Commercial greenhouse water demand sensitivity analysis: single crop case study
Today water distribution utilities are trying to improve operational efficiency through increased demand intelligence from their largest customers. Moving to prognostic operations allows utilities to optimally schedule and scale resources to meet demand more reliably and economically. Commercial greenhouses are large water consumers. In order to produce effective forecasting models for ...

10 Easy Tips To Build and Design A Small Greenhouse Watering System
Building Your Own Mini-Greenhouse Can Be A Fun And Educational Experience, As Well As A Rewarding One. Especially If You’re Good With Tools. If You Are Using A Greenhouse To Initiate Transplants Or Grow Plants To Maturity, The Greenhouse Should Be Located In An Area That Will Receive The Most Sunlight. It Should Also Be Located In A Well-Ventilated Area. Avoid Building Greenhouses In ...

Phytoextraction of Phosphorus-enriched grassland soils
Received for publication February 7, 2008. High soil P contents in agricultural soils in the Netherlands cause excessive losses of P to surface waters. The reductions in P application rates in the present manure policy are not sufficient to reach surface water quality standards resulting from the European Water Framework Directive in 2015. Accordingly, additional measures are necessary to reduce ...

Performance evaluation of condensation–irrigation solar system under arid climate conditions
Scarcity of water, major critical concern in arid areas, has led to the use of low–quality irrigation water in agriculture in most of arid climate areas. The quality of water used for agriculture has to be reduced to a sustainable level that is also adapted to the environment. This paper presents the performance of a pilot condensation irrigation (CI) solar system in Tunisia under arid ...

Measurement and modelling of the water requirement of some greenhouse crops with artificial neural networks and genetic algorithm
Crop evapotranspiration is the most important parameter for management of irrigation systems in greenhouses. This study was conducted to determine the evapotranspiration of cucumber, tomato and peppers, using micro–lysimeter during seven months in a greenhouse located in central region of Iran. Reference evapotranspiration estimated using drainage lysimeters and the water balance of soil ...

Pesticide runoff from greenhouse production
A research has been undertaken studying pesticide residues in water from greenhouses and the use of soils and filter materials to reduce such losses. The pesticides detected in water samples collected downstream greenhouses include 9 fungicides, 5 herbicides and 4 insecticides. 10 compounds from flower and vegetable productions were frequently found to exceed environmental risk levels, and with a ...

On site at Northdown Orchard Organic Farm
On Saturday 15th of October we were on site with Mike and the team at Northdown Orchard, an existing customer who was kind enough to show us around the farm and let us snap some great photos at his site in exchange for a morning demonstrating our latest stone burier on his tractor. About Northdown Orchard The organic farm is a family run affair and sits on a site of 12 acres. Mike and his ever ...

Re-evaluating the rationale for irrigation technology adoption through an integrated trade-off analysis: case study of a cotton farming system in Australia
While the prevailing rationale for new irrigation technology adoption is improved water use efficiency, this study evaluated trade-offs between water savings, greenhouse gas (GHG) emissions and economic gain associated with the conversion of a furrow irrigation system to a sprinkler irrigation (lateral-move) system on a cotton farm in eastern Australia. Trade-offs were evident when conversion ...

Environmental input–output analysis of the New Zealand dairy industry
This work presents data and analysis quantifying the total (direct and indirect) resource use and outputs (products and pollutants) of the New Zealand dairy industry for the year April 1997 to March 1998. It also identifies those sectors supplying the dairy industry which make significant indirect contributions to its total inputs and outputs. Although this data is 14 years old, it is the only ...

Aiming to optimize irrigation levels
With irrigation being used in many spheres of life and food production methods getting diversified, it is not surprising that research on this topic is getting more specialized. Procedures for analysis, which were restricted earlier to big institutions, need to be widely available so that their reach is extended and science will benefit from more in-depth studies. An increasing number of ...

Irrigating with saline or seawater
Currently, agriculture uses seventy percent of the freshwaters, globally. Available freshwater sources will not be enough to increase food production to feed growing populations in the coming decades. Therefore, there is a concerted effort to grow crops with seawater. Hence, scientists are investigating the various challenges involved in growing plants with saline water. These include greenhouse ...

Modelling water requirements of greenhouse spinach for irrigation management purposes
Estimating water requirements of plants cultivated in greenhouse environments is crucial, both for the design of greenhouse irrigation systems and the improvement of irrigation scheduling. Spinach is one of the main vegetables sold as ‘ready-to-eat’ bagged produce; it is very sensitive to water stress and thus requires accurate irrigation. In this work, a water balance model simulating the ...

Differential effects of low humidity levels on butterhead quality indices related to external, middle and internal lettuce sections
Leaf water status evolution during greenhouse butterhead lettuce storage under adverse humidity conditions was evaluated. The relationships between water status and the chlorophyll content and overall visual quality (OVQ) were analysed. Parameters were evaluated in external, middle and internal sections of the lettuce heads. Indices showed different behaviour in different sections. There was a ...

New Mexico Business Weekly Passing biogas: R-Qubed project converts cow manure to methane
Some locals sarcastically joke that the stretch of dairy farms along Interstate 10 south of Las Cruces should be re-named “Buenos Aires” (fresh air). It’s a reference to a less than aromatic sector of I-10 in southern New Mexico, not a reflection on the capital of Argentina. But that soon might change, thanks to a US$72 million plan by R-Qubed Energy Inc. of El Paso to build ...

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, ...
