In this research, the model of SWCT (soil water content and temperature) was developed for simulation of fluxes of soil water (liquid water and water vapor) and heat. The governing equations for water and heat fluxes were solved using numerical finite difference method. Soil water content and...

We examine the water-use balance, fruit yield and water-use efficiency of five-year-old peach trees with two different mulching systems: plastic film mulched ridge, with furrows (PFM) and straw mulched (SM). Compared with the clean tillage (CT) water management method, PFM increased, and SM...

Soil mulching material significantly affects the energy balance and soil thermal regime. In order to study the effect of soil mulching with a paraffin-wax emulsion on soil thermal regime, we developed a one-dimensional numerical model, which simulates the microclimate of the mulched soil. The...

Advancement in genetic algorithm (GA) optimization tools for design applications, coupled with techniques of soft computing, have led to new possibilities in the way computers interact with the optimization process. In this paper, the concept of goal-oriented GA has been used to design a tool...

The spatial variability of surface temperature has been examined under greenhouse conditions at Al-Mada'in Research station. Soil temperatures were measured at 14:00 h on 3 consecutive days after a trickle irrigation. Measurements were made every 0.5 m along a 55-m transect with...

An agricultural greenhouse with natural ventilation in Thailand has to deal with high temperature. This problem shows the necessity of having a tool capable of predicting soil temperature and moisture in the greenhouse using the statistical data from the meteorological station. Rice husks were...

In this article, we use the concept of artificial neural network and goal oriented design to propose a computer design tool that can help the designer to evaluate any aspect of earth-to-air heat exchanger and behavior of the final configuration. The present study focuses mostly on those aspects...

Ground Source Heat Pumps (GSHPs) are extensively used as renewable energy technology over the world. In heating-dominated buildings, the ground thermal imbalance leads to the decrease of the soil temperature and deteriorates the heating performance. Compared with Ground Source Electrical Heat...
