O estudo da quantidade e da atividade da biomassa microbiana pode fornecer subs\uffc3\uffaddios importantes para o planejamento do uso correto da terra, considerando a natureza din\uffc3\uffa2mica dos microrganismos do solo. Este trabalho objetivou verificar altera\uffc3\uffa7\uffc3\uffb5es em atributos biol\uffc3\uffb3gicos indicadores da qualidade do solo na ado\uffc3\uffa7\uffc3\uffa3o de sistemas de manejo em \uffc3\uffa1reas originalmente sob cerrado nativo, e selecionar os atributos com melhor desempenho em indicar tais altera\uffc3\uffa7\uffc3\uffb5es. Amostras de solo foram coletadas em tr\uffc3\uffaas profundidades (0-10, 10-20 e 20-40 cm) em Latossolo Vermelho distr\uffc3\uffb3fico t\uffc3\uffadpico textura argilosa no munic\uffc3\uffadpio de Morrinhos (GO). Foram selecionadas cinco propriedades agr\uffc3\uffadcolas, baseadas na sua representatividade para a regi\uffc3\uffa3o com rela\uffc3\uffa7\uffc3\uffa3o ao hist\uffc3\uffb3rico de uso e \uffc3\uffa0s caracter\uffc3\uffadsticas dos sistemas de manejo adotados. Estes consistiram de: cerrado nativo, pastagem, plantio direto, plantio direto com hist\uffc3\uffb3rico de gradagem superficial, plantio convencional de longa dura\uffc3\uffa7\uffc3\uffa3o e plantio convencional recente ap\uffc3\uffb3s pastagem. O cerrado nativo foi tomado como refer\uffc3\uffaancia, uma vez que todos os sistemas foram instalados em \uffc3\uffa1rea originalmente de cerrado. Foram avaliados: carbono da biomassa microbiana (Cmic), respira\uffc3\uffa7\uffc3\uffa3o basal, quociente metab\uffc3\uffb3lico (qCO2) e rela\uffc3\uffa7\uffc3\uffa3o Cmic/CO. Em adi\uffc3\uffa7\uffc3\uffa3o, foram avaliados o carbono org\uffc3\uffa2nico total (CO) e alguns atributos de fertilidade do solo. A ado\uffc3\uffa7\uffc3\uffa3o dos sistemas agr\uffc3\uffadcolas e da pastagem reduziu os teores de Cmic na camada superficial, em rela\uffc3\uffa7\uffc3\uffa3o ao cerrado nativo. Excetuando o s\uffc3\uffadtio sob cerrado, o maior valor de Cmic foi observado na pastagem e o menor no plantio convencional de longa dura\uffc3\uffa7\uffc3\uffa3o. N\uffc3\uffa3o foram observadas diferen\uffc3\uffa7as significativas entre os sistemas de manejo para respira\uffc3\uffa7\uffc3\uffa3o basal e qCO2. O Cmic indicou altera\uffc3\uffa7\uffc3\uffb5es significativas na instala\uffc3\uffa7\uffc3\uffa3o de sistemas de manejo em rela\uffc3\uffa7\uffc3\uffa3o ao cerrado nativo e, embora tenha apontado diferen\uffc3\uffa7as apenas entre dois dos cinco sistemas cultivados, foi indicativo de maior equil\uffc3\uffadbrio da microbiota do solo no cerrado.

Both kinds of soil mechanical impedances often coexist in maize fields, but the combined effects on root growth have seldom been studied. Soil physical properties and maize root abundance were determined in three different soils of the Rolling Pampa of Argentina, in conventionally-tilled (CT) and zero-tilled (ZT) fields cultivated with maize. In the soil with a light Bt horizon (loamy Typic Argiudoll, Chivilcoy site), induced plough pans were detected in CT plots at a depth of 0-0.12 m through significant increases in bulk density (1.15 to 1.27 Mg m-3) and cone (tip angle of 60 \uffc2\uffba) penetrometer resistance (7.18 to 9.37 MPa in summer from ZT to CT, respectively). This caused a reduction in maize root abundance of 40-80 % in CT compared to ZT plots below the induced pans. Two of the studied soils had hard-structured Bt horizons (clay pans), but in only one of them (silty clay loam Abruptic Argiudoll, Villa L\uffc3\uffada site) the expected penetrometer resistance increases (up to 9 MPa) were observed with depth. In the other clay pan soil (silty clay loam Vertic Argiudoll, P\uffc3\uffa9rez Mill\uffc3\uffa1n site), penetrometer resistance did not increase with depth but reached 14.5 MPa at 0.075 and 0.2 m depth in CT and ZT plots, respectively. However, maize root abundance was stratified in the first 0.2 m at the Villa L\uffc3\uffada and P\uffc3\uffa9rez Mill\uffc3\uffa1n sites. There, the hard Bt horizons did not represent an absolute but a relative mechanical impedance to maize roots, by the observed root clumping through desiccation cracks.

The experiment was carried out in a clayey Latossolo Vermelho eutr\uffc3\uffb3fico (Rhodic Eutrudox) in Palotina, PR, Brazil. Increasing doses of pig slurry (0, 30, 60 and 120 m\uffc2\uffb3 ha-1 per year) were applied in both tillage systems, with three replicates. Half of the pig slurry was applied before summer soil preparation, and the other half before the winter crop season. The areas were cultivated with soybean (Glycine max L.) and maize (Zea mays L.) in the summers of 1998 and 1999, respectively, and with wheat (Triticum sativum Lam.) in the winters of both years. Soil samples were collected at 0-5, 5-10, and 10-20 cm depths. Under both CT and NT systems, pig slurry application increased C and N mineralization. However, increasing pig slurry additions decreased the C to N mineralization ratio. Under the NT system, C and N mineralization was greater than in CT system.

This study evaluated the effect of tillage systems (no-tillage - NT and conventional tillage - CT) on soil C and nutrient stocks in an Oxisol from an Amazonian cerrado following land use change. The study also identified relationships between these stocks and other soil attributes. Carbon, P, K, Ca and Mg stocks, adjusted to the equivalent soil mass in the cerrado (CE), were higher under NT. After adoption of all but one of the NT treatments, C stocks were higher than they were in the other areas we considered. Correlations between C and nutrient stocks showed positive correlations with Ca and Mg under NT due to continuous liming, higher crop residue inputs and lack of soil disturbance, associated with positive correlations with cation exchange capacity (CEC), base saturation and pH. The positive correlation (r = 0.91, p < 0.05) between C stocks and CEC in the CE indicates the important contribution of soil organic matter (SOM) to CEC in tropical soils, although the exchange sites are - under natural conditions - mainly occupied by H and Al. Phosphorus and K stocks showed positive correlations (0.81 and 0.82, respectively) with C stocks in the CE, indicating the direct relationship of P and K with SOM in natural ecosystems. The high spatial variability of P and K fertilizer application may be obscuring these soil nutrient stocks. In this study, the main source of P and K was fertilizer rather than SOM.
