Título:  Influence of limestone and gypsum application on chemical attributes of dystrophic yellow latosol soil and corn yield in Eastern Amazon.

Conteúdo:  The objectiveof this study was to evaluate changes in the chemical attributes of the soil caused by the use of limestone associated or not to with gypsum in no-tillage system. The experiment was conducted on a dystrophic Yellow Latosol in Pará state,Brazil. The experimental design was in randomized blocks in split plots with three replications. The treatments consisted of five doses of limestone (0, 1, 2, 3 and 4 t ha-1), with and without gypsum (0, 0.5 and 1 t ha-1). Soil samples were collected at depths of 0-20 and 20-40 cm. There was a significant effect on the analyzed variables at both depths. The doses of 3.64 and 2.19 t ha-1of limestone associated with 0.5 t ha-1of gypsum, were responsible for the largest increase in soil calcium content in the 0-20 and 20-40 cm layers, respectively. The highest increase in Ca + Mg content was found at 3.63 t ha-1limestone combined with 0.5 t ha-1gypsum. It was observed that 3.13 t ha-1of limestone combined with 0.5 t of gypsum increased soil CEC. The 2.89 t ha-1dose of limestone combined with 0.5 t of gypsum contributed to the increase in base saturation (V%). The use of limestone and gypsum promotes soil chemical conditions, as reflected by increased corn yield when compared with control (no treatment) plots.

Título:  Artificial neural networks applied in forest biometrics and modeling: state of the art (January/2007 to July/2018).
Ano de publicação:  2019
Fonte/Imprenta:  Cerne, v. 25 n. 2, p. 140-155, Apr./June 2019.

Conteúdo:  Artificial Intelligence has been an important support tool in different spheres of activity, enabling knowledge aggregation, process optimization and the application of methodologies capable of solving complex real problems. Despite focusing on a wide range of successful metrics, the Artificial Neural Network (ANN) approach, a technique similar to the central nervous system, has gained notoriety and relevance with regard to the classification of standards, intrinsic parameter estimates, remote sense, data mining and other possibilities. This article aims to conduct a systematic review, involving some bibliometric aspects, to detect the application of ANNs in the field of Forest Engineering, particularly in the prognosis of the essential parameters for forest inventory, analyzing the construction of the scopes, implementation of networks (type ? classification), the software used and complementary techniques. Of the 1,140 articles collected from three research databases (Science Direct, Scopus and Web of Science), 43 articles underwent these analyses. The results show that the number of works within this scope has increased continuously, with 32% of the analyzed articles predicting the final total marketable volume, 78% making use of Multilayer Perceptron Networks (MLP, Multilayer Perceptron) and 63% from Brazilian researchers.
