In Colombia, innovation is an aspect of fundamental importance to increase the country’s productivity and so it is imperative to promote new ideas, particularly in agriculture sector, where technological developments may lead to the implementation of modern techniques within the production cycle of crops (replacing more traditional, less efficient processes). In this regard, the use of ICT (Information and Communication Technology) and, more specifically, the introduction of IoT (Internet of Things) as a supporting element of the so called Precision Agriculture (PA) is crucial to ensure productivity in crop fields. The present paper shows evidence of a significant productivity increase, based on growth control, achieved by using technological tools that reduce weed volumes around target crops. A set of good practices carried out in specific areas of the world is reported so as to provide an overview of the existing techniques intended to control weeds in different types of fields and under different climate conditions. Subsequently, the paper discusses a survey of the current technological developments in the agricultural sector in Colombia. The discussion ultimately outlines the proper conditions to promote the development of technology-based projects that offer efficient solutions and contribute to the welfare of a specific target population, namely the peasant farmers of Colombia.
