Learning Parametric Nitrogen Fertilizer Response Curves Using Neuro Symbolic Regression

arXiv:2605.31276v1 Announce Type: new Abstract: Accurately modeling crop response to Nitrogen (N) fertilization is a fundamental challenge in precision agriculture, as it impacts both economic returns and environmental sustainability. Existing approaches either rely on predefined parametric forms or opaque machine learning models, limiting their ability to interpret or discover site-specific functional relationships from data. In this work, we propose a neuro symbolic regression (SR) approach to learn parametric N-response curves without assuming a predefined functional form. Our approach inte

Why this matters
Why now

Advances in neuro-symbolic regression are enabling more interpretable and adaptable AI models, specifically in domains like precision agriculture where nuanced functional relationships are critical.

Why it’s important

This development allows for data-driven, site-specific optimization of agricultural inputs, directly impacting economic efficiency and environmental sustainability for a critical sector.

What changes

Farmers and agricultural scientists can now use AI to discover optimal nitrogen fertilization strategies without relying on pre-defined models, leading to more precise and less wasteful practices.
