Chlorophyll Fluorescence for Non-Destructive Estimation of Crop Nutrient Status
Chlorophyll fluorescence (ChF) can detect individual and multiple nutrient deficiencies simultaneously. The method involves non-destructive, precise, real-time measurements. A species-specific approach is necessary when developing ChF-based technology to detect multiple nutrient deficiencies. The main aim of agricultural practices is to optimize conditions and resources essential to maintaining productivity. Instead of determining the levels of a… Continue reading…
How Light Fluorescence Ratios Help Detect Plant Stress Before Symptoms Appear
Plant leaves fluoresce red, far-red, blue, and green under varying wavelengths of light. Chlorophyll fluorescence-based ratios include Fv/Fm and the red-to-far-red ratio. Fluorescence from red, far-red, blue, and green light occurs in response to UV light. Blue-to-red and blue-to-far-red ratios are more sensitive to stress than the chlorophyll fluorescence ratio of red/far-red. Plants do not… Continue reading…
CI‑110 vs Smartphone Fish‑Eye Canopy Solutions: Can cheap compete?
Researchers talk a lot about quick canopy imaging tricks lately, especially when phone apps promise convenience. Those tools attract interest because they cost almost nothing and sit in every pocket. Still, when you compare them to a true plant canopy imager, the differences grow obvious fast. The CI-110 sits in a class of its own… Continue reading…
How to Choose a Canopy Analyzer: What to Look For in 2025
Choosing a canopy analyzer in 2025 is not as straightforward as picking the newest device on the market. Plant scientists, ecologists, foresters and agronomists rely on these instruments to quantify canopy structure, estimate LAI, evaluate light environments and understand how vegetation interacts with the atmosphere. Because the canopy analyzer plays such a central role in… Continue reading…
Buyer Checklist: Root Imagers for Crop‑Rhizosphere Research
Selecting the right root imagers for crop rhizosphere research is a practical decision that often determines the quality and reliability of underground data. Roots change constantly as they respond to water, nutrients, texture, biota, and management. Capturing these responses in situ requires imaging systems that are stable, portable, and able to deliver clear, repeatable scans… Continue reading…
Using the CI‑340 Handheld Photosynthesis System for Drought Stress Trials in Wheat
Drought stress trials in wheat often come down to one core question: how efficiently is the plant still exchanging gas as water becomes limiting? The CI-340 Handheld Photosynthesis System is designed for exactly this type of work. In field plots, greenhouses, and controlled environments, the CI-340 Handheld Photosynthesis System gives researchers direct access to photosynthesis,… Continue reading…
How Does the Red-to-Far-Red Fluorescence Ratio Reveal Plant Stress?
The red-to-far-red fluorescence ratio is sensitive to changes in environmental and growing conditions; therefore, it can be used as an early indicator of plant stress. Photosynthesis, especially the sensitivity of photosystem II (PS II) to stress, is leveraged while using the ratio. The red-to-far-red ratio has several practical applications in precision agriculture and in developing… Continue reading…
CI‑110 Plant Canopy Imager vs Drone‑Based LAI Measurements: Which gives you more for your money?
A plant canopy imager has become a core tool for crop scientists who want quick, reliable leaf area index (LAI) measurements in the field. Many research teams now debate whether handheld canopy instruments or drone-based LAI models offer better value. Both approaches collect important canopy structure data, but they differ in cost, accuracy, workflow, and… Continue reading…
CI‑110 vs LAI‑2200C: Can CID’s System Outperform a Hemispherical Camera Approach?
When it comes to understanding canopy structure and light distribution, precision matters. Researchers in forestry, agronomy, and ecology depend on accurate Leaf Area Index (LAI) data to model photosynthesis, evaluate growth, and manage ecosystems. Traditionally, devices like the LAI-2200C from LI-COR have dominated this space with hemispherical sensor arrays. CID Bio-Science’s CI-110 Plant Canopy Imager… Continue reading…
Root Structure and Function Gradients in Salt Marshes
Salt marshes are unique ecosystems characterized by micro-heterogeneity in elevation, soil, tidal inundation, salinity, and oxygen availability. In these extreme conditions, plants are adapted to each zone, so root traits also vary. Root biomass, density, tissue type, and size of roots are adapted for each of the three prominent zones in salt marshes. Salt marshes… Continue reading…
