ABSTRACT Considering that nematodes are quite sensitive to anthropic interventions, these organisms can be used as indicators of soil quality (SQ). The objective of this work was to study chemical and physical attributes and soil nematode as an indicator of soil quality in pasture areas with successive application of pig slurry (PS) in the Northwest of the state of Rio Grande do Sul. For this, the different areas were considered: Azevém + Tifton pasture with PS use for 14 years (A14), Azevém + Tifton pasture with use of PS for two years (A2) and native forest (NF), with a chemical and physical attributes nematofauna of the soil, with three replicates per treatment, in a randomized complete block design. The soil chemical attributes were sensitive to changes in pasture areas with successive application of PS, with increase in P content, compared to the NF area and soil OM content in the A14 area similar to that found in the NF area. In relation to the soil physical attributes, density and microporosity increased with the successive application of PS in ryegrass + tifton pasture areas, while macroporosity decreased, compared to NF areas. The nematodes of the Discocriconemella, Paratylenchus, Pratylenchus, Trichodorus, Tylenchus and free-living groups were efficient as indicators of soil quality, since they were able to evidence alterations in soil chemical and physical attributes between the ryegrass + tifton use of PS and in relation to the native forest.

Proper soil management interferes in the result of the installed crop. The knowledge of the positive and/or negative influence on the production systems is essential to improve the physical, chemical and biological quality of the soil and, for that, there are some attributes that act as indicators of soil quality. Practices carried out improperly will result in problems in soil structure, such as compaction, lack of availability of water and air in the soil and for plants, soil loss among others. Some properties as soil porosity, aggregation, compaction, water infiltration are used to measure soil quality. Given this, the use of these attributes as indicators is of utmost importance for excellent productivity, since management practices can directly influence the development of plants.

ABSTRACT This study aimed to determine and spatialize the soil quality index (SQI), in relation to chemical and physical attributes, and evaluate its use in the payment for environmental services in the Sub-Basin of Posses, Extrema-MG, Brazil, which represents the Atlantic Forest Biome. SQI values were influenced by both the replacement of native forests by stands of eucalyptus and by pastures and annual crops, reflecting in the reduction of soil quality in the sampled layer in the evaluated systems. The spatialization of SQI showed values ranging from 0.40 to 0.80, with some specific areas with high values and others with values above 1.00 (native forest). The reforestation with eucalyptus conditioned most of the soils with low chemical and physical deterioration, due to accumulation of litter. The lowest SQI values are associated with pastures. SQI adjusted to the exponential model, which allowed the use of ordinary Kriging. The SQI has a great potential of use in the payment to farmers who provide services of soil and water conservation.

Humping/hollowing and flipping are land development practices widely used on the West Coast to overcome waterlogging constraints to pasture production. However, there is very limited information about how the resulting "new" soils function and how their properties change over time following these extreme modifications. We hypothesised that soil quality will improve in response to organic matter inputs from plants and excreta, which will in turn increase nutrient availability. We tested this hypothesis by quantifying the soil organic matter and nutrient content of soils at different stages of development after modification. We observed improvements in soil quality with increasing time following soil modification under both land development practices. Total soil C and N values were very low following flipping, but over 8 years these values had increased nearly five-fold. Other indicators of organic matter quality such as hot water extractable C (HWC) and anaerobically mineralisable N (AMN) showed similar increases. With large capital applications of superphosphate fertiliser to flipped soils in the first year and regular applications of maintenance fertiliser, Olsen P levels also increased from values

Soil, itself means Soul of Infinite Life. Soil is the naturally occurring unconsolidated or loose covering on the earth’s surface. Physical properties depend upon the amount, size, shape, arrangement, and mineral composition of soil particles. It also depends on the organic matter content and pore spaces. Chemical properties depend on the Inorganic and organic matter present in the soil. Soils are the essential components of the environment and foundation resources for nearly all types of land use, besides being the most important component of sustainable agriculture. Therefore, assessment of soil quality and its direction of change with time is an ideal and primary indicator of sustainable agricultural land management. Soil quality indicators refer to measurable soil attributes that influence the capacity of a soil to function, within the limits imposed by the ecosystem, to preserve biological productivity and environmental quality and promote plant, animal and human health. The present study is to assess these soil attributes such as physical and chemical properties season-wise.
