In soils from black spruce ( Picea mariana [Mill.] B.S.P.) communities, low organic matter quality (e.g. low %N, high C:N, high lignin, high lignin:N, low pH, low extractable
We hypothesized that manure-derived organic matter ®rst enters the soil primarily as particulate material, and during decomposition is transformed within the macro- aggregate
In this study the objectives were to (1) evaluate the effect of 12 years of 10 no-till cropping systems on soil organic matter content and quality, as determined for example
The large proportion of medium pores, able to supply water to crops, was favored by the following conditions: high production of crop residues, high content of soil organic matter,
The dif- ferent tendency towards sealing of the treatments with equal degrees of cover on the Luvic Phaeozem was caused through increased organic matter content at the soil surface
Litter was not in- corporated into deep soil layers (>20 cm) and C inputs from roots were small because only 24% of the total root biomass was located below 20 cm depth.. This
On the basis of increased soil organic matter content, enlarged soil microbial biomass pool and greater soil N availability, agrisilvicultural systems have been found to be
Relationships between soil characteristics, various forms of soil organic matter, microbial biomass and the structure of phytoparasitic nematode populations were investigated in
