Given the global environmental crisis and its association with soil degradation, climate change and water scarcity, there is a need for better decision making processes regarding agricultural land management. This in turn creates the need for systems that are able to manage, process and analyze large amounts of information. The aim of this study was to describe the creation and use of three different softwares.

They were designed and developed using Eclipse as programming interface, Derby as database management system and Java as programming language.

The Soils and Environment (S&E) software uses a few soil properties to perform environmental assessments of soil profiles. These assessments are performed qualitatively, considering Human life, Flora and fauna, Natural Archive and Cultural Archive, and quantitatively, considering Water Cycle (associated with field capacity and hydraulic capacity), Nutrient Cycle (cation exchange capacity), Heavy Metals (pH, CEC, texture and structure), Means of Transformation (organic pollutants), Food and Biomass (field capacity, aeration capacity and effective cation exchange capacity), Filtration and Infiltration, and Organic carbon Stock.

The software for evaluation of water quality for agriculture (Agriwater) was designed to evaluate the quality of irrigation water (salinity, sodicity, chlorine toxicity) and to identify water families. The transformation of units is done automatically.Diapositiva2

The Climate Change with Monthly Data (Clic-MD) software was designed to analyze climate change trends at the local level using monthly data; with Click-MD, we can make up to 432 graphs of indicators of climate change per weather station.Diapositiva1

S&E, Agriwater and Clic-MD facilitate the management of large databases, which in turn improves staff productivity and related data management, and reduces the time of analysis by more than 90%.
