Agricultural production management is entering into a new era where every day farmer's decisions are supported by highly sophisticated Farm Management Information Systems (FMISs). The latter have evolved from simple record keeping software complex systems that can manipulate large amounts of data and provide decision support capabilities. In this paper, the development an FMIS, which utilizes technologies, such as those were introduced European initiative Future Internet Public-Private...

One of the main targets a greenhouse control system is to generate uniform climate environment, which has obvious economic advantages, due homogenous crop, lesser diseases and potential energy saving. By using dense wireless sensor network, spatial distribution parameters thus uniformity environment can be determined. This information used by growers detect cold wet spots in adjust their system. In this study, horizontal heterogeneity analysed. Six experiments were performed commercial...

The food supply chain is responsible for a large share of the anthropogenic contribution to global warming, as well being major contributor several other impact categories such acidification and eutrophication. Therefore, it necessary find ways limiting from production chain. Many crops are not adapted growing in regions with cold climate, which creates need either import them or use methods greenhouses artificially create good conditions crops. Sweden currently reliant on imports many...

Several greenhouse energy saving technologies and management strategies have been developed in order to meet the needs for implementation of production systems with low efficient use CO2 emissions. Towards this aim, a number concepts that make these tested, such as closed greenhouse, solar energy-producing others. The or semi-closed concept is widely accepted achieve targets A major difference conventional climate control by window ventilation partially completely replaced treat air,...

An experimental greenhouse equipped with fan and pad evaporative cooling is analysed using two different models. The first one consists of a numerical simulation approach applying commercial CFD code. main aspects systems, in terms heat mass transfer both the external internal climatic conditions were integrated to set up model. crop (tomato) was simulated equivalent porous medium by addition momentum energy source term. temperature humidity incoming air, operational characteristics exhaust...

An experimental greenhouse equipped with fan and pad evaporative cooling is simulated numerically using a commercial CFD code. The main aspects of systems, in terms heat mass transfer both the external internal climatic conditions were integrated to set up numerical model. crop (tomato) was equivalent porous medium approach by addition momentum energy source term. Preliminary calculations carried out validated measurements, order pressure drop occurred model due air flow, be determined as...

Concerning the greenhouse environment, ultimate goal of an investigation would be to determine climatic parameters for all locations in study area. Objective present is analyse distribution air temperature and velocity experimental with tomato crop, equipped fan pad evaporative cooling system, using geostatistical methods. The main aspects geostatistics terms theoretical background understanding spatial correlation models kriging applications are presented. most common variogram were fitted...

In Turkey, protected cultivation includes the production in greenhouses and under low plastic tunnels. The total area reached 64 912 ha 2014, of which 76% is greenhouses. As other Mediterranean countries, mainly located where climatic conditions are favourable for without any additional heating. However, last decade high tech have been introduced particularly order to use renewable alternative energy greenhouse this research a climate crop yield model was used evaluate possible improvements...

In the Mediterranean greenhouse areas, a large majority of growers rely on passive techniques to improve microclimate during winter period, rather than using more expensive systems such as active heating. Some these different types mulch (sand, plastic films, etc.) are used heat storage capacity soil. A proper modeling role soil store would allow verification which have larger positive effect (i.e. type, color and thickness mulch, moisture content, how optimize their management by grower....

In livestock buildings the ventilation rate influences both pollutant emission rates and animal?s welfare. present study a 3D simulation model was used to simulate 7 commercial dairy cow houses with different roof types side ventilators. The simulations have been carried out considering wind speeds (1, 4 8 m/s), directions (0, 45 90°) outside air temperatures 10 20°C). resistance of cows flow calculated by simulating virtual tunnel cows. experimental tracer gas method (constant injection...
