Determination of the Soil Quality Index by Principal Component Analysis in Cocoa Agroforestry System in the Orinoco Region, Colombia

Sergio David Parra-González & Jeisson Rodriguez-Valenzuela · Journal of Agriculture and Ecology Research International · 2017

Soil quality index can be determined by assessing the physical, chemical and biological properties of the soil. When large datasets are used, redundant information is obtained very often. Therefore, principal component analysis (PCA) is a multivariate method that allows the reduc...

Assessing Functions of Pedotransference to Determine Microporosity for a Soil (Typic Hapludox) under Two Conditions of Use in the Orinoco Region Colombia

Edwin Esteban Reyes Alvarez, Sergio David Parra-González & Jeisson Rodriguez-Valenzuela · Journal of Agriculture and Ecology Research International · 2019

Microporosity is a property that influences not only on fluid dynamics but also on the flow of chemical substances and plant growth. Likewise, it is known that microporosity is difficult to be determined due to the broad variety of methods that implies using of equipment and asse...
