A paddy field is a flooded parcel of arable land used for growing rice and other semiaquatic crops. Rice can also be grown in dry-fields, but from the twentieth century paddy field agriculture became the dominant form of growing rice.
They are also found in other rice-growing regions such as Piedmont Italythe Camargue France the Artibonite Valley Haitithe Sacramento Valley of California, and the remains of rice paddies still define much of landscape of the Carolina Lowcountry US.
Paddy fields can be built adjacent to otherwise natural areas such as rivers or marshes. They can be constructed, often on steep hillsides with much labor and materials. The fields require large quantities of water for irrigation. Flooding provides water essential to the growth of the crop.
Water also provides a favorable environment for the rice strains being grown as well as discouraging the growth of many species of weeds.
The water buffalo is one of the most important working animals adapted for life in wetlands so they are extensively used in paddy fields. Growing rice has an adverse environmental impact because of the large quantities of methane gas it generates. World methane production due to paddy fields has been estimated to be in the range of 50 to million tonnes per annum.
However, recent studies have shown that methane can be significantly reduced while also boosting crop yield by draining the paddies allowing the soil to aerate, which interrupts methane production. At Caoxieshan, a site of the Neolithic Majiabang culturearchaeologists excavated paddy fields .
Some archaeologists claim that Caoxieshan may date to B. There is archaeological evidence that unhusked rice was stored for the military and for burial with the deceased from the Neolithic period to the Han Dynasty in China.
A pit-house at the Daecheon-ni site yielded carbonized rice grains and radiocarbon dates indicating that rice cultivation in dry-fields may have begun as early as the Middle Jeulmun Pottery Period c. The paddy field feature was found next to a pit-house that is dated to the latter part of the Early Mumun Pottery Period c.
KUM has conducted excavations that have revealed similarly dated paddy field features at Yaeum-dong and Okhyeon in modern-day Ulsan . The earliest Mumun features were usually located in low-lying narrow gullies that were naturally swampy and fed by the local stream system.
We can grasp some paddy-field farming techniques of the Middle Mumun c. However, iron tools for paddy-field farming were not introduced until sometime after B. The spatial scale of paddy-fields increased with the regular use of iron tools in the Three Kingdoms of Korea Period c.
The first paddy fields in Japan date to the Early Yayoi period .
The Early Yayoi has been re-dated and thus it appears that wet-field agriculture developed at approximately the same time as in the Korean peninsula. In the Philippines, the use of rice paddies can be traced to prehistoric times, as evidenced in the names of towns such as Pila, Lagunawhose name can be traced to the straight mounds of dirt that form the boundaries of the rice paddy, or "Pilapil.
Bundesarchiv BildChina, Reisfelder bei Peking. Rice appears to have been used by the Early Neolithic populations of Lijiacun and Yunchanyan in China.
One was the use of cast iron tools and beasts of burden to pull plows, and the other was the large-scale harnessing of rivers and development of water conservation projects.
The engineer Sunshu Ao of the 6th century BC and Ximen Bao of the 5th century BC are two of the oldest hydraulic engineers from China, and their works were focused upon improving irrigation systems.
During the Eastern Jin and the Northern and Southern Dynastiesland-use became more intensive and efficient, rice was grown twice a year and cattle began to be used for plowing and fertilization. Such large-scale internal migration was possible due to introduction of quick-ripening strains of rice from Vietnam suitable for multi-cropping.
India India has the largest paddy output in the world and also the second largest exporter of rice in the world. Paddy fields are common sight throughout India, be they northern gangetic plain or southern peninsular plateau. The former cultivation is dependent on irrigation while latter depends on Monsoon.
The paddy cultivation plays a major role in socio-cultural life of rural India.A paddy field is a flooded parcel of arable land used for growing semiaquatic rice.
Paddy cultivation should not be confused with cultivation of deepwater rice, which is grown in flooded conditions with water more than 50 cm (20 in) deep for at least a month.
'Wet-field' is just another term for paddy that is used by archaeologists. There are two methods of growing rice using dry-fields and wet-fields (paddies). All the stuff from the rice article that mention really early dates, including Yunchanyan at BC etc, refers to rice grown in dry-fields rather than paddies.
Talk:Paddy field Jump to History of Paddy Field Farming (globally speaking) Cultures with unique approaches to Paddy Field Farming or cultural traits arising from it; which might mean moving some materiel from the country-specific sections and onto the main body. Paddy, also called rice paddy, small, level, flooded field used to cultivate rice in southern and eastern Asia.
Wet-rice cultivation is the most prevalent method of farming in the Far East, where it utilizes a small fraction of the total land yet feeds the majority of the rural population. A paddy field is a flooded parcel of arable land used for growing semiaquatic rice.
Paddy cultivation should not be confused with cultivation of deepwater rice, which is grown in flooded conditions with water more than 50 cm (20 in) deep for at least a month. Preparing the paddy-field for planting is an interesting (and mucky) business. An elaborate network of channels and pipelines brings the water to flood the paddy-field and form a deep layer of soft mud, which has to be levelled so that all parts get the same treatment.
