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

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 larg···

Soil nutrient rapid tester breaks through agricultural testing bottleneck

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 co···

How to balance accuracy, speed and repeatability in chlorophyll meter

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 lea···

Chlorophyll fluorescence spectrometer: a non-destructive probe for decoding the health of plant photosynthetic systems

Obtain the rapid fluorescence kinetic curve of OJIP (0.1–10 s).The basic parameters measured are: Fo, Fj, Fi, Fm (Fp).

Soil rapid testing instruments usher in a new era of rapid diagnosis in precision agriculture.

soil rapid testing condenses the complex laboratory analysis process into a portable device, enabling on-site, rapid, and accurate diagnosis of key soil indicators, becoming a pioneering tool for promoting precision and intelligence in agriculture.

Breakthrough and Application of High-Precision Photographic Plant Root System Analyzer

The photo-based plant root analysis system is designed for rapid, multi-parameter, and batch automated analysis of cleaned roots with a diameter of 0.5 mm or more. The entire system consists of a document scanner, analysis software (PC-based), and a computer (self-provided). Its ···
