Agricultural liquid fertilizers12/9/2023 ![]() Organic tomatoes can be cultivated year-round in controlled system greenhouses, but open field production provides easy access for small-scale rural or periurban farms to contribute to the local food system ( Luttikholt 2007 Luttikholt, L. NJAS – Wageningen Journal of Life Sciences, 54, 347-360. Principles of organic agriculture as formulated by the International Federation of Organic Agriculture Movements. Organic cultivation excludes the use of inorganic chemical additives, synthetic fertilizers, insecticides, and herbicides and allows natural resource extraction, improving soil biodiversity and declining hazards to human health ( Luttikholt 2007 Luttikholt, L. Renewable Agricultur., and Food Systems, 22, 86-108. Organic agricultur., and the global food supply. J., Avilés-Vázquez, K., Samulon, A., and Perfecto, I. 2007 Badgley, C., Moghtader, J., Quintero, E., Zakem, E., Chappell, M. This has brought the opportunity for African and Southeast Asian countries to produce organic tomatoes, contributing to an increase in the cultivation and production income ( Badgley et al. Organic tomato production would be expected to offer high premium prices and biodiversity conservation, leading to a more sustainable system ( Luttikholt 2007 Luttikholt, L. However, production has decreased slightly in recent years due to increasing demand for imports of other tropical fruit commodities and concerns of environmental pollution from the intensive application of synthetic chemicals. cerasiforme) production and consumption in the last 20 years has consistently ranked highest in South Korea due to the nutritive value and functional properties of the fruit and use on a variety of ingredients ( Rural Development Administration 2019 Rural Development Administration. Starfish would be the promising LF for use as a supplemental nutrient amendment to increase agroecosystem health, nutrient availability, and fruit productivity.Įarthworms fertigation invertebrate micronutrient pyrosequencing Fruit yield efficiency was improved by the BF treatment, followed by SO and SF among all the treatment. The SF treatment increased fruit fresh weight and fruit yield to 4.2 kg per plant, with similar results observed for BF-treated plants. Seasonal SPAD and PS II values in the leaves were reduced on the FP-plants on 45 and 60 days after fertigation. ![]() ![]() The NT and OC treatments reduced operational taxonomic units and the richness estimator of Chao1 and ACE. ![]() Earthworm biomass was significantly increased by the SF treatment. The number of some invertebrates was increased by the BF and SF treatments. Total amount of total-N supplied was the highest for SF (679 mg The pH in LF ranged between 7.4 and 8.3, and electrical conductivity in the LF was the highest on SF (0.69 dS The LF treatments included bone+fish meal (BF), fish+phosphoric acid (FP), sesame oil (SO), starfish (SF), nontreatment (NT) as control, and oil cake (OC) as an organic fertilizer, fertigating two times per week during the growing season. cerasiforme) experiment conducted in South Korea in the 2019 growing season. This study evaluated the effects of liquid fertilizers (LF) with farm-derived renewable resources on biological activities and chemical attributes of the soil and fruit in an open-field tomato ( Lycopersicon esculentum var. ![]()
