Row culture
Sugar beet field about three weeks before row closure as an example of a series of cultural
As a row crop are crops referred where the sum of distances in the Sähreihe 40 to 70 cm. Examples include sugar beets , corn and potatoes.
Reasons for row crops
Until a few years ago, harvesting technology made it imperative to plant some crops in rows. There were maize choppers only with row-dependent harvesting attachments. Mowing in a different direction than that of the sown rows resulted in high losses in picking up. In beet lifters narrow row spacings lead to clogging of the digging units.
advantages
- A chopping machine can be used here.
- In the case of maize, the concentration of the plants enables targeted placement of the underfoot manure in a simple manner.
disadvantage
- Due to the large distance between the plants between the rows, the ungrown area is large and therefore also the area of attack for soil erosion by wind or water (thunderstorm rains).
- The closely spaced plants compete for nutrients, light and water, while these factors are available in abundance in the space between the rows.
- The incidence of light in the space between the rows enables the weeds to unfold.
Alternatives and solution concepts
- Only part of the soil is tilled through strip milling. The existing growth inhibits erosion.
- Thanks to the row-independent maize chopper attachments , maize can be sown closely , i.e. with row spacings of 30 cm.
- In the case of ploughless cultivation ( mulch sowing ), some of the harvest residues remain on the ground, which also reduces erosion.
