Soil Taxonomy

There are approximately 700 soil series in the Philippines.
The most detailed category in Soil Taxonomy is the Series.
The purpose of Soil Taxonomy is to provide a standardized system for classifying soils based on their properties and characteristics.
The presence or absence of diagnostic horizons determines the Suborder in Soil Taxonomy.
The Lipa Series represents a specific soil series in Soil Taxonomy.
The Natric horizon contains high levels of sodium ions.
The Family category in Soil Taxonomy is determined by factors such as the texture, mineralogy, and temperature regime of the soil.
The Oxic horizon is characterized by high levels of iron oxides and quartz.
The characteristic that determines the Great Groups in Soil Taxonomy is the presence or absence of certain diagnostic horizons.
The purpose of establishing groups or classes for practical purposes in Soil Taxonomy is to help manage and utilize soil resources effectively.
