*NEW* Drone Imagery Provides Valuable Insight on In-Season Cover Crop Growth

*NEW* Drone Imagery Provides Valuable Insight on In-Season Cover Crop Growth

Cover crop management depends on building and estimating biomass amounts, which can vary across field and management settings. This study used multi-flight drone imagery and the normalized difference vegetation index (NDVI) to map cover crop growth over three different winter seasons and compare it with spring biomass accumulation. Drone imagery can be used to enhance our understanding of winter crop growth, providing additional data to explain the resulting biomass across variable conditions.

*NEW* Evaluation of Urease and Nitrification Inhibitors in Western Canada

*NEW* Evaluation of Urease and Nitrification Inhibitors in Western Canada

The recovery of fertilizer nitrogen by crops in the year of application is usually cited as being about 50%, despite considerable efforts to improve nitrogen efficiencies in agricultural systems. The use of fertilizer additives containing urease and/or nitrification inhibitors may improve fertilizer N efficiency. This was evaluated in four experiments conducted at multiple locations across the Canadian Prairies.

*NEW* Getting Support for Adoption of Climate-Smart 4R Practices

*NEW* Getting Support for Adoption of Climate-Smart 4R Practices

Nutrient management, particularly for nitrogen, plays an important role in improving the carbon footprint of crop production. Many programs have recently expanded their offerings or funding levels of incentives to farmers to adopt more climate-smart nutrient management practices. These programs provide opportunities for crop advisers to accelerate adoption among their clients of 4R practices that reduce greenhouse gas emissions and support soil carbon sequestration. The intent of this article is to provide a broad description of the programs available and the practices most likely to be effective.

*NEW* Improved Management of the Bermudagrass Stem Maggot

*NEW* Improved Management of the Bermudagrass Stem Maggot

The bermudagrass stem maggot (BSM) severely damages bermudagrass pastures and hayfields throughout the southeastern United States every summer. This management guide can help forage managers and consultants identify BSM damage and the pest. Pyrethroid insecticides can reduce adult BSM populations and yield loss when applied correctly. More research is needed to develop integrated pest management plans that include multiple suppression efforts. Fine stem lines are more susceptible to BSM damage than lines with thicker stem. Long-term solutions require new BSM-tolerant lines to reduce the demand that producers currently place on pesticides.

*NEW* Soil Fertility, Fertilizers, and Crop Nutrition: Past, Present, and Future - Part One

*NEW* Soil Fertility, Fertilizers, and Crop Nutrition: Past, Present, and Future - Part One

Society has made (and will be making) significant demands on agriculture in the not-to-distant future. Meeting future sustainability goals and environmental regulations while simultaneously continuing to meet requirements for food, feed, fuel, and fiber requires a firm understanding of how “we” have collectively arrived at our current status as it relates to our fertility principles and beliefs as well as the processes that address them. We have advanced far from the earliest thoughts on rudimentary plant nutrition to a sophisticated science of prescription crop nutrition. This article represents the first part of a series that intends to describe crop nutrition and fertilizers from where we have been to where the authors believe that we will likely need to be prepared to go if we are to support world demands into the foreseeable future.

*NEW* Soil pH and Nutrients: Everything is Local

*NEW* Soil pH and Nutrients: Everything is Local

Developed more than 80 years ago, the soil pH and nutrient diagram offers a quick reference that growers can use to gauge soil fertility and plant nutrition. At first glance, the relationship between soil pH and nutrient availability makes sense. Soil pH influences the solubility, concentration, ionic form, adsorption, and mobility of important plant nutrients. But this simple diagram hides the complexity of this relationship.

*NEW* Soil-Sampling Grid Size Considerations for Site-Specific Nutrient Management

*NEW* Soil-Sampling Grid Size Considerations for Site-Specific Nutrient Management

One of the most important aspects of site-specific nutrient management is precision soil sampling such as grid- and zone-based strategies to determine varying soil nutrient levels within a field. One of the most important considerations in grid soil sampling is the size of the grids as it affects both the sampling resolution and costs. Questions and concerns from growers about the effectiveness of different grid sizes in accurately depicting soil nutrient variability have become common recently, warranting an investigation into how grid size affects application accuracy and economics of site-specific nutrient management in the southeastern U.S.

*NEW* Some Concerns with Roundup Ready Spring Canola for Italian Ryegrass Control

*NEW* Some Concerns with Roundup Ready Spring Canola for Italian Ryegrass Control

Spring canola acreage in the Inland Pacific Northwest increased from just over 52,00 acres in 2017 to just under 191,000 acres in 2023. A large percentage of the spring canola acreage is planted to glyphosate-resistant (Roundup Ready) varieties. And while glyphosate has provided excellent control of Italian ryegrass in glyphosate-resistant spring canola, herbicide resistance can develop when a single site of action is used repeatedly over time. Thus, over the past two years (2022 and 2023), field studies were conducted to evaluate the benefits of using herbicides with different sites of action, both with and without glyphosate, for the control of Italian ryegrass in glyphosate-resistant spring canola.

*NEW* The Influence of a Soil Sample Core

*NEW* The Influence of a Soil Sample Core

It is critical that we are careful, not casual, when sampling soils. Many dollars of fertilizer decision rest upon a good soil sample. Several years ago, I was curious about the influence of the number of sample cores that comprise a composite soil sample. A review of several soil-sampling publications at the time recommended anywhere from 8 to 20 individual cores should comprise the sample. Thus, I endeavored to look at the statistics behind this suggestion. What I discovered is discussed in this article.
