Disinfestation of recirculating nutrient solutions in greenhouse horticulture

Agronomie, 2001
Recirculating nutrient systems offer a good method to control nutrient leaching from greenhouses into the environment. However, the potential for the rapid spread of root diseases is the main hindrance to adoption of recirculating nutrient systems by the greenhouse industry.

LED lighting in greenhouse horticulture : Photosynthesis

, 2022
Light spectrum has a significant impact on a wide variety of plant processes including photosynthesis and photomorphogenesis which in turn impact plant productivity. The choice of supplementary light spectrum in greenhouses is therefore not trivial, and this is especially so given the diverse spectral possibilities afforded by increasingly popular LED ...

Modelling Crop Transpiration in Greenhouses: Different Models for Different Applications

Agronomy, 2019
Models for the evapotranspiration of greenhouse crops are needed both for accurate irrigation and for the simulation or management of the greenhouse climate. For this purpose, several evapotranspiration models have been developed and presented, all based
