Agricultural practices can result in differences in organic matter (OM) and agricultural chemical inputs in adjacent ditches, but its indirect effects on OM composition and its inherent consequences for ecosystem functioning remain uncertain. This study determined the effect of agricultural practices (dairy farm grasslands and hyacinth bulb fields) on OM degradation by microorganisms and invert...

The toxicities of 10 insecticides were examined against late third instar Culex tritaeniorhynchus Giles (Diptera: Culicidae) using the direct-contact mortality bioassay. Six geospatially-distant field mosquitoes were collected from Chuncheon-si, Hwaseong, Seosan. Jeonju, Daegu, and Busan in the Republic of Korea. Marked regional variations of insecticide susceptibility were observed. Field popu...

An automatic steering controller was installed on a Case-IH Model 7220 tractor. The primary posture sensor was a kinematic differential GPS. Open loop and closed loop frequency response tests were conducted to evaluate the steering controller dynamics. A double integrator transfer function adequately related vehicle lateral deviation to steering angle within the frequency range of 0.04 Hz to 0....

The sweetpotato whitefly Bemisia tabaci Q species is a recent invader and important pest of agricultural crops in China. This research tested the hypothesis that the Q populations that establish in agricultural fields in northern China each year are derived from multiple secondary introductions and/or local populations that overwinter in greenhouses (the pest cannot survive winters in the field...

With more and more importance of correctly selecting partners in supply chain of agricultural enterprises, a large number of partner evaluation techniques are widely used in the field of agricultural science research. This study established a partner selection model to optimize the issue of agricultural supply chain partner selection. Firstly, it constructed a comprehensive evaluation index sys...

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 ...

We present the initial setup of the Lofar Agro project that concentrates on monitoring micro-climates in a crop field. In addition to the agronomic experiment, Lofar Agro aims at gathering statistics on the wireless sensor network itself. These statistics will form the basis for simulations of algorithms in wireless sensor networks and will be distributed. 1. PRECISION AGRICULTURE In the past f...

Typical WSN(Wireless Sensor Network) applications in precision agriculture include production process management, plant growth optimization, farmland monitoring and so on. Middleware, which can connect hardware, applications, and enterprise systems, is required to construct ubiquitous agricultural environment combining WSN technology with different agricultural applications, but there have been...

Agricultural Image Processing is one of the core application of Image processing is one of the most growing research area that is having its participation in different application areas including the biometric system, biomedical system, etc. One of such application area is the agricultural industry. In this application area, image processing is been utilizing in different ways to identify the c...

Accurate spatial information of agricultural fields is important for providing actionable to farmers, managers, and policymakers. On the other hand, automated detection field boundaries a challenging task due their small size, irregular shape use mixed-cropping systems making vaguely defined. In this paper, we propose strategy boundary based on fully convolutional network architecture called Re...
