Historical Approach
Recorded in history that since thousands of years ago the processing of land has been done by a group of humans in order to increase agricultural production. Veterinary is used to plow the land since 7000 years ago. In archaeological findings and ancient writings it is known that there is an opinion that plowing the soil may increase soil fertility.
In the scientific writings of the nineteenth century, the subject of cultivation of the land seems to have begun from this view. Many questions arise in how the fertility of the soil can be improved. At least in the first half century of the twentieth century, there are two main approaches in studies of soil cultivation. The first group of scientists began by questioning what soil conditions are suitable for plant growth. While the second group is concerned about the best way to cultivate the land. The first group received answers, among others, that soil treatment can improve the availability of water and air in the soil; while the second group found the answer that deep piracy could yield better results than superficial piracy. These two opinions have their own weaknesses. In the mid-20th century attempts were made to combine these two approaches by studying the causal relationships of soil cultivation and crop production.
It is well known that soil treatment can alter and / or improve soil structure and eradicate weeds. Improved soil structure with soil processing is thought to have a good effect on plant growth, although the opinion is difficult to prove because it only looks at the physical aspects of the soil alone. It is certain that eradicating weeds will provide benefits for plant growth.
Subsequent developments indicate that research on soil treatment is divided into two streams, ie streams that emphasize weed and flow controls that emphasize improved soil structure. Regardless of whether or not there is any effect of soil cultivation on crop production, soil processing remains to be done by farmers at least to facilitate subsequent work.
