Triangular seed
As Dreieckssaat a method is called, the same room for growth is in the crop by means of a planting in triangles in all directions. In kitchen gardens, this planting method is often used for vegetables.
advantages
The even distribution of stand space has many positive effects. The result is a more even use of the nutrients present in the soil and a better use of sunlight and water. The greater distance in the row compared to conventional cultivation results in better ventilation of the stand and therefore fewer problems with pests. Typical disadvantages of row crops such as erosion between the plant rows can be greatly reduced. With consistent, correctly executed triangular sowing, the plant can be chopped from four sides, each diagonally to the usual direction of cultivation .
By chopping with conventional chipping machines in the longitudinal and transverse direction, 95% of the soil surface can be worked. In a two-year trial, the rate of control could be increased by 20% to 78%. In view of the demands for a reduction in plant protection requirements and problems with combating some weeds, such a development is to be welcomed.
Parallel seeds
Parallel sowing is comparable to triangular sowing, but here the useful plants are arranged parallel to the usual direction of cultivation.
Row narrowing as a compromise
With row sowing an attempt is made to achieve the advantages of triangular sowing to a large extent with less technical effort at the same time. In practice, especially with maize, there are some approaches to work with half the row spacing of 37.5 cm instead of the usual 75 cm. The more even arrangement of plants makes it easier to create tramlines according to the existing maintenance technology. Technically, however, there are some problems: The fertilizer tape is not so concentrated on the plants. The double number of sowing units increases the weight significantly. Due to the closer spacing of the units, the drive wheels have to be moved. In addition, the space on the side is reduced, so that, depending on the machine type, residual emptying, maintenance or the possibility of evading obstacles in the seedbed are impaired.
developments
With the GEOseed technology from Kverneland , it is possible to assign a GPS position to each individual seed . Thus, in addition to parallel and triangular sowing, it is also easy to create maize labyrinths or advertising logos.
The Institute for Agricultural Engineering at the University of Bonn , together with the agricultural engineering industry, is confident that the process of creating square bonds in sugar beet will be ready for practical use by 2015.
