Manage your objectives

Identify high potential/risk fields in season

For wheat and grain maize

See the yield gap as well as water and nitrogen stress indices for the coming week.

For maize silage

  • expected harvest date (standard – 32% DM)
  • the predicted yield (in tonnes of DM) displayed

These two pieces of information enable the user to organise the harvest and optimise the quality of the maize silage

It also makes it possible to anticipate a bad year and to obtain food or other fodder

Yield prediction

Regional or multi-farm yield forecasts are available from day one of the season. Get the best quality yield estimate from Cropwin up to 2-3 months before the actual harvest.


2.6 t/ha = Predicted Yield

Yield prediction for the field knowing cultural practices entered in Cropwin.

+2.3 t/ha = Potential yield

Maximum yield still possible to achieve with optimized water and nitrogen applications.

Before the season, use Cropwin to define the optimal fertilization and irrigation programs (2.6 t/ha here).

During the season and thank to daily updated weather data, refine the program and make adjustment to close the yield gap (2.3 t/ha here). Cropwin allow user to refine these programs and make adjustment to close the yield gap (2.6 t/ha + 2.3 t/ha here).

Advantage


Growth stages

Anticipate vulnerable stages and periods of field

Weather data

Visualize rainfall, temperature, global radiation and growing degree days on the field.

Water stress

Visualization of soil water content and water stress during season. Red and light blue zones indicate water deficit situations. Adding of irrigation will change water stress and yield prediction.

Nitrogen stress

Allows to visualize the nitrogen supply capacity of the soil in relation to the demand of the plant. Nitrogen fertilization will decrease field ROI if the yield limiting factor is water. Managing both water and nitrogen help to understand if and when it’s necessary to apply nitrogen fertilization.

Use-cases

Fictive case


On a field of maize silage

Planted on 04/15/2020 with no cultural pratice applied. Predicted yield is 9t/ha and yield gap is 8.6 t/ha. For this fields, there is a clear interest in optimizing cultural practices to close the yield gap. Nitrogen chart indicates a high level of stress starting early in crop cycle (before 3-leaf stage).

1/2

On the same maize silage field

Following the application of nitrogen fertilizer (after crop emergence), nitrogen stress is reduced and predicted yield is increased to 11.1 t/ha. Yield gap is also decreased to 7.4 t/h, accordingly. Yield gain of this fertilization is 2.1 t/ha and corresponding ROI is 299 euros/ha.

Clients testimonials


Crop model teaches lesson

When looking at a crop model for maize, there’s one glaring message that stands out: The crop needs more nitrogen in later life cycles that most users may be providing. The second conclusion? Fall application of nitrogen may not have the following-year benefit many hope to achieve.

Jay Culver, technical agronomist, South Dakota Wheat Growers, works with users  raising more than wheat. During a demonstration of the WinField United Field Forecasting Tool, he observed that nitrogen use for maize— as an example — does currently match how users are putting it on.

What we’re seeing is that splitting that nitrogen application is boosting efficiency,

During a demonstration at a recent national Answer Field tour event for WinField United, maiz that got a spring application of 75 pounds of nitrogen, followed by a midseason 75 pounds, was outperforming fields that got 300 pounds in one shot ahead of planting. That’s a 150 pound savings per acre in nitrogen applied.

Crop modeling tools like the Field Forecasting Tool can further demonstrate ways to boost nitrogen efficiency.

2017

In 2017, Valley United conducted a beta test on a 160 acre cornfield using Winfield’s Field Forecasting Tool® (FFT). This grower typically does a side-dress application with 30 units of nitrogen in late June, around the V4-V6 stage.

Within FFT, you can create heat maps that calculate yield responses with different application dates and rates, so we ran a scenario the day they started side-dressing.

FFT was telling us if we delayed the application to after July 4th (about V6-V7), we would see a greater response. So we decided to split the field into two 80s, and side-dress the north 80 with a ‘normal’ timing (end of June), and the south 80 we would delay application until after the Fourth.

When harvest came and yield data was analyzed, the south 80 did in fact produce higher yields with the same amount of fertilizer, and was within a couple of bushels of what FFT had projected. By following FFT’s recommendation and delaying their side-dress nitrogen application by about a week that year, they increased their yield and revenue/acre.
