PROJETO DE IRRIGAÇÃO VIA ASPERSÃO CONVENCIONAL COM AUXÍLIO DE AEROFOTOGRAMETRIA PARA CULTURA DO MILHO

Abstract

Irrigation is an agricultural practice that allows achieving the ideal water requirements of crops during the production cycle when natural precipitation is insufficient. The use of this method improves the efficiency of water application in the soil, enabling greater root development of the plant. By combining agricultural practices with technologies, agriculture becomes precise, modernizing, automating, increasing productivity, and enabling greater efficiency in the use of natural resources. Therefore, the objective of this work is to develop a conventional sprinkler irrigation project for corn cultivation, with the aid of aerial photogrammetry in data collection. To achieve this goal, we conducted an aerial survey with a drone, generating an orthomosaic of aerial images and a Digital Terrain Model through processing with the WebODM software. Additionally, a literature review was conducted to obtain technical information related to corn cultivation, soil, and the climate of the region, aiming to dimension the hydraulic and operational aspects of the project. This allowed us to size the head loss, pipe diameters, power demand of the pump unit, as well as costs related to energy expenses and components of the irrigation system. Based on the methods employed and the results obtained, we could conclude that the use of aerial photogrammetric data can save time and human resources without compromising the precision and quality of the final product.
