  • Plants Lead Prey Into Their Trap
    1,519 words
    Carnivorous Plants In a world where plants are at the bottom of the food-chain, some individual plant species have evolved ways to reverse the order we expect to find in nature. These insectivorous plants, as they are sometimes called, are the predators, rather than the passive prey. Adaptions such as lures and trapping mechanisms have made it possible for these photo synthesizers to capture, chemically break-down and digest insect prey (and in some cases even small animals.) There is no reason ...
  • 25 Phosphorous Nutrient Deficiency Plants
    1,969 words
    Phosphorous Nutrient Deficiency of Sunflowers, Helianthus annuusNgoc Chau Tran Cal State Fullerton Abstract: The objective of this experiment was to determine whether or not a complete nutrient solution would have increased stem width, height, and leaf length compared to 25% phosphorous. My hypothesis was that sunflowers with a complete solution of nutrients would have the same growth compared to sunflowers with 25% phosphorous deficiency. The experiment was conducted by setting up two groups of...
  • Three Solid Nitrogen Fertilizers
    643 words
    Fertilizers are substances added to the soil sprayed on leaves of plants to help them grow better or in some cases faster. Plants need twenty essen tail elements to help them grow. Plants make carbohydrates. A plant needs nitrogen, phosphorus, potassium, calcium, sulfur, and magnesium the most to grow healthy. Most soils naturally contain enough trace elements for field crops, but such elements must be added when certain fruits and vegetable plants are grown. Nitrogen, phosphorus, and potassium ...
  • Recovery Drip System The Excess Nutrient Solution
    1,478 words
    I decided to research Hydroponics, which is the growing of plants without soil in water to which nutrients have been added. Hydroponics has been used for over a century as a research technique, but not until 1929 were experiments conducted solely to determine its feasibility for growing commercial crops. There are now hydroponic home gardens and commercial cropping operations in the United States and many other countries. Under hydroponics, plants can be grown closer together than in the field, ...
  • Most Fertile Soils
    716 words
    Differences and Effects of Natural and Synthetic Fertilizers At the core of the growth and germination of plants lie the nutrients they receive from the soil. The nutrients required for growth are classified into two groupings, and micronutrient's. Micronutrients are those that are needed in very large amounts, and whose absence can do a great harm to the development of the plant life. These nutrients include calcium, nitrogen, phosphorus, and potassium, and are very sparse in most soils, making...
  • Estuaries Nutrients
    1,216 words
    An estuary is where the river meets the sea. Life in the estuary is depending upon salinity, which decreases from open ocean to the mouths of the inflowing rivers. As salinity declines, the assortment of life declines, because most estuarine organisms are marine. But they are high rich ecosystems, accounting for one-half the living matter of the worlds oceans. This high productivity is a result of a nutrient trap formed by the interactions of tides and inflowing rivers. Fresh water, lighter in w...
  • Organic Nutrients And The Fungi
    646 words
    Upon considering nutrition the primary factor to take into consideration is the metabolic strategy of the organism in question. Fungi are heterotrophic, obtaining both carbon and energy from organic compounds; they are chemo-organotrophs. Plants are autotrophic, they obtain their carbon from atmospheric CO 2 and their energy from light; they are photolithotrophs. The nutritional requirement of the organism is thus dictated by its nutritional strategies, this essay will concern itself with the co...
