1. What is efficient farming?

A new report commissioned by Fertilizer Canada and the Canola Council of Canada shows increased adoption of 4R (right source, right rate, right time, right place) stewardship practices could result in a 14 per cent reduction in greenhouse gas emissions from nitrogen fertilizer — approximately halfway to the Canadian government’s 30 per cent reduction target for 2030.

Farmers frequently need to make challenging decisions (right decisions, right time, right place, , and right amount) that impact crop productivity, profitability, and sustainability. Making the right decision is often the difference between profit and loss. Farmers require hard numbers to allow them to rapidly make informed decisions. However, much of this information is collected through laborious manual observation, guesswork, or subjective data collection. For example, crop yield estimation can help producers, agronomists, breeders, researchers, insurance companies, policy makers, and governments to rapidly make informed management and financial decisions. Monitoring and estimating in-field crop yield in real-time is now required more frequently due to climate change. However, obtaining accurate yield estimates at the individual farm field level still rely on inaccurate, unpleasant, and time-consuming manual observation.

Timely and accurate crop yield estimation can increase a farmer’s gross revenue by 10-30%. Below are three business scenarios.

a. When planning a sale, grain companies contact railways as far ahead as three months to confirm that they will have the capacity to move the grain. It is not uncommon for wheat prices to be 10% higher (or more) outside the harvest window. Therefore, producers usually pre-sell a portion of the wheat crop prior (possibly in July) to the harvest to obtain a favorable price. Producers need to estimate the approximate crop yield in a wheat field before they can make an informed decision on how much to charge a prospective buyer. As the market price can drop any time, producers need to know the crop yield in their field within one day. However, rapidly estimating a crop yield is a challenge.

b. Fungicide application is costly, but under the right conditions, with the right timing, it can increase a crop yield by more than 30%. With SGA technology, a high-resolution growth stage map can be created for a wheat field and combined with a high-resolution estimated wheat yield map. This information tells producers where and when to apply fungicide, and to apply fungicide only to certain areas of a field, or to time application differently in separate areas of a field to increase chemical efficacy or decrease chemical use. Our technology could result in a 10% reduction in fungicide applied to Saskatchewan fields.

c. The Canadian government plans to reduce nitrous oxide (N2O) emissions from synthetic fertilizer by 30 per cent in 2030 relative to a 2020 baseline. The amount of nutrients used by a crop vary with the yield.  A big crop requires more nutrients than a small crop. Since many of these nutrients may be lacking in the soil where the crop will be grown, they must be added to the soil by the farmer. It is therefore desirable to estimate as accurately as possible the yield of the crop, so that appropriate nutrients, generally applied as a commercial fertilizer, can be provided. SGA technology can increase fertilizer efficacy and decrease fertilizer use.

2. The current ‘quick and easy’ practice of crop yield estimation

Methods:  To estimate crop yield in a field, producers and agronomists randomly select and manually count the number of wheat heads from a specific length (e.g., 3 ft) of plant row in various spots around a field. By counting kernels on heads, determining the distance between rows, and applying each measure to a formula, yield can be approximated.

Problems: (1).  Crop yield estimation relies on unpleasant and time-consuming manual observation. (2). Rapidly estimating crop yield is challenged due to the time it takes and the difficulty in selecting sufficient representative samples. The sustained manual work causes miscounts, and fields are seldom uniform; drought usually accentuates field yield variability.

3. Super GeoAI Smartphone Solution

Solution: Users walk with a smartphone to take several photos per representative location around a field. Our mobile application can count and label wheat heads, and calculate crop yield in the photo within three seconds, with an accuracy approaching 100%. Once users take a certain number of photos, our app can give users approximately accurate crop yield estimation (such as bushels per acre) in a field.

The  smartphone photos will be first processed to calculate crop yield by our fast GeoAI algorithms in the smartphone. If the internet and Wi-Fi are available, the photos can be automatically uploaded to a cloud platform and processed to calculate crop yield and crop growth stage using our advanced GeoAI algorithms. If the advanced algorithms have better results, it will update the local result. In addition, users can login to the cloud platform to visualize the accuracy and easily fix any AI mistakes to achieve 100% accuracy, if necessary.

The app immediately calculates the crop yield in each photo and the average crop yield in the whole field. Click Here to download the original high-resolution video.

4. Super GeoAI Drone Solution

Solution 1: While our mobile application can achieve approaching 100% accuracy for each photo, producers may be unable to randomly adequate representative samples throughout an non-uniform crop field.  Our GeoAI-driven drones have the ability to rapidly and randomly sample throughout a field, providing a higher level of assessment accuracy over walking and selecting spots manually in the field. Our GeoAI-driven drone can automatically take off from farmers’ backyard, fly to the crop fields and take photos. Upon task completion, the drone will automatically return to the starting location. The drone image (e.g., The file size of a DJI mini 2 drone image that covers 30sq ft is about 5 MB.) will be automatically uploaded and processed to calculate crop yield by our  GeoAI algorithms in our cloud platform, given that the internet and Wi-Fi is available. Users can also manually upload drone images into our cloud platform.

Users can upload drone images in our cloud platform to calculate the wheat crop yield in the images. Below is a demo video. Click on the three-dot icon at the lower right-hand side of the player to download the original high-resolution video.

Solution 2: Random sampling throughout a field provides higher assessment accuracy than walking and selecting spots in the field manually. However, fields are seldom uniform and drought usually accentuates field yield variability. Integrating the traditional vegetation indices and traditional crop yield prediction model into our GeoAI-driven models can create high-resolution estimated yield maps and growth stage maps of a field. We are developing our advanced GeoAI models for this solution.

The following drone image shows the variability of crop throughout a field, where some areas have a much higher wheat yield than others.

The following drone image shows the SGA’s own non-uniform wheat field in 2022. The areas with higher yield and later maturity have not yet been harvested. A drone can take photos of the areas about 30-100 meters above ground and our GeoAI algorithms can accurately calculate these polygon areas.

The following video shows that  the Dji Mini 2 drone is collecting wheat head data about 2-3 meters above ground. Click on the three-dot icon on the lower right-hand side of the player to download the original high-resolution video and play.
