Predicting crop yields in agriculture is a formidable challenge, determined by complexities of soil health, weather conditions, pest and disease, and management practices. While traditional methods of crop yield predictability were once deemed sufficient, today’s landscape is far more complex, where seasonal shifts alone no longer account for variations in accuracy.

Climate change has thrown a curveball to the equation, introducing a dizzying array of variables that challenge even the most seasoned experts. From unpredictable weather patterns and extreme events to altered growing seasons and evolving pest pressures, the delicate balance between sowing and reaping feels increasingly precarious.

But amidst this uncertainty, cutting-edge tools and nimble thinking have resulted in the innovative yield sampling approach as a bridgeable gap to improve the accuracy of crop yield prediction. This game-changer is an intelligence-based approach that brings together manual efforts, satellite monitoring and analyses, for more accurate yield computations.

What is crop yield prediction?

Crop yield prediction is the process of accurately predicting the potential yield of a specific crop, during a particular season in a given region. Accurate yield predictability requires scientific expertise, local knowledge about the region, and crops grown there. It is estimated using diverse data sets like weather patterns, genetics of the seed, soil properties, farm management and statistical datasets among others. A field tested multi-tier algorithm is applied to compute the yield estimates.

What are the benefits of yield prediction?

Precise yield predictability offers a multitude of benefits for agricultural stakeholders:

• Enhanced food security: Accurate yield predictions empower governments and organizations to anticipate potential food shortages and take early action. It helps them plan imports, manage export controls, and direct resources efficiently to ensure stable food security for its citizens.
• Enhanced farm management: With knowledge of anticipated yield, businesses can plan production, and optimize resource allocation (water, fertilizer, etc.) and pest control measures, leading to environmental sustainability, cost savings and higher efficiency.
• Informed decision-making: Data-driven yield predictions help make strategic decisions about planting appropriate crop varieties, sourcing, and harvesting, minimizing risks and maximizing profits.
• Financial risk management: Yield predictions inform insurance companies and financial institutions when assessing agricultural loans and crop insurance, allowing them to tailor their services. It mitigates risks for both farmers and lenders.
• Better market forecasting: Accurate yield predictability at regional and national levels contributes to better market forecasting, stabilizing food prices, and preventing drastic fluctuation, thereby protecting farmers, businesses and consumers.
• Improved supply-demand management: Accurate yield predictability reduces the need to buffer for seed companies and cuts down on the related wastage. Food Producing Companies can improve inventory management, save space and reduce waste.

The traditional approach to crop yield prediction

While yield prediction holds immense value in bringing the right balance between sustainability & profits for the agricultural sector, its inherent uncertainties due to numerous influencing factors often lead to inaccuracies. Accuracy in yield predictability, regardless of method, depends on the accuracy of observations taken in the field. Data is the core of yield prediction models. The more precise and comprehensive the data, the more robust and trustworthy the predictions.

Traditional yield sampling methods uses a manual random sampling approach. This method relies on historical yield and visual assessments which are then extrapolated to get yield estimates.

It does not account for the heterogeneity of the field, which results in inaccurate sample collection and skewed predictions. Fortunately, the advent of technology, including satellite monitoring, remote sensing, and machine learning tools, is ushering in a new era of more robust and effective prediction models.

Using technology for accurate yield estimation

Satellite monitoring of vegetation indices

Satellites, strategically positioned in orbit, play a pivotal role in assessing both spatial and temporal variations in precision farming practices. Within agriculture, satellite monitoring employs vegetation indices to continually evaluate each farm, analyzing biophysical features in crops. For instance, NDVI interprets crop greenness, indicating plant health, while NDRE determines nitrogen uptake, and LSWI provides insights into water stress. All these play a vital role in determining crop yield.

Remote sensing  for growth variables

Remote sensing, the science of acquiring information without direct physical contact, serves as a powerful tool in agriculture. This data collection tool estimates soil moisture, light received by plants, and more. Remote sensors offer valuable insights into growing crops and their environmental conditions, contributing to accurate crop yield predictions well before the harvest.

Machine learning for improved predictability

Scientists and engineers develop unique machine-learning models to predict yield ranges from farms. Cropin’s Hybrid and advanced yield estimation model integrates data from fields, satellite imagery, remote sensors, and weather data to estimate yield at major crop stages during the cycle. These models are hyper-tuned for different regions, crops, and varieties. Cropin utilizes a hybrid approach encompassing evapotranspiration, crop knowledge graphs, datasets from farming practices, weather, and crop science.

Our approach to crop yield prediction

The Smart Sampling feature offered by Cropin, leverages the above technologies to elevate sample collection to a scientific level surpassing the limitations of traditional approaches.

Smart sampling, a module in Cropin Grow, utilizes advanced indices derived from satellite data to accurately pinpoint and examine diverse areas within a farm, ensuring a truly representative analysis of its heterogeneity. This targeted approach ensures that the data fed into prediction models is of high quality, significantly improving the accuracy and efficacy of yield forecasts.

The feature also allows agronomists to tailor the number of sampling zones to thoroughly analyze and map the inherent farm variability. They can define heterogeneity levels, choose specific zones, set sampling points and then dispatch teams to collect data. The attention to details ensures sample accuracy, capturing the true detail from flourishing to stressed areas, which is crucial to enhance yield predictability.

• Post-Season Analysis: Harvesting Knowledge for Future Growth. Analyze harvested data to refine future yield predictions and strategically plan for the upcoming season, optimizing agricultural practices based on valuable post-harvest insights.

Need for yield re-estimation

Crop yield re-estimation involves adjusting the initial crop yield estimate based on additional data, ensuring a more accurate prediction of the harvest. Reasons for re-estimation include early-season estimates, where unforeseen events impact actual yield. The incorporation of new data inputs collected during the season helps account for these changes and improve the accuracy of yield predictability.

Cropin employs ground-based sampling and remote sensing data, utilizing advanced algorithms trained on historical and current observations to enhance the accuracy of yield re-estimation.
