“…For the Vertisols, cultivation led to phosphorous pattern as 1.2 times higher and 2.3 times lower than the adjacent soil under grassland and forest, respectively. These results are in line with other authors (Bowman et al 1990; Hajabbasi 1997;Liu et al 2002). Significant increase of P content (P B 0.05) in the forestland (Table 5) may be associated with relative high SOC and low erosion in the land use type.…”

“…For example, the data found by Du Toil et al (1994) in South Africa indicated that 5-90 years land use for cultivation resulted in a loss of 10-73 % of C and N concentration compared to the native grassland. In USA, when a grassland soil was converted into cultivated land for 60 years, it was highlighted by Bowman et al (1990) that total organic C, N, and P had decreased by 55-63 %. Zhao et al (2005) mentioned that total N and total P concentrations had declined 60-70 % and 67-68 % in the 0-20 cm plough layer, respectively, as result of cultivation of grassland.…”

Monitoring general variability of soil attributes is a fundamental requirement from the point of view of understanding and predicting how ecosystems yield. In order to monitor impact of different land use types on the combination of morphological, clay mineralogical and physicochemical characterizes, 42 soil samples (0-30 cm) were described and analyzed. Soil samples belonging to Cambisols and Vertisols reference soil groups collected from three neighboring land use types included cropland (under long-term continuous cultivation), grassland, and forestland. The soils were characterized by high pH (mean of 7.1-7.5) and calcium carbonate equivalent (CCE) (mean of 35-97 g kg -1 ) in the three land use types. The weakening in soil structure, hardening of consistency, and lighting of soil color occurred for the cropland under comparable condition with grassland and forest. Changes in land use types produced a remarkable change in the XRD patterns of clay minerals containing illite and smectite due the dynamic and removal of potassium. Continuous cultivation resulted in an increase in sand content up to 35 % while silt and clay content decreased up to 22 and 18 %, respectively, as compared to the adjoining grassland and forest mainly as a result of the difference of dynamic alterational and erosional process in the different land use. Long-term cultivation caused a negative and degradative aspects on soil heath as is manifested by the increasing in soil pH (a rise of 0.3-0.46 unit), electrical conductivity (EC) (a rise of 1.78-5.5 times), sodium absorption ration (SAR) (a rise of 10-51 %), exchangeable sodium percentage (ESP) (a rise of 3-46 %), and the decrease in soil organic C (a drop of 12-41 %), along with soil fertility attributes. Overall, the general distribution of soil organic C, total N, available P and K, cation exchange capacity (CEC), and exchangeable cations (Ca, Mg, and K) followed the order: forestland [ grassland [ cropland. The general distribution of EC, SAR, ESP, and exchangeable Na, however, followed the order: cropland [ grassland [ forestland. Soil quality index (SQI), calculated based on some physicochemical properties, specified that cultivation led to a negative effect in SQI for both Cambisols (a drop of 10-17 %) and Vertisols (a drop of 17 %) as compared to those of under grassland and forestland.

“…Results showed that soil quality improved with time due to accumulation of TOC, TN, TP, and improvement of soil texture. Similar results were reported in terrestrial ecosystems (Browman et al, 1990;Peng, 1995;Kosmas et al, 2000;Comin et al, 2001;Singh et al, 2001;Lee et al, 2002;Bruland & Richardson, 2004, 2005. Soil pH in riparian areas ranged from 4.90 to 5.28 in the 0-20 cm layer and 5.68 to 5.92 in the 20-40 cm layer in Fig.…”

Riparian wetlands are important components of the lake ecosystem, and they play essential roles in maintaining system health. Remediation of degraded lakeshore wetlands is an essential component of lake restoration. A study was conducted to investigate the restoration of lakeshore wetlands, which were converted to rice fields and then abandoned for 2, 5, 10 and 15 years, near Lake Taihu. Soil samples (0-20 cm and 20-40 cm) were taken and plant species were investigated. The carbon content in the soil had increased significantly, rising from 0.71% to 1.85% between 2 and 15 years. Organic matter accumulation improved soil texture, and water stable aggregate content (>0.25 mm) and soil porosity increased. Total nitrogen in the soil increased from 0.06% to 0.13%, and total Kjeldahl nitrogen increased from 124.4 mg kg -1 to 351.5 mg kg -1 . Total phosphorus in the soil increased from 0.045% to 0.071%, and the Olsen-P value increased from 5.13 mg kg -1 to 16.0 mg kg -1 . Results showed that phosphorous did not increase as much as nitrogen. In the vegetation restoration process, plant species composition moved towards a natural wetland community, and spatial heterogeneity and landscape diversity increased. The richness of plant biodiversity increased rapidly in the first 2 years, then more slowly in later restoration stages. The wetlands recovery process may be complicated by interactions of biota and soil and hydrological conditions.

“…Por essa razão, alguns estudos têm avaliado, adicionalmente à matéria orgânica total, atributos como biomassa microbiana (Powlson et al, 1987;Vargas, 1997) e matéria orgânica leve (Powlson et al, 1987;Jansen et al, 1992), os quais são mais sensíveis, permitindo uma avaliação antecipada da qualidade dos sistemas de manejo de solo adotados. Bowman et al (1990) encontraram reduções de 55 a 63% no conteúdo de carbono orgânico total do solo (0-15 cm) em sessenta anos de cultivo. Na fração leve da matéria orgânica, a redução foi de 67 a 72%, ocorrendo 87% deste declínio nos primeiros três anos.…”

RESUMOA matéria orgânica é um dos atributos de solo mais sensível às transformações desencadeadas pelos sistemas de manejo. Neste estudo, foram avaliados os conteúdos de C e N na matéria orgânica total e na sua fração grosseira, bem como as características químicas de um Cambissolo Húmico submetido ao preparo convencional, preparo reduzido e plantio direto, durante nove anos, no município de Lages, SC. O plantio direto e o preparo reduzido promoveram incrementos de 8,5 e 6,3 t ha -1 de C e 808 e 593 kg ha -1 de N na camada de 0-20 cm do solo, respectivamente, em relação ao preparo convencional. Os incrementos relativos do conteúdo de C e N na matéria orgânica total foram de 12 e 17%, respectivamente, no preparo reduzido, e de 17 e 24%, respectivamente, no plantio direto. A fração grosseira da matéria orgânica (> 53 µ µ µ µ µm) foi mais sensível ao sistema de preparo de solo do que a matéria orgânica total. Na fração grosseira, os incrementos de C e N foram de 85 e 45%, respectivamente, no preparo reduzido, e de 275 e 230%, respectivamente, no plantio direto, demonstrando ser um atributo adequado para avaliar o efeito de sistemas de manejo a curto prazo. A CTC efetiva do solo foi relacionada com o pH e com os teores de carbono (CTC efetiva = -13,53 + 3,58 pH + 3,51% C, R 2 = 0,76), demonstrando ser a matéria orgânica um contribuinte importante para a CTC desse solo. No plantio direto, ocorreu pequena estratificação de Ca e grande estratificação de P e K em profundidade, em comparação ao preparo reduzido e convencional. O pH e o Al não foram afetados pelos sistemas de preparo de solo. Não foi observada limitação química ao desenvolvimento vegetal e à produção das culturas nos três preparos de solo.
