What is a specialty agriculture?
Specialty crops are defined in law as “fruits and vegetables, tree nuts, dried fruits and horticulture and nursery crops, including floriculture.” This definition, although more exact than previous legal definitions, leaves a certain amount of latitude in interpretation. Fruits, vegetables, tree nuts, nursery crops and
What are examples of specialty crops?
USDA’s list clarifies that “specialty crops” include fruits and tree nuts,4 vegetables, culinary herbs and spices, medicinal herbs, and other horticulture products (including honey, maple syrup, coffee, tea leaves, turfgrass, and hops5).
Are specialty crops intensively cultivated?
The Specialty Crop Competitiveness Act of 2004 and the Food, Conservation, and Energy Act of 2008 have defined specialty crops as “fruits and vegetables, tree nuts, dried fruits, horticulture, and nursery crops (including floriculture).” Eligible plants must be intensively cultivated and used by people for food,
What are specialty crops AP Human Geography?
specialty crops. crops including items like peanuts and pineapples, which are produced, usually in developing countries, for export. subsistence agricultural economy. any farm economy in which most crops are grown for nearly exclusive family or local consumption.
What are value added specialty crops?
marketing crops like organically grown grains, potatoes, carrots, beans, tomatoes and corn for sweeteners and fuels, to. producing specialty cheeses and even alfalfa-based biomass for a local power plant.
Where are terraces used?
Terrace farming was invented by the Inca people who lived in the South American mountains. This farming method has made cultivation of crops in hilly or mountainous regions possible. It is commonly used in Asia by rice-growing countries such as Vietnam, Philippines, and Indonesia.
What are the three main types of terracing?
There are three types of terraces: bench terraced farmlands, sloping terraced farmlands and combination level terraced farmlands.
What are terraces used for in agriculture?
Graduated terrace steps are commonly used to farm on hilly or mountainous terrain. Terraced fields decrease both erosion and surface runoff, and may be used to support growing crops that require irrigation, such as rice.
What is contour in agriculture?
Contour farming, the practice of tilling sloped land along lines of consistent elevation in order to conserve rainwater and to reduce soil losses from surface erosion.
Why are terraces useful?
What are the benefits of a terrace system? The major benefit, of course, is the conservation of soil and water. Terraces reduce both the amount and velocity of water moving across the soil surface, which greatly reduces soil erosion. Terracing thus permits more intensive cropping than would otherwise be possible.
How many types of terraces are there?
There are three kinds of terraces (a) bench terraced farmlands; (b) sloping terraced farmland; (c) combination level terraced farmlands and natural slope land. Bench terrace is the basic type of farmland in mountains. A bench terrace with its level platform and projected or ridged rim may hold rainwater for irrigation.
Why are terraces not suitable for farming?
Due to the leaching process, terrace farming can lead to a reduction in soil quality. Leaching is the loss of water-soluble plant nutrients from the soil, because of rain and irrigation.
What is bench terracing?
Bench terraces are a series of level or virtually level strips running across the slope at vertical intervals, supported by steep banks or risers.
Can terracing prevent erosion?
Terraces prevent erosion by shortening the long slope into a series of shorter, more level steps. This allows heavy rains to soak into the soil rather than run off and cause erosion.
What are the advantages and disadvantages of terrace farming?
The primary advantage of terraces is improved soil erosion control. Secondary advantages of terraces include elimination of grass waterways that can be difficult to maintain and reductions in flooding. Disadvantages include the capital cost of building terraces, and the time required to maintain terraces.
How do you build a wall to prevent erosion?
Materials List. Some gardeners do have luck with walls built of loosely stacked stone or of wood. Although you can build a retaining wall out of just about anything, the best and sturdiest ones rely on tightly stacking concrete blocks, bricks or stone pavers that resist the pressure from the soil behind them.
