“…It is often impossible to fully rehabilitate an ecosystem after a first attempt; the impacting agents are mitigated initially by being covered with soil (Rovedder & Eltz, 2008). Revegetation improves water retention and infiltration, increases the organic matter content, and fosters biological activity (Klamt & Schneider, 1995).…”

Rehabilitation with forage grasses of an area degraded by urban solid waste deposits

et al. 2012

-Dry matter yield and chemical composition of forage grasses harvested from an area degraded by urban solid waste deposits were evaluated. A split-plot scheme in a randomized block design with four replicates was used, with five grasses in the plots and three harvests in the subplots. The mineral content and extraction and heavy metal concentration were evaluated in the second cut, using a randomized block design with five grasses and four replicates. The grasses were Brachiaria decumbens cv. Basilisk, Brachiaria ruziziensis, Brachiaria brizantha cv. Marandu and cv. Xaraés, and Panicum maximum cv. Tanzânia, cut at 42 days of regrowth. The dry matter yield per cut reached 1,480 kg ha -1 ; the minimum crude protein content was 9.5% and the average neutral detergent fiber content was 62.3%. The dry matter yield of grasses was satisfactory, and may be an alternative for rehabilitating areas degraded by solid waste deposits. The concentration of heavy metals in the plants was below toxicity levels; the chemical composition was appropriate, except for phosphorus. The rehabilitated areas may therefore be used for grazing.

“…In the western region of Rio Grande do Sul state, there are sandstone cores that developed due to the composition of the rocky base, the relief and water regime of the site, and worsened by anthropic activities. It is common to observe the formation of mixed prairie vegetation under the sands, which is constantly degraded by the action of water and wind erosion (SUERTEGARAY, 1995;ROVEDDER & ELTZ, 2008).…”

“…Considering that soil is a slowly renewable natural resource, emergency techniques to contain wind erosion and stabilize soil surface are carried out in these regions. The use of fast-growing tree species for instance, makes it possible to start the process of recovery of these degraded areas, rebalancing nutrient cycling and incorporating organic matter into the soil (ROVEDDER et. al, 2008).…”

Young stands on sandy soils with low natural fertility are more dependent on chemical fertilization. The litterfall becomes the most important route for biogeochemical cycling in an ecosystem. Therefore, the aim of the study was to quantify the annual litterfall, evaluate the seasonality of deposition and verify the litterfall response under different amounts of fertilizers in a young eucalyptus stand implanted in soil degraded by arenization in southern Brazil. Litterfall was evaluated using litter traps with an area of 0.5 m². Fortnightly, over a year, collections and quantification of dry mass were performed. Each of the 5 fertilizer treatments received increasing amounts of nutrients. The litterfall had seasonal pattern, with larger quantities for the spring season, with statistical difference at a level of 5% probability of error from other seasons evaluated, marked by the increase in temperatures. The amount of litterfall, in descending order, followed the amount of nutrients applied in the treatments: T5 > T3 > T4 > T2 > T1. The annual litterfall ranged from 518 to 1326 kg ha-1 of the treatment that received natural phosphate (T1) and triple superphosphate (T5), respectively. This variation represents an increase of 156%. The increase in litterfall is associated with the amount of fertilizers.

“…The no-tillage system (NTS) has been presented as the best tillage system due to its management advantages (soil non-tillage), plants coverage (increased yield), resulting in soil protection against external impacts of rain and air, improving soil-water-plant relations (Rovedder & Eltz, 2008;Bertioli Junior et al, 2012;Moreira et al, 2014;Bonini et al, 2016;Torres et al, 2018). Moreira et al (2014) state that NTS translates into specific relations of soil physical properties, such as soil porosity, adapted to the management of this system, showing satisfactory results even with the increase of the soil resistance.…”

“…In the restoration early stages, the priority is the rehabilitation of the ecosystem function and services. This means that it is often impossible to rehabilitate the original structure of an ecosystem in the first moment, when it is urgent the mitigation of impacting agents by immediate ground covering (Rovedder & Eltz, 2008).…”

The objective of this study was to study the physical attributes and the organic matter of a Red-Yellow Oxisol cultivated with Urochloa decumbens pasture in recovery with different introducing ways of Stylosanthes cv. Campo Grande. The experiment was conducted at the Agency for Agribusiness Technology of São Paulo (APTA), in the municipality of Andradina/ SP, between October 2016 and September 2017. The experimental design was the randomized complete block design with four replicates and the treatments were composed of six strategies (partial desiccation, total desiccation, scarification, "rome" harrowing and plowing + harrowing.) in the no-tillage legume in the pasture, in addition to the control. Stability of aggregates, flocculation, soil porosity, organic matter and soil texture were evaluated in three layers: 0-0.10; 0.10-0.20 and 0.20-0.40 m. Soil organic matter content was higher in the topsoil layers (from 15.75 to 17.75 mg dm -3 ) and decreased with depth (from 10.50 to 11.50 mg dm -3 ). The indicated macroporosity was below the value considered ideal for the plants development. Studied treatments did not influence the organic matter content, porosity and soil density. Soil quality was influenced up to 0.20 m with the introduction of stylosanthes, regardless of the adopted management.Recuperação de pastagem utilizando Estilosantes cv. Campo Grande: efeito na qualidade do solo RESUMO: Objetivou-se estudar atributos físicos e a matéria orgânica de um Latossolo Vermelho Amarelo cultivado com pastagem de Urochloa decumbens em recuperação com diferentes formas de introdução de estilosantes cv. Campo Grande. O experimento foi realizado na Agência Paulista de Tecnologia dos Agronegócios (APTA), no município de Andradina/SP, entre outubro de 2016 e setembro de 2017. O delineamento experimental foi em blocos ao acaso, com quatro repetições e os tratamentos foram compostos por seis estratégias (dessecação parcial, dessecação total, escarificação, gradagem rome e aração +gradagem) em plantio direto da leguminosa na pastagem, além da testemunha. Foram avaliados a estabilidade de agregados, floculação, porosidade, matéria orgânica e textura do solo, em três camadas: 0-0,10; 0,10-0,20 e de 0,20-0,40 m. O teor de matéria orgânica no solo foi superior nas camadas superficiais (15,75 a 17,75 mg dm -3 ) e diminuiu em profundidade (10,50 a 11,50 mg dm -3 ). A macroporosidade indicada ficou abaixo do valor considerado ideal para o desenvolvimento das plantas. Os tratamentos estudados não influenciaram o teor de matéria orgânica, a porosidade e densidade do solo. A qualidade do solo foi influenciada até 0,20 m com a introdução do estilosantes, independente do manejo adotado.
