Effects of No-tillage Fallow as Compared to Conventional Tillage in a Wheat-fallow System

The fallow and the non-fallow states in swidden agriculture: a stochastic analysis

At any point in time, a cleared parcel of forest land (CPFL) used for swidden agriculture exists in either the fallow or in the non-fallow state. Further, the practice of swidden agriculture requires one to operate in an environment of uncertainty. These two points notwithstanding, there are virtually no probabilistic models of swidden agriculture that explicitly account for the above dichotomy...

Fallow deer impacts on Wakatipu beech forest

This study uses data from forty-nine 20 m × 20 m permanent plots measured in 1976, 1982, 1989 and 1997-2002 in Wakatipu Forest, western Otago. We relate changes in red (Nothofagus fusca), silver (Nothofagus menziesii) and mountain beech (Nothofagus solandri var. cliffortioides) forest vegetation to the presence of fallow deer (Dama dama). Vegetation composition is likely to have been altered pr...

Bioaccumulation of Pcdd/dfs and Dioxin-like Pcbs in the Soil Food Web of Fallow Rice Fields in Japan

Abstract The objective of this study is to investigate the concentration of PCDD/DFs and dioxin-like PCBs in a fallow soil ecosystem and to reveal its bioaccumulation mechanism. Soil, earthworm and lesser Japanese mole (Mogera imaizumi) samples were collected in the two fallow rice fields in Kanagawa Prefecture, Japan. The TEQ concentrations of dioxins in soils (organic carbon base) and earthwo...

Relationship of nematode communities to human demographics and environment in agricultural fields and fallow lands in Senegal

One hundred and nine soil samples were collected in 69 different localities along two transects, one North– South, about 900 km in length, and the other East–West (750 km in length), across Senegal and Gambia. The first transect followed a rainfall gradient and the second a human density gradient. The relationship between carbon content, C/N ratio and soil type on the abundance and species dist...
