Agrisim optimizes farmers’ parcels and gives answers to the main questions "what to grow on my land", "how much money will I make with it" and "how should I do that?". Agrisim is an agricultural decision support system that uses all types and forms of data (public, researched, tested, farmers', own, calculated) with our own algorithms and experiences and visualize it in a cloud-based user interface as a turn-key solution that doesn't need any investments from the user side. Agrisims' optimization process is based on natural conditions like climate and soil characteristics and matches production possibilities of more than 2.500 crops, fruits, vegetables and trees with the parcel. The economic module forecasts yields and prices and calculates the gross-, and net income so the user can compare the margin improvements and the labor intensity attached to it based on sustainable exploitation of the farm. The management support module will tell a farmer what to do when and how every 3 weeks throughout the preparation, growth and harvest period.
