Ground-based canopy reflectance sensing for variable-rate nitrogen corn fertilization
Nitrogen available to support corn (Zea mays L.) production can be highly variable within fields. Canopy reflectance sensing for assessing crop N health has been proposed as a technology to base side-dress variable-rate N application. Objectives of this research were to evaluate the use of active-light crop-canopy reflectance sensors for assessing corn N need, and derive the N fertilizer rate ...

Light Uniformity - Comparing LED and HPS Luminaires
Light uniformity is an important factor when it comes to growing a consistent crop and optimizing your growing environment, however, there has been some misinformation about the way HID and LED luminaires distribute light and affect plant health. As a manufacturer of both HID and LED technology, P.L. Light Systems always strives to show the complete picture of both technologies. We think both ...

Variation in photosynthetic photon flux density within a tropical seasonal rain forest of Xishuangbanna, south-western China
The effects of canopy development, solar angle, and weather conditions on temporal variation in photosynthetic photon flux density (PPFD) at three heights within a tropical rain forest canopy in Xishuangbanna, China, were examined. PPFD was measured every second and stored as 10-min averages from 1 December 2002 to 30 November 2003. PPFD variability was examined at three different tempcral ...

Leaf area - How & why measuring leaf area is vital to plant research
It is easy to measure leaves, and they are also the parts of a plant most responsive to their environment. The combination of these two factors makes leaf area measurement extremely useful to scientists and growers. Besides, leaves are one of the main plant organs and are responsible for the productivity of a plant, and on a larger scale, of an ecosystem or a farm. Therefore, an understanding of ...

Parking Lot Hail Protection
It is amazing the number of different options that have been created to try to alleviate the problems associated with massive chunks of ice falling out of the sky. Hail can cause a lot of damage and super expensive damage at that. We recognized this at WeatherSolve a number of years ago and started to work on developing a system to fix this issue. WeatherSolve already had a whole lot of ...

The Importance of Leaf Area Index (LAI) in Environmental and Crop Research
Leaf Area Index (LAI), which is used as a measure in hundreds of studies on forests, crops, climate and the environment, is calculated as half the area of all leaves per unit area of ground. It is measured as the leaf area (m2 ) per ground area (m–2) and is unit-less. So, a plant with a LAI of 2 has an amount of leaves that can cover a given area two times. LAI is calculated for a plant or ...

LED or HPS for Growing Cannabis?
“What lighting source should I use for my licensed cannabis grow?”; “I am comparing LED to HPS for my cannabis operation. Which source do you recommend?” These are questions people ask me almost on a daily basis. We have covered this question in past posts on our blog, like this one by our very own head of marketing: LEDs vs Traditional Lighting but most cannabis growers ...
