Abstract Natural dyes are compounds that occur naturally in several organisms and are classified based on chemical structure and application method. The literature cites several natural dyes used in industrial transformation processes. Annatto dye is used in the food industry, and its biological pigment is extracted from the annatto seed. However, this

Potassium Deficiency and Hormone Signalling in Plants
ABSTRACT Potassium (K or K⁺) is a vital macronutrient that influences numerous physiological processes related to plant physiology and development. Recently, there is a growing focus on enhancing K+‐use efficiency (KUE) to ensure optimal plant growth, especially in K+ deficient soils.

Potash prices are skyrocketing and may soar to $1,000 or more per ton by the end of 2008 (Figure 1). Rapidly rising demand for fertilizer and limited expansion of production are leading causes of the increase (Sergeant, 2008).

On the features of the formation of potassium salts deposits of Precarpathia
The Precarpathian salt deposits are strongly dislocated, and in this, in our opinion, it is necessary to look for the reason for brecciation. The main phase of rock transformation is obviously connected to the stage of tectonic activation.

SIR EDWARD THORPE'S lucid review of the known geological sources of potash (NATURE, January 3) is of absorbing interest to agriculturists, whose industry must be seriously affected by any permanent stinting in the supply of this indispensable fertiliser, entailing a corresponding diminution in the production of root crops.
