Can Conservation Incentives Actually Increase Water Use?

Frank A. Ward (Department of Agricultural Economics and Agricultural Business, New Mexico State University) and Manuel Pulido-Velazquez (Department of Hydraulic and Environmental Engineering–Institute of Water and Environmental Engineering, Universidad Polite´ cnica de Valencia) recently published a scholarly article which suggests that water conservation subsidies will not provide farmers with economic incentives to reduce water depletion.  A focus of the study was drip irrigation.  While its benefits were discussed, the research suggests drip irrigation does not necessarily save water when considered from a basin scale.  The entire scholarly article can be read at:

Net Irrigate commends Ward and Pulido-Velazquez for their research efforts.  In addition to the insightful content, one particular paragraph of their report struck a cord with us:

“What measures can be taken to promote real water savings?
A first step could be accurate accounting of basinwide water use.
Water accounting analyzes use, depletion, and productivity of
water at the basin scale*. Accurate accounting and measurement
of water use can help identify opportunities for water
savings, increase water productivity, and improve the rationale
for water allocation among uses*.”

At Net Irrigate, we take water accounting seriously.  Our telemetry solutions coupled with our web based reporting and data analysis tools store up to five years of historical data and provide high degrees of granularity.  Our graphical components make analyzing data easy.  What good are flow meter and conservation programs if stakeholders cannot have timely access to data?  Proactive measures can better be taken when data is in workable formats and free from lags.

Tools for Measuring Fertigation

The October 15th Southwest Farm Press Article entitled System, nutrient management are keys to drip irrigation success discusses one of the caveats of drip irrigation. As a possible remedial strategy, the article suggests the process of injecting fertilizer through your drip irrigation system.

While some best practices were suggested in the article, technologies for measuring fertigation were not discussed in great detail. Metering technology can be quite beneficial in applying proper amounts. SeaMetrics manufactures Low-Flow Fertigation meters that can be used in conjunction with popular systems such as those from Agri-Jet. The beauty of these meters is that they are fully compatible with the NetIrrigate® Telemetry Box Version 3.0. In addition to monitoring your water application amounts to each zone within your drip irrigated field, you can also monitor your fertigation at www.netirrigate.com. Since our new telemetry box offers dual meter inputs, irrigation AND fertigation data can now be at your fingertips.
