What is conservation tillage?
Conservation tillage is a system of tillage in which organic residues are not inverted into the soil such that they remain on the surface as a protective cover against erosion and evaporation losses of soil moisture. If stubbles from the protective cover on surface, it is usually referred as stubble mulch tillage.
What is the purpose of tillage?
The aim of the tillage is to produce as good a soil condition or tilth as possible for crop establishment and initial shoot and root development. When soil is brought to such a condition ideal for crop growth, it is called seed-bed and is said to be in good tilth.
What is a sweep cultivator?

What is stubble mulch?
If stubbles from the protective cover on surface, it is usually referred as stubble mulch tillage. The residues left on the soil surface interfere with seed-bed preparation and sowing operations. Objective: To conserve soil from erosion along with water (moisture).
What is minimum tillage?
Minimum tillage refers to growing a crop using only that tillage needed for placing the seed at proper depth and then covering them. Thus minimum tillage aimed that reducing tillage to the minimum necessary for ensuring a good seed-bed, rapid germination, satisfactory stands and favorable growing condition.
What is tillage operation?
a. The tillage operation which constitutes the initial measure soil working operation. It is normally design to reduce soil strength, cover plant material and rearrange aggregates and mainly for seed bed preparation.
What Is Tillage?
We can define it as the “ physical manipulation of the soil ” to create favourable conditions for the growth of crops. Hence by practicing tillage we create good aeration and water absorbing capacity in the soil. Moreover we also destroy pest by eliminating their habitat.
What is secondary tillage?
Tillage operations that we practice after primary tillage to create proper soil tilth for seed sowing and planting are secondary tillage. They are lighter and finer operations, that we perform on the soil after primary operations.
What is tillage in farming?

How does a deep seed bed help?
It helps in obtaining deep seed bed which is suitable for variety of crops. We can add more humus and fertility to the soil by covering the vegetation. It helps in destroying and preventing weeds. We can create scope for good aeration in the soil for crop growth.
What happens after every harvest?
After every harvest there will be crop residues, soil clods, insects, pests, and compaction in soil due to roots. So to raise crops for the next season farmer must have to do something to create favourable condition in the soil for crop growth. There comes the importance of tillage. What Is Tillage?
Why is mulch important?

What is the primary tool used by farmers?
Since the mid-19th century, most farmers used the moldboard plow as their primary tool. This implement overturned the soil and buried the previous crop’s residue, leaving only fragments covering less than 15 percent of the soil surface. In the last 50 years, farmers across the country began using less aggressive primary tillage tools such as ...
What is tandem disking?
Tandem disking is a common secondary tillage practice used in the spring to prepare a smooth seedbed and incorporate broadcasted fertilizers. However, if used as a primary tillage tool, tandem disking can have the same potential downside as vertical tillage, as crop residue becomes prone to blowing or washing away.
Why are there basketball clods in Minnesota?
In 2011, basketball-sized and larger clods were seen across western Minnesota due to tillage during extremely dry soil conditions. Two to three tillage passes were needed in the spring to create an acceptable seedbed.
How deep is moldboard plowing?
Moldboard plowing inverts the soil to a depth of 8 to 12 inches, which is measured to the moldboard share’s bottom edge (Figure 1). Typically, moldboard plowing is conducted in the fall, requiring farmers to make one or two secondary tillage passes with a field cultivator or tandem disk before planting.
