The main aim of this paper is to propose a state of art wireless sensor technology in agriculture, which can show the path to the rural farming community to replace some of the traditional techniques. In this project, the sensor motes have several external sensors namely leaf wetness, soil moisture, soil pH, atmospheric pressure sensors attached to it. Based on the value of soil moisture sensor...

The problem. We study a new geometric optimization problem which arises in carrot crop management [10], as well as wireless network design and various other facililty location problems. The task is to select a number of locations t j for the sprinklers, and assign a radius r j to each sprinkler. A carrot pi is covered iff it is within range of some transmission point t ji , i.e., d(t ji , pi) ≤...

Fire phenomena are complex and involve non-linear interactions between environmental and fire parameters. Computer based methods (Field model and Zone models), by use of numerical methods applyied on mathematical models in the form of differential equations have been widely used for predicting the results of fire phenomena. In the present work an Artificial neural network (ANN) model has been u...

Three test-plot series have been performed to gather information on runoff of sulfonamides from manured arable and grassland after sprinkler irrigation. To prepare test slurries with defined aged residues, liquid bovine manure was fortified with sulfadiazine, sulfadimidine, and sulfamethoxazole and stored short-term. After test-slurry application, the arable land was treated by soil cultivation...

We present here the design and fabrication of a self-powered and autonomous fringing field capacitive sensor to measure soil water content. The sensor is manufactured using a conventional printed circuit board and includes a porous ceramic. To read the sensor, we use a circuit that includes a 10 kHz triangle wave generator, an AC amplifier, a precision rectifier and a microcontroller. In terms ...

The lack of water resources in Iran has increased concern about water consumption in the country. The agricultural sector is known as the largest sector of water consumption, and saving in this sector will save significant water resources. One of the solutions for the optimal use of water resources is the use of modern irrigation methods with proper design and implementation. Therefore, the pur...
