Ferramenta para cálculo de balanceamento de macronutrientes do solo

Abstract

The intensive livestock production generates as byproduct large amounts of manures. One of the options available for using wastes of animals is the application as a complement in the soil fertilization due to the fact that these residuals have considerable levels of nutrients for example N, P and K (nytrogen, phosphorus and potassium). The application should occur in a controlled way in order to avoid soil contamination or environmental impacts such as soil and rivers contamination. This work has as its main purpose develop an app that will recommend the ideal amount of organic waste which will be applied on soil.The calculation will be made from the concentration of nutirents on the manure, rate of efficency, soil analysis and the fertilization’s recommendation for cultivation used.The user will have as a result the ideal quantity of manures used for hectare and the supplementing in which minerals fertilizants should be used.In addition to this, the app will allow the user to change the manures recommended quantity according to what is available. For this, it was used framework Ionic, which uses web html, css and Javascript technology.
