Key Findings on CO₂ Enrichment and Greenhouse Crop Nutrition CO₂ enrichment is a cornerstone technology in modern greenhouse horticulture, valued for its ability to boost crop yields, expedite growth cycles, and enhance productivity in controlled environments. Yet, a groundbreaking meta-analysis from Leiden University, published in Global Change Biology, reveals that elevated CO₂ levels directly alter the nutritional makeup of food crops—a critical concern gaining traction for greenhouse growers and controlled-environment agriculture professionals worldwide. Key Findings on CO₂ Enrichment and Greenhouse Crop Nutrition CO₂ enrichment is a cornerstone technology in modern greenhouse horticulture, valued for its ability to boost crop yields, expedite growth cycles, and enhance productivity in controlled environments. Yet, a groundbreaking meta-analysis from Leiden University, published in Global Change Biology, reveals that elevated CO₂ levels directly alter the nutritional makeup of food crops—a critical concern gaining traction for greenhouse growers and controlled-environment agriculture professionals worldwide. Led by Sterre F. ter Haar, Peter M. van Bodegom, and Laura Scherer, this study is the most comprehensive meta-analysis to date on CO₂-induced shifts in crop nutrient content for greenhouse and field applications. It synthesizes data from 109 peer-reviewed studies, encompassing 43 crop varieties and over 29,000 paired observations of edible plant tissues....

In response to frequent snowfall in the Netherlands, major agricultural insurer Hagelunie has issued targeted guidance to local greenhouse growers on greenhouse snow removal—specifically, melting snow accumulated on roof surfaces quickly through internal heating while adjusting greenhouse climate screen positions, and closing the screens only after the roof snow has completely melted and the structure is no longer at risk. This recommendation is rooted in the insurer’s goal of minimizing snow-induced structural damage to greenhouses, which can result in costly repairs and long-term production disruptions. However, it has sparked intense disputes among industry experts, with conflicting views focusing on the delicate trade-off between ensuring greenhouse structural protection and maintaining optimal crop growth conditions during the greenhouse snow melting process. Annemiek Bosma, a senior lecturer at Het Nieuwe Telen (Next Generation Growing), a leading institution in agricultural innovation, acknowledged Hagelunie’s guidance but issued a clear warning about the potential adverse effects of keeping energy screens fully open for prolonged periods. Ton Habraken, a technical expert from renowned climate screen manufacturer Svensson, echoed this concern, adding that fully opening the screen is not a necessary prerequisite for effective greenhouse snow melting, and the greenhouse climate screen position for snow removal should be...

The light-limiting winter months in high latitude countries pose problems for producers trying to produce fresh fruit and vegetables year-round. Supplemental electric lighting is usually required. However, utilizing electric lighting, even high-efficacy LED fixtures, results in high electricity costs. Long photoperiod of low intensity lighting (up to 24 h (hours) is a promising strategy to meet plants’ light requirement (daily light integral (DLI)), which can be implemented in many countries as utility companies incentivize the use of low-cost, off-peak electricity use. In this study, researchers compared a conventional 16 h white light treatment (Control) to a 24 h treatment which involved a change from white light during the day to blue light at night at a reduced photosynthetic photon flux density (PPFD; dynamic) and a static light treatment which kept both spectrum and PPFD constant for 24 h on 2 cherry tomato cultivars. In addition, each treatment also had a low blue (10%) and high blue (30%) variation. All treatments had the same DLI. It was found that the 24 h dynamic lighting strategies had similar maximum quantum yield of photosystem II (Fv/Fm) as the 16 h controls while that at 24 h static treatments were drastically reduced. In addition,...
