DOI: 10.1016/j.chemgeo.2019.04.023
Abstract: Abstract Storms are responsible for up to ~50% of total annual rainfall on tropical islands and result in rapid increases in discharge from rivers. Storm events are, however, notoriously under-sampled and their effects on weathering… read more here.

DOI: 10.1016/j.envpol.2020.116009
Abstract: Biochar has been proven as a soil amendment to improve soil environment. However, mechanistic understanding of biochar on soil physical properties and microbial community remains unclear. In this study, a wood biochar (WB), was incorporated… read more here.

DOI: 10.1016/j.foreco.2019.117522
Abstract: Abstract Although disturbances associated with selective logging can cause pronounced changes in soil characteristics and nutrient stocks, such information is very limited for highly weathered soils in Africa. We assessed the effects of reduced impact… read more here.

DOI: 10.1016/j.gca.2016.12.032
Abstract: In order to assess the effects of critical zone processes on Mg concentrations and isotopic signatures of tropical streams, we studied a well constrained, highly weathered andesitic volcaniclastic catchment in the Luquillo Critical Zone Observatory,… read more here.

DOI: 10.1016/j.geoderma.2020.114681
Abstract: Abstract Dust deposition is an important source of phosphorus (P) to many ecosystems. However, there is little evidence of dust-derived P-containing minerals in soils. Here we studied P forms along a well-described climatic gradient on… read more here.

Solid Phase Speciation and Solubility of Vanadium in Highly Weathered Soils.
Sign Up to like & getrecommendations! Published in 2017 at "Environmental science & technology"
DOI: 10.1021/acs.est.7b01005
Abstract: Vanadium (V) is increasingly recognized both as a medical trace element with essential biological functions and as a potentially toxic environmental pollutant, yet the current knowledge on V speciation in soils is limited. Here, we… read more here.

Biochars Improve Nutrient Phyto-Availability of Hawai’i’s Highly Weathered Soils
Sign Up to like & getrecommendations! Published in 2018 at "Agronomy"
DOI: 10.3390/agronomy8100203
Abstract: Highly weathered soils in Hawai’i are low in fertility, negatively affecting plant growth. The potential of biochar for improving soil nutrient availability to crops is promising, and prompts this study. Two biochars at 2% (w/w)… read more here.
