  • Washington organic apples – nearly a billion strong!

    It is apple harvest time again in Washington State, albeit about two weeks earlier than normal in most places. This will be a large crop overall, and probably a record crop for organic apples. The projection is for a harvest of just over 11 million 40-pound boxes of organic apples. At 88 apples per box (a typical size), that’s over 950 million organic apples.  And while this sounds like a lot, if everyone in the US (say, 300 million people) ate one apple a day, that supply would be gone in less than four days. Still, demand is growing by around 10-12% per year, according to the annual surveys done by the Organic Trade Association. Based on data from grocery store sales, apples are the number two fresh fruit sold by value (behind berries) for both conventional and organic. A major food retailer reported that their sales of organic apples increased nearly 50% in 2015 over the previous year, a huge jump. And average organic apple prices received by growers hit record highs last season. The total value of the packed organic apples was just under $400 million, with 70% or more going directly to growers. This is a substantial contribution to the state’s economy.

  • Orchard Netting: A Catch All for Climate Change Adaptation

    August 22, 2016

    Brendon Anthony is pursuing a Master of Science in the Horticulture program at Washington State University.

    As a child in elementary school I learned that the two basic requirements for the growth and success of a plant are sunlight and water. However, as I have undergone further schooling and research, specifically in horticulture, I have learned how extremely simplified those requirements are. In reality, it takes numerous inputs and extensive management to steward the growth of a plant.

    Though sunlight and water are not the full picture, they are certainly foundational. In the face of a changing climate with more extreme and unpredictable weather, they are resources that are becoming more and more challenging to preserve, utilize, and control. How to best manage sunlight and water is being investigated and tested by the Pacific Northwest tree fruit industry. This is an industry that relies on consistent temperatures both in the winter to facilitate dormancy, and during the growing season to prevent frost damage or sunburn. It is an industry that uses gallons upon gallons of water to ensure a high yield. So, how does an industry so dependent upon these crucial resources react to a rapidly changing climate, all while maintaining sustainability in their pocket books and in their surrounding environment?

  • Biosolids – understanding benefits and risks

    Biosolids?  Yes, that means sewage sludge.  Well, sort of.  But before you say YUCK and click off the page, let’s start with what they really are: biosolids are the materials produced from digestion of sewage at city wastewater treatment plants. They are rich in plant nutrients such as organic carbon, nitrogen, and phosphorus, and can be applied to wheat, alfalfa, and timber land for plant fertilization and soil conditioning. When biosolids are applied at rates that meet plant nutrient needs, farmers and researchers are seeing crop yields equal to or greater than those seen with synthetic fertilizer. Applying biosolids as fertilizer also allows them to be recycled for a useful purpose rather than disposed of in landfills or incinerated.
