The smartphone and tablet offer ready access to essentially any information you need. However, key apps available on the market can help you target your data use in new ways.

We’re sticking to apps that look at crop nutrition, though you’ll find a growing range of ag-focused tools coming to the market. Best way to find these is to type their exact names in the search box in iTunes or Google Play to get the right app for your device.

Crop Nutrient Deficiency Photo Library — What does a nutrient deficiency look like in a specific crop? The International Plant Nutrition Institute has come up with a photo app that shows different problems by crop. Got a boron deficiency in corn? You can see just what it looks like. The app is free (iTunes only).

Fertilizer Removal by Crop — Developed by the folks at Ag PhD, this app looks at how much “X” number of crop bushels will remove for nutrients. Designed for both iPhone and iPad, the app is free (iTunes and Google Play).

Nutrient Removal — The folks at the fertilizer company Mosaic have also come up with a nutrient removal app. This is a free app available in iPhone and Android format (iTunes or Google Play).
