Drip Irrigation Isn’t Just for Young Hazelnut Orchards Anymore

By: Danita Cahill, Contributing Writer

The census is in: drip irrigation produces bigger hazelnut trees faster, more nuts sooner, and fuller, heavier kernels. With drip irrigation, hazelnut production is now possible in dry soils with low-clay content, instead of only in historically-used prime soils. “Drip irrigation is increasingly being adopted. It really has enhanced orchard establishment,” said Nik Wiman, Assistant Professor, Orchard Crops Extension Specialist at Oregon State University (OSU) Wiman Lab. “Grows trees a lot faster. We’re seeing nuts by year four.” Benefits of Drip Irrigation on Established Trees Jeff Newton, farm manager for Crimson West/Christensen Farms in McMinnville, Oregon, got in on the ground floor with hazelnut drip irrigation. He partnered with OSU extension service and Crop Production Services, and in 2011, installed a drip system into a 100-acre orchard of two-year-old Jefferson trees. Like Wiman, Newton sees a higher yield sooner with drip irrigation. Dryland trees in poor soil might take anywhere...

Irrigating Young Hazelnut Trees

By Cecilia Parsons Associate Editor

As Oregon’s hazelnut industry continues to expand, so does knowledge about the benefits of irrigation for optimum growth of the trees. Jeff Newton, farm manager at Crimson West/Christensen Farms in McMinnville, said thinking has changed as hazelnut value has increased and growers are looking for earlier harvests and maximized yields. Historically, a dry farmed crop in the Willamette Valley, hazelnuts are now being produced in a variety of soils and in new locations. “We used to grow dry land filberts, now we grow irrigated hazelnuts,” said Newton. “It’s a totally different crop.” Ongoing research at Oregon State University (OSU) is aimed at helping hazelnut growers with irrigation scheduling, soil moisture testing and choices in irrigation delivery systems. While the evapotranspiration rate for almonds has long been known, there is no established rate for hazelnuts—mature or young. That is another piece of helpful information Newton said should be coming soon. Newton...

FSMA: Preventative Controls for the Nut Industry

By Safe Food Alliance, Contributing Writer

For our second installment in this series on the Food and Drug Administration’s (FDA) Food Safety Modernization Act (FSMA) series, we’re going to talk about the “Preventive Controls” rule, which is the main rule for food processors. It’s similar to the Hazard and Analysis Critical Control Point (HACCP), with some notable differences which we’ll address below, including some specific requirements that you may not have seen before. Who’s Covered In general, facilities which register with FDA under part 415 of the FD&C act (that is, food processors) have to comply with the rule, unless specifically given an exemption. There are a few available exemptions based on specific food industry sectors such as meat processors or alcoholic beverage companies, which already have other regulations in place, but there are no specific exemptions for the nut industry. But there are some modified requirements for certain situations such as a very small company...
