What is a Granular Matrix Sensor?
Granular matrix sensors (GMS) represents an option for measuring soil water to schedule irrigation. Irrigation of crops highly sensitive to water stress, like potatoes, onions, and many other horticultural crops require precision irrigation scheduling, determining both irrigation frequency and duration.

Secrets Hidden In Soil
Soil means different things to different people. Earth scientists see soil as mineral or organic material that is formed on Earth's surface by dynamic, complex processes. Agriculturalists think of soil as the top 15-30 cm of Earth's surface to grow crops, while others think of soil as dirt which one plays in or gets "dirty" from.

How to Install a Drip Irrigation System?
Low-flow irrigation is gaining ground in landscapes all over the country. Today, many residential and commercial landscapes require more low-flow zones than standard turf zones. It's important for contractors to keep current about the latest drip and micro-spray technology and how to install it.

Crop Coefficients (kc) for : Grapes
By Department of Rural Engineering and Natural Resource Protection
The kc values for grapes will vary considerably with cultural practices such as vine and row spacing, pruning, trellising height and span, and with extreme varietal differences in vine growth. Grapes, normally clean cultivated, use less water than many other crops due to cultural practices resulting in only 30 to 50 percent ground cover. Also there may be a somewhat greater degree of stomatal control of transpiration compared to many other crops.

Causes and Prevention of Emitter Plugging In Microirrigation Systems
Emitter plugging can result from physical (grit), biological (bacteria and algae), or chemical (scale) causes. Frequently, plugging is caused by a combination of more than one of these factors.

Media Filters For Trickle Irrigation In Florida
Trickle emitters use small orifices or long flow paths with small diameters to deliver the small flow rates required. Thus, they are subject to clogging by particulate matter, organic growth, or chemical precipitate from the irrigation water. Effective and reliable filtration is mandatory for successful trickle irrigation operation.

Treating Irrigation Systems with Chlorine
Chlorine is used in many water supply systems and home swimming pools to prevent algae and other microorganisms from growing. Chlorine is also used for cleaning and maintaining irrigation systems.

Drip irrigation, also called trickle irrigation, bubblers and localized small microsprinklers, microspinners and microsprayers are collectively referred to as microirrigation.
An Introduction To Drip Irrigation
Malheur Experiment Station - Oregon State University
Drip irrigation can be a great aid to the efficient use of water. A well designed drip irrigation system or subsurface drip irrigation system will lose practically no water to runoff, deep percolation or evaporation. Irrigation scheduling can be precisely managed to meet crop demands, holding the promise of increased crop yields and quality.
Screen Filters in Trickle Irrigation Systems
Water quality is a major concern in the management of trickle irrigation systems. Emitters plugged by physical, chemical, or biological contaminants may create significant problems in everyday maintenance. Therefore, effective and reliable filtration is mandatory for successful operation of trickle irrigation systems.
There are different types of filters available for the removal of physical contaminants from irrigation water. Selection of a filter depends on the type and amount of contaminants in the irrigation water, as well as the size of the irrigation system and the desired management practices. Various types of screen filters are commonly used in irrigation systems.

Using Plastic Mulches and Drip Irrigation for Vegetable Production
Muskmelons, tomatoes, peppers, cucumbers, squash, eggplant, watermelons and okra are vegetable crops that have shown significant increases in earliness, yield, and fruit quality when grown on plastic mulch.

Vegetable Crop Irrigation
Vegetables are 80 to 95 percent water. Because they contain so much water, their yield and quality suffer very quickly from drought.

MICRO-IRRIGATION
The Future of Water Conservation
By Sam Tobey - president of Salco Products, Inc.
Whenever there is a constantly increasing demand for a finite resource, two things can happen; the price of the resource goes up or government intervention comes into play. In today's socio-economic environment, both of these are happening in certain parts of the world, in regard to irrigation.
