How Algae Produce Oxygen Algae, like land plants, contain chloroplasts with chlorophyll pigments that absorb sunlight. Chloroplasts are found within plant cells and algal cells, and are responsible for photosynthesis. Algae, like green plants, use chlorophyll to capture sunlight and produce oxygen. During daylight hours, these microorganisms transform carbon dioxide and water into glucose for ...
The ThirdEye project supports farmers in Mozambique and Kenya with their decision making in farm and crop management by setting up a network of flying sensors operators. Our innovation is a major transformation in farmers’ decision making regarding the application of limited resources such as water, seeds, fertilizer and labor. Instead of relying on common-sense management, farmers are now ...
Summary: In the study of plant physiology, the determination of plant photosynthesis is one of the important research work. It is generally measured by measuring the value of illuminance and photosynthetically active radiation, and the measurement of illuminance and photosynthetically active radiation requires a light sensor and ...
In the new study, the research team shows how this region works in concert with other structures within the cell to activate the production of "wartime" proteins. The research shows that when plants detect pathogen attack, molecular markers that normally instruct ribosomes to land and read mRNA are removed, which prevents cells from making their typical "peacetime" proteins. ...
The photosynthetically active radiation sensor adopts the photoelectric sensing principle and can be used to measure the photosynthetically active radiation in the spectral range of 400~700nm. ...
Though they can tolerate wide ranges of temperatures, oysters are sensitive to variables such as salinity and dissolved oxygen. Photosynthesis (PAR) of plants and algae in the water are responsible for much of the water’s dissolved oxygen and are crucial to the survival of oysters. ...
The photosynthetically active radiation sensor adopts the photoelectric sensing principle and can be used to measure the photosynthetically active radiation in the spectral range of 400~700nm. ...
Abstract : Land Surface Phenology (LSP) and Leaf Area Index (LAI) are important variables that describe the photosynthetically active phase and capacity of vegetation. Both are derived on the global scale from optical satellite sensors and require robust validation based on in situ sensors at high temporal resolution. This study assesses the PAI Autonomous System from Transmittance Sensors at 57 ...

Thousand kernel weight (TKW) is a yield component, and protein rate is a price component. Both are important parameters to farmers and depend on photosynthetical activity as well as nitrogen availability. Up to 50% of photosynthetical activity of wheat is due to the flag ...
Whether you’re a grower wanting to extend your season in the hoop house or greenhouse, an urban rooftop farm, or a small indoor start-up—horticultural lighting gives you the flexibility and assurance that you will be growing the highest quality products year-round. With demand for local grown produce increasing, it’s not surprising to see many small growers expand into ...
In applied photosynthesis research, the three most c o m m o n l y used units of light and radiation measurement are: (1) the illumination in lux or footcandles (flux of lumens, the photometric unit based on the brightness response of the eye); Original AbstractABSTRACT McC’~E, K. ...
Lighting for commercial hemp production – 5 tips on how to light your hemp crop for maximum yields, quality and potency. We know that light is essential for plant growth, and for a plant such as hemp, which is adapted to high light levels, and where yields and quality are heavily influenced by light intensity – having supplemental or a high-quality sole source lighting systems is ...
What is the difference between Red/Blue vs. Broad “Full” Spectrum LEDs? Growers generally have two options when it comes to horticultural LED spectrums – “full spectrum” or “broad-spectrum”, which appears as white light; and “red/blue spectrum”, which can appear as purple or pink light. The red/blue spectrum LED luminaires are often referred ...
Weather trends can cause variation in photosynthetic activity of subaquatic plant life, resulting in an imbalance which depletes dissolved oxygen (DO) levels. ...
Irrigation is essential to increase food production. However, competing needs and increasing drought makes water for irrigation scarce. Therefore, new methods and strategies are continuously being tested by scientists to improve food production, accompanied by better water use efficiency. This article will examine how modern field tools are helping in this venture. Irrigation Methods According ...
With the pressure to increase food production, every agricultural practice that can be optimized for improving crop yield is under scrutiny; therefore, micronutrients, which are important for crop health and growth, are receiving more attention. Agronomists are increasingly studying different treatment methods to establish the easiest and most cost-effective way to improve micronutrient ...
According to a review by Dr. Crocombe, hand-held spectrometers have historically been used by only small groups of people, such as analytical and drug companies. These days, spectroscopy is available in simple low cost devices for a multitude of applications for scientists and non-scientists alike. One of the most prominent uses of spectroscopy has been the use of the technology on leaves for ...
In the autumn of 2013, Nicholas Bond, who was then the State Climatologist for the state of Washington, first detected a large (500 miles wide x 300 feet deep), circular body of sea water which had not cooled as expected and was 2 to 3 degrees warmer than the rest of the surrounding Pacific Ocean. By mid-2014, this unnaturally warm patch of ocean had grown to 100 miles long x 1000 miles wide x ...
Farm Fertilizer - A Double-Edged Sword The excessive use of fertilizers is one of the main causes of the environmental impact of industrial agriculture. The notion that more is better has caused more harm than good to farming, as well as the environment. Therefore, using the right amount of fertilizers is considered an important part of farm management. To this end, there has been a lot of ...
If you are looking for a classic example of the circle of life, consider the forest canopy structure. A forest’s canopy structure is influenced by environmental and soil factors, and it also influences these factors in return. It is an aspect of forest ecology that is receiving more attention in this age of climate change emergency. The canopy structure is often overlooked, with most of the ...
