  • Soil Test Lab Report

    The purpose of this lab was to test for which soil type would be best for food production. The tests included Forest Soil, Floodplain Soil, and Garden Soil. We predicted that garden soil will have the best properties for food production because we expected it to have the highest value of nutrients for plants to grow in and a soil composition that is fit for food production (ex. Water Holding, etc). To test our hypothesis, we ran tests measuring Percent Water Content, Organic Material, Nitrates,…

  • Relative Density Of Species

    Temperate deciduous forests themselves are affected greatly by global factors, like climate change, and human agriculture (Reich et al 2002); the woody plants that populate the majority of them are distributed based on things like soil moisture, soil nutrients, soil pH, flooding patterns, elevation, and light (Hosner 1958, Bell 1980, Menges 1983). These factors play into how the species interact and compete with one another, and how…

  • Consequences Of Herbicide Persistence

    An important chemical property of soil that can affect herbicide persistence is pH. Soil composition is a physical factor determined by the relative amounts of sand, silt, and clay in the soil (the soil texture), as well as by the organic-matter content. The types and abundance of soil microorganisms present in the soil make up the microbial aspects of the soil environment. Generally, soils high in clay, organic matter, or both have a greater potential for herbicide…

  • What Is Mycorrhiza?

    MYCORRHIZAE AND FORESTRY What is Mycorrhiza: Albert Bernard Frank (1885), in his study of relationships between soil microbes and plants, introduced the Greek term ‘mycorrhiza’, which means ‘fungus roots’. Mycorrhizas are highly evolved symbiotic association between roots of most higher/vascular plants and certain specialized soil fungi (Ascomycetes, Basidiomycetes and Zygomyectes) that colonize the root cortex during periods of active plant growth both in the natural environment and in…

  • Synthesis Acid Rain

    Johnson 125). The researchers discovered that when the synthesized acid rain reached pH levels below 2.0, there were significant reductions in the germination of such plants (McColl and Johnson 127). Additionally, some of the germination rates in certain firs and pines were reduced by up to 32 percent (McColl and Johnson 125). Also, there were related problems to the plants that were exposed to the acid rain with pH levels below 2.0. The plants appeared to have problems absorbing and utilizing…

  • Water Temperature Affecting Aquatic Organisms

    Temperature is one of the water characteristic or more precisely one of the physical water parameters. Water temperature affects almost all other water quality parameters. It plays a key role in aquatic life and habitations. Thus, the fluctuation of temperature controls what aquatic kind will live and bloom in the water body. Water temperature can also affect “the metabolic rates and biological activity of aquatic organisms”. Therefore metabolic rates of aquatic organisms is directly…

  • Case Study Of Sumatera Forest Fires

    1.1 Case Study Sumatera has one of the largest rain forests in Indonesia as well as in South East Asia. Sumatera Forest basically has peat soil type that caused easier to burn. Estimated between 7.3 to 9.7 hectares are covered by peat lands or roughly a quarter of the entire area of peat lands in the tropics (Hisyam, Damanik, Anwar, 1984). Sumatera Forest Fires are the one of the serious problem in Indonesia. It happened almost every year. However, some of the biggest were happening in 1982,…
