In plants, potassium and nitrogen are the two elements required in greatest amounts, while in animals and humans potassium is the third most abundant element, after calcium and phosphorus. Without sufficient plant and animal intake of potassium, life as we know it would cease. Human and other animals atop the food chain depend upon plants for much of their nutritional needs. Many soils lack sufficient quantities of available potassium for satisfactory yield and quality of crops. For this reason available soil potassium levels are commonly supplemented by potash fertilization to improve the potassium nutrition of plants, particularly for sustaining production of high yielding crop species and varieties in modern agricultural systems.

A strict distinction between these materials is not always possible, and also a generally accepted terminology is lacking. However, research on both materials is increasingly overlapping: sorption and remediation are the domain of activated carbon, which nowadays is also addressed by studies on biochar. Thus, awareness of both fields of research and knowledge about the distinction of biochar and activated carbon is necessary for designing novel research on pyrogenic carbonaceous materials. Here, we describe the dividing ranges and common grounds of biochar, activated carbon and other pyrogenic carbonaceous materials such as charcoal based on their history, definition and production technologies.

    MORDANTING NATURAL DYES IRON SULPHATE (Ferrous Sulphate) is usually used to change the colour of a dye. It also makes natural dyes Most natural dyes have great affinity for fibre but more light and wash fast. More often used with cellulose poor light and wash fastness. If the fibre is pre than protein as it can make protein fibres brittle and harsh. mordanted you create a bond between the dye Iron changes shades to deeper, darker shades and is better and the fibre which will improve this dramatically. used in a premordant bath than directly into the dyebath.
