New paddy generally does not have physical properties

New paddy generally does not have physical propertiesIdeal for paddy soil . Soil percolation is still relatively high becauseplow tread layer has not been formed so that the efficient use ofwater is still low .During the formation processBatikpoker.com Judi Poker Online Uang Asli Indonesia of the rice fields , the physical properties of the soilmany changes . The process of reduction and oxidation is a process -The main processes that can lead to changes in both the nature of the mineral ,chemical , physical , and biological properties of soil . Changes in soil physical properties are also manyinfluenced by the occurrence iluviasi and / or chemical or eluviasisoil particles due to changes in drainage and siltation process .Soil cultivation in paddy fields is important for new openingsget the ideal soil physical conditions and suppress variousnegative impacts that could arise . Puddling process , as ahow specific tillage for rice soils providepositive influence in creating a suitable planting medium forrice , pressing percolation , as well as supporting the formation of a layer of treadplow .EFFECT OF LAND MANAGEMENT / puddling PHYSICAL PROPERTIES OF SOIL SAWAHTexture and clay mineral type , structure , and organic matter content determine the degree of influence of puddlingto changes in the physical properties of the soil . Puddling little effect or may not affect the nature ofphysical coarse -textured soils or soil that is easily dispersed , for example finely ground bertektur with ESP(exchangeable sodium percentage/ percent sodium exchange ) high , or is sodic soils . greatest influenceof wet processing system to the physical properties of the soil occurs in bertektur smooth , with a high clay activity , whichwhen aggregated in the dry state . Thus , to minimize the time and cost of processing are expensive ,it is important to identify which soil physical properties can or can not be manipulated by processingwet .OPPORTUNITIES AND PROBLEMS PRINTING ON VARIOUS TYPES OF RICE FIELDS NEW LAND BASEDPHYSICAL ASPECTS OF LANDUltisols and Alfisols have argillic horizon is characterized by the accumulation of clay . Ultisols and Alfisols with regimeAquic moisture are not many obstacles have to be rice fields . However, if the moisture regime is Ustikor Udik , tread plow layer will typically be formed on top of argillic horizon and this requires the establishment ofRgopoker.com Bandar Judi Poker Situs Poker Online Terpercayalong time . Percolation tread plow layer formed is usually still relatively high , especially in somethe first year since the land is used as a paddy field . To Oxisols tread plow layer formation is also tough going( Eswaran , 1985) due to the strong aggregation of power by sesqui oxide .Entisols that have the potential to be used as rice fields are Aquents , except Hydraquents which has a carrying capacity(bearing capacity) Is low . These lands are usually located on the plains and frequent tidal flooding .Sulfaquents containing pyrite which may cause the soil is very acidic when oxidized ( drained ) .Psammaquents is sandy soil with a shallow water table . Pore ​​water availability is very low , sowhen there is no supply of water , plants growing on this land will be susceptible to drought .Land Inceptisol have physical properties similar to the Entisols . Typic Tropaquents have ground water levelshallow and Aeric Tropaquepts have above ground water impermeable layer (perched water table) . Ustropeptsvery sensitive to drought . The texture will determine whether or not the land is used as a paddy field . landare almost no constraints to be rice fields , both in terms of physical and chemical properties , are Mollisols( Eswaran , 1985) . Subagyono and Agus (1994 ) based on soil survey data provide a list of soil series , subgroup( in Soil Taxonomy ) and data interpretation of soil physical properties in conjunction with the new paddy fields ( Table 8 ) .According to Eswaran (1985 ) most of the information related to Investmandiri.com Bisnis Investasi Online Sebagai Lowongan Kerja, Dan Peluang Usaha Murah the management aspects of the series presented on the levelground or phase of a soil series .More Information:Research Group Physics and Soil Conservation,
