“…Table 1 showed that TN displayed similar pattern to SOM. This similarity may be related to SOM influencing N retention and supply (Brubaker et al, 1993). Total N content with low variability (S.D.…”

“…1). Based on the six categories of landscape position including upper interfluve, lower interfluve, shoulder, upper linear, lower linear and foot slope used by Brubaker et al (1993Brubaker et al ( , 1994, we divided the hillslope into three positions, upper slope, middle slope and foot slope (Wang et al, 2001a). The upper slope position, relative to upper interfluve and lower interfluve, is the uppermost portion of the hillslope.…”

Understanding of the characteristics of soil organic matter (SOM) and soil nutrients at the field and catchment scale is important for refining agricultural management practices and for improving sustainable land use. In order to analyze on SOM and nutrient differences among different land use types and their relationships between land use, landscape position and slope aspect, 94 sampling sites including 7 land uses were selected along 6 transects in the Danangou catchment with an area of 3.5 km 2 on the Loess Plateau of China. Significant differences in SOM, total N (TN), available N (AN) and available P (AP) among these land uses were found. Higher values in SOM, TN and AN were measured in soils from woodland and grassland, but lower values in the soils from fallow land and cropland. Compare SOM and TN with cropland, intercropping land had high contents. The adjusted R 2 values of regression models for SOM and nutrients with land use, landscape position and slope aspect ranged from 0.501 (SOM) to 0.134 (AP). A comparison between average predicted and measured values for SOM and each soil nutrient revealed that the predicted values in TP and AN for each land use, in SOM and TN except for fallow land and in AP except for intercropping land, shrub land and woodland, fell with in a 95% confidence interval about the measured values. The simplified predicted models of soil nutrients combined with the key value of SOM for soil quality can serve to improve agricultural practices and to provide useful information on sustainable land use. Improvement in SOM and nutrients would be expected from more C inputs including manure and crop residues and alternative cultivation practices such as developing intercropping system, building terrace for soil and water conservation, return the cropland with SOM content less than a key value of 0.44% to the grassland and woodland on the hilly areas similar to the Loess Plateau of China. the same time, it is recommended that nitrogen fertilization addition could be decreased in the foot slope and increased on the upper slope.

“…Among the leaf litter fall, 82Á9 per cent of this was hard decomposed needle leaf of slash pine and the decomposition of such litter could produce a great deal of organic acid (Yuan et al, 2003). Brubaker et al (1993) reported that soil organic matter could influence nutrient retention and supply. The similar trend between soil carbon and total nitrogen content may be the result of this.…”

How different reforestation approaches affect red soil properties in southern China

et al. 2005

Significant differences were found in soil physicochemical and biological effects between various forest restoration approaches of a hilly red-soil region, southern China. Soil quality was the highest in natural secondary forest (0Á95), while in sites revegetated with tea-oil camellia (Camellia oleifera), Chinese fir (Cunninghamia lanceolata) and slash pine (Pinus elliottii) and control sites, integrated soil quality indices were 0Á68, 0Á55, 0Á36 and 0Á04 respectively. The lower soil quality of plantations and controls resulted from increased disruption of soil physical structure, lower quality litter fall, lower litter fall production, reduction in microbial biomass, decline of microbial function and loss of soil nutrients due to periodically artificial tending and accelerated soil erosion. Improvement in soil physicochemical properties and enhanced soil microbial function at a natural secondary forest site demonstrated the inherent restoration of these soils. Hence, natural restoration, as well as reducing human disturbance, is a better approach to improving soil properties than returning farmland to planted woodlands.

“…Vários autores correlacionaram o rendimento de culturas e algumas das variáveis físicas e/ou químicas do solo (MILLER et al, 1988e FIORIN et al, 1997 (BRUBAKER et al, 1993;TIMLIN et al, 1998). Pouca ou nenhuma importância é dada para a variabilidade da ação antrópica junto ao rendimento das culturas quando a agricultura de precisão é a área de interesse.…”
