“…Pearson's linear correlation results evidenced the positive influence of the increase in M.O. in the physical properties of the soil RP and DP, besides positively influencing the pH of the soil, which would culminate in greater availability of nutrients, since the average pH obtained in the present study was in the range between 4.0 and 4.2 in CaCl 2 , and according to Silva et al (2016), from the nutritional point of view, the adequate range is between 5.6 and 6.2 in CaCl 2 , culminating in greater availability of nutrients for the eucalyptus crop.…”

Eucalyptus cultivation has expanded considerably in Brazil, especially in regions where soils have low fertility, as in the Brazilian Cerrado (Brazilian Savannah). In order to achieve high yield, it is necessary to know the appropriate time and place to perform the soil management, and to assist in this decision-making process, mathematical and computational models has been used and are a promising alternative. The objective of this study was to model the influence of plant and soil physical-chemical attributes on Eucalyptus camaldulensis cultivation in an Oxisol (Latossolo Vermelho distrófico), with clayey texture with the purpose of demonstrating specific management areas closely associated with eucalyptus development. An experimental grid of approximately 2 hectares (ha) containing 40 sampling points were installed and later soil and plant attributes were collected for the determination of physical and chemical attributes in the 0-0.20 m and 0.20-0.40 m layers in Selvíria, MS, Brazil. The results were analyzed using classical and geostatistical statistics. The spatial dependence varied according to the physical attribute evaluated and the depth of sampling. In addition to the vertical variability, there was also horizontal variability between depths, since for the same attribute the range was different between the sampled layers.

“…Além disso, alguns autores citam que a serapilheira do pinus se caracteriza pelo baixo teor de nutrientes e lenta decomposição, em função da alta relação C/N e compostos fenólicos e ligninas encontrados nas acículas, o que reduz o desenvolvimento de microrganismos, diminuindo assim a incorporação de C no solo (CARVALHO et al, 2008;SARTOR et al, 2009;ALMEIDA et al, 2012). Já outros estudos destacam a produção de serapilheira pelo pinus e sua importância sobre a ciclagem de nutrientes no solo (VIERA;SCHUMACHER, 2010;PIOVESAN et al, 2012), o que pode contribuir para a melhoria das condições químicas do solo (SILVA et al, 2016).…”

Os plantios de espécies florestais exóticas vêm aumentando em áreas cobertas por vegetação nativa na região nordeste do Rio Grande do Sul, o que pode alterar as dinâmicas dos nutrientes no solo. Dessa maneira, o objetivo deste estudo foi avaliar os efeitos da mudança de uso da terra sobre pH e teores de carbono orgânico total (COT), Al3+, Ca2+, Mg2+ e K+ em Cambissolo Húmico, em plantios realizados em área de campo nativo. As áreas analisadas foram pinus plantado em 1963 (P) e eucalipto em 1991 (E), comparativamente a áreas adjacentes remanescentes: de campo nativo em regeneração natural a partir de 1990 (RN), mata nativa (MN) e campo nativo (CN). As amostras de solo foram coletadas nas profundidades de 0-5, 5-10 e 10-20 cm, em oito pontos para cada área avaliada, com cálculo de médias e intervalos de confiança (95%). Em geral, CN e MN apresentaram os maiores valores de COT. O plantio “P” apresentou em relação ao CN menores teores de COT, Ca e K na camada 0-10 cm, enquanto o plantio “E” apresentou menores teores de COT em relação ao CN, indicando efeitos negativos da floresta plantada em relação à vegetação natural campestre quanto à ciclagem de carbono e nutrientes. A área RN apresentou valores desses atributos similares aos do CN e MN. Avaliações em longo prazo são importantes para verificar influências do cultivo florestal sobre atributos do solo e identificar a sustentabilidade das formas de uso do solo.

“…Another problem that we acknowledge is the use of exotic species in Cerrado restoration, which has been misleadingly related to low availability of native seedlings (Da Silva et al 2016).…”

Ecological knowled ge plays a signifi cant role in ensuring effi cient ecological restoration. We conducted a systematic review to assess if suffi cient ecological knowledge has been accumulated to aid restoration practices for the Cerrado, a Brazilian biome dominated by savanna ecosystems and threatened by anthropogenic disturbances.Most Cerrado restoration studies were performed by few research groups and focused primarily on two vegetation types: cerrado sensu stricto (typical savanna) and riparian forest. We also found that defi ning reference ecosystems and selecting plant species for restoration programs is neglected, mostly disregarding their original occurrence and proportion of plant growth forms. Furthermore, studies lacked standardized and systematic evaluation of restoration outcomes. Hence, we argue that current ecological knowledge is insuffi cient to guarantee the success of large-scale ecological restoration of the Cerrado. We strengthen the need to explicitly defi ne the reference ecosystem for each Cerrado ecosystem and use its structure and composition as guidance for ecological restoration research, which should be based on a scientifi c approach. We encourage investigations into ecological dynamics and natural regeneration of the different vegetation types of the Cerrado and highlight the importance of integrating such knowledge with environmental laws, societal engagement and cost-effective techniques to advance Cerrado ecological restoration.
