“…The results for the net photosynthetic rate (A N ) did not show significant differences for either crop; this could be a result of the addition of N‐fertilizers inhibiting photosynthesis above a certain threshold 49 . If we focus on organic farming, the results of A N , together with stomatal conductance (gs), which was higher in conventionally grown trees, similar to the findings in an organic soybean crop, 55 suggest that organic farming improves WUEi in plants. This could be related to the functionality of aquaporins because plants decrease their transport of water as a result of a decrease in the functionality of aquaporins with respect to the lower N content in organic farming 56 .…”

BackgroundRecently, vesicles derived from plant cell membranes received attention for their potential use as active biomolecules and nanocarriers, and obtaining them from organic crops may be an interesting option, as different farming systems can affect production, plant secondary metabolism, and biochemistry of cell membranes. This study aims to determine how organic and conventional farming affect the mineral nutrition, gas exchange, CO2 fixation, and biochemical composition of lemon fruits, which could have an impact on the different fractions of cell membranes in pulp and juice.ResultsThe results showed that organic trees had higher intrinsic water use efficiency (WUEi) but conventional trees had higher stomatal conductance (gs) and nitrogen use efficiency (NUtE). Also, organic lemons had significantly higher levels of some micronutrients (Ca, Cu, Fe, and Zn). Secondly, the main differences in the membrane vesicles showed that organic pulp vesicles had a higher antioxidant activity and more oleic acid, while both types of vesicles from conventional lemons had more linoleic acid.ConclusionsIn conclusion, organic farming did not alter carbon fixation parameters but impacted nitrogen fixation and water uptake, and resulted in higher micronutrient levels in lemons. These mineral nutritional changes could be related to the higher production of membranes that showed suitable morphological traits and a high antioxidant activity, positively correlated with a high amount of oleic acid, which could have stronger cell protection characteristics.This article is protected by copyright.

“…Conventional Agricultural practices incur substantial environmental costs, encompassing soil degradation, freshwater contamination, eutrophication, and loss of biodiversity and habitats [102]. In response to these challenges, organic agriculture has emerged as a touted sustainable alternative, characterized by lower environmental impacts compared to conventional highinput agriculture [68,76,85,106,107]. Extensive research indicates that organic farming not only mitigates these environmental costs but also holds potential benefits for soil health.…”

“…Several studies have compared organic and conventional systems and have found that organic systems have lower yields, depending on the crop type and agroecological condition [106,107]. The issue of lower yields in organic farming may be caused by many factors, such as the type of seed used, the environmental conditions of the plants, and many more.…”

Organic horticulture is a holistic management system that follows good production practices and should be considered the cornerstone of mitigating climate change and producing healthier fruits and vegetables. This agroecosystem practice not only benefits the green economy but promotes and enhances soil biological activity, biodiversity, and other biological cycles in the sphere. The last decade has observed a rise in the production and consumption of organically certified agricultural products, and the biggest growth was registered in France (18%) due to its higher nutritional value of vitamin C (27%) and polyphenol content (72%), with a lowered risk of exposure to harmful chemicals of up to 70% and improved organoleptic properties. Between 2012 and 2020, the European Union’s organic sector experienced significant growth, with a 56% expansion in organic land area, a 40% increase in organic producers, and a 114% increase in retail sales. The aim of this review was to evaluate the significant impact of organic horticulture on mitigating climate change and meeting consumer needs by examining key research areas, including Soil Health and Management, Pest and Disease Management, Climate Resilience and Adaptation, Carbon Sequestration and Climate Mitigation, Market and Consumer Preferences, and Policy and Institutional Support. The outcome of this review demonstrates that there are still numerous research studies required to evaluate how different farming systems and pedoclimatic conditions can contribute to more efficient horticultural practices.

“…For instance, there was one report that minimal tillage (MT) and no tillage (NT) techniques significantly reduced SOM loss by 17% and 63%, respectively, compared to traditional tillage [15]. Furthermore, in soybean growing areas in Europe, low-input organic agriculture enhanced the SOM content of farmland compared to traditional mechanization and maintained sustainable agricultural development [16]. Therefore, it can be said that agricultural mechanization has a very complex impact on the SOM of farmland, while the process of rural urbanization has a profound impact.…”

Studying the impact of urbanization on changes in the soil organic matter (SOM) content of farmland plays an important role in determining the influence mechanism of urbanization regarding regional environmental change. Taking the farmland in Yushu City, northeast China, as the research area, in May 2019, 68,393 sample plots (each plot: 60 m × 60 m) were set up in farmland and sampled to measure the SOM content of each plot while combining image data from the same period in the study area (resolution: 60 m). This investigation was based on 17 levels divided by the size of areas occupied by residences, using residential areas as the center and a radius of 60 m. Through a gradually buffered extrapolation method combined with mathematical functions, the influence of rural urbanization on the changes in SOM content was revealed. These results showed that the slope of the linear function between the SOM content and the residential area level was greater than zero and that with the continuous advancement of urbanization, the SOM content had an increasing trend. When urbanization advanced to the stage of larger cities, large-scale mechanized production led to land degradation. When urbanization advanced to the stage of towns, intensive cultivation was beneficial for land restoration. The findings of this study provide a reference basis for future studies of the relationship between rural urbanization and agricultural mechanization around the world.
