“…Fruits and vegetables contain vitamin, minerals, electrolytes, dietary fiber, and phytochemicals especially antioxidants. Although the positive aspects of consumption of fruits and vegetables are promoted, vegetables especially leafy green vegetables are concentrated in nitrates that have been linked to adverse health effects especially in children (Karnpanit et al, 2018). Production practices that increase the nutrient content of vegetables while limiting high amounts of potential negative compounds such as nitrates are of interest.…”

“…Nitrate is a chemical substance naturally found in plants and heavy use of chemical fertilizers, especially nitrogen to increase crop yield increases nitrate levels in plants (Karnpanit et al, 2018). Many vegetables, especially green leafy vegetables contain high amounts of nitrate (Leon and Luzardo, 2020).…”

“…Nitrate accumulation is common in Brassica plants as well as other leafy vegetables such as spinach and lettuce and is influenced heavily by nitrogen fertilization practices (Hamdard et al, 2009). Cultivation practices are known to affect nitrate levels in vegetables (Karnpanit et al, 2018). Nitrate contents of most leafy vegetable grown under organic and and GAP (good agricultural practice) cultivation in Thailand were lower than those grown with conventional production (Karnpanit et al, 2018).…”

Arugula (Eruca sativa), mizuna (Brassica rapa var. nipponsinca), red giant mustard (Brassica juncea), and spinach (Spinaciaoleracea “Tyee”) are fresh produce crops high in nutritive value that provide shortfall and high interest nutrients addressed in the U.S. Dietary Guidelines. The primary objective of this project was to evaluate fertility treatments unique to these crops that optimize their nutritional capacity. Measurements discussed include: vitamin C, dietary fiber, calcium, iron, potassium, sodium, and nitrate. Plants were grown at the University of Minnesota St. Paul Campus (St. Paul, MN) in a greenhouse from November to April under an 18 h photoperiod and a 24/13°C day/night temperature. Plants were grown using five different fertility treatments, including four organic treatments and one conventional control. The plant treatment combinations were replicated three times and the entire experiment was duplicated. Fertility treatments had a high impact on vitamin C (with over a 3-fold difference in treatments in the first experiment), nitrate (over 10-fold difference among fertility treatments in some species) and potassium concentrations (over 5-fold difference among fertility treatments in some species) in analyzed plant tissue. No consistent differences were found for fiber, calcium, iron and sodium concentrations in tissue analyzed. This is the first study to analyze the impact that different organic treatments can have on multiple nutrients and compounds addressed by the U.S. Dietary Guidelines for high-impact, highly-consumed produce crops.

Nitrogen Interactions Cause Soil Degradation in Greenhouses: Their Relationship to Soil Preservation in China

et al. 2023

View full text Add to dashboard Cite

Proper greenhouse fertilization is crucial for establishing high-quality yields, particularly as food demand grows. In this review, the effect of fertilizers, specifically nitrogen, on greenhouses and degradation caused by nitrogen interactions are critically evaluated based on a literature analysis. Nitrogen (N) fertilizers, which represent reactive or biologically accessible nitrogen in soil, are currently used in agricultural systems. Soil, water, and air are endangered by reactive nitrogen pollution. Increasing food demand causes a rise in N fertilizer use, which harms the environment and living organisms. In developing countries, more N is used per capita than in underdeveloped countries. Greenhouse agriculture accounts for 3.6% of total agricultural production. It was revealed that greenhouses in China often get 13–17 times as much nitrogen fertilizer as traditional farming. N was overused abundantly throughout the year, which led to soil acidity, nutritional imbalance, and secondary salinization. Studies on soil salinization and secondary salinization in China date back 70 years. This review attempts to draw attention to the soil damage in greenhouses caused by excessive nitrogen. Nitrate leaching and soil acidity received special attention in this review. Numerous eco-friendly techniques for avoiding soil degradation brought on by the execessive use of fertilizer are also discussed.
