A software model for precision agriculture for small and marginal farmers

Precision Agriculture (PA) was originally developed to address variability in soil and crop parameters for large-scale agriculture in developed countries. The general concepts of PA can also be adapted for farm-based agriculture for small and marginal farmers in Developing Countries. This approach is characterized by a farmer-soil-crop database acquired from the field, crop calendars provided by agricultural experts, real-time acquisition of parameters such as temperature and rainfall through sensors, and an analytical model that simulates the crop calendar using static, semi-static and dynamic inputs, leading to farmer- and crop-level support advisories delivered through devices such as mobile phones and tablets.
