20 Years of Field Data Video Series

Part 1: Overview and PH

Greg Reisz, president of E4 Crop Intelligence, talks about the collection of field data collected by E4 for the past 20 years. In Part 1, he goes over the background of the study and how E4 uses this data to make better decisions for you as a customer, also in this video Greg goes over the collected data for pH.


Part 2: Phosphorus

In Part 2 of the Field Data Series, Greg Reisz talks about Phosphorus and the noticeable decline in levels found from the yield data that has been accumulated in the past 20 years.


Part 3: Corn Price

In Part 3 of the Field Data Series, Greg Reisz talks about Corn Price and the fluctuations in price and yields from the collection of field data from the past 20 years, and what E4 recommends to get optimized results from your yield.


Part 4: Potassium

E4’s soil and agronomy experts act as the boots on the ground in your field. We offer midwest independent soil sampling services with a national reach. E4 provides valuable data and farm intelligence for a range of crops across the U.S., working with growers from Idaho to Iowa.


Part 5: Precipitation

We offer precision ag products and services in Iowa, Nebraska, and across the U.S. that help you use data to optimize your ROI. We have worked with precision equipment for almost 20 years, giving us the expertise and experience to help you find the right equipment for your operation.


Part 6: Soybean Yield

Our Benchmarking service allows you to see how your operation stacks up against others of a similar size and type. With access to a large data pool of private growing data (identities kept confidential), we can bring fact-based insights that can improve your farming or management practices and identify growth opportunities.

Part 7: Organic Matter

In Part 7 of the Field Data Series, Greg Reisz talks about Organic Matter (OM), the increase in levels, and what can be done to continue and improve yields, by looking at OM and other data collected in the past 20 years.

Part 8: Sulfur

In part 8 of the Field Data Series, Greg Reisz talks about Sulfur (S). E4 covers the small overall growth that can be seen in the past 20 years and expands on how there has been a decrease in levels in recent years. Looking through collected crop yield data is also essential to know what to apply to your field to maximize yields.

Part 9: Zinc

In part 9 of the Field Data Series, Greg Reisz talks about Zinc (Zn) and how in earlier years showed more dramatic levels, and in the past 15 years levels show Zinc has become more stable with some decrease over time.

Part 10: Summary

Our soil and plant tissue testing bring value to growers across the country, collecting data and offering insights that will improve your farming practices. By combining sampling and agronomic testing services, we can track the transition of nutrients from ground to grain.
