| Global Positioning System (GPS) is a global navigation satellite system that provides geo-location and time information to a GPS receiver anywhere on or near the Earth. Machine operation track, turning pattern, effective time of field operation, field capacity, field efficiency, machine idle time, etc. can be evaluated precisely by using geo-referenced data recorded by a GPS receiver during field operations. Highly precise GPS receivers are expensive and unaffordable for farmers and farm operators in Bangladesh. Keeping this in mind the scope of an affordable and easy to handle GPS receiver was explored in the study. A GPS receiver was used to record the data generated by combine harvester and mini combine harvester during harvesting. Data were recorded... |

| Com o crescimento da mecanização da cana-de-açúcar, é necessária uma dinamização dos processos, como no uso de técnicas de agricultura de precisão para uma diminuição do custo de produção. O presente trabalho foi desenvolvido com o objetivo de contrastar a acurácia nas passadas orientadas por dois sistemas de direcionamento, autodirecionamento via satélite versus manual, assim como comparar as capacidades de campo e a eficiência operacional envolvidos no plantio mecanizado da cana-de-açúcar. Foram analisados dois tratamentos: com e sem o auxílio do piloto automático por GPS RTK na operação de plantio mecanizado. As avaliações foram realizadas em condições de campo, na Usina IACO Agrícola S.A., em Chapadão do Sul - MS. De acordo com os resultados obtidos,... |

| We used miniaturized GPS loggers and site observations to access foraging patterns and nest behaviour of the White-tailed Tropicbird Phaethon lepturus (WTTB), an endangered species at its South Atlantic breeding colony. Dual foraging pattern was observed with alternation between long and short foraging trips. Birds responsible for nest attendance engaged in short foraging trips with mean distance from colony of 25 +/- 17 km, total distance covered of 79 +/- 65 km and mean duration of 4.02 +/- 5.28 hours. Birds flew by dawn and returned before dusk while partners were at sea for long foraging trips that ranged from four to 11 days, with mean maximum distance from colony of 105 +/- 47.48 km. Chicks were usually left alone for hours and chick predation by... |

| Foi desenvolvido um conjunto de equipamentos com o objetivo de mapear as áreas infestadas por macrófitas aquáticas, auxiliando operações de manejo mecânico, as quais são realizadas por uma colhedora desenvolvida especificamente para essa finalidade. O conjunto de equipamentos foi constituído por um GPS com programa de correção diferencial, acoplado a um palmtop, um sistema com dois teclados ligados em dataloggers e um transdutor de deslocamento linear LT. O GPS, através do palmtop, proporcionava o mapeamento da área de deslocamento, auxiliando o operador na movimentação da máquina, otimizando a operação e evitando, dessa forma, a sobreposição das faixas de coleta na área a ser manejada. Um dos teclados monitorava a movimentação e operação da colhedora,... |

| ABSTRACT The mechanical resistance to penetration when related to the water content is an indicator often used of soil compaction, the use of positioning methods for greater accuracy of this review is important. In this context, this study aimed to determine the variability of positioning methods provided by GPS receivers to determine the spatial behavior of physical attributes related to soil compaction. The study area is located in the municipality of Jaboticabal, around the latitude 21º15’22”S and longitude 48º18’58”W, being characterized with a clayey Oxisol. The variables used as parameters of soil physical properties were the mechanical resistance to penetration and water content, using a sampling grid of 20 x 20 m, totaling 60 points. We used six... |

| Soil electrical conductivity (EC) is a measurement that links with the soil properties that will affect crop productivity. With advances in technology for precision agriculture, Veris Technologies introduce the on-the-go sensors for measuring level of Soil EC. The combination of sensor with EC help in improving our farming system. This study was conducted at Share Farm UiTM Jasin,Melaka in Young Oil Palm area and used to measure the level of EC. This implement (Veris 3100) connected along with Auto Pilot Tractor (New Holland TD575). It works together with GPS to get accurate location before it converted to map form. The collected data contain shallow and deep. Each data shows different amount of EC. Shallow measure from 0-30cm while Deep from 0-90cm and... |
