Classification to Coefficient of Variation in Physical and Chemical Attributes of Oranges

Brazilian Journal of Experimental Design, Data Analysis and Inferential Statistics, 2022
Abstract: A of the ways to evaluate data homogeneity in experiments is through the coefficient of variation (CV), however, in orange fruit evaluations, gaps are noted about the ranges that the variables must present due to their fluctuations as a function of factors genetic, climatic and agricultural.

MINING RESIDUE IN THE COMMERCIAL LIMESTONE BLENDING AND THE CHEMICAL ATTRIBUTES OF A LATOSOL

REVISTA ENGENHARIA NA AGRICULTURA - REVENG, 2020
The limestone mining activity causes environmental impacts due to the generation of waste. However, the reuse of these residues has been investigated with the objective of improving soil fertility and acidity correction. The objective of this work was to evaluate the potential for using mining residues in the commercial limestone blending and in the ...

Chemical, physical, and biological attributes of the soil in integrated systems

Brazilian Journal of Science, 2023
Integrated systems are conservationist and sustainable systems with great prominence on the national scene for reducing financial and productive risk in the agricultural sector and reducing environmental damage. One of the successes of these systems is to see the cultivation environment in an integrated way, knowing each of its components; soil, plant,
