This study investigates the effects of residual films on soil salt transport and crop growth. An experimental study was conducted wherein the soil was collected from cotton fields under long-term film mulching and drip irrigation in arid oasis areas to determine the distribution and accumulation of residual plastic films in the soil layers of an agricultural ecosystem. The results from the study indicated that the density of residual mulching film in cotton fields under continuous mulching for five years exceeded the limit value of the determination standard (75 kg/ha). With the increase in film mulching years, the residual film accumulated at a rate of 15.0 kg/ha annually, and it tended to migrate to the deep soil each year. The growth index, biomass, and yield also show a decreasing trend with the increase in the number of mulching years. The analysis of this study indicates the significance of increasing the recycling efficiency of the residual films and ensuring sustainable agricultural development in an oasis.
The Ocean Plastics Charter aims to bring together leading countries, sub-national governments, businesses, and civil society organisations to commit to a more resource-efficient and sustainable approach to keep plastics in the economy and out of the environment. With this charter, it aims to transition to a more sustainable and resource-efficient method of managing plastics. Through[…]
These regulations are intended to promote sustainable development, food security, and the sustainable management of fishing activities in Palau’s waters. They also intend to create economic returns, employment generation, and export earnings from the sustainable harvesting of tuna and tuna-like species by encouraging the development of domestic fishing industries and a local tuna market. These[…]
This subchapter E of Title 40 of the Code of Federal Regulations outlines the pesticide programs, including registration and classification procedures, policies, special review procedures, standards, labelling requirements, packaging requirements, data requirements, and good laboratory practice standards. It also covers state registration of pesticide products, rules of practice governing hearings under the federal Insecticide, Fungicide,[…]
The Plastics Roadmap aims to decrease littering and other environmental harm brought on by plastics, prevent needless use, enhance plastic recycling, and replace traditional polymers derived from fossil fuels combined with various substances and liquids. To guarantee more focus on sustainable product development, reuse, product recyclability, and the growing usage of recovered plastics, these objectives[…]
The regulations aim to enhance aquaculture pollution prevention and control, protect aquatic ecosystems, ensure product quality and safety, and promote sustainable development. They consist of 24 articles divided into four sections: general provisions, delimitation of prohibited areas, pollution prevention and control, and environmental monitoring and supervision of fishery waters.
