1、Use of plastic mulch in agriculture and strategies to mitigate the

Even a continuous application of biodegradable mulch (BDM) film that passes the ASTM D6400–12 a standard developed by “American Society for Testing and Materials” for composting, would theoretically, allow the accumulation of (i) plastic particles less than 2.0 mm in size, (ii) 10% of organic carbon left after 180 days, (iii) up to 5% ...

2、Effects of film mulch and phosphorus application on soil phosphorus

Two mulch treatments (no film mulch and film mulch) and four P fertilizer regimes [0, 9.7, 19.2, and 28.8 kg (P)∙hm −2] were employed to determine their effects on soil P fractions and their determinants in alfalfa grassland over different treatment durations (years 3 and 9).

Impacts of plastic film mulching on crop yields, soil water, nitrate

Our study can provide a comprehensive assessment on the impacts of the plastic film mulching. We assessed the effects of plastic film mulching on soil physical and biochemical properties.

The use of plastic film mulch is a modern agricultural technique that involves covering the soil surface with a plastic film to retain soil moisture and temperature, thereby promoting crop growth. For phosphate fertilizers, plastic film mulch can enhance the availability of phosphorus in the soil by preventing water evaporation, which facilitates easier absorption of phosphorus by plants. several factors must be considered to maximize the effectiveness of this practice.

First, the thickness and density of the plastic film significantly impact its performance. Generally, thicker and denser films provide better insulation and moisture retention, but they may also restrict root growth. the choice of film should balance local climatic conditions, crop type, and soil properties.

Second, the amount of plastic film used requires careful consideration. Typically, 1–2 kilograms of film per mu (approximately 0.067 hectares) is recommended. This quantity can be adjusted based on crop species, growth stages, and soil conditions. For fast-growing crops like corn or wheat, slightly more film may be applied, while longer-season crops such as rice or cotton require more controlled usage.

Additionally, integrating plastic film mulch with other agricultural practices is critical. Pre-planting deep tillage and soil loosening improve aeration and water retention, enhancing the film’s effectiveness. Rational fertilization is equally essential; applying phosphate fertilizers in appropriate amounts alongside film mulch ensures optimal crop growth.

Lastly, environmental concerns must be addressed. While plastic film reduces water loss, improper disposal can lead to soil pollution due to its non-biodegradable nature. Over-reliance on film mulch may also waste land resources. Thus, environmental awareness and measures to minimize pollution, such as recycling or biodegradable alternatives, should accompany its use.

plastic film mulch is a valuable tool for boosting crop yields and growth. its effectiveness depends on thoughtful consideration of film thickness, application rates, integration with other practices, and environmental sustainability. Only through rational use can this technology fully support agricultural productivity.
