Evaluation of corn production parameters and their spatial relatioship with chemical attributes of the soil. Author(s): MARTINS, A. L. da S.; MOURA, E. G. de; CAMACHO-TAMAYO, J. H. The characterization of the soil spatial variability allows a better understanding of the relationships between the soil attributes and the environment. The objective of the study was to evaluate the... ... Repository: BDPA Publication year: 2011
Site selection for underground dams using spatial multi-criteria evaluation in the semi-arid region of the state of Alagoas, Brazil. Author(s): WEBBER, D. C.; MARQUES, F. A.; OLIVEIRA NETO, M. B. de; BARROS, A. H. C.; SILVA, M. S. L. da A spatial multi-criteria evaluation is proposed to identify suitable locations for underground dams (UD) in the semi-arid state of Alagoas, Brazil. This is a strategic program, which involves a nation... ... Repository: BDPA Publication year: 2019

Influence of spatial arrangements on silvicultural characteristics of three Eucalyptus clones at integrated crop-livestock-forest system. Author(s): FERREIRA, A. D.; SERRA, A. P.; LAURA, V. A.; ORTIZ, A. C. B.; ARAUJO, A. R. de; PEDRINHO, D. R.; CARVALHO, A. M. de This research evaluated the influence of different spatial arrangements on the growth of three Eucalyptus clones as well as the characteristics that influence the quality of the timber. The experiment... ... Repository: BDPA Publication year: 2016
Geostatistical analysis of crop yield maps in a long term no tillage system. Author(s): GUEDES FILHO, O.; VIEIRA, S. R.; CHIBA, M. K.; GREGO, C. R. It is known, for a long time, that crop yields are not uniform at the field. In some places, it is possible to distinguish sites with both low and high yields even within the same area. This work aime... ... Repository: BDPA Publication year: 2010
Spatial analysis of soil physical attributes from a degraded area under different types of management. Author(s): CARVALHO, J. C. B. de; ESPINDOLA, C. R.; ALVES, M. C.; GREGO, C. R.; VIEIRA, S. R. The objective of this work was to analyze the spatial variability of soil aggregates, porosity and density under five different land-uses and management conditions (degraded substrate - SD; degraded s... ...
