Engineering Implementation of a Closed-Loop System for Soil Nutrient Testing and Fertilizer Recommendation

Engineering Implementation of a Closed-Loop System for Soil Nutrient Testing and Fertilizer Recommendation

2026-04-14

In the current agricultural input market environment, as a frontline sales manager, I deeply feel that the industry is undergoing a profound transformation. In the past, we could dominate the market by relying on channel pushes and price advantages. However, with the rise of large-scale farmers and the advancement of national policies to reduce fertilizer use and increase efficiency, the market's demand for professional services is increasingly urgent. Traditional agricultural input sales models are facing severe challenges; simply "selling products" is no longer sufficient to maintain customer loyalty. "Selling services and solutions" has become the new industry consensus. However, in promoting technical services, many colleagues face the same pain points: soil and fertilizer testing relies on laboratories, which is time-consuming and costly, failing to meet the needs of immediate decision-making in the fields; even with data, there is a lack of effective conversion tools, making it difficult to formulate precise fertilization plans. These bottlenecks severely restrict the efficiency of business expansion. Today, I would like to discuss with you, from a market application perspective, how to break this deadlock through technological means and redefine the value chain of agricultural input services.

From a research and development perspective, a common misconception in soil testing is equating "being able to measure values" with "being able to guide production." In reality, what agricultural fields truly need is not a series of isolated test results, but rather actionable conclusions that can be mapped to fertilization decisions, plot management, and target yield control. Many devices can output data on soil ammonium nitrogen, available phosphorus, and available potassium at the experimental level, but once applied in the field, the data often faces difficulties in comparison, reuse, and traceability. The root of the problem lies not in the testing process itself, but in the lack of an algorithmic coupling layer that connects nutrient data, crop needs, and management objectives.

Based on the chlorophyll spectrum absorption law, the chlorophyll meter uses two different light-emitting tubes to illuminate the leaves. By measuring the intensity of the light transmitted through the leaves, it calculates the relative chlorophyll content or greenness of the leaves, thus providing a reliable scientific basis for rational, appropriate and timely fertilization. It is widely used in scientific research and production guidance in agriculture, forestry and botany.
