U.S.A

The climate in USA varies across different parts of the country. Generally, the western and southern parts of US have warmer weather as compared to the eastern and northern parts. The eastern/northern parts of US experience harsh winters with heavy snowfall but the summers are pleasant. The western/southern part has extremely hot summers and comparatively tolerable winters

CLIMATE IN U.S.A

The characteristics of United States rainfall climatology differ significantly across the United States and those under United States sovereignty. Late summer and fall extra tropical cyclones bring a majority of the precipitation which falls across western, southern, and southeast Alaska annually. During the winter, and spring, Pacific storm systems bring Hawaii and the western United States most of their precipitation.

RAIN FALL

Nor'easters moving down the East coast bring cold season precipitation to the Carolinas, Mid-Atlantic and New England states. Lake-effect snows add to precipitation potential downwind of the Great Lakes, as well as Great Salt Lake and the Finger Lakes during the cold season. The snow to liquid ratio across the contiguous United States averages 13:1, meaning 13 inches (330 mm) of snow melts down to 1 inch (25 mm) of water.

CROPS

Genetically engineered (GE) crops (mainly corn, cotton, and soybeans) were planted on 169 million acres in 2013, about half of U.S. land used for crops. Their adoption has saved farmers time, reduced insecticide use, and enabled the use of less toxic herbicides. Research and development of new GE varieties continues to expand farmer choices.

Organic fertilizers are fertilizers derived from animal matter, human excreta or vegetable matter. (e.g. compost, manure).[1] In contrast, the majority of fertilizers are extracted from minerals (e.g., phosphate rock) or produced industrially (e.g., ammonia). Naturally occurring organic fertilizers include animal wastes from meat processing, peat, manure, slurry, and guano

FERTILIZER

Made of neem seed oil and sold under several trade names, this insecticide should be sprayed on plants at the first sign of infestation and is a broad-spectrum product. The seeds come from the neem tree, which is native to India. Neem seed oil is a slow-acting insecticide that may be harmful to house

Integrated organic farming

METHODS OF ORGANICE FARMING IN U.S.A.

Organic farming methods combine scientific knowledge of ecology and modern technology with traditional farming practices based on naturally occurring biological processes. Organic farming methods are studied in the field of agro ecology. While conventional agriculture uses synthetic pesticides and water-soluble synthetically purified fertilizers, organic farmers are restricted by regulations to using natural pesticides and fertilizers. An example of a natural pesticide is pyrethrin, which is found naturally in the Chrysanthemum flower.

Crop diversity is a distinctive characteristic of organic farming. Conventional farming focuses on mass production of one crop in one location, a practice called monoculture. The science of agro ecology has revealed the benefits of polyculture (multiple crops in the same space), which is often employed in organic farming. Planting a variety of vegetable crops supports a wider range of beneficial insects, soil microorganisms, and other factors that add up to overall farm health. Crop diversity helps environments thrive and protects species from going extinct.

CROP DIVERSITY

Organic weed management promotes weed suppression, rather than weed elimination, by enhancing crop competition and phytotoxic effects on weeds. Organic farmers integrate cultural, biological, mechanical, physical and chemical tactics to manage weeds without synthetic herbicides.Mechanical and physical weed control practices used on organic farms can be broadly grouped as.

Weed management

Organic farming relies heavily on the natural breakdown of organic matter, using techniques like green manure and composting, to replace nutrients taken from the soil by previous crops. This biological process, driven by microorganisms such as mycorrhiza, allows the natural production of nutrients in the soil throughout the growing season, and has been referred to as feeding the soil to feed the plant. Organic farming uses a variety of methods to improve soil fertility

Controlling other organisms

Organic farms total a respectable number in the US. There are approximately 12,000 dedicated farms covering over 1.5million hectares across all states. Growing slowly in number over the past decade, growth has slowed exponentially within the last 6 years. Between 2005 and 2007, the number of organic farms remained static, at a number of just below 8,500.

The land need

This may be because growing crops and food without synthetic fertilizers or pesticides is more time consuming and more expensive, which seems ironic – trading health for convenience, like much of today’s society. The industry for organic farms however, is now on the rise – 18% growth each year since 2006. This has possibly been because of people realizing that fertilized food is actually damaging their bodies. So, whilst the number of organic farms isn’t growing hugely, the people working on and companies using them is. This is a positive trend and one which can only benefit the world as a whole.Covering 40% of the US in 2007, farmland size (not just organic) has been on the decline by 1% every year since then.
