A cultivator is a piece of agricultural equipment used for secondary tillage, which involves preparing the soil for planting after primary tillage has been completed.
Key Facts
- Soil Stirring and Aeration: Cultivators are used to stir and aerate the soil, creating a loose and well-aerated seedbed for planting.
- Weed Control: Cultivators help in destroying weeds by disturbing the top layer of soil, uprooting the weeds and burying their leaves, disrupting their photosynthesis.
- Breaking up Soil Clumps: Cultivators are effective in breaking up clumps of soil, creating a finer and more even soil texture.
- Access to Nutrients: By loosening the top layer of soil, cultivators make it easier for plants to grow roots and access nutrients.
- Different Types: Cultivators can be toothed or rotary. Toothed cultivators have teeth or shanks that pierce the soil linearly, while rotary cultivators use rotating disks or teeth to achieve similar results.
- Size and Power: Cultivators can vary in size and shape, ranging from small garden tools to large industrial machines. They can be self-propelled or attached to tractors.
- Primary and Secondary Tillage: Cultivators can be used for both primary and secondary tillage. Primary tillage prepares the soil before planting, while secondary tillage is done after the crop has started growing.
- Row Crop Cultivators: Row crop cultivators are specifically designed for weed control between rows of established crops. They have blades that cut weeds near the base of the crop and turn over the soil.
- Garden Cultivators: Small cultivators are used in household gardens and small commercial gardens for both primary and secondary tillage. They can prepare a smooth seedbed and control weeds.
- Historical Significance: Cultivators have been used since ancient times, with early forms including hoes and mattocks for weed control.
Functions of Cultivators
Cultivators are used to stir the soil around a crop as it matures to promote growth and destroy weeds. Additionally, they are employed for the following purposes:
Breaking up Soil Clumps
Cultivators break up clumps of soil, resulting in a finer and more even soil texture.
Improved Soil Structure and Aeration
By breaking up compacted soil, cultivators improve soil structure and aeration. This allows for better water infiltration and drainage, aiding plant growth and disease resistance.
Weed Control
Cultivators help control weeds by disturbing the top layer of soil, uprooting weeds, and burying their leaves, thereby disrupting their photosynthesis.
Access to Nutrients
Cultivators loosen the top layer of soil, making it easier for plants to grow roots and access nutrients.
Types of Cultivators
Cultivators can be categorized into two main types:
Toothed Cultivators
These cultivators have teeth or shanks that pierce the soil linearly.
Rotary Cultivators
Rotary cultivators utilize rotating disks or teeth to achieve similar results as toothed cultivators.
Size and Power of Cultivators
Cultivators vary in size and shape, ranging from small garden tools to large industrial machines. They can be self-propelled or attached to tractors.
Primary and Secondary Tillage
Cultivators can be used for both primary and secondary tillage. Primary tillage involves preparing the soil before planting, while secondary tillage is done after the crop has started growing.
Row Crop Cultivators
Row crop cultivators are specifically designed for weed control between rows of established crops. They have blades that cut weeds near the base of the crop and turn over the soil.
Garden Cultivators
Small cultivators are used in household gardens and small commercial gardens for both primary and secondary tillage. They can prepare a smooth seedbed and control weeds.
Historical Significance of Cultivators
Cultivators have been used since ancient times, with early forms including hoes and mattocks for weed control.
Conclusion
Cultivators are essential agricultural tools used to prepare soil, control weeds, and promote crop growth. They come in various sizes and types to suit different farming needs and are crucial for maintaining healthy and productive soil conditions.

What are row crop cultivators specifically designed for?
Row crop cultivators are specifically designed for weed control between rows of established crops. They have blades that cut weeds near the base of the crop and turn over the soil.
What are the benefits of using cultivators in agriculture?
Cultivators provide several benefits, including improved soil structure and aeration, weed control, time and labor savings, soil conservation, and cost savings.
How have cultivators evolved over time?
Cultivators have been used since ancient times, with early forms including hoes and mattocks for weed control. Over time, cultivators have evolved to include more advanced designs, such as toothed and rotary cultivators, which are more efficient and effective in preparing soil and controlling weeds.
What are some factors to consider when choosing a cultivator?
When choosing a cultivator, factors to consider include the size and type of crop, soil conditions, the desired level of weed control, and the availability of power sources.
