  • Comparing effects of herbicides, fertilizers, and tillage on the soil

    In a past post, I argued for the use of an herbicide instead of tillage to kill a soil-building cover crop. My post was mostly observation of the damage of tillage on the soil as compared to the lack of damage, at least visually, from the herbicide. But others suggested that herbicides may not be as benign in the soil as I portrayed them. Here is the latest science on the topic.

    A series of reviews have been published on the effects of herbicides on the soil, starting with Bunemann et al. in 2006. They concluded, “The herbicides generally had no major effects on soil organisms.” More recently, a review by Rose et al. (2016) found, “Overall, the majority of papers reported negligible impacts of herbicides on soil microbial communities and beneficial soil functions when applied at recommended field-application rates.”

  • Resiliency achieved by sustainable agriculture

    December 5, 2016

    This year CSANR sponsored registration for several WSU students to attend the Tilth Conference.  We will be posting reflections written by the students over the next several weeks. Please feel free to comment and give these students your feedback.

    corinaMy name is Corina Serban, and I am currently working towards my Master of Science in the Horticulture department at Washington State University. Attending the Tilth Conference for the first time gave me an ideal opportunity to network with other professionals and learn a lot from the workshops presented.

    This year’s conference focused on change and resiliency. It brought ideas and people that inspire organic and sustainable farming. I personally found this event to be valuable to me as a Horticulture graduate student. Through my research, I want to contribute to the development of pre- and postharvest management strategies to reduce physiological disorders related to calcium deficiencies on ‘Honeycrisp’ apples. Even though my research approach is on conventional orchards, I have always had a passion to know more about organic and sustainable tree fruit production. Since I was a kid, I enjoyed being in the natural world and had my own garden. I grew up with values that show how important is the respect for the land and the care that is an integral part of growing healthy and nutritious crops. After sharing my ideas with others who were passionate as well about organic and sustainable agriculture, I felt like I was in the right place.  I could express my opinions and learn about new ideas and technologies in sustainable agriculture.

  • Crop rotation: In praise of deliberate, sequenced disruption of natural systems

    December 1, 2016

    For years, researchers have been looking to polycultures, biodiversity in space, as a way to improve agriculture (Trenbath 1974; Tilman et al. 1997; Cardinale et al. 2011; Finney and Kaye 2016). Behind this research is the idea that nature is the best model for agriculture. Because we find that nature is generally a polyculture, we should mimic this biodiversity on the farm. Natural is now viewed as the best option. Today, however, I want to commend a most unnatural practice, crop rotation.
