Field Guide Apps for agriculture
These Apps compile information from several production topics such as soil fertility, weeds, insects, diseases, crop management, calculators, and more. The Corn and Soybean Field Guide (Purdue University) is a very useful App. The fplants App portrays diverse forage species and provides a guide to forage ID. The HortPlants (University of Arkansas) App provides an extensive photographic catalogue covering many plants of the Mid-South, such as trees, vines, ground covers, shrubs, and ornamental grasses, among others. A new App from Oklahoma State University (FieldGuide, Dr. Arnall) is worth downloading, with information on nutrient removal, deficiency ID, nutrient demand, and fertilizers.
