A field cultivator, in the simplest of terms, is a basic farm tool used to perform secondary tillage. Those with small or large acres of land use it to stir and pulverize the soil. This is mostly done before planting to give some air to the soil and to smoothen and stage the seedbed. On the other hand the field cultivator may be used, when crops are growing, to keep turning the soil over and over killing weeds in the process.
The cultivator contains blades normally referred to as cultivator teeth or shanks. These blades are used to disturb the soil in careful patterns to uproot weeds, burry their leaves and stop them from photosynthesizing. The field cultivator has come across as the best tool for weed removal compared to the chisel plow or the harrow.
The field cultivator does not dig deep into the soil but only causes a disturbance to the top soil next to the plants growing. This gives it the ability to uproot only the weeds leaving the crops intact. For this reason, the field cultivator has become a farmer favorite when they need to work only at the top of the soil and not go deeper.
The cultivator has also been voted as the best tool one can use whenever crop spacing is required. When used in field leveling just before planting, the field cultivator forms neat rows where the seeds can be planted. This ensures the plants have enough breathing space when they grow and avoid plant crowding. Crop breathability counts a lot if you want the best harvest of crops that didn’t wilt due to a struggle for nutrients with other crops.
Commercially, the field cultivator has been majorly used by big tractors to till large acres of land. The cultivators used work at precise and exact depth levels ensuring the tractors don’t use much shank power to operate them. This makes work easy and on a bigger picture helps in saving fuel usage and cost. The modern day field cultivator is also further modified to include a depth control point to adjust the depth levels with respect to the till requirements.
The earlier forms of the field cultivator were animal or human operated; they further evolved to the tractor pulled ones thanks to modern day technology. Field cultivators since then have been the solution to weed control via soil scratching. However the use of herbicides for weed control was also formulated as an alternative to use of the cultivator.
Herbicides work well in killing weeds but with side effects in the long-run. This may include high chemical content in the plants upon harvest or wilting of crops due to high toxins in the herbicides. Furthermore, the herbicides may lose their pride in these modern days when everyone is going organic. Organic crops are said to be chemical-free right from planting all the way to harvesting. And of course the weeds must be controlled for better yields; and what better way to do that than to use the field cultivator.
