Modern corn generation tactics are being utilised that help to lessen the impact of corn crop on soil and water resources. Several of those tactics include no-tillage production, the utilization of delayed “sidedness” nitrogen fertilizer applications, delayed or postemergent herbicide applications and thus the establishment of canopy crops during or following the corn crop. In no-tillage production, the planet isn't plowed or cultivated between crops. No-tillage production reduces the potential for erosion , conserves soil moisture, and reduces the energy related to corn production. Side dress nitrogen fertilizer applications reduce the potential for nitrogen fertilizer loss by applying the fertilizer immediately before the only demand by the crop. Postemergent herbicide applications allow corn producers to use less persistent herbicides before planting the crop and their use has been greatly increased by the event of both glyphosate and glufosinate herbicide resistant corn hybrids during the last decade. The establishment of canopy crops following harvest has been promoted and is now required in some situations to attenuate runoff and plant nutrient losses from either residual amounts of fertilizer not employed by the corn crop or from animal manure applications made to the planet following harvest.
The establishment of canopy crops is usually limited by the late fall harvest of the corn crop in some areas, which leaves little season for a canopy crop, like clover or ryegrass, to become established, and it’s important to shift unwanted stones, for example with a stone burier. Alternative seeding methods like broadcasting the seed within the standing crop before harvest with a helicopter or ground based applicator are inconsistent, especially in no-till fields that are covered with the residue from the previous crop. Researchers from Cornell have announced successfully seeding cover crops through the late spring in fields that were tilled with minimal residue on the soil surface with no impact on crop yields. during this system crop seeds were broadcast on the soil surface and incorporated employing a row crop cultivator. A second study showed that this technique might be utilized in soybean production.
Other researchers have proposed to plant a standing crop in an existing crop without the necessity to perform a canopy crop seeding operation within the late spring. This tactic, often called a living mulch, are often effective but requires the suppression of the duvet crop with a herbicide at the time of planting of the standing crop to avoid undue competition with the foremost , or standing, crop, like corn. Canadian researchers have described the effective use of seeding devices which may cover crops through a standing crop of corn during a tilled seedbed. However, the device described only performs a seeding operation and isn't capable be utilized in no-till systems. Their experience demonstrated the potential utility of this in-season crop or “relay crop” as a neighborhood of corn production. Another system for performing row crop farming and seeding has been formed for minimum tillage conditions, but it lacks sort of the weather and benefits of this invention, or stone burier for sale.
