phase 1 investigation

Vermicompost
BY Ernesto Gispert Lopez, Kei Nishiumura, Emile Fiset and Jean Michel Armenta
Phase 1
Objective: create organic fertilizer through knowing the vermicompost and report to the community about it.
Erosion of soil
Causes
It depend on many factors, such as precipitation, temperature, seasonality, wind speed and storm frequency, also rock type, and slope of the land. The erosion is the process of weathering and transport of solids in the natural environment or their source and deposits them elsewhere. It usually occurs due to transport by wind, water, or ice. So imagine if now it’s affecting us in the global warming it will destroy us. Is generated by the destruction of wetlands like swamps, because they work as retainers with the ocean.

Consequences
This brings the reduction of land and the destruction of complete ecosystems.

Fertilization methods
Organic
The humus is an organic fertilization method that increases the water holding capacity and easily absorbs the sun rays. Humus also liberates the compounds for plants from the soil and provides fertilization and improves soil texture quality. Humus is added to the soil by using an organic fertilizer such as manure or the contents of a compost pile. Humus can also be bought directly, however the expense is prohibitive if going to be used in a large area and needs treatment. Organic fertilizer nutrient content, solubility, and nutrient release rates are typically all lower than inorganic fertilizers. The humus can be made naturally, with normal compost or with vermicompost.

Inorganic
The inorganic fertilization produces eutrophication, soil acidification, persistent organic pollutants, heavy metal accumulation and atmospheric effects.

Composting history

Prehistoric farming people discovered that if they mixed manure from their domesticated animals with straw and other organic waste, such as crop residues, the mixture would gradually change into a fertile soil-like material that was good for crops. Composting remained a basic activity of farming until the twentieth century, when various synthetic fertilizers were found to provide many of the nutrients occurring naturally in compost


It was in an underdeveloped country—India—that modern composting got its big start. Sir Albert Howard, a government agronomist, developed the so called Indore method, named after a city in southern India. His method calls for three parts garden clippings to one part manure or kitchen waste arranged in layers and mixed periodically. Howard published his ideas on organic gardening in the 1940 book An Agricultural Testament.

Vermicomposting
Vermicompost is the product or process of composting utilizing various species of worms, usually red wigglers, white worms, and earthworms to create a heterogeneous mixture of decomposing vegetable or food waste, bedding materials, and vermicast.

Materials:
• A worm bin
• Bedding,
• Water,
• Red worms
• Compost scraps such as waste fruits and vegetables, coffee filters, eggshells, and fruit and vegetable peelings
