On the rejuvenation of tropical Iaterttes by the incorporation of basalt dust
O. D'HOTMAN DE VILLIERS
ABSTRACT:
1. The work of N. Craig and P. Halais of the. Reoherches Station as well as our own research on the soils and climates of the island, having amply shown that our soils of the wet regions are in an extreme state of climatic poor, we have the idea of regenerating them by incorporating powdered basalt.
2. This idea that has worried us for several years and which seems to us to be the logical focus of the genetic study of tropical soils, will bring, we are convinced, a happy revolution in soil science under climates where atmospheric agents are the cause of a deep decomposition by hydrolysis and a rapid exhaustion ...
Further results of studies on the rejuvenation of exhausted soils in humid districts by incorporating basalt dust.
O. D’Hotman de Villiers
ABSTRACT:
Results are republished of the 1938-41 experiments conducted in Mauritius with powdered basalt and heavy NPK fertilizer applications on sugar-cane crops grown in exhausted lateritic soil. With these are compared the results of the 2nd series of experiments (1944-47) on the same plots, in which, after a bare fallow of 23 months, moderate N and minimum P and K applications were combined with 10 metric tons/arpent of powdered basalt. The 1937 basalt dressings had been 10, 30 and 90 metric tons.
Results show a striking residual benefit, especially from the highest basalt application, affecting both cane and sugar ...

The Use of Ground Rocks in Laterite Systems: An improvement to the use of Conventional Soluble Fertilizers?
Othon H. Leonardos, W. Fyfe, B. Kronberg
ABSTRACT:
The geochemistry of lateritic terrains is discussed in terms of nutrient demand in agriculture. The data presented show a dramatic depletion of virtually all nutrients when compared to crustal levels and other soil systems. Increasing world demand for food production, particularly in tropical countries where alcohol production is also needed, has forced the agriculture frontier deep into lateritic areas. As cultivation is intensified the laterite becomes more barren and a neutral recipient for the massive doses of nutrients that are to be constantly added if production is to continue. Conventi...
Calcite is an efficient and low-cost material to enhance benthic weathering in shelf sediments of the Baltic Sea
Michael Fuhr, Andrew W. Dale, Klaus Wallmann, Rebecca Bährle, Habeeb Thanveer Kalapurakkal, Stefan Sommer, Timo Spiegel, Ryo Dobashi, Björn Buchholz, Mark Schmidt, Mirjam Perner, Sonja Geilert
ABSTRACT:
Recent studies have proposed calcite and dunite as possible alkaline materials for enhanced benthic weathering in shallow depocenters of the Baltic Sea as a marine carbon dioxide removal strategy. In this study, insights on calcite and dunite weathering from laboratory incubations and long-term benthocosm experiments are combined with a numerical box-model to assess the carbon dioxide uptake potential of mineral addition to organic-rich ...
Basalt Rock Dust Amendment on Soil Health Properties and Inorganic Nutrients—Laboratory and Field Study at Two Organic Farm Soils in New England, USA
Justin B. Richardson
ABSTRACT:
Basalt rock dust (RD) is a rock quarry byproduct that may improve soil health in organic farming systems. RD was applied at two contrasting organic farms (the no-till VT-Farm in Thetford, Vermont, and the tilled MA-Farm in Barre, Massachusetts) and in soil batch reactors to investigate the impacts of basalt RD applications (6.7 tons ha−1) on physical and chemical soil health properties. Triplicate soil pits at two fields (RD and no RD) at each farm were sampled down between 80 to 110 cm depths in 2020. Median coarse (>2 mm) and very coarse aggregates (>50 mm) increased by 15% to 25%, and soil organic carbon ...
Soil physicochemical data at Two New England Farms with and without Basalt Rock Dust Application
Justin Richardson
ABSTRACT:
Soil physical and chemical data were collected from Cedar Circle Farm and Education Center in Thetford Vermont and Many Hands Farm in Barre, Massachusetts collected in Spring 2021. At each farm, two field were sampled. One with basalt rock dust application of 1.1 tonnes per hectare and an adjacent field without. Included in this data set are CSV files of: 1) ‘pH’ = Soil pH data for each soil horizon averaged for the three soil pit replicates 2) ‘Texture’ = Soil Texture for select horizons averaged for the three soil pit replicates 3) ‘SOC’ = Soil organic carbon concentrations and pool data for each soil ...
The combination of crushed rock and organic matter enhances the capture of inorganic carbon in tropical soils
F. P. Medeiros, S. H. Theodoro, A. M. X. Carvalho, V. S. Oliveira, L. C. Oliveira
ABSTRACT:
The use of remineralizers (REM) derived from crushed rocks has become an important option to ensure soil fertility and food and nutritional security, as well as a potential mechanism to capture CO2 efficiently, helping to mitigate climate change. The objective of this article is to present the direct and indirect effects of the use of REM in carbon capture processes through accelerated rock weathering. The tests were carried out in leaching columns where a type of rock (R), characterized as kamafugite, was used at a dosage equivalent to 40 t ha-1 incorp...
