TERRA PRETA (“dark earth” in Portuguese) refers to expanses of very dark, fertile anthropogenic soils found in the Amazon Basin. It owes its name to its very high charcoal content. It is also known as “Amazonian dark earth”. テラプレタポルトガル語（"暗い大地"）は非常に暗く、肥沃な人為的な土壌アマゾン盆地で発見された広がりを指します。これは非常に高い炭のコンテンツへの名前の由来。また、アマゾンの暗い大地""として知られている。
Efforts to recreate these soils are being undertaken by companies such as Biochar Energy Corporation, Eprida and Best Energies . Research efforts are underway at Cornell University, the University of Georgia, Iowa State University and Geoecology Energy Organisation. Biochar is the main (and likely key) ingredient in the formation of terra preta. One focus of these researchers is the prospect that if biochar becomes widely used for soil improvement, it will involve globally significant amounts of carbon sequestration, remediating global warming. 取り組み、これらの土壌を再現するBiocharエネルギー株式会社Epridaとベストエネルギーなどの企業によって行われている。研究の取り組み、コーネル大学で進行中で、ジョージア大学、アイオワ州立大学とGeoecologyエネルギー機構のです。 Biocharの（そしておそらく）テラプレタの形成の食材キーmainです。これらの研究の焦点の一つの見通しがbiochar広く土壌改善のための使用になりますが、それをグローバル炭素隔離の重要な金額を伴うが、地球温暖化の修復されます。

Here are the 10 reasons we believe everyone should consider planting a organic vegetable garden this year.
- Cost savings: We have spent approximately $50 in supplies and seeds, with an estimate of $100 for additional spending in the future to outfit the garden with a composting system as well as any additional supplies as needed. Contrast this with $40-$50 we spend on veggies every other week.
- Great tasting nutritious food and peace of mind: It is great to know exactly how your vegetables are grown and not having to worry about pesticides and other toxins. Besides, freshly harvested organically grown vegetables taste great!
- Energy savings: Your vegetables are grown locally, by you, and does not need to be transported 3000 miles from a farm to your table. Consider the amount of fossil fuel that can be saved if a significant proportion of us started consuming locally produced vegetables
- Environmentally friendly: Using organic methods of growing vegetables is environmentally friendly as no toxic chemicals are mixed into the soil. Additionally, composting the scraps of your garden returns the organic material back to the soil
- Exercise: Working in a garden is a great form of exercise that can be performed by almost everyone.
- Clean air: As long as you are working outside, you are getting fresh clean air. But most of all, replacing a part of your lawn with a vegetable garden can produce greater amounts of oxygen for the atmosphere and reduce greenhouse gases.
- Reducing landfills: If you compost, you will be using up most of the organic kitchen waste, grass clippings, dead leaves, etc from the yard to feed your garden. This means less garbage to put out, less use of plastic garbage bags and paper garden waste bags. A great review of different composting techniques can be found at Amy Stewart’s blog.
- Getting back to the nature: Yes, we have lost our touch with the nature as we navigate out way through the material world. Working in a garden forces you to look at nature in a new light and with greater respect.
- Stress relief: Gardening is a great stress reliever as you are focus on the task at hand you leave behind your worries from work and business. Atleast for some time.
- Bonding and education: For many of us who have small kids, getting them to help out with the garden is a great way of spending time together and strengthen our bonds. It also allows us many teachable moments with our kids.
The researchers also found that while in developed countries, organic systems on average produce 92% of the yield produced by conventional agriculture, organic systems produce 80% more than conventional farms in developing countries, because the materials needed for organic farming are more accessible than synthetic farming materials to farmers in some poor countries. On the other hand, communities that lack sufficient manure to replenish soils would struggle with organic farming, and the soil would degrade rapidly[17] . 研究者たちは、平均して、有機システムでは、収量、従来の農業、有機システムによって生産の92％を生産し、先進国は、一方が生産、開発途上国で従来の農家80％以上、これは、材料、有機農業のために必要以上の合成も可能です以上いくつかの貧しい国々の農民への農業資材。一方、コミュニティではない、十分な肥料有機農法と戦うだろう、と土壌を補充するための土壌が急速に劣化させる[17]。
