The primaAgen Bola Terpercayary goal of treatment is to create a land most suitable soil conditions for plant growth with efforts seminimun possible. For this purpose is often achieved by applying a cut and try a good way to expand or develop land treatment method or equipment design to improve existing soil processing .
In situations like this there is much knowledge ( knowledge ) about the treatment of the soil making it possible to predict the cost and processing results in a clear and efficient land . Knowledge is not easy but must be owned ( analysis). Similarly, the complex problems faced in the analysis of various disciplines should be involved more ( systematic ) . With this method could be developed to predict the type of process can occur or not , and can even predict information about the design process quantitatively ( prediction ) . Has published numerous research articles on soil processing tool , but in general the article is limited to one or a few types of devices and operating conditions of the land is limited to a few only.
Specific purpose of land treatment are as follows ( Kepner , et al , 1972 ) :
Creates soil structure required for seedbed or place sprouted seeds . Compact soil to be treated accelerating infiltration loose ah, better able to withstand rainfall improve aeration and facilitate the development of roots .
Increase the speed of infiltration will reduce run -off and reduce the risk of erosion .
Inhibit or kill plants attacker.
Embedding vegetation or rubbish which is located on the ground into the soil , so adding soil fertility.
Kill insects, larvae , or eggs of insects through changes of residence and the scorching sun .
Tillage is not only a leisure activity to produce crops, but also in connection with other activities such as seed dispersal ( planting seeds ) , fertilizer, crop protection and harvesting . This relation is very close to the purpose to be achieved in the treatment of soil is inseparable from the success of other activities. Tillage influence propagation and planting seeds. Tillage can also be done simultaneously with the adoption and were seen as a method of weed control .
Related to the history of the development of soil processing in purpose and method of soil treatment followed by developments in equipment design, both in terms of materials or design tools. Much evidence suggests that light wooden plows were used on a large scale in the area of the Euphrates and Nile Rivers around the year 3000 BC even be used as a driving force / pull farming equipment, prepare the soil for planting Barley, Wheat and other crops that were popular in that era . The plow used at that time is not on wheels or plows singkal used to turn the soil and make Furrow . Most of the equipment is not functioning break Obat Pembesar Penis Vimaxground and to cover the seed . Example plow made of wood from Egypt are shown in Figure 1 .
Figure 1 . Ancient wooden plow in Thebes , Egypt in 300 B.C.
More than 2000 years ago found a plow made of steel produced in Honan north China . At the beginning of this tool in the form of a small device that is pulled by hand with a V-shaped metal plate connected wood or digandengkan with a knife and holding . During the first century BC , the buffalo used to haul soil processing equipment . Then successively developed a tool called the triple - shared Plow , Plow -and- Sow and rakes .
The plow was used also in India for thousands of years. Antiquated equipment and moldboard without wheels made of hard wood ( hardwood wedge -shaped blocks ) are pulled by ox ( bullock ) . With this tool into the ground just broken but not flipped form clods , and the first treatment is then followed by a crushing ” clod ” and leveling the ground with a stick barupa shaped rectangle drawn by oxen .
Steel plow blade appeared in Rome in about 2000 years ago as a knife Coulter . At that time, still has not found a function singkal plow land flips . On heavy soils and hard , steel plow blade is pulled by teams of oxen ( oxen ) . There are reports stating that the plow is equipped with wheels found in northern Italy around the year 100 AD
A more complete tool , consisting of wheels, cutters and moldboard Coulter used in Europe in 1500 AD as shown in Figure 2 . This equipment can be used to turn the soil and make Furrow and kasuran seed.
Figure 2 . Two-wheeled plows with Coulter and moldboard , was found in the 16th century in Europe
In about 1830, John Deere steel plow tempted to expand with a knife and a moldboard to oJudi Bola Online vercome the problem processing organic soils in America. Animal -drawn equipment began to shrink amount since the discovery of steam powered tractors around 1860.
2 . SISTEMATIKA AND SOIL TREATMENT PROCESS
Tools and Component Operations
Tillage equipment and wheel mounted on the tractor , harvester , trailer and so presents a number of shapes and dimensions. This description should be limited only to the components relating to land directly, and as the plow ( bottom- Plow ) , Chisel . and other tools , including the wheels. The components that are commonly referred to as operational components ( operating tools) . Furthermore , this description will only be limited to operating components that work with constant speed on a horizontal path and is not affected by other operational components work around it.
Land Processing and loading
Soil treatment process involving factors such as tools, equipment and land regulators will look for the device to work on the ground. This process consists of moving and style on land as a result of the work tool at the time. On the ground processing activities there are two processes / events that take place simultaneously or separately namely , cutting / cultivation of land and the loading on the ground. The cultivation process is the process relating to the fragmentation / separation of a mass of soil into soil aggregates smaller jobs such as those generated from piracy , penggaruan and so on . The process of loading is the process of relating Pulau Pramukato soil properties such as soil strength upward ( soil strength ) as a result of wheel crossings , land rollers and so on .
