EFFECT OF K-FELDSPAR ROCK FERTILIZER ON GROWTH AND MINERAL CONTENT OF MORINGA SEEDLINGS (MORINGA OLEIFERA) [PDF]
A field experiment was conducted at the Botanical Gardens Research Department Land, Hort. Res. Inst. Alex., Egypt,during 2011-2012 and 2012-2013 seasons to study the effect of Kfeldspar rock fertilizer on growth and mineral content of Moringa seedlings ...

On the relationship between K concentration, grain size and dose in feldspar [PDF]
Previous work has been unable to establish a relationship between K concentration and De in single-grains of feldspar. Here we use four well-bleached sediments with low external dose rate (typically =1.5 Gy ka-1) to investigate this relationship.

Bleachability of pIRIR signal from single-grain K-feldspar [PDF]
The high-temperature (e.g., >200 °C) post-infrared infrared (pIRIR) stimulated luminescence of feldspar has been widely used for dating, because it usually suffers negligibly from anomalous fading.

Bleaching of the post-IR IRSL signal from individual grains of K-feldspar: Implications for single-grain dating [PDF]
Post-IR IRSL (pIRIR) signals from K-feldspar grains measured at elevated temperatures are increasingly being used for dating sediments. Unfortunately the pIRIR signal from K-feldspars bleaches more slowly than other signals (e.g.

Electrostatic K-Feldspar/Na-Feldspar and Feldspar/Quartz Separation: Influence of Feldspar Composition [PDF]
This paper aims at contributing to the possibility of electrically separating K-feldspar/Na-feldspar and quartz/feldspar, investigating the behaviour of mixtures composed of K-feldspar, Na-feldspar and quartz concentrates.

Characterization of potassium solubilizing bacteria isolated from corn rhizoplane
Potassium is one of the most important elements in plant growth and development. Most of the potassium reserves on Earth are in insoluble mineral form, which represents a limitation for the absorption of this nutrient by plants.

Rubidium-rich feldspars and associated minerals from the Luolamäki pegmatite, Somero, Finland [PDF]
Rubidium feldspar occurs near the core zone of the highly fractionated petalite-subtype Luolamäki granitic pegmatite in intimate intergrowth with other feldspars which are part of a characteristic sequence of alteration of pollucite.
