Wpływ uproszczeń w uprawie roli na zapas nasion chwastów w erodowanej glebie lessowej [The influence of simplified on reserve of weeds in erodible loess soil]

Marian Wesołowski, Karol Bujak

Abstract


In the paper the influence of diferent simplified tillage per number and seeds botanical composition of weeds in 0-25 cm of soil layer under plants crop rotation (potato-spring barley-winter rape-winter wheat) on erodible loess soil was presented. The simplifications in soil tillage relied on replaceing ploughing by cultivation, rotary cultivator tillage or Gramoxone formula. The replaceing ploughing by cultivations or rotary cultivator tillage especially bringing in chemical tillage instead of after-harvest cultivation increasing the number of weeds seed under all plants excluding spring barley. Resource of weeds seed under all plants of crop rotation were formated mainly by short duration species, especially Chenopodium album and Viola arvensis as well as Stellaria media (potato, barley, wheat) and Veronica persica (wheat). It was proven that the number of weeds seed in 0-25 cm of soil layer on erodible loess slope depended from plant species more than the way of soil tillage.
