Trial Analysis

Understanding your on field trials in depth

Benefits of Trial Analysis

There are many variables that can effect your field trials. We look at multiple variables that may influence your trial such as productivity zone or soil nutrient levels.

Deveron’s Trial Analysis allows for clear analysis of the important variables specific to each field and how they effect yield. This analysis can be used for decision making in prescriptions, fertility planning, hybrid choice and product use in the future.

Varietal Trial Analysis

Every variety responds differently to each production zones of a field

At Deveron we dig a little deeper to ensure our conclusions are based on all the information available to us. The first step we take is to incorporate productivity zones into our analysis. Given that varieties have been bred for different qualities, we know that they respond differently to environmental conditions, and soil quality plays a role in that.

How can plot data help you decide which variety will perform best in your field?

This table includes the total acres of each productivity zone within the field. By multiplying the average yields by the total number of acres in each zone, we can estimate which variety would maximize yield across the whole field.

Placing variety performance trials in all productivity areas is critically important to ensure accuracy of data results

Different varieties are bred to excel under different circumstances. As a result, summarizing yield averages over a test strip can miss important information and skew results. Understanding how each variety performs across different production zones is one way to improve understanding and help inform data driven decision making.

Agronomic Insights FAQs

A: Polygon (zone) are areas drawn on a field based on soil type, topography, yield variability, drainage, fertilizer applications or grower knowledge of the field. The information about the variability across the fields is used to create field management maps. The best zones come from multiple layers of data that when layered on top of each other reveal to us the true variability across the field.

A: Variable Rate Prescriptions are field specific maps created to allow for different rates of product to be applied to different management zones of the field. The prescriptions are computer generated maps that are uploaded to the tractor monitor. These prescriptions will work as long as there is a rate controller on your tractor. There are variable rate prescriptions that allow for planting of a specific rate per management zone and then there are variable rate prescriptions that add in a validation layer that allows you to test different rates in those management zones. The validation component of the prescription is no extra work to the grower and allows for a return on investment analysis as well as varietal or treatment comparisons for each of your management zones.

Variable rate prescriptions can be used for seeding, applying nitrogen, fungicide or any in-season treatment, just to name a few.

A: When creating variable rate prescriptions there are many different data layers that can be used to understand the production areas of the field and what are the fields’ different management zones. There are many different data layers that need to be considered, such as: yield data, elevation, geospatial drone imagery, historical satellite imagery, bareground imagery, soil test data, fertility program or seed company research history. When creating a prescription the knowledge and understanding of how the field performs is most important. Depending on the prescription that is being created the best data layers are collected from your tractor monitor, data management software, ag retail or soil lab. These layers are uploaded into a computer program that allows for management zones to be created, such as Climate Fieldview, Granular Ag, Proagrica Summit and AgLeader SMS. There are many different software programs out there that can create management zones. There are fewer programs that allow for the zones to be edited and customizable check blocks added to the zones. A Deveron precision ag specialist will be able to create these prescriptions in the computer software using the applied rates that they will discuss with you ahead of time. It is important to ensure that the prescription that is created is able to be exported in the file format that will work with your equipment. Most programs are able to export in multiple formats. Be sure to brush up on your equipment needs and what file format is compatible with it when deciding to utilize variable rate prescriptions on your farm.

A: Variable rate prescriptions allow you to manage your farm according to the variability across that farm. At this point we’ve all probably heard the saying ‘manage each acre’. Variable rate application is a direct way to do this. The value of managing your field in a variable way comes from allowing you to address the needs of your field at each location instead of managing to the average. This results in optimizing inputs (4R philosophy), as well as optimizing associated input costs, which in turn means making each dollar go farther in your operation.
