Agricultural plastic mulching as a source of microplastics in the terrestrial environment.

Environmental Pollution, 2020
Plastic mulching is suspected to be a significant source of microplastics in terrestrial environments owing to its intensive application and improper disposal. However, there has been a comparative lack of studies examining this hypothesis. In this study,

Distribution and weathering characteristics of microplastics in paddy soils following long-term mulching: A field study in Southwest China.

Science of the Total Environment, 2022
Agricultural plastic-film residues have been considered as one of the important sources of microplastics in the agroecosystem. However, less researches were conducted on the accumulation of microplastics in long-term film-mulched paddy soil.

Effects of plastic mulching and plastic residue on agricultural production: A meta-analysis.

Science of the Total Environment, 2019
China is a large agricultural country, and food security is significantly limited by the shortage of water resources. Plastic mulching technology can effectively modify the crop growth environment and crop production due to differences in climatic ...

By increasing infiltration and reducing evaporation, mulching can improve the soil water environment and apple yield of orchards in semiarid areas

Agricultural Water Management, 2021
Infiltration and evaporation are two important components of soil water balance in semiarid areas. For local orchards using drip irrigation, rainfall and irrigation events have a profound impact on soil infiltration and evaporation. As an effective water

Long-term straw mulching with nitrogen fertilization increases nutrient and microbial determinants of soil quality in a maize–wheat rotation on China's Loess Plateau

, 2021
Mulching and nitrogen (N) fertilization are essential to increase crop yields in semiarid drylands. However, their long-term effects on soil physicochemical properties, extracellular enzyme activities, microbial community structure, and therefore soil ...

Soil mulching and deficit irrigation effect on sustainability of nutrients availability and uptake, and productivity of maize grown in calcareous soils

Communications in Soil Science and Plant Analysis, 2021
Plants are subjected to low use efficiency of water and nutrients in marginal lands such as calcareous soils. Moreover, plant wastes are not utilized optimally by the farmers.

Microplastics in agricultural soils: Extraction and characterization after different periods of polythene film mulching in an arid region.

Science of the Total Environment, 2020
Plastic film mulching has been extensively used in farmland, especially in arid regions, for over half-century. However, this has led to heavy pollution of soils by microplastics (MPs).

The effects of plastic film mulching and straw mulching on licorice root yield and soil organic carbon content in a dryland farming.

Science of the Total Environment, 2022
The increasing worldwide demand for traditional herbs has been met by growing cultivated herbs. It is undoubtedly very important to seek a reasonable cultivation mode for the yield, quality and long-term production stability of traditional herbs. In this
