“…The practice of horticulture in urban areas is increasing, as it provides locally produced fresh products [4,5]. It has several advantages, such as being able to cultivate fresh food anywhere, including on window ledges and balconies; in greenhouses and vertical farms; and on green roofs and other modern infrastructure [6].…”

Effects of LED Lights and New Long-Term-Release Fertilizers on Lettuce Growth: A Contribution for Sustainable Horticulture

et al. 2023

The horticulture sector has been directed by European guidelines to improve its practices related to environmental sustainability. Moreover, the practice of horticulture in urban areas is increasing since it provides fresh products that are locally produced. At the same time, horticulture needs to implement circular economy approaches and energy-efficient models. Therefore, to address these issues, this study investigated the effects of an integrated fertilizer-box-based cultivation system equipped with LED lights and coated porous inorganic materials (C-PIMs), which was applied as fertilizer, on Lactuca sativa L. growth. Two different types of lightweight aggregates were formulated considering agri-food and post-consumer waste, and they were enriched with potassium and phosphorus. Involving waste in the process was part of their valorization in the circular economy. Using PIMs as fertilizers enabled the controlled release of nutrients over time. The tests were carried out in controlled conditions using two LED lighting systems capable of changing their light spectrum according to the growth phases of the plants. The effects of two different lighting schemes on the growth of lettuce plants, in combination with different amounts of aggregates, were studied. The results showed that increasing the amount of C-PIMs statistically improved the lettuce growth in terms of dry biomass production (+60% and +34% for two different types of PIM application) when the plants were exposed to the first LED scheme (LED-1). Plant height and leaf areas significantly increased when exposed to the second LED scheme (LED-2), in combination with the presence of C-PIMs in the soil. The analysis of the heavy metal contents in the lettuce leaves and the soil at the end of the test revealed that these elements remained significantly below the legislated thresholds. The experimental achievements of this study identified a new approach to improve the environmental sustainability of horticulture, especially in an urban/domestic context.

“…Overall, via encouraging environmental sustainability and enhancing public health outcomes, it can aid in addressing the complicated problem of global food insecurity. Furthermore, by giving importance to soil health, biodiversity, and ecosystem resilience, regenerative agriculture techniques like crop rotation and community-supported agriculture may promote sustainable food production systems (Congreves, 2022b) (McCauley, 2021) (Urban Horticulture for Food Security, n.d.).…”

When it comes to solving the interconnected problems of global nutrition and food security, horticulture is essential. Horticulture provides sustainable ways to increase food production while encouraging a varied and nutrient-rich diet in light of the world's expanding population and mounting demand on agricultural resources. Horticulture improves dietary diversity and fights malnutrition by increasing the availability of nutrient-dense food through the production of fruits, vegetables, herbs, and decorative plants. Horticulture's adaptation to many climatic circumstances is one of its main advantages. Horticultural approaches, which range from big commercial farms to little backyard gardens, may be customized to fit local conditions, enabling communities to grow their own food and lowering their need on imported items. In addition to improving food security, this decentralization of food production increases resilience against outside shocks like market volatility and climate change. Horticulture provides a wide variety of nutrient-dense crops that are necessary for a balanced diet, which helps to solve the problems associated with global nutrition. Antioxidants, vitamins, and minerals found in abundance in fruits and vegetables are essential for avoiding chronic illnesses and micronutrient shortages. Furthermore, horticulture commodities may be turned into value-added goods like jams, juices, and dried fruits, which will increase their year-round accessibility and shelf life.
