The Effects of Garbage on Plant Growth

The Chemical Industrial Waste Crisis

• Composting is the decaying activity that occurs normally in nature. Controlled composting speeds the rate of organic garbage decomposition and reduces the material's volume to produce rich humus that enhances plant growth and vigor. Sufficient amounts of nutrients, air and water are vital for microorganisms to break down the raw scraps and transform them into usable plant food. Compost core temperatures of over 140 degrees will destroy most weed seeds and pathogens for a safe end product.

Biological Consequences of Toxic Plants

• Perhaps the most destructive global effect of garbage on plant growth is cellular distortions. Environmental contaminates can be passed along plant generations. Plant cells inundated with toxic material produce promutagens, precursors to mutations. According to the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois, promutagens do not alter a plant's original genetic material but will reproduce mutated offspring. Further studies aim to identify antimutagens that may reduce chemical toxin damage.

Reclaiming Lawn and Kitchen Garbage

• Everyday kitchen and yard refuse has the potential to produce some of the greatest improvements in plant growth. Dead leaves and grass clippings provide protective mulch for young and established plants to conserve water and dissuade weeds from hogging nutrients. Vegetable scraps and leftover food without meat products that normally would be put down garbage disposals or end up in landfills can transform into delightful plant food. Compost nutrients enrich the soil with natural elements that make plants grow faster and healthier.

Composted Landfill and Plant Development

• Composted landfill garbage greatly increases the nutrient value of the soil and crop productivity. As landfill compost is increased in the soil, tomatoes and fruits show a greater response in growth to the additional nitrogen levels. Although 25 to 40 percent of land disposal system solid waste can be composted, there is also a high amount of inorganic materials that remain. These materials must be screened and removed before the compost can be used on plants.
