“…A higher clay content in mounds was also reported by Oliveira et al (2012), but not for the other fractions. Contrary to the findings of these authors, Kaschuk et al (2006) observed no differences between the clay contents in mounds and the surrounding soils.…”

ABSTRACT:Termites have peculiar activities in the soil, inducing significant changes in the soil properties. The objective of this study was to assess physical and chemical properties and soil organic matter to evaluate the effect of termite activity and termite mounds on the soil. Two toposequences were selected and divided in slope thirds (shoulder, backslope, and footslope). In each of these, four termite mounds were selected. Samples were taken from the soils and termite mounds (top, center, and base) along with a variety of termites for identification. Analyses were carried out for physical, soil texture, and chemical properties, as well as for particle size and chemical fractioning of organic matter. The species Cornitermes cumulans was found in all mounds. Soil with termite mound presented higher clay content, acidity, and Al 3+ content. Phosphorus contents differed considerably between mound material and soil. Sum of bases and cation exchange capacity of the soil were higher in mounds, and differed within the mounds, according to the sampling height. Total organic carbon and particulate carbon content were highest at the mound base. A marked disparity was observed between the contents of humic substances in the mounds and surrounding soil, with humin fraction differences in distinct topographic position. The high nutrient contents detected in the termite mounds confirm the importance of termites in concentrating nutrients.

“…In our study, clay and sand seemed to be used almost in the same proportion, whereas silt was used in lower proportion. This is a different pattern than that found by Oliveira et al (2012), who observed higher proportions of sand and silt than that of clay in the mounds. This difference is probably explained by the builder species which determine the material used, however, assertions related to particle size are still scarce.…”

“…K + is easily translocated, and although Mg +2 does not have the same mobility as K + , it showed the same pattern. Our results are similar to those observed by Oliveira et al (2012) and Sarcinelli et al (2009) Mean values (7 replicate) followed by the same letter within columns are not significantly different according to Bonferroni test (P < 0.05).…”

“…Rückamp et al (2010) quantified and systematized phosphorus forms in different sections of termite mounds (exterior wall, internal wall, and center) of different trophic guilds and soils in seven Brazilian ecosystems and concluded that termite activity results in a gross enrichment of phosphorus in labile form in nets, and the composition of P in termite constructions is reflected in their diet. According to Oliveira et al (2012), the higher amount of P in termite mounds than in the adjacent soil is related to the amount of clay used in their construction, which hinders the loss of P available.…”

“…Sarcinelli et al (2009) compared internal sections of epigeal mounds with samples of adjacent areas and assessed their physicochemical properties. Oliveira et al (2012) assessed changes in physicochemical properties of epigeal mounds compared to soil samples of adjacent areas as well. These authors considered a mound subdivided in top, center, and base and compared it to the adjacent soil within a radius of 1.5 m from the base of the epigeal mound.…”

Soil Physical and Chemical Properties in Epigeal Termite Mounds in Pastures

et al. 2018

We characterized soil physical and chemical properties and soil organic matter in epigeal termite mounds in pastures to evaluate the changes promoted by termites in comparison to an adjacent area. We selected seven active epigeal termite mounds in the municipality of Seropédica, state of Rio de Janeiro, Brazil. Soil samples were collected from top, center and base positions of each mound, at 0.50 and 1.50 m distance from the base of the mound. We identified individuals of the genus Embiratermes, Velocitermes, and Orthognathotermes. The humin fraction predominated over the humic and fulvic acid fractions both in mounds and adjacent soil. The amount of organic matter and the mineral fractions (mineral-associated organic carbon -MOC) varied among builder species. The studied chemical attributes point to a higher concentration of nutrients in the mounds than in the adjacent soil.
