Products / DPL Subsoiler
Growing of oilseed / rapeseed usually is a profitable crop even if yield is just average. Soil richness, seedbed preparation, selection of seed, fertilizers, plants protection agents are key factors impacting the end quality of crop and its yield. Every step from fields preparation to harvest means costs, the lower – the better (if yield stays the same or insignificantly lower). “Laumetris” concentrates on reducing costs of seedbed preparation and sowing process also on establishing of optimal conditions for seeds germination. All is set through Strip Till technology, which usually does not improve income / yield but highly reduces costs – improved profit astonishes every conventional farmer.
Every conventional farmer when harvest season is over hurries to ploughing or harrowing one‘s fields. With harrowing farmer mixes plant residues with soil and stimulates dropped seeds to germinate which leads to inevitable second harrowing before sowing of winter rapeseed. Ploughing on the other hand puts residues deep under the soil and, if moisture conditions are great, farmer may directly go with a sowing machinery. If moisture level is down additional cultivation or compaction with rollers is necessary. Both technologies: harrowing and ploughing, end up on few drives before sowing and another negative side effect is mineralization of stubble, which always extracts nitrogen from soil.
The first “Laumetris” subsoilers were manufactured back in the beginning of new millennium, over the time: countless tests and improvements, gained experience, DPL subsoiler offers the highest quality aggregate for soil loosening and winter rapeseed sowing. The key feature is Strip Till type drilling in width of 50 cm. Average costs per hectare of such drill is 38-45 Eur/ha (1). Conventional way with disc or tine harrowing comes at 68-75 Eur/ha (2) or 75% more than with DPL subsoiler and its Strip Till technology. Conventional farming with ploughing costs even more roughly 74-87 Eur/ha (3) and more or less is 110% more expensive.
(1) Costs of drilling per hectare was calculated according to methodology of Lithuanian institute of agrarian economics – “Prices of mechanized agricultural services 2017“. Key factors were field size – 20 ha, tractor‘s power – 300 HP, tractor‘s value – 175 000 Eur, DPL-3 value – 27 000 Eur. Estimated costs were: machinery renewal costs – 12,19 Eur/ha; maintenance and service – 8,9 eur/ha; fuel and oil costs – 10,36 Eur/ha; labour costs – 1,94 Eur/ha. In total with additional 5% - 35,06 Eur/ha costs.
