Irrigation and Energy Conference

Farmers work consistently to reduce operating costs while maintaining and improving crop yields. Energy and water use are two operating costs that farmers can control.
The California Association of Resource Conservation Districts will host a one-day conference to help farmers reduce energy use and increase water use efficiency. It will be held at the AgTAC Energy Center in Tulare.

The conference will provide information and practical experience on numerous innovative precision agricultural technologies. It will highlight recent successful introductions of mechanized irrigation systems.
The morning program offers an overview of emerging "hot button" issues in air and water quality that the agriculture industry faces. These will include groundwater pumping and cost-sharing funds from the USDA. Air and water quality specialists will offer updates on ag-related air and water quality regulations.
Guest speakers will discuss an overview of precision agriculture technologies.
Further discussions will cover mechanized center pivot and linear overhead irrigation systems. These systems are being adopted because they offer high application uniformity, increased automation, and low reliance on labor.

Outdoor Security System

This is the first outdoor security system that requires no electricity. It uses sensors and trap sensors to detect intruders and risk situations. With no need for building works or channelling, since the technology it uses is completely cordless.

The system cosists of an electronic unit and a number of sensors and trap sensors (three different types) plus, if neccesary, an actuator with up to 50 components per installation. The coverage range can be up to 50 metres between each trap sensor and the Electronics Unit. Remote communications are achieved by using a SIM card from any operator, slotted into the Electronics Unit. Optimal power management means that the system can send one alarm every day for a whole year.

Trap sensors for detecting people

With conventional security a large number of electronic devices are used, but they're not traps. They are detectors that make no attempt to be hidden: barriers, cameras, volumetric devices, etc. Burglars are aware of their existence and so try not to be detected. They are intended to detect intruders in closed compounds.

Our system can detect and surprise intruders anywhere out in the open, applying logic: if someone wants to steal they must pass along a certain path, approach a certain machine, enter a given site, open this box, go up those stairs, etc.

Sensors for risk situations

Issuing an alert if an animal leaves a fenced area, when the water level is too low or too high, when somewhere is flooded, if there is a power outage, or for any other application without the need for a power supply.

Applications

For tracks, fencing, gates, farm machinery, irrigation wells, barns, silos, pens, tools, etc. From now on traps can protect the things that previously were at risk of being stolen or damaged.

Big return in corn

When it came to deciding whether or not to spend $120,000 to install a center pivot in an area where the systems are a rarity, “We had to do some serious thinking,” says John Grant, who farms hill land in north central Mississippi.

John Grant, and his son, Kenneth, say the difference in corn yield over dryland in 2008 helped them pay almost half the cost of installing a center pivot system on a 170-acre field. They’re hoping to recoup the rest of the cost this year.

Drilling wells in the area is an expensive — and often futile — proposition, given the depths required to try and get adequate water to run an irrigation system. Grant and his son, Kenneth, who farms with him, had a go at drilling a well on a field where they planned to grow corn in 2008, but called it quits when they got to 600 feet and still couldn’t get sufficient water to run a center pivot. They weren’t ready to give up on irrigation, though.

“Bogue Creek runs along one edge of the field,” says John. “You can walk across it in most places and not get too wet, and just to look at it, you wouldn’t think there’s enough water flow to support a quarter-mile center pivot. But, it doesn’t go dry in the summer, and when we checked the flow, it averaged 3,000 gallons per minute. The pivot would require only 1,000 gallons per minute.

“We worked with the Big D folks at Greenwood, Miss., to design a Valley system that would pump water from the creek, uphill through an underground line, to the pivot". “We had to pay the electric company $9,600 to run a line to power the pump in the creek and the pivot, but when we looked at operating costs, electricity was much less than diesel.

“We ran the system 16 days last year, and we’ve already used it several times this season. It takes 36 hours to make a full circle on 167 acres, putting down a half-inch of water.”

When harvest time came, says John, any reservations they may have had about the irrigation investment vanished. “We averaged 195 bushels on the field, and the yield monitor on the combine was showing some spots with 230 bushels. On areas outside the pivot, we averaged 54 bushels. With the price we got for our corn, we figure we recouped half the cost of the system in just one year". “If corn prices hold this year, and we’ve already got a lot of it booked, we’ll likely make back the rest of what it cost us. As soon as we get this pivot paid for, we’ll look at putting in another.”
