This paper deals with the issue of soil compaction during timber harvesting operations on cutting areas.
Soil compaction was assessed following the logging operation in Darabkola forest area by meas...
The effect of the soil compaction on the contents of alfalfa root reserve nutrients in relation to the stand density and the amount of root biomass
alfalfa soil density root reserve nutriet
2015/1/30
The reserve root nutrients influence the overwintering, regrowth, yield, and persistence of alfalfa plants. The total amount of the root reserves is considered more important than their concentration....
Long-term rice-based cropping system effects on near-surface soil compaction
Bulk Density Crop Rotation Soil Organic Matter Tillage
2013/3/4
Irrigated rice (Oryza sativa L.) production is as-sociated with frequent cycling between anaero-bic and aerobic conditions, which can lead to a greater rate of soil organic matter (SOM) de-composition...
Effects of Soil Compaction by Tractor Traffic on reclaimed soil in Isahaya Bay
reclaimed field of Isahaya Bay soil compaction
2010/12/3
At a reclaimed field of Isahaya Bay, a vehicle running test was conducted using tractors, and the penetration resistance (cone index) of soil before and after the running was compared. From this resul...
