The purpose of this study was to evaluate the observed climatic data of the last 14 years of monthly rainfall and temperatures in Lavras, MG region, comparing with those of the historical series of 1961-1990 period. The ...

The evaluation of the spatial dependence requires the use Geoestatistic Analisys. The culture of the beans was used to evaluate the spatial variability of the production, being able this being correlated with other ...

The objective of the present work was to evaluate the spatial variability of the soil texture, field capacity (θcc), permanent wilting point (θpwp) and available water of the soil for plants (AW) using classical ...

This work had as objective to investigate the development of the foliar area of the irrigated sesame (Sesamum indicum L.) in its initial growth until the 70 days after the sowing with the application of four sources of ...

The aim of this research work was to evaluated the soil water and its influence on bean crop production associated to no-tillage and tillage systems, submitted to sprinkle irrigation system. A trase model TDR humidity ...

The objective of this work was to determine the variability in the time and in the space of the evapotranspiration of reference (ET0) for the state of Minas Gerais during the year. The values of ET0 were dear for the ...

The spatial variability of saturated hydraulic conductivity (Ko) was measured on field for non tillage and conventional tillage systems. The measurements had been carried out by means of a constant charge permeameter, ...

The heterogeneity of agro-climatic, social and economic situation in the Brazilian semi-arid land requires some local adaptations of water resources uses and conservation technologies. For this reason, there are many ...

Currently the fractals geometry have been used as an alternative tool for elaboration of mathematics models in the estimate of the water retention curve in the soil. Utilizing the fractal geometry concepts, BROOKS e ...

The objective of the work was to evaluate some models to predict soil solution electrical conductivity (CEw) as a function of soil water content ( ) and bulk electric conductivity (CEa) data obtained under field conditions ...
