Download file to see previous pages “A recent assessment found that about 40 to 60% of crop yields are attributable to commercial fertilizer use” (Coleman, Fuenta, and Mock 1978). There are many types of fertilizer out there today for the aid of plant growth. There are many ways to categorize types of fertilizers; they can be classified as either organic or inorganic. It can also be defined as a solid or a liquid fertilizer, along with different ingredients that produce different actions. “Organic fertilizer is all natural and includes things such as bat guano, compost, peat moss, wood ash and manure. These are general soil amendments. They don't burn or harm plants, and they can have long-term positive effects on the soil without damaging groundwater. Organic fertilizer, however, generally has lower nutrient concentrations than inorganic fertilizers” (Broschat and Moore 2003). Whereas inorganic fertilizer can be classified with the characteristics of. “Man-made and typically comes as a powder, pellets, granules or a liquid. Other chemicals that might be included in inorganic fertilizers include calcium, sulfur, iron, zinc and magnesium” (Broschat and Moore 2003). Research Questions 1. What are the specific effects of fertilizer on plant growth? 2. ...
Methods Soil was mixed using a 1:1:1 ratio of pet moss, vermiculite, and potting soil. One scoop of the soil was collected and misted with water until it was moist. Four potting trays with six cells each were gathered. The cells were filled half way with the moist soil. Five osmocote pellets were added to each of the cells. The cells were completely filled with the remaining moist soil. A pencil was used to poke three tiny holes in each of the cells. A seed was placed at the top of each hole. The holes were then lightly covered with soil. Each of the cells was labeled one through twelve for the control group and the experimental group. A diamond wick was inserted into each of the cells halfway and was folded over at the bottom. This was to help water enter the cell. Two tubs were filled with water and two pieces of fabric for each tub were soaked and draped over the top of the boxes. Two antiagal tabs were added to each tub of water to prevent algae from growing. One control tray and one experimental tray were placed on each of the tubs. The trays were mixed up so that if something happened to one of the tubs, there would still be a tub that could be examined. The trays were placed under the fluorescent bulbs in the classroom. Plant height, number of leaves, and number of buds were collected each week. Water was added to the tubs weekly as well. Data was analyzed using statistical t-tests. Ethical Considerations Ethics are the moral codes which are followed in a research. These codes are binding and need to be followed irrespective of any circumstance which may surround the research since they give us a remembrance of the researcher’s responsibility towards the people being researched (Chapman and Shaw 2000).

...types of formations. This is a great wonderful example of how plants show behavior. Tests have proven that there is no electrical or magnetic field in that area which might be affecting the growth of the plants. Also, there seems to be whatsoever no problem with the soil or the atmosphere in which these plants grow. So how do they show such behavior They have appeared in England, Canada, Japan, Australia, Germany, Belgium, Holland, Russia and other areas. The reason is a mutual understand and need for collective behavior within plants for communication and growth needs (Wolman, 1977). It is actually the plants who have...

Sniffing Out a Fertilizer Bomber

...Sniffing Out a Fertilizer Bomber For a bomb to detonate, everything must fit into place. Timothy McVeigh was a walking time-bomb since his youth, as each event in his life worked toward making a recipe for a fully capable and motivated terrorist. An unstable home, bullying at school, an early obsession with guns to solve his problems, feeling betrayed by the military, arms training, and a transient existence staying with militaristic friends… all these made the perfect ingredients to make a psychotic bomber. Everything interwove in McVeigh’s life to enshroud him with a garment of revenge. This is not to say that one’s upbringing and environment excuse or justify evil behavior; they do, however, provide crucial warning...

Effects of six selected antibiotics on plant growth and soil microbial and enzymatic activities

...to find out are the specific effects of sulfonamides, tetracyclines, tylosin, and trimthoprim on the soil and the plants that depend on it, especially when available data regarding it are scarce and inconsistent. This is important for farmers of agricultural crops such as rice who are using or considering the use of animal manure or treated urine for fertilizer and hydration, respectively. Briefly, different concentrations of analytical grade tetracyclines (chlortetracycline and tetracycline), tylosin, sulfonamides (sulfamethazole and sulfamethazine), and trimethoprim were tested for their phytotoxicity of sweet oat, rice and cucumber through observing their seed germination and...

In general, both the plastid and mitochondrial mutants stimulate the production of ROS, but with contradictory results on intercellular transport via PD. Salicylhydroxamic acid brings on ROS production in mitochondria and increases intercellular transport, while paraquat brings on oxidative redox modify in both plastids and mitochondria, thus decrease intercellular transport. Materials and methods Two sterilized Arabdopsis ecotype, expressing redox-sensitive GFP (roGFPI) and roGFPI2 targeted to the cytoplasm and mitochondria were grown on agar plates in a Conviron plant growth compartment under constant light at 22°C.

...The US Government should have a certification program for foods containing genetically modified ingredients. A genetically modified organism is a plant, animal or microorganism which is not made naturally such as crossing species (“GMOs: The Greatest Threat to Mankind”). Citizens are eating genetically modified food without any idea at all. These ingredients or organisms are produced and consumed in the United States without any labels. Until today, there is still a great debate whether or not the genetically modified ingredients or organisms pose threats to humankind. Thus the question whether or not the United States government should have a certification program for foods containing genetically modified ingredients...

Environmental effects on bacterial growth

...Environmental effects on bacterial growth Introduction There are a limited number of living organisms in the world that can survive under almost all possible environmental conditions. Living organisms are limited by the ecological circumstances by which their habitats experience. The limitations are set by the interactions that exist between the organisms physiology and the environment within where they live. Each particular species has a set of conditions where they can survive, reproduce and grow. Temperature, oxygen, pressure and nutrition are some of the environmental elements that constrain the growth of the species with bacterial included in the list. The central question for the...

Plant Tropisms

...Plant Tropisms and their Effects. Living organisms, plants and animals included must overcome three aspects in order to successfully reproduce and maintain their lineage. These three aspects are: food security and the different mechanism and processes through which an organism acquires it; self-protection from other organisms and from harsh climatic conditions and finally the ability to reproduce successfully. Unlike animals, sedentary higher plants do not have voluntary locomotive ability to enable them move to favorable climatic conditions, escape predators or disperse their reproductive organelles, and therefore must depend on some other means to achieve theses...
