seeds or kernels on the ground per square foot to determine harvest loss.

9. Harvest Test Weight Converter – From the University of Nebraska-Lincoln, determine shrink volumes, in-field yield estimates and total volume in grain bins or grain piles.

10. Corn and Soybean Advisor – These two apps from the University of Arkansas allow farmers to calculate nutrient rates, identify nutrient and water needs, and determine disease and insect pressures.
