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
Legacy data: exploratory analysis to digital soil class mapping. Author(s): CARVALHO JUNIOR, W. de; BHERING, S. B.; PEREIRA, N. R.; CHAGAS, C. da S.; LOPES, C. H. L. The use of legacy data improve the value of these data and promote the input of new data on the database. Also, reduces the primary data collection and analytical procedures. In MS State, the legacy d... ... Repository: BDPA Publication year: 2022
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
