The succession of events after revegetation has rarely been studied. A plant consortium with a good initial development may come to be inadequate later, resulting in exposed soil, susceptible to the weathering forces. The objective of this study was to monitor characteristics associated with...

Earthworms are important soil animals in grassland ecosystems and are considered to be important to soil quality. The overall impact of earthworms on soil properties and plant diversity, however, depends on earthworm species, functional group and the type of ecosystem. The primary purpose of this...

Three experiments were carried out at the Goat and Rabbit Research Centre and on farms in Bavi, Ha Tay province of North Vietnam. In the first experiment, biomass production of Tithonia diversifolia (Wild Sunflower) and the effect on soil fertility was studied in a complete random plot design with...

The protective effect of windthrow-related wooden structure elements such as living trees, snags, stumps, boles, and mounds against rockfall and snow avalanches was studied after windthrow in a steep mountain protection forest in the Swiss Alps. The study site near Disentis was a 2.49 ha uncleared...

Soil conservation trials were conducted on an Aquic Paleudult soil at Bajo Seco, Distrito Federal, Venezuela, to examine the effectiveness of different vegetation barriers on slopes of 15-20% cultivated with carrot. Barrier plant species included: vetiver grass (Vetiveria zizanioides), Guatemala...

A study was conducted to evaluate the experiences gained through establishment of contour hedgerow farming systems in the jhum fields of Nagaland and Arunachal Pradesh, India. Four sloping agricultural land technology (SALT) were used in the area: SALT-I-composed of traditional crop systems with...

Field studies on planting methods for Cassia siamea in order to increase moisture conservation were carried out during 1993-95 in Orissa. The methods tested were the continuous contour V-ditch, the crescent, staggered trenches, and the normal pit method (control), Seedlings were planted in July...

Field tests were conducted of 4 planting methods (continuous contour V-ditch planting, crescent planting, staggered trench planting, and the normal pit planting method) in 1993-95 at Sidingi and Nabaguda villages, Phulbani District, Orissa, on land with a slope of 4-6%, with acidic soil (pH 5.3)....

The contribution of Cassia siamea hedgerows and mulch to erosion control was evaluated on a 14% slope of a Lixisol/Alfisol at Machakos, Kenya from 1989 to 1992. The four treatments, in 400 m² runoff-plots were: hedgerows with prunings applied as mulch to the crop, hedgerows and crops with prunings...

A study was conducted over 6 years on a sloping (15-20%) Typic Paleudult to evaluate the soil and water conservation potential of contour hedgerows of Inga edulis. The experiment involved two treatments: (a) sole crops of rice and cowpea (Vigna unguiculata) in annual rotation and (b) intercropping...
