Cultivating..The JD is a beuty in my hubbies eyes!! 1. IMPORTANCE OF SOIL:

Soil, which is of vital importance for all living things on earth, is formed by the continuous erosion of the rock layer (lithosphere), which forms the crust of the earth, as a result of climatic and geological events. In the soil formed in this way, there are sand, clay, loam, lime, plant and living residues of different sizes as decomposition and coalescence products.




In order to be successful in field agriculture, first of all, it is necessary to prepare a good seed bed suitable for planting and tempering. Good seedbed preparation is also possible with a timely and conscious soil cultivation in accordance with the technique by using agricultural tools and machinery suitable for the soil structure.


We can define tillage as loosening, crumbling and mixing with any means to plant seeds, to grow plants, to make the soil suitable and to maintain this condition.


Tillage methods vary according to soil type, tillage time, crop rotation, type of plant planted, climatic conditions and mechanization level at hand.


Purposes of tillage:

a) To prepare the seed bed,


b) To control weeds,


c) Plant residues on the soil surface, stubble and barn


to bury the manure,


d) To control water and wind erosion.




Different tools and machines have been developed to work the agricultural lands for the necessary purposes. It is possible to classify the tillage tools according to the priority of use, the way of working and their effects on the soil.


3.1. Classification of Soil Tillage Tools According to the Order of Use:


First class tillage tools: plows, chisels, bottom boilers,

Tillage tools of the second class: cultivators, harrows, tillers, rollers,

Tool combinations: harrow-cultivator, harrow-roller, cultivator-tooth harrow, spring harrow-spin harrow.
