Efficiency and effectiveness of vitamin C-substrate organo-mineral straight fertilizer in lettuce (Lactuca sativa L.)

Abstract

Mineral fertilizers are expensive and last only a relatively short time. Proper handling of fertilizers has a direct impact on crop quality and profitability. Currently, straight fertilizers are divided into types, A and B, based on the fertilizer's sedimentation properties when mixed. Therefore, to solve these flaws, we developed a vitamin C-substrate organomineral fertilizer, AGH-Ringer. This study consisted of a fertilizer equivalency test, which lasted 15 weeks of soil cultivation in a farm field, using lettuce (Lactuca sativa L., ' Jeok Chi Ma') with AGH-Ringer as a test fertilizer. This fertilizer was based on powder compound-type fertilizer r-Ringer and manufactured by chelating essential minerals with a vitamin C substrate to have NPK contents in a ratio of 18.9:14:4.0. In the onsite evaluation, the superiority of AGH-Ringer was demonstrated through an effect of growth stimulation in both aerial and rhizosphere parts of the plants at suitable soil temperatures. This fertilizer also increased yield, even in inadequate low-temperature conditions. In addition, AGHRinger increased the absorption and bioavailability of minerals in lettuce leaves at harvest. The mineral absorption ability showed a uniform pattern during the entire harvest period. It has been confirmed that AGH-Ringer, manufactured with vitamin C as a substrate, is a fertilizer with excellent efficacy that increases growth and harvest simultaneously, solving the existing problems of chemical fertilizers such as sedimentation and lack of mineral absorptivity in nutrient solution systems.

Remediated marine sediment as growing medium for lettuce production: assessment of agronomic performance and food safety in a pilot experiment

“…While the possibility of using reclaimed sediments as growing media in nursery production of ornamental shrubs and trees has been demonstrated, to our knowledge this is the first study assessing the suitability of reclaimed sediments for growing a food crop. As a first approach to this issue, lettuce was chosen among food crops, being a good indicator of the physical and chemical soil/substrate quality . The experiment was intended to be a pilot study aiming at testing the hypothesis that reclaimed sediments could be safely used as ingredients of peat‐free growing media for vegetable plants.…”

Silicic and Ascorbic Acid Induced Modulations in Photosynthetic, Mineral Uptake, and Yield Attributes of Mung Bean (Vigna radiata L. Wilczek) under Ozone Stress

“…This decline in mineral content exists in rice as a result of low solubility of mineral nutrients from the root to the shoot due to reduced transpiration rates and altered membrane transporter activity. In Pb-stressed wheat plants, however, ascorbic acid application increased nutritional contents . These findings may be explained by the direct effects of ascorbic acid application on cell membrane permeability, which facilitate inorganic nutrients to pass through plasma membranes, resulting in an increase in inorganic nutrient transport to metabolically important sites .…”

Adubação Organomineral E Mineral E Resposta Da Soja Em Terras Baixas / Organomineral and Mineral Fertilization and Soybean Response in Lowlands

“…Embora respondam positivamente na produção vegetal, os custos dos fertilizantes minerais são altos (CHAE et al, 2018) e, o estudo de diferentes fontes de fertilizantes visa uma gestão mais eficiente e sustentável da produção agrícola , tornando promissora a utilização de fontes orgânicas (GUIMARÃES et al, 2018). Entretanto, em muitos casos a utilização de fontes orgânicas em áreas extensas não é viável pelo reduzido teor de nutrientes.…”
