Quantification of soil surface evaporation under micro-scale advection in drip-irrigated fields
The objective of this study is to quantify soil surface evaporation under micro-scale advection in drip-irrigated fields. A numerical model for estimating soil surface evaporation under micro-scale advection, assuming drip-irrigated fields, is introduced. Results indicate that the soil surface evaporation changes spatially. Soil surface evaporation at the upwind edge of wet soil portions adjacent ...

Eima 2016: A success for irrigation
Energy saving and maximum efficiency are the cardinal points of agriculture 2.0. Today, through the micro irrigation and subsurface irrigation, agricultural production reached a high level of efficiency that assures quality and quantity. “Micro-irrigation”, or drip irrigation, is a method which allows the farmer to give the same amount of water to the roots of each plant, without ...

Florida - Island Development case study
Steeped in history and tales of pirates, Blacks Island has become a residential paradise, thanks in part to creative decentralized wastewater solutions. In October of 2006, Blacks Island LLC received approval to begin construction of a twenty-six lot residential development on this seven-acre island located off the Florida panhandle in St. Joe Bay. The town of Port St. Joe sprang up in the ...

Kentucky - Golf Homes Development case study
Site: County Club Golf Homes Location: Elizabethtown Kentucky The Country Club Golf Homes (CCGH) located in Elizabethtown, Kentucky is a shining example of how technology, engineering, and land development can come together to make unsuitable land suitable for onsite wastewater dispersal. In late 2001, the CCGH developers required assistance with their patio home construction project. ...

Crops flourish with Scalewatcher
Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit. Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated greenhouses, ...

Can drip irrigation keep the Prairie Profitable?
The use of flood and center pivot irrigation of crops via the waters of the Ogallala Aquifer is as hot a discussion topic as the current drought. To many who mine the aquifer to make a living, trying to keep a profitable way of life sustainable in a time when the broader public is seeking more conservation of resources yet wanting inexpensive, plentiful and safe food is problematic. Perhaps it's ...

Greenhouse Tomatoes - Organic farms use smart data for optimum yield - Case Study
A greenhouse organic tomato and cucumber grower saved his crop during extreme drought with Sensoterra sensors, and improved yield with soil moisture data. With extreme droughts occuring more frequently, Danny Monté, Forecast and Quality Administration and Quality Control Manager at AC Hartman BV, relies on Sensoterra soil moisture sensors to support irrigation decisions for greenhouse ...

Reuse of Dairy Lagoon Wastewater Through SDI in Forage Crops
Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of Subsurface Drip ...

Microbial risk in wastewater irrigated lettuce: comparing Escherichia coli contamination from an experimental site with a laboratory approach
This study assessed the contamination of Escherichia coli, in lettuce grown with treated domestic wastewater in four different irrigation configurations: open spray, spray under plastic sheet cover, open drip and drip under plastic sheet cover. Samples of lettuce from each irrigation configuration and irrigating wastewater were collected during the growing season. No E. coli was detected in ...

Digging deep for new irrigation methods
Irrigation is essential to increase food production. However, competing needs and increasing drought makes water for irrigation scarce. Therefore, new methods and strategies are continuously being tested by scientists to improve food production, accompanied by better water use efficiency. This article will examine how modern field tools are helping in this venture. Irrigation Methods According ...

Why Drip Irrigation Design is Crucial to Your Success
Drip irrigation is one of the most cost-effective and efficient watering methods in agriculture. It has become incredibly popular in the past 50-years and has been widely adopted by agriculturalists in dozens of countries throughout the world. In simple term, drip irrigation works by sending water through plastic pipes into drip emitters. These emitters are specifically designed to release water ...

Soil Moisture Terminology
Soil Moisture Terms. What do they mean and how do we use them? By the end of this short article you will hopefully understand the following statement. “For good crop growth, maintaining water above stress point will maximise vegetative growth. Setting a refill point above stress point will ensure there is always readily available water for the crop. Replacing ...

How to grow more food with less water
Scientists and farmers collaborate on a quest for more efficient irrigation This story was co-published with Civil Eats, a daily news source for critical thought about the American food system. From reading the weather to choosing a crop, farming has always been a hands-on enterprise. When a farmer wonders how much water a crop needs, a simple test has always sufficed: Grab a handful of soil ...

With Tomatoes, Less Is More
As you round the final bend of Road 95 through the groves of walnut and almond trees, it would be easy to miss Muller Ranch, but for the cluster of pickup trucks circling the driveway. Yet amidst these swaying Yolo County orchards sits a stunning third-generation, family-owned farm, thriving with several thousand acres of processing tomatoes, specialty peppers, corn, wheat, canola, cucumbers, ...

Water reuse through subsurface drip irrigation systems
Water reuse in Hawaii has been primarily relegated to agricultural irrigation and irrigation of golf courses and other large landscaped areas. The continuing effort to conserve and preserve potable water resources emphasizes using alternative water sources for irrigation. Agriculture, golf courses, highways, parks, playgrounds and cemeteries are among the heaviest users of irrigation water due to ...

Expanding the applications of micro irrigation `Drip` treatment and disposal systems in Delaware
Abstract An 18–month field evaluation of four micro–irrigation "drip" treatment and disposal systems was conducted to determine if reducing the separation distance between the bottom of the drip–line and the seasonal high water table (limiting condition) could be reduced from 18 inches to 12 inches. In this study three systems did not have advanced treatment while the remaining ...
