Monosem has added a precision drill and 17 row cultivator with a 25cm inter-row for prevision drilling and hoeing to its range of products. The new drill now includes cereal crops such as wheat and barley.
Many trials conducted by seed companies have shown the importance and benefits of accurate seed placement, even in cereals. The use of a precision drill meets this criteria by reducing losses due to poor emergence and giving faster emergence thanks to the quality of the soil seed contact combined with the soil closure, ‘sealing’ obtained by the PRO wheel.
Regularity of the seeding depth obtained by the discs and neighbouring depth control wheel design offers regular emergence, equalising the competition between the plants and making it possible to optimize subsequent crop applications (all the plants are at the same growth stage during the treatments).
Because losses at emergence are limited, it is possible to reduce seed rates (less than 100 seeds/m²) giving a seed cost saving. In addition, more equal plant distribution combined with the lower planting densities limits the crop susceptibility to disease and lodging. This in turn reduces the use of plant protection products and facilitates organic farming, where the savings are even more marked, especially as field observations show that the quality of seed ‘sealing’ associated with the regularity of depth of sowing, limits losses when using mechanical weeding solutions.
With this sowing technique, higher yields have been achieved, which when added to the savings of seed, reduced crop applications, or adoption of organic cropping, all offer a gain on net margin.
The versatility of the MONOSEM seed distribution made it possible to test this technique without having to modify the seed drills or calibrate the seed. Only the seed discs needed changing.
The first tests were carried out using single row drills with interrows of 50 or 60 cm and making 2 successive passes, to give a final inter-row of 25 or 30 cm. This inter row was also found to be more suitable for hoeing, offering the savings of reduced use of herbicides.
To meet this requirement without requiring two successive passes, the Monoshox NG Plus M or NG Plus 4 row units can be equipped with narrow depth control wheels and hoppers with a compact rear packer unit.
This reduced inter-row also opens the way to use one drill across an even wider range of crops (eg. maize, sugar beet, oil seed rape) with the possibility to disengage alternate rows offering 9 row at 50cm or pairs of rows giving 6 rows at 75cm and even one row in three to achieve 6 Twin-rows at 25cm on 75 cm inter row centres.
The compact version of the Multicrop range has been developed to adapt to inter-rows from 18 to 65 cm for cereals and some market gardening crops. This new element has a narrow front wheel of 380x65mm, with quick and positive working depth adjustment with a pin control handle.
The element can receive up to 3 tools (shoes, shovels, ‘L’ blades). The new very short element design positions these tools closer to the wheel, increasing the precision of hoeing thanks to perfect ground tracking and short offset.
The ‘box frame’ parallel linkage with metal bushed arms, a feature of design coming from the Multicrop range, ensure a high strength of element allowing intensive use over large areas. The element is also able to support numerous complimentary equipment (rotary finger weeder, rear comb, disc ridgers etc).
The Multicrop Compact unit can accommodate seedling discs as well as hydraulic lift components that are compatible with GPS section control auto lift, to reduce crop damage at the headlands.
