Phosphorus

Business / Agriculture / Phosphorus: An essential nutrient for plants and animals that is commonly applied to crops as a phosphate fertilizer. Phosphorus can contribute to the eutrophication of lakes and other water bodies. Sources of excess phosphorus include sewage and agricultural runoff.

Phosphorus (P)

Science / Periodic Table of Elements / Phosphorus (P): Atomic number: 15, Atomic mass: 30,9738 g.mol -1, Oxidation states: ± 3, 4, 5, Electronegativity: 2,1, Density: 1,82 g/ml at 20°C, Melting point: 44,2 °C, Boiling point: 280 °C, Vanderwaals radius MORE

Eutrophication

Business / Agriculture / Eutrophication: The process by which a body of water acquires a high concentration of plant nutrients, especially nitrates or phosphates. This nutrification promotes algae growth that, when it dies, can lead to the d MORE

Biochemical Cycle

Science / Biology / Biochemical Cycle: The flow of an element through the living tissue and physical environment of an ecosystem; e. g., the carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus cycles. MORE

Primary Macronutrients

Science / Biology / Primary Macronutrients: Elements that plants require in relatively large quantities: nitrogen, phosphorus, and potassium. MORE

Nutrient Pollution

Business / Agriculture / Nutrient Pollution: Contamination by excessive inputs of nutrient: a primary cause of eutrophication of surface waters, in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. Sources of nutrie MORE

Organophosphates

Business / Agriculture / Organophosphates: Insecticides that contain phosphorus, carbon, and hydrogen. They are cholinesterase inhibitors: some are highly acutely toxic, but they usually are not persistent in the environment. Parathion is an e MORE
