Tissue Testing Field Crops requires Cautious Approach
Tissue testing is a valuable diagnostic tool for helping agronomists ‘listen to plants’. However on its own, test results can lead to misinterpretation of the numbers as they provide a snapshot of what the plant status is at that moment which can be impacted by things like drought, pests, diseases, plant injury, poor soil structure […]
Read MoreThe Value of Straw
With more talk of bio-energy or bio-materials like the proposed MDF plant for central Alberta, growers may ponder whether it’s worth selling the straw to generate extra income from your straw crop acreage. One way to value straw is simply on what the market place is offering. The other is the opportunity cost based on […]
Read More4R Potash Deficiency & Drought – a Double Edged Sword

Potassium is important in many plant functions including water use efficiency and plant cell turgor pressure. So, when plants cannot access potassium, water use […]
Read MoreTop Soil Sample Depth Needs to be Consistent
Quality soil sampling is critical to correct interpretation of results. We stress to clients this point and write often about collecting and interpreting results. This has become even more critical as agronomists and growers adopt more precision 4R nutrient management. A few years back AgVise lab completed a demonstration project on the effect of sampling […]
