Recent developments in aerospace survey technology, modelling of crop production processes, and geographic information systems have created promising opportunities for agricultural resource management. One of the potential fields of application is in the agricultural risk management, in particular in assessing the impacts of natural hazards on agricultural productions. This seems to be the bott...

The arrival of the era of third-generation (3G) mobile phone will cause earth-shaking changes, as a kind of new communication technologies will play in the fields of estimation. The rapid development of electronic technology and information technology, which had brought about a revolution of control and management of agricultural, mobile 3G era will give the agricultural revolution fueled, and ...

The College of Agricultural Sciences and Natural Resources (CASNR) dates back to 1869 when the university was designated as Tennessee’s federal land-grant institution. Under terms of the Federal Land-Grant Act, the university was enabled for the first time to offer instruction in agriculture. Later, federal legislation provided resources for agricultural research and extension programming for d...

At present the government performance evaluation has already become popular in all fields of government performance management. It contributes a lot to the construction of service-oriented government. However, the quantitative evaluation on government performance is far different from each other in practice. This paper tends to explore the development trend of quantitative evaluation on agricul...

To assess the change in the size of the eastern North American monarch butterfly summer population, studies have used long-term data sets of counts of adult butterflies or eggs per milkweed stem. Despite the observed decline in the monarch population as measured at overwintering sites in Mexico, these studies found no decline in summer counts in the Midwest, the core of the summer breeding rang...

The spatial and temporal stability of soil test values is important to the use of soil testing for nutrient management. A study was conducted to evaluate the spatial and temporal stability of soil test phosphorus (P). Five sites ranging in size fiom 9.1 to 10.8 acres were soil sampled in the same locations in a 60 X 60 ft. grid either three or four times over a two year period. Bray 1 -P values...

Understanding the drivers and consequences of diversity and productivity in plant communities remains a central challenge in ecological research (Thompson et al. 2001, Mittelbach 2012). Interest in how the diversity and composition of plant communities regulate ecological processes and ecosystem services that different ecosystems provide has expanded over the past two decades (Loreau et al. 200...

Working on new equipments to increase agricultural productivity and safety, reducing human action hardness , Cemagref and Lasmea have developed an help guidance system for agricultural vehicles. The aim of this system is to help the operator to guide the machine in order to give more attention to the order task. To reach this goal, we use a visual perception of the environment because this sens...
