Various processes are carried out in the Soil and Fertilizer Department of the Ministry of Agriculture at Granma's province in Cuba, including information management for investment approval. It becomes difficult due to the fact that it is carried out manually and through printed models, leading to insufficiencies in the personnel in charge of recording the information, difficulty in preserving relevant information and delay in the response process. In response to these needs, in this investigation, an informatics system is developed that will enrich the management of the information for the approval of investments of Soils and Fertilizers in Granma. For the development of the system was utilized as methodology of development of software Extreme Programming (XP). PHP 7.3.3 and SQL as server-side, client-side programming languages HTML 5, CSS 3, JavaScript and JQuery 1.2.2. APACHE 2.4.38 web application server, MySQL 5.0.12 as Database manager, CodeIgniter 3.1.10 as Framework and DBDesigner 4 as an aid to database modeling. As a result of investigation, a system validated by means of proofs of software was obtained, which vouch for his correct functioning.
