Description
Excelic Press Trickle Irrigation by Hédi Ben Ali
Agricultural irrigation is highly important in crop production everywhere in the world. Water scarcity is among the main problems to be faced by many societies and the world in the 21st century. Therefore, efficient water management plays an important role in the irrigated agricultural cropping systems. Trickle irrigation or drip irrigation is a localized irrigation method that slowly and frequently provides water directly to the plant root zone. Drip irrigation system is widely spread as it can be used safely for most soil types; beside it has high theoretical application efficiency. The use of drip irrigation has been increase in most crop commodities, especially vegetable and fruit crops, to improve water use efficiency and water supply. Nowadays, however uniform is the distribution of water onto land surface is accepted collectively of the key criteria for evaluating irrigation system performance. Poor irrigation-water-application uniformity will be an explanation for low crop-yields. Improved yields might result from maintaining the soil wetness at AN optimum level through additional frequent water and nutrient application. This may result from a Homogeneous water application and effective planning.
This book brings state of the art current knowledge from different engineering and scientific disciplines desirable for understanding the trickle irrigation system for crop production. The book also focuses on the factors that can affect the flow variation of emitters in the drip irrigation system of steep slope land, such as: initial filling of pipe, drainage water from the pipe after stopping irrigation and pressure variation. The book takes a critical look on effect of soil properties on hydraulic characteristics under subsurface drip irrigation and intelligent irrigation performance in arid regions. Traditional instrumentation supported distinct and wired solutions, presents several difficulties on measurement and management systems particularly over the massive geographical areas. Therefore, Associate in Nursing automation technology and its equipment like drip irrigation, sensors and device is provided for the best usage of water resources in agricultural areas. The book follows with water productivity and fruit quality in deficit drip irrigated citrus orchards and the effect of irrigation method and non-uniformity of irrigation on potato performance and quality. The book closes with a study on insectigation in vegetable crops as, today, many agricultural chemicals are labeled for application through various irrigation systems, including overhead, sprinkler, and drip/trickle, in vegetable and other crops. This book will appeal to students, designers, manufacturers, agronomists, horticulturists, and users of drip irrigation systems.
