Abstract Microplastic (MP) pollution in terrestrial ecosystems is gaining attention, but there limited research on its effects leafy vegetables when combined with heavy metals. This study examines the impact of three MP types—polyethylene (PE), polyethylene terephthalate (PET), and polystyrene (PS)—at concentrations 0.02, 0.05, 0.1% w/w, along cadmium (Cd) biochar (B), germination, growth, nutrient absorption, metal uptake red amaranth ( Amaranthus tricolor L.). We found that different types did not negatively affect germination parameters like rate, relative vigor, speed. However, they increased phytotoxicity decreased stress tolerance compared to an untreated control (CK1). The presence MPs, particularly PS type, reduced phosphorus potassium while enhancing Cd uptake. For example, treatments 0.02 CdB, 0.05 0.1 CdB content A. seedlings by 158%, 126%, 44%, respectively, treatment (CK2). Additionally, contamination led plant height, leaf dry matter content, fresh weights, indicating adverse growth. Moreover, MPs bioconcentration factors translocation for Cd, suggesting might act as carriers absorption plants. On positive side, addition improved several root parameters, including length, volume, surface area, number tips potential benefits Our shows combination reduces growth increases risk food crops. Further needed understand how various species, which will aid developing targeted mitigation strategies exploring mechanisms through Finally, investigating application conjunction other amendments mitigating these could be key addressing agricultural systems.

Sulfur-Enriched Biochar Soil Amendment Enhances Tolerance to Drought Stress in Faba Bean (Vicia faba L.) Under Saline Soil Conditions

Egyptian Journal of Soil Science, Journal Year: 2025, Volume and Issue: 65(1), P. 0 - 0

Published: Jan. 8, 2025

AGRICULTURAL sustainability and crop yield are seriously threatened by drought stress, especially in areas with limited water resources. In this study, we investigated the potential of sulfur-enriched biochar (S-ACB) as a soil amendment to mitigate negative impacts stress on plants (Vicia faba). Our results revealed that deficit irrigation substantially impaired plant status, photosynthetic efficiency, nutrient acquisition, ultimately resulting decrease growth components. However, incorporation S-ACB into emerged powerful strategy counteract these detrimental effects. played pivotal role enhancing improving facilitating uptake. Notably, positive effects extended beyond mere mitigation, it enabled Vicia faba achieve comparable or even surpassing those well-irrigated plants. Furthermore, application-maintained leaf status reduced Na+/K+ ratio, highlighting its sustain balance under conditions. This study highlights use an efficient long-lasting supplement increase plants' resistance drought. The significant improvements growth, yield, uptake indicate address challenges posed agriculture. These findings offer valuable insights development strategies for sustainable production water-scarce environments, emphasizing importance tool enhance resilience productivity

Identification and Quantification of Microplastics Contamination in Potato from Malang Raya, Indonesia

BIO Web of Conferences, Journal Year: 2024, Volume and Issue: 104, P. 00036 - 00036

Published: Jan. 1, 2024

The presence of microplastics (MPs) in agricultural soil has the potential to contaminate plants and products with negative impacts on humans living creatures. Therefore, identifying quantifying MPs potato farms is essential evaluate. This study aims estimate pollutants farms. found that farm components (potato seedlings, soil, organic fertilizer, potato, irrigation water chips) had a total content 104 particles. higher abundance 2.83 mL –1 was recorded Pujon Kidul lower 0.03 g noted Potato chip – “OK” brand. Considering size microplastic maximum 5.449 mm calculated minimum 0.172 3 rd growing media. colors identified are transparent, black, blue, red, yellow, green. In addition, MP’s shape 68.2 % fibre, 26.9 filament, 3.8 fragment, 1.1 granules components. emerging must be addressed because degradation causes them spread more widely, accumulating over tens hundreds years as hidden danger.

Presence of Microplastics in Water, Soil, Organic Fertilizer, and Potato Plants on Potato Plantations

Environmental Quality Management, Journal Year: 2024, Volume and Issue: 34(2)

Published: Nov. 25, 2024

ABSTRACT Microplastics (MPs) have become a significant environmental concern, but data on their presence in potato gardens are limited. This study aims to identify and quantify MPs soil, organic fertilizer, irrigation water, plants gardens. Soil, samples were collected from fields. Analysis was carried out using microscope Fourier transform infrared spectroscopy (FTIR) the shape, color, quantity, type of MP polymer. The results indicate contamination with most dominant shape fibers (86%) fragments (8%), color black (35%) blue (27%), abundances 0.10–9.20 g −1 , as well polyethylene terephthalate (PET) high‐density (HDPE) polymers. These potential harm plant growth soil quality. found quantities disrupt agricultural ecosystems. can affect quality products human health throughout food chain.
