Abstract:

The population growth associated with natural resources shortage, food demand increasing and the lack of manpower for agricultural activities generate important challenges to agriculture and engineering. The challenges imply the improvement of productivity with fewer resources, This scenario is consisted parameters that generally are in opposite directions.

Abstract:

The World Bank has estimated that an additional $80 billion in financing are needed annually to achieve the 70 % increase in food supply required to feed the world in 2050. One of the cornerstones in achieving this increase in production is expected to be improved agricultural technology, where one of the latest additions is precision agriculture. It is believed that the money for investing in this technology must come from the private sector, but financial institutions are hesitant in lending money to farmers. This, in part, comes down to a high perceived riskiness in agricultural lending ste

Abstract:

Precision Agriculture (PA) is an emerging technology which enables efficient irrigation by employing the Internet of Things (IoT). We split the thesis in two parts. The first part is estimation of humidity level via experimentation. We focus on measuring Received Signal Strength Indicator (RSSI) to obtain humidity level of the field. Thus, we aim at eliminating the humidity sensors which are very expensive and estimate soil moisture through the variation of RSSI values measured by wireless devices buried underground. In the second part of the thesis, we aim at building an accurate and reliabl

Abstract:

Protection management with the aid of plant protection products makes it possible to carry out pest control programs in agricultural environments and make them less hazardous for the cultivation of products on a large scale. However, when these programs are put into effect, only a small proportion of the sprayed products is really deposited on the target area while much of it is carried to neighboring regions. The scientific literature includes studies on the use of mathematical techniques to calculate the physical transformation and movement and provide a deposition estimate of the product. O

This thesis examines the economic and environmental impacts that precision agriculture technologies (PATs) can have on the carbon footprint of a grain farm.

It was found that all three PATs investigated showed a potential Pareto improvement over conventional farming.

Precision agriculture (PA) can be defined as a set of technologies that have helped propel agriculture into the computerized information-based world, and is designed to help farmers get greater control over the management of farm operations. Because of its potential to spatially reduce yield variability within the field through variable rate application of nutrients it is thought to be a production risk management instrument. Subsurface drip irrigation (SDI) is another production risk management technology that is generating interest from the farming community as a result of new technological

Abstract:

Precision farming integrates satellite coordination and information communication technologies into farming practices to deliver self-driving and auto-regulating machinery and equipment to farmers, who can afford to invest, right across the globe. It is often sold on the basis that it can help clean up or ‘ecologically modernise’ conventional, industrial agriculture. It should also increase production rates in industrial agriculture to help to ‘feed the world’ as well as being cost effective in ways that could make farmers more money – miracle-grow formula and win-win technology. There are cri

Abstract:

Alors que les applications d'agriculture de préecision (AP) sont déjà bien établies pour les quadrirotors, la navigation autonome, en particulier dans les champs agricoles complexes, non structurés et capricieux, reste un défi permanent pour ces véhicules. Les stratégies de navigation aérienne autonome ne doivent pas se limiter à garantir que la cible est atteinte sans entrer en collision avec les obstacles. Elles doivent également viser à identifier le chemin et la trajectoire optimaux (ou sous-optimaux) que le quadrirotor doit utiliser pour déplacer de son point de départ à sa destination, e

Abstract:

Soil analysis is one of main resources for obtaining agriculture with quality and gains, being even the first way in planning this activity, to determine the necessity and quantity of fertilizer that each land needs, according recommendation of fertilization and setting. Therefore, this research is the main objective to evaluate the difference between soil analysis in conventional agriculture and soil analysis in precision agriculture. The research was developed in Restinga Seca, RS, at two distinct properties, was developed the system of conventional agriculture and, the precision agriculture

Abstract:

Current trends in agricultural equipment have led to an increasing degree of autonomy. As the state of the art progresses towards fully autonomous vehicles, it is important to consider assumptions implicit in the design of these vehicles. Current automation in harvesters have led to increased sensing and automation on current combines, but no published research examines the effect of machine size on the viability of the autonomous system. The question this thesis examines is: if a human is no longer required to operate an individual harvester, is it possible to build smaller equipment that is

Mestrado Bolonha em Econometria Aplicada e Previsão<br>Nowadays, maize is the most important cereal in the world and its production has been increasing both worldwide and in Portugal, over the years. The constant technological development has led to the creation of new techniques such as precision agriculture, to better meet the global needs of this primordial cereal as well as optimize its production. This research was developed jointly with the firm Agro Analítica from the agriculture sector, whose area of expertise is Precision Agriculture and System Optimization. In this manner, the presen

Abstract:

There is a growing interest in employing sub-soil sensing systems to support precision agriculture. This thesis presents the design of an RFID sub-soil sensing system which is based on integrating passive RFID technology and sub-soil sensing technology. The proposed RFID sub-soil system comprises of an above-ground RFID reader and a number of RFID sub-soil sensor nodes. The key feature of the system is that the sensor nodes do not require an on-board battery, as they are capable of harvesting energy from the ElectroMagnetic (EM) field generated by the RFID reader. The sensor nodes then transmi
