This article originally appeared in the AGVISE Laboratories Fall 2022 Newsletter Soil test results are only as reliable as the soil samples collected in the field. A crucial part of soil sample quality is consistent sampling depth. This is important because all the soil test calibration research and fertilizer guidelines for non-mobile nutrients (e.g., phosphorus, […]
This article originally appeared in the AGVISE Laboratories Winter 2022 Newsletter Farmers, like all business owners, are profit maximizers: things are good when revenue exceeds cost. Things are even better when the difference between revenue and costs is substantial. The math behind increasing profit is simple: reduce costs, increase revenue. But, the difficult part is […]
It’s probably more than you think. So far, the residual soil nitrate-nitrogen trend following corn is much higher than average across the upper Midwest and northern Great Plains. This follows the same trend set by the 2021 wheat crop. For many growers in the region, the hot and dry growing season has resulted in high […]
The fall harvest season is a busy time of year. Farmers need to finish harvest, apply fertilizer, and complete any tillage operations before the long winter sets in. Another field operation that needs to be completed within this flurry of activity is soil sampling, and sampling timing is crucial to getting quality and consistent soil cores. […]
The 2022 growing season may seem like a long way off, but spring will be here before we know it. In fact, many growers are already making (or have made) crop choices and seed variety decisions for 2022. One factor that must be considered when making crop and variety selections for 2022 is residual soil […]

AGVISE Laboratories is always trying to make soil sampling easier. Since 2011, AGVISE customers have enjoyed submitting soil samples online through our AGVISOR platform. AGVISOR is the online platform that allows you to submit soil samples (conventional, grid/zone, and soybean cyst nematode samples); save grower and field information (so you don’t have to fill it […]
Plant sampling season is in full swing. Agronomists submit plant samples for analysis for a number of reasons: to confirm visible nutrient deficiency symptoms, to detect “hidden hungers”, and to monitor or fine-tune fertilizer plans. For whatever reason you plan to take plant samples, here is a quick refresher on sampling, storing, and shipping plant samples to AGVISE Laboratories. Sampling […]
AGVISE Laboratories Spray Water Analysis Hard water is a fact of life for those of us in the northern Great Plains and Prairie Provinces. It is why our homes have water softeners, why our well water tastes funny (or delicious), and one reason we need to add AMS (ammonium sulfate) or UAN to our spray tanks to optimize weed […]
Plant analysis is a valuable tool for managing plant nutrients and troubleshooting agronomic problems. Being certain that a specific plant nutrient is causing deficiency symptoms is difficult with visual symptoms alone. Many causal agents unrelated to soil fertility can cause symptoms that appear to be nutrient-related. There are also some plant nutrient deficiencies that are impossible […]
