(Greek: earth, land, soil; world; Gaia (Greek), Gaea (Latin), "earth goddess")
2. Turning away from the earth: Elena was studying plant ageotropism and so she was growing plants in a gravity free environment.
3. A reference to parts of plants that would be expected to grow as gravity pulls them down, but instead grow upward; such as, the knee roots of cypress trees: Marcella tripped over the ageotropisms of the tree in the swamp because the roots were sticking up out of the earth.
Additional details regarding agrogeological fertilization
By adding rock dust as a complete plant fertilizer along with plant matter, the soil may be much healthier.
- Rock dusts contain most of the nutrients essential for growth except for nitrogen and phosphorous.
- The release of nutrients is directly related to weathering; therefor, their beneficial effect could last for many years before needing replacement, and even longer if used in conjunction with sustainable farming techniques.
- The problem of nutrient leaching is minimized as plants take up the nutrients at the same rate as they are being released and there is also minimal problem with toxicity from oversupply of nutrients.
- Some dusts raise pH, countering the effects of soil acidity often found in certain soils.
If the soil is healthier then the plants will be healthier. Mixed rock dust can provide a full spectrum of minerals to the soil and this improves cellular structure, which could explain why rock dusted plants are more resistant to insect attacks and diseases.
It has been noted that the use of rock dust can reduce (or even replace) fertilizers, pesticides, fungicides and herbicides.
2. The study of minerals of importance to farming and horticulture, especially with regards to soil fertility and fertilizer components. These minerals are usually essential plant nutrients and are referred to as agrominerals.
Expanding the understanding of agrogeology
Agrogeology is the study of the natural fertilization that takes place when weathering breaks rocks into their constituent elements. It was first studied in the early nineteenth century; however, the success of the artificial fertilizers eliminated interest in this natural approach until the late 1970s when Dr. Chesworth, a geologist at the University of Guelph in Ontario, Canada, combined his theoretical studies of rock decomposition to determine that weathering of a common volcanic rock like basalt made land more fertile.
Continuing studies indicate that volcanic rocks like basalt, supply the nutrients necessary for plant and animal growth. The essential elements for plant growth include: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum and chlorine. In addition, the presence of rock fragments in the soil and on the soil surface significantly influences infiltration, runoff, and moisture storage, all of which significantly effect plant growth.
In recent years, soil scientists have conducted numerous studies to reduce the application of chemical fertilizers on the nation's farmlands. Results from these analyses indicate remineralization can achieve a series of benefits:
- Combat the effects of pests and diseases that effect plant growth.
- Reduce the water requirements necessary for plant growth.
- Lower the cost of production and produce higher yields on treated lands.
- Provide the necessary nutrients to increase the quality and quantity of the plants grown.
2. Extending all over the earth from the equator to both poles.
2. The study of the distribution of human types by their cultural traits and the ethnic and racial distributions of humankind over earthly areas.
2. Etymology: from anti-, "against" plus Gaea, "earth goddess".
2. The points in the orbits of the moon, or of an artificial satellite, that are most distant from the center of the earth.
3. The point in an orbit that are most distant from the body being orbited.
4. The farthest, or highest, point; a culmination.
When the end came, however, it came so quickly that people were caught wherever they were. Hundreds of people in Herculaneum, who had time to run and find refuge in doored arched storage caverns, were still exposed to such surface temperatures. It is written that a hand raised to protect the face was burned to the bone, while the other hand, unexposed to the blast, was not.
