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 photosynthetically active radiation ...
There are usually two types of sensors used to measure the light in a greenhouse: (1) global radiation, usually called energy units, and (2) photosynthetically active radiation (PAR). ...
High frequency data was collected between January and March of 2019 using the PME miniDOT® for dissolved oxygen and temperature, the miniPAR for photosynthetically active radiation and the HOBO brand conductivity sensor to measure salinity. ...

2020 was a record year for strawberry yields at the Water Efficient Technology Centre (WET Centre), based at NIAB EMR in Kent, UK. The WET Centre is an extensive research and demonstration facility that features a portfolio of innovative growing techniques and smart irrigation systems for the soft fruit sector. It showcases the latest solutions to improve water use efficiency and local water ...
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 ...
Spectral quantum yields The aim of these measurements is to provide a factual basis for a standard definition o f “photosynthetically active radiation”. The need for a standard definition has been repeatedly emphasized (e.g., GABRIELSEN, 1940; RABINOWlTCH, 1951, pp.837-844; MCCREE, 1966), but so far, no one definition has been ...
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 ...
This coating reduces the efficiency of the LED in converting photons into usable PAR (photosynthetically active radiation) light, but makes for a better work environment in sole source applications. ...
With irrigation being used in many spheres of life and food production methods getting diversified, it is not surprising that research on this topic is getting more specialized. Procedures for analysis, which were restricted earlier to big institutions, need to be widely available so that their reach is extended and science will benefit from more in-depth studies. An increasing number of ...
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 ...
The portion of visible light spectrum between 400-700 nm is vital for photosynthesis and is called the photosynthetically active radiation. When there is more solar radiation, ambient and soil temperature will rise. ...
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 ...
The miniPAR logger measures photosynthetically active radiation, also known as diffused sunlight. The MSCTI measures conductivity, which can help establish salinity levels. ...
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 ...
It can be used for estimating canopy cover, light transmittance, leaf area index and photosynthetically active radiation. It is suitable for tree level measurements of crown architecture and dimensions, and density. ...
It is one of the most important parameters to measure leaves and their activity. Why is LAI important? The significance of the LAI comes from the importance of leaves to the plants, which are many and varied. ...
