Garden Bed
Raised-bed gardening is a form of gardening in which the soil is raised above ground level and usually enclosed in some way. Raised bed structures can be made of wood, rock, concrete or other materials, and can be of any size or shape. The soil is usually enriched with compost. Vegetables are grown in geometric patterns, much closer together than in conventional row gardening. The spacing is such that when the vegetables are fully grown, their leaves just barely touch each other, creating a microclimate in which weed growth is suppressed and moisture is conserved. Overview Raised beds lend themselves to the development of complex agriculture systems that utilize many of the principles and methods of permaculture. They can be used effectively to control erosion and recycle and conserve water and nutrients by building them along contour lines on slopes. This also makes more space available for intensive crop production. They can be created over large areas with the use of several ...

Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, cups, jars, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'' and many variations thereof. Its properties can be modified further by crosslinking or copolymerization. All forms are nontoxic as well as chemically resilient, contributing to polyethylene's popularity as a multi-use plastic. However, polyethylene's chemical resilience also makes it a long-lived and decomposition-resistant pollutant when disposed of improperly. Being a h ...

Rock (geology)
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its Chemical compound, chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the Earth's crust, crust, and most of its interior, except for the liquid Earth's outer core, outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zucchini
Zucchini (; : ''zucchini'' or ''zucchinis''), courgette () or ''Cucurbita pepo'' is a summer squash, a Vine, vining herbaceous plant whose fruit are harvested when their immature seeds and Fruit anatomy#Epicarp, epicarp (rind) are still soft and edible. It is closely related, but not identical, to the Marrow (vegetable), marrow; its fruit may be called ''marrow'' when mature.

Garlic Chive
''Allium tuberosum'' (garlic chives, Oriental garlic, Asian chives, Chinese chives, Chinese leek) is a species of plant native to the Chinese province of Shanxi, and cultivated and naturalized elsewhere in Asia and around the world. It has a number of uses in Asian cuisine. Description ''Allium tuberosum'' is a rhizomatous, clump-forming perennial plant growing from a small, elongated bulb (about , across) that is tough and fibrous. Unlike either onion or garlic, it has strap-shaped leaves with triangular bases, about wide. It produces many white flowers in a round cluster (umbel) on stalks tall. It grows in slowly expanding perennial clumps, but also readily sprouts from seed. In warmer areas (USDA zone 8 and warmer), garlic chives may remain green all year round. In cold areas (USDA zones 7 to 4b), leaves and stalks completely die back to the ground, and resprout from roots or rhizomes in the spring. The flavor is more like garlic than chives.
