4 Steps to Make the Most of Zone Soil Sampling
Build a plan.To develop a sampling plan, start by deciding what your yield goals are based on what you know about each field. Make sure you’re taking enough samples to account for field variability. The more data you have, the more informed your decision-making will be. Also, be sure the lab you use is accredited and find out what is included in the analysis report. Solum is an agricultural testing lab that uses state-of-the-art equipment and field moist analysis to give you the most accurate soil sampling results so you can take action to improve yield potential.
Account for field variability.Ag technology, including the R7® Tool can help you identify management zones for sampling. You can pick from satellite images (including yield maps and field variability maps) that best represent your fields, and the R7 Tool will generate a satellite-derived management zone (SaMZ™) map to help you see variations in production potential.
Make decisions.After you’ve taken soil samples in the defined zones, use the results to establish fertility plans. Knowing which zones have the highest productivity potential can help you focus your fertilization applications to areas where you’re more likely to get the highest return on your investment. Based on results from soil and tissue sampling, you can build variable rate fertilizer prescriptions to stretch your dollars further.
Make in-season adjustments.Soil sampling is a valuable tool, especially when it’s used to implement in-season practices. Comparing soil samples with plant tissue samples can indicate how efficiently plants are taking up nutrients. This helps you identify agronomic challenges your crop may be facing and can help focus in-season nutrient amendments.
