Collapse ▲Proper Sampling for Nutrient Management
Whether you’re using animal waste or inorganic fertilizers as the fertility source for your crops, sampling (waste, soil, and tissue) is an important tool in your toolbox. Some of these samples are taken as a regulatory requirement, while some help you make management decisions or diagnose issues in real-time to take in-season corrective actions. This collection of videos and handouts will help you understand the proper way to collect these samples to maximize their benefit and improve nutrient management on your farm.
