The change of soil physical quality depending on long-term land use types in a semi-arid ecosystem.

In agricultural areas, soil physical quality controls critical properites for plant growth, such as aeration, soil water, and strength. This study investigated the impacts of different long-term land use types (LUTs) (natural pasture (control), kiwi fruit, cherry laurel, forage crops, soybean, and maize) on soil physical properties, such as structure stability index (SSI), bulk density (ρ), aeration capacity (AC), and Dexter's index (S-index). The long-term LUTs significantly affected all the examined soil properties (p < 0.

Changes in some soil properties at different incubation periods after tobacco waste application.

In this study changes in organic carbon (OC), basal soil respiration (BSR), nitrate nitrogen (NO3-N), electrical conductivity (EC) and aggregate stability (AS) of a clay loam soil due to tobacco waste (TOW) application were monitored for 240 days. After incorporating 5% TOW into soil according to oven dry weight basis, soil samples were incubated at field capacity for 20, 40, 80, 140 and 240 days under a greenhouse condition. TOW application significantly increased all soil properties over the control treatment Soil OC and AS values had significant positive correlations each other and with the other soil properties.
