Purpose: assessment of the use photosynthetically active radiation (PAR) by soybeans while using improved cultivation technology on irrigated lands in Rostov region. Materials and methods. The studies were carried out at Bessergenevskoe Agricultural Enterprise LLC 2019–2021. laying field experiments soybean crops, recording observations according to methods VNIIMK All-Union Scientific Research ...

The three-dimensional (3-D) spatiotemporal distribution of forest canopy photosynthetically active radiation (PAR) is a major determinant within-crown variations leaf photosynthesis and transpiration. However, it remains challenging to map the 3-D PAR within under due limited ability capture detailed structures canopies.This study proposes simple approach estimate at fine spatial resolution bas...

Photosynthetically active radiation (PAR) is the 400–700 nm portion of solar spectrum that photoautotrophic organisms including plants, algae, and cyanobacteria use for photosynthesis. PAR a key variable in global ecosystem Earth system modeling, playing prominent role carbon water cycling. Alongside air temperature, availability, atmospheric CO2 concentration, controls photosynthesis consequen...
