Specification

Description:FIELD OF THE INVENTION
This invention relates to sustainable agricultural technology, focusing on a dual-layer biodegradable mulch film designed to conserve soil moisture, prevent erosion, and regulate soil temperature. The film is particularly suitable for climates with alternating wet and dry seasons, offering an eco-friendly alternative to plastic mulches in agricultural practices.
BACKGROUND OF THE INVENTION
Traditional plastic mulches used in agriculture contribute significantly to soil and environmental pollution, as they do not biodegrade and often leave toxic residues after disposal. While biodegradable mulch films exist, they primarily focus on moisture retention without addressing the broader challenges of erosion, nutrient retention, and temperature regulation specific to diverse climatic conditions, such as those found in Indian agriculture. Heavy monsoons and extended dry seasons can result in soil degradation, inconsistent moisture levels, and nutrient depletion. This invention addresses these issues by introducing a multifunctional biodegradable mulch film designed with UV-reflective properties, moisture retention capabilities, and erosion prevention features. It is engineered to decompose naturally, leaving no harmful residues, thus supporting sustainable agricultural practices.
SUMMARY OF THE INVENTION
This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention.
This summary is neither intended to identify key or essential inventive concepts of the invention and nor is it intended for determining the scope of the invention.
To further clarify advantages and features of the present invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof, which is illustrated in the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope. The invention will be described and explained with additional specificity and detail with the accompanying drawings.
The invention provides a dual-layer biodegradable mulch film composed of a top UV-reflective layer and a bottom moisture-retaining layer. The top layer, made from a biodegradable polymer infused with aluminum flakes, reflects sunlight, preventing excessive soil heating and conserving moisture. The bottom layer, made from natural materials like coir pith or bagasse, acts as a moisture reservoir, absorbing water during rainy periods and releasing it slowly in dry conditions. Micro-perforations within the film allow optimal air and moisture exchange, enhancing soil health. The biodegradable nature of both layers ensures environmental compatibility, as they decompose into the soil without leaving harmful residues.

The dual-layer biodegradable mulch film is engineered to provide multifaceted support for agricultural soils in varying climatic conditions. The top layer is composed of a biodegradable polymer infused with reflective additives, such as aluminum flakes, which reflect UV rays. This UV-reflective layer helps regulate soil temperature, minimizing overheating during peak sunlight hours. The materials used are selected for their ability to break down naturally through microbial activity, ensuring that the film decomposes fully over time without leaving toxic residues in the soil. The reflective properties of this layer also aid in repelling pests that are deterred by UV light, adding an additional protective benefit for crops.
The bottom layer of the film is constructed from natural, biodegradable materials such as coir pith or bagasse, chosen for their high water-absorbing properties. During periods of heavy rainfall, this layer absorbs excess water, preventing waterlogging in the soil. In dry periods, the absorbed water is gradually released, ensuring consistent soil moisture levels. Embedded within the bottom layer are micro-perforations that adjust based on temperature and humidity, allowing for optimal air exchange and preventing excessive moisture build-up. This unique feature contributes to healthier soil conditions by enabling airflow and moisture regulation at the root zone.
To enhance soil stability, jute fibers are integrated into the film, which helps prevent soil erosion during heavy rains, a common challenge in monsoon-prone regions. The jute fibers reinforce the film, increasing its durability and ensuring that it remains intact under varying environmental conditions. Additionally, the film is designed with ridges that channel rainwater towards the roots of plants, promoting efficient water usage and reducing runoff.
The film's dual-layer structure, combined with its reflective, absorptive, and erosion-preventive properties, addresses multiple agricultural challenges in a single product. It is suitable for a wide range of crops and offers a sustainable, eco-friendly alternative to traditional plastic mulches, aligning with global efforts to reduce agricultural plastic waste and promote soil health.
