17. Conceitos e considerações práticas do sistema de geração de mapas de produtividade na cultura de grãos.
ABSTRACT: Precison Agriculture adoption is increasing on savannas region in the central plain areas in Brazil, principally because fertilizers and others pesticides were saved reducing the cost of grain production in the agricultural areas. But environmental pollution with these products area also become a problem. It was estimated that the are with variable

18. Comparação de modelos receptores GPS para utilização na agricultura de precisão.
ABSTRACT: After the liberation of Selective Availability (S/A) several GPS receivers started to have enough accuracy or precision for work with grid sampling in Precision Agriculture. There are few articles describing the accuracy and precision of these receivers. The objective of this work was compared and calculated the accuracy of two models very used for

19. Aplicação localizada de herbicidas.
ABSTRACT: Curent interest in site-specific weed control considering the weed spatial variability is increasing nowadays, when economical and environmental aspects are considered. This paper reviews the patch spraying methods for herbicides application systems regarding the economical and technical aspects. Using this new approach high herbicides savings are

20. Geração de mapas de produtividade para experimentos com milho no âmbito de fazenda.
ABSTRACT: Many farmers do not use precision agriculture tools due to high equipment costs and lack of knowledge about this new approach. A number of farmers have, however, conducted on-farm experiments without the help of these new and still expensive tools. One of most important equipments for precision agriculture practices is the crop yield monitor. It ca

21. Manual de utilização das principais funções do programa computacional ArcView 3.2 no apoio à agricultura de precisão.
ABSTRACT: As the Precision Agriculture (PA) concepts consider that the agricultural fields are heterogeneous and need to be managed accouting for spatial variability, the soil fertility, crop yield and pest maps have to be generated by using specific softwares for data gathering and analysis. In this type of data, the geographical positions are crucial. Nowa

22. Tecnologia de aplicação de herbicidas.
ABSTRACT- Pesticide applied incorrectly may result in wasted products, poor or no control, damage to crops or environmental contamination. The aim of this publication was to organize in one publication several technical information found in the scientific literature of herbicide application technology. This approach will help farm growers, students and techn

23. Procedimento para estimativa da intensidade de precipitação máxima admissível em pivô-central com base nas características do equipamento e do solo.
ABSTRACT: A procedure to estimate the center pivot maximum application rate, based on equipment and soil characteristic is presented. It was developed to minimize the surface runoff. To achieve this objective, the Green and Ampt (GA) infiltration equation was modified to include surface sealing and surface storage. The highest application rate is determined

24. Mapeamento da variabilidade espacial das plantas daninhas.
Traditionally the weed management has been done considering the overall weed infestation in the whole field and then herbicides are sprayed according to a single weed control recommendation for the field. But weeds are not uniformly distributed and normally have clumped populations showing weed patches presenting high spatial variability. This nature of the
