Software para recomendação de calagem e adubação do tomateiro no estado de Minas Gerais

Abstract

Informatics can be helpful in the search of increased effectiveness and professionalism in tomato cultivation. The State of Minas Gerais is a major producer in Brazil. The purpose of this paper was to develop a software for use via internet with a friendly interface and intuitive navigation, to be employed as a tool for recommending liming and fertilization to tomato cultivation based on fertilization tables of the Comissão de Fertilidade do Solo do Estado de Minas Gerais CFSEMGE 5th approximation. The work was conducted in the facilities of the Instituto Federal do Sul de Minas, Machado campus, MG, and the José do Rosário Vellano University, Alfenas campus, MG. Two technologies were used for the development of the software: JAVA (programming language) and MYSQL (database). Among its features, the software performs the registration of producer, property, cultivated area, and data from soil analysis. Its main function is to calculate the amount of lime and fertilizer using macronutrients (nitrogen, phosphorus and potassium) and micronutrients (boron and zinc). The easy-to-use compound obtained does not demand the installation of computers and high settings, what allows the generation of reports containing information about all the entries made, and the recommendation of liming and fertilization for the use of agronomists, technicians and producers.
