From Flourish to Nourish: Cultivating Soil Health for Sustainable Floriculture
AI summary Read the abstract
This review examines the sustainability challenges facing the floriculture industry, focusing on soil health threats from fertilizer-driven acidification, pesticide residues, and plastic debris accumulation from excessive plastic use in cultivation. The authors propose sustainable practices including stress-resistant cultivar breeding, soil health-focused management, and plastic recycling to address declining soil quality and support a more sustainable ornamental flower industry.
Despite its rapid growth and economic success, the sustainability of the floriculture industry as it is presently conducted is debatable, due to the huge environmental impacts it initiates and incurs. Achieving sustainability requires joint efforts from all stakeholders, a fact that is often neglected in discussions that frequently focus upon economically driven management concerns. This review attempts to raise awareness and collective responsibility among the key practitioners in floriculture by discussing its sustainability in the context of soil health, as soil is the foundation of agriculture systems. Major challenges posed to soil health arise from soil acidification and salinization stimulated by the abusive use of fertilizers. The poisoning of soil biota by pesticide residues and plastic debris due to the excessive application of pesticides and disposal of plastics is another significant issue and concern. The consequence of continuous cropping obstacles are further elucidated by the concept of plant-soil feedback. Based on these challenges, we propose the adoption and implementation of several sustainable practices including breeding stress-resistant and nutrient-efficient cultivars, making sustainable soil management a goal of floriculture production, and the recycling of plastics to overcome and mitigate the decline in soil health. The problems created by flower waste materials are highlighted and efficient treatment by biochar synthesis is suggested. We acknowledge the complexity of developing and implementing the proposed practices in floriculture as there is limited collaboration among the research and operational communities, and the policymakers. Additional research examining the impacts the floriculture industry has upon soils is needed to develop more sustainable production practices that can help resolve the current threats and to bridge the understanding gap between researchers and stakeholders in floriculture.

Understanding the impact of microplastic contamination on soil quality and eco-toxicological risks in horticulture: A comprehensive review
AI summary Read the abstract
This review examines how microplastic contamination in horticultural soils affects soil quality, plant health, and food safety. Microplastics alter soil structure, reduce beneficial microbial activity, and can transfer toxic chemicals to edible crops. Since horticulture provides a significant portion of the global food supply, understanding and addressing microplastic contamination in these soils is critical for protecting human health.
The Hidden Threat: How Plastic Pollution Is Affecting Soil Fertility
AI summary Read the abstract
Researchers reviewed how plastic fragmentation in agricultural soils — driven by UV exposure, plowing, wind, and water — produces microplastics that enter plant root systems and the food chain, with evidence that both biotic transport through invertebrates and abiotic mechanisms distribute particles throughout the soil ecosystem.
Soil under stress: The importance of soil life and how it is influenced by (micro)plastic pollution
AI summary Read the abstract
This review examines how plastic pollution in soil disrupts soil organisms and microorganisms that regulate essential ecosystem functions, finding that plastic alters soil chemistry, physical structure, and microbial communities in ways that threaten primary production and carbon cycling.
Impact of the sustainable agricultural practices for governing soil health from the perspective of a rising agri-based circular bioeconomy
AI summary Read the abstract
This review examines sustainable farming practices for maintaining soil health and supporting a circular bioeconomy, focusing on preserving soil organic matter as the foundation of productive agriculture. Depleted soils are a growing global concern as population expansion demands more food production. While not directly about microplastics, healthy soil management is relevant because degraded soils are more vulnerable to microplastic accumulation and contamination.
The Hidden Threat: How Plastic Pollution Is Affecting Soil Fertility
AI summary Read the abstract
Researchers examined how plastic waste in agricultural soils undergoes both abiotic fragmentation — from plowing, UV exposure, and weathering — and biotic transport through soil invertebrates and vertebrates, ultimately accumulating in plant root systems and entering the food chain in ways that threaten soil ecology and human consumers.
