Abstract
Parent material of the Black Solonetz Duagh silt loam was incubated after mixing with the equivalent of 20 yr production of bromegrass (Bromus inermis Leyss) that had been grown on unfertilized Duagh silt loam, fertilized Duagh silt loam, and unfertilized Eluviated Black Chernozemic Malmo silt loam. The impact of the amendments on soil properties was measured by suitable laboratory analyses and by growing barley seedlings (Hordeum vulgare L.). The unfertilized Duagh bromegrass had minimal effect on the chemical and physical properties of the parent material. Unfertilized Malmo and fertilized Duagh bromegrass generally had similar effects and imparted similar organic matter (OM) characteristics to the Duagh parent material. They lowered the breaking strength of the soil and enhanced the yields of the barley seedlings and the N, Na, Ca, and K uptake by the barley seedlings. The incorporation of the unfertilized Malmo and the fertilized Duagh bromegrass caused an 8- to 14-fold increase in the infiltration rate and caused a mobilization of alkaline earth cations. With leaching in the presence of certain forms of OM, the solubilized cations displaced Na from the exchange complex and lowered the exchangeable sodium percentage (ESP) to the level found in Chernozemic soils. Thus, the composition and amount of the plant material added to the soil may influence the development of a Solonetzic or Chernozemic soil profile from the same parent material.
