Soil sampling your fields is a no-brainer anymore. But how can you do it cost-effectively, accurately, and with minimal error? By taking advantage of already common technology – GPS. GPS-referenced sampling is well known among professional agronomists and farmers and has been used for many years to make sampling more precise and consistent over time in soil fertility management.
To see the trends of macro and micro-nutrients in soil, samples must be taken annually from the same areas of the field to be representative. Knowing the trends allows us to estimate the movement of nutrients in and out, making necessary changes in fertility management for both short- and long-term strategies. Be sure to use professional GPS equipment to reduce GPS error. Our smartphones may have an error of 5-10 meters under normal conditions. For accurate sampling, it is important to stay within 5 feet of your sample GPS position.
Another important part of the soil sampling process is the sampling equipment. Taking the exact same amount of soil from each spot ensures consistency and soil test accuracy. So, put your shovel away and use standardized sampling equipment.
Alternatively, let professionals do the job. Highly trained professionals who sample thousands of acres every year can make the sampling process smooth and simple for you with little room for error. Professional and clean sampling equipment, adherence to clubroot protocol, and quality control are all good starts for the new crop season.
In Manitoba, Saskatchewan, and Alberta, we have local sampling teams led by senior agronomists at your service.
