Fallow forests, which have been generated by shifting cultivation, cover large parts of the highlands of Northern Thailand. This paper presents the case study of a village, in which a particularly sustainable form of shifting cultivation was practiced until the early 1990s. Secondary forests, which regenerate on the fallow swiddens of this village were found to be surprisingly rich in tree spec...

The Five different cropping patterns such as Fallow-Fallow-Fallow (F-F-F), Sugarcane-Sugarcane-T Aman (S-S-R), Vegetables-Fallow-T (V-F-R), Fallow-Fallow-T (F-F-R) and Fallow-Mung bean- T (F-M-R) from Jessore district were investigated for carbon sequestration in soil aggreagates. Highest value of bulk density (1.53 g cm-3) was found S-S-R lowest (1.27 F-M-R. under V-F-R exhibited highest poros...

The intensification of dairying can have adverse impacts on the environment through diminished soil quality and greater loss of nutrients to water bodies. Poor soil quality can reduce the productivity and sustainability of pastoral farming systems. The effects of increased stocking rate (SR) (3, 4 and 5 cows/ha) and introducing a cut and carry system on soil, pasture and water quality were comp...

Fruit quality and productivity datasets, obtained over two seasons from 24 New Zealand persimmon orchards, were associated with a self organising map trained on the spatial coordinates and geographic region of each orchard. Using this approach, a summary representation of the geographic distribution of the orchards was obtained from the projection plane of the self organising map. By overlaying...

Plum pox, an invasive disease recently identified in Pennsylvania stone fruit orchards, is caused by the aphid-transmitted Plum pox virus (genus Potyvirus, family Potyviridae, PPV). To identify potential vectors, we described the aphid species communities and the seasonal dynamics of the dominant aphid species within Pennsylvania peach orchards. Aphids were trapped weekly in 2002 and 2003 from ...

Agriculture is the single biggest user of land and water in Morocco; however its performances are still low due to high rainfall variation and rates of soil productivity depletion. Increasing concerns about soil and environment quality degradation have raised the need to review existing tillage management systems and develop new systems for seed-bed preparation. Consequently, No-tillage is foun...

Asclepias syriaca L. is species-introduced with high potential as a source of biofuel, an important fodder crop for beekeeping, possible biologically active substances. However, the species has invasive activity and may pose threat to biodiversity natural plant communities. And also economic agroecosystems segetal species. In agricultural landscapes central Russia in various habitats dynamics s...

The effects of intercycle cover crops on Rotylenchulus reniformis population densities in pineapple were evaluated in one greenhouse and two field experiments. In the greenhouse, Crotalaria juncea, Brassica napus, and Tagetes erecta were planted for 3 months and then incorporated. These treatments were compared to weedy fallow with or without 1,3-dichloropropene (1,3-D) in three soils (Makawao ...
