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...

Effect of the addition of granitic powder to an acidic soil from Galicia (NW Spain) in comparison with lime

Benita Silva, Remigio Paradelo, Nuria Vázquez, Eduardo García-Rodeja, María Teresa Barral ABSTRACT: High amounts of granitic powders are produced in the granite industry in Galicia (NW Spain), whose accumulation could pose environmental threats, at least locally. Due to its natural alkalinity, the powder could be used to correct the acidity of soils or mining residues, where it would act at the same time as a source of plant nutrients. A greenhouse experiment was conducted to test the growth of Italian ryegrass on an acid soil amended with different rates of granitic powder (2.5, 5 and 10 %). Soil amended with lime or with lime in combination ...

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...

The potential for glacial flour to impact soil fertility, crop yield and nutrition in mountain regions

Sarah Tingey, Jemma L. Wadham, Jonathan Telling, Shannon Flynn, Jonathan R. Hawkings ABSTRACT: Novel sustainable agricultural strategies that enhance soil nutrients and human nutrition are crucial for meeting global food production needs. Here, we evaluate the potential of "glacial flour," a naturally crushed rock produced by glaciers known to be rich in nutrients (P, K, and micronutrients) needed for plant growth. Our proof-of-concept study, investigated soybean (<i>Glycine max.</i> var. Black jet) growth, yield, and nutrient content with soil supplementation from glacial flour sourced from Himalayan glaciers (meta-sediment gneiss ...

GEMAS: Boron as a geochemical proxy for weathering of European agricultural soil

Philippe Négrel, Anna Ladenberger, Alecos Demetriades, Clemens Reimann, Manfred Birke, Martiya Sadeghi ABSTRACT: About a century ago, B was recognised as an essential element for the normal growth of plants and terrestrial organisms. Limitations for plant development have been recognised in agricultural systems, particularly in highly weathered soil. Boron is rarely analysed in whole rock or soil analysis, as it requires specific analytical techniques. It is often determined, after partial extraction (aqua regia or CaCl), usually on a limited number of samples. Many more questions than answers exist about the environmental behaviour of B. We ...

Origin of the silicic volcanic rocks of the Early Permian Panjal Traps, Kashmir, India

J. Gregory Shellnutt, Ghulam M. Bhat, Kuo-Lung Wang, Michael E. Brookfield, Jaroslav Dostal, Bor-Ming Jahn ABSTRACT: The Panjal Traps of Kashmir, India represent a significant outpouring of mafic and silicic volcanic rocks during the Early Permian and are synchronous with the opening of the Neotethys Ocean. Previous studies have suggested that the silicic volcanic rocks are derived by differentiation of mafic magmas. Dacites and rhyolites collected from the lower portions of the volcanic pile near Pampore, Kashmir are peraluminous (ANCK>1.0) in composition. Their calculated whole rock ISr values are variable (ISr=0.69307 to 0.71825) and ...
