Soil - 1 views

  • Heavy soils are those with a large component of clay in them, because the clay particles bind together to form a heavy, sticky lump which is difficult to dig. Because it is composed of so many fine particles which stick together easily, it is liable to compaction. It holds a lot of water and easily becomes waterlogged, so it is cold and wet in spring, and takes a long time to warm up.
  • Clay soils are usually acidic
  • Heavy clay soils can be improved by adding humus or other organic matter and sharp sand for better drainage

  • Medicinal plants have always been considered a healthy source of life for all people.
  • Therapeutical properties of medical plants are very useful in healing various diseases and the advantage of these medicinal plants is being 100% natural.
  • Nowadays people are being bombarded with thousand of unhealthy products, the level of sensibility infront of diseases is very high and that's why the use of medicinal plants can represent the best solution

Plant Physiology Online: Phototropism: From Photoperception to Auxin-Dependent Changes ... - 0 views

  • Phototropism—the directional curvature of organs in response to lateral differences in light intensity and/or quality—represents one of the most rapid and visually obvious responses of plants to changes in their light environment
  • In nature, stem phototropism likely provides plants with an effective means for maximizing photosynthetic light
  • signal-response components mediating the basal UV-A/blue light-induced phototropic response in seedlings.
  • ...2 more annotations...
  • Phototropism has been the subject of study for more than 120 years
  • Photoreceptor molecules, the phototropins, capable of perceiving directional UV-A/blue light cues have been identified and characterized.

    This page elaborates on the Essential Plant Nutrients. This time, talking about the nutrients that are found in the soil itself.

    The project that i would like to do would have something to do with different soils and the different amount of nutrients' they contain effects on the plants.

Does Music Affect Plant Growth? | eHow.com - 0 views

  • Plants do like noise. Plants exposed to a set frequency of sound tend to germinate more quickly, grow taller and weigh more than those kept in silence. Both 50,000 hz ultrasound (above the human hearing range) and 5,000 hz sound seem to work. Therefore, there's a good chance that plants like any sound you might play for them, including music.
  • Plants also like good, attentive care. If you are playing music you like for a plant, it may lead you to take better care of it. You will be more likely to carefully water and feed the plant and make sure it has good light. It might look like the music helps the plant grow, when you are actually taking better care of it. Plants like carbon dioxide. If you are standing by a plant, singing to it, it is going to absorb some carbon dioxide from your breath. This could help it to grow more quickly.

      From no effect to drastic. These results are pretty varied.
  • the high frequency of mechanical waves that run hand in hand with rap and acid rock are damaging to the plant.
  • Plants have no auditory organs. They can't hear any more than you could hear through your skin if you had no ears.

      Just as deaf people can feel vibrations, I would assume that plants can feel the vibration of the music. Either gentle music or jarring music

What effect does music have on plant growth? - 0 views

  • The one that was in the best condition was the plant that was in the room with classical music. The second best plant was the one in the room with no music and the one that didn't do so good was the one in the room with rock music.
  • and Rap was last!
    • emily shy
       
      Interesting. Maybe because of all the drum effects it would cause the plants to be unsettled?

      The plants were actually trying to avoid the music because it stunts their growth! That is incredible!!!
  • with the same song played by strings, the plants bent towards the speaker.

      Strings as opposed to drums and steel percussion. It seems like that is more appealing to humans as well

  • leaned 30 to 70 degrees away from the speakers
  • The plants in the first chamber, with the constant tone, died within fourteen days.
  • Her first experiment was to simply play a constant tone
  • In the chamber with the soothing music, the plants were growing healthily and their stems were starting to bend towards the radio! In the rock chamber, half the plants had small leaves and had grown gangly, while the others were stunted. After two weeks, the plants in the soothing-music chamber were uniform in size, lush and green, and were leaning between 15 and 20 degrees toward the radio. The plants in the rock chamber had grown extremely tall and were drooping, the blooms had faded and the stems were bending away from the radio.

Soil pH, Fertilizers, and Lime - 1 views

  • Lime works best when it is mixed with the soil so it can come in contact with a large volume of the soil water. Since lime is not very soluble, it moves into the soil very slowly when applied to the soil surface
  • A little too much can raise pH to undesirable levels and keep it there, causing serious management problems. Make certain you know how much lime is needed, then apply it over a number of seasons until your soil is back in balance.

Are Electrolytes Good For Plants - 0 views

  •  
    certain electrolytes allow nutrients to move through the plant cell membrane, possibly allowing for quicker growth which could be essential for a plants survival if it needs to grow faster than a weed or something harmful to it.
