How Transpiration and Evaporation Shape Global Trends in Evapotranspiration

Evapotranspiration around the world can vary across biomes, and each biome experiences interannual variations. Transpiration contributes more to evapotranspiration in tropical humid regions, and soil evaporation is more prominent in arid and semiarid sparsely vegetated regions. Anthropogenic interventions, such as land-use change and irrigation, can alter evapotranspiration, transpiration, and soil evaporation. Evapotranspiration is a vital… Continue reading…

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‑340 vs Lab Bench Photosynthesis Systems: When Portability Beats Bench Work

Researchers who measure gas exchange often compare the flexibility of a portable photosynthesis system against the precision of a bench-top instrument. Both options have their place in plant physiology, yet the question keeps returning: at what point does portability beat bench work? The Ci-340 Handheld Photosynthesis System sits at the center of this discussion because… Continue reading…

CI‑340 Handheld Photosynthesis System vs LI‑COR 6400XT: A Researcher’s Perspective

Accurate photosynthesis measurement is vital for understanding plant physiology, crop productivity, and responses to stress. Portable gas exchange systems have become essential in both field and controlled studies. Among the leading instruments in this field of photosynthesis measurement systems are CID Bio Science’s CI 340 Handheld Photosynthesis System and LI COR’s LI 6400XT. Both provide… Continue reading…

What Is Crop Coefficient and Is It Essential for Irrigation Efficiency?

To optimize irrigation without excessive water use, the actual water lost through crop evapotranspiration is replaced during watering. The crop coefficient provides information based on crop characteristics that can be used in models for indirect estimation of actual crop evapotranspiration. Crop coefficients are specific for crops, cultivars, regions, local climate, soil, and agricultural management practices.… Continue reading…

How Do Organic Fertilizers and Photosynthetic Rate Work Together?

Most research findings show that organic fertilizers improve the crop’s photosynthetic rate. The improvement occurs through increased photosynthetic efficiency, increased leaf number and area, and enhanced leaf chlorophyll content. Organic fertilizers enhance the soil’s nutrient status to support better plant growth and health, which increases crop photosynthetic rate. In many cases, organic fertilizers were more… Continue reading…

What Are the Causes Behind Global Plant Transpiration Trends?

An increase in the rate of transpiration is observed over approximately 70% of the global land surface. The hike in transpiration over the past four decades is due to greener landscapes. The increase in greenery is attributed to a higher Leaf Area Index, driven by carbon fertilization and higher global temperatures. Lower stomatal conductance, due… Continue reading…

Can Boosting Photosynthesis Efficiency Improve Crop Yields?

Photosynthesis efficiency is very low, averaging 1-3.5% in the fields, and is the next bottleneck for increasing grain production. Photosynthesis has not been a primary target of improvement in crop breeding programs aimed at increasing yields. Scientists estimate that photosynthesis efficiency must be increased by 50% to meet future global food security requirements. The rate… Continue reading…

What Is Transpiration Efficiency and Why Does It Matter for Drought-Resistant Farming?

Transpiration efficiency is emerging as a crucial crop parameter to improve production in water-limited conditions. Restricting transpiration by crops is a vital strategy to increase productivity using less water. External factors like VPD, soil type, and nutrient status are also necessary to increase transpiration efficiency. Society must figure out ways to grow more food for… Continue reading…
