- ÍtemAnálisis del Diseño de Experimentos de los Macroelementos del suelo de 15 fincas en el municipio de Abrego, Norte de Santander.(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Leal Lozada, Luisa Fernanda; Santana Alfonso., Adrian AlbertoThe objective of this article is to validate the hypothesis that there are significant differences between the first and the last model demonstrated and between those of polycultures for the results of soil analyzes of 7 essential elements in the soil: Nitrogen, Phosphorus, Potassium, Sulfur, Calcium, Magnesium and Boron. The methodology applied was a Completely Randomized Block Design with a type of analysis of ANOVA model III, that is, mixed considering that the factor is the two demonstrated and the blocks are the different polyculture models, the results obtained show that only nitrogen and potassium showed differences, the first between those demonstrated and the second between the models, it is concluded that these results may be due to external factors such as the use of products with a large amount of content of certain elements, a possible failure in the sampling, due to the presence of microorganisms in the soil and the short time between those examined.
