MANAGING SOIL STRUCTURE AND QUALITY Physical & Chemical Management Practices to Maximize Soil Quality By DR. KARL WYANT, Vice President of Ag Science, Heliae Agriculture, Board of Directors, Western Region Certified Crop Advisers You may have heard or read about improving your soil health or soil quality over the last year as this area of field management gains more attention. But what exactly do the terms mean and how can you incorporate the concepts in your day-to-day soil management practices? In Part 1 of this article series, the physical and chemical connection to optimizing soil quality by focusing on the structure of your soil will be explored. Soil Quality and Health Soil quality has broad application to your farm. It refers to how well a soil functions physically, chemically and biologically and how well it does its “job” (Fig. 1, page 6). For example, a forest soil has a different job than a farm soil, and soil properties can be measured on how well the soil is performing (e.g. soil structure). Figure 3: The soil on the left has poor soil structure while the soil on the right has excellent aggregation and structure. As a result, the two fields have substantial differences in soil quality and their ability to support optimized crop growth (photo courtesy K. Wyant.) Many factors influence the soil quality on a farm and are summed up in Figure 2, on page 7. In this article, the focus will be on the physical and chemical management practices that maximize soil quality, expressed here as soil structure (Fig. 3).

Potassium AN Essential Nutrient for tree Nuts. Almonds remove roughly 91.2 pounds of K 2 0 per 1,000 kernel pounds each season. Replenishing this potassium for the next season is crucial as it plays a vital role in tree nut development and disease resistance. The efficient liquid formulation of KTS ® allows for application via drip or sprinkler irrigation. Avoid potassium deficiencies. Apply KTS.
