primary tillage refers to tillage after harvesting or on virgin piece of land where soil is inverted and plant residues and sometimes manure/ fertilizer is added. On the other hand, secondary tillage is done after primary tillage and it involves breaking the soil particles into smaller pieces and sometimes includes formation of rows for planting.
primary tillage is initial breaking up of soil to a depth of 15-30 cm while secondary tillage is the final cultivation of soil to a depth of less than 15 cm

Minimum tillage which is a soil tillage to approximately depth of 10 cm by means of cultivars and reduced tillage which is also includes deeper cultivation but not to the plough depth (Davies, et al., 2006).

conservation tillage
With conventional tillage (complete turning over of the soil), the bare soil is exposed to the erosive action of water, which, in many areas is the major route of soil loss. Under conservation tillage, the crop residue buffers the raindrops' energy, so water has less erosive force when it reaches the soil. This protection by residue, along with the rougher surface provided by the residue facilitates infiltration and decreases runoff -- runoff that carries soil and nutrients with it. In addition, macropores, which are the major route for water movement through soil, get disrupted in the surface 15-20 cm of soil by conventional tillage, but remain intact under conservation tillage. Improved macropore development also enhances water infiltration and decreases water runoff. Conservation tillage thus can also conserve water and fertilizers. http://people.oregonstate.edu/~muirp/constill.htm
The objective of primary tillage is to attain a reasonable depth of soft soil, incorporate crop residues, kill weeds, and to aerate the soil. Secondary tillage is any subsequent tillage, to incorporate fertilizers, reduce the soil to a finer tilth, level the surface, or control weeds.
i have no idea soo sorry
Secondary tillage is any tilling don after primary tillage and is undertaken forreducing ped size,weed control,incorporation of fertilizers,puddling andleveling soil surface.

Because primary tillage usually leaves the soil too rough, uneven, or even "chunky". Mechanical planting systems usually require the field surface to be somewhat level in order to give good seed-to-soil contact.

Jethro Tull was father of tillage.
tillage is which you use a tool to make the soil good
Some fields are for grazing , others are for tillage to sow new crops.

Leon Walter Tillage lived in Raleigh, North Carolina.
Tillage of the land have been lately introduced with very beneficial results.
