#plant nutrition

• Aerophyte — As a noun, it designates a plant (or vegetable organism) that extracts its water and nutrients directly from the air, atmospheric moisture, or precipitation, without having direct contact with the soil. Many of these plants are epiphytes (such as certain bromeliad or orchid species) and use trees merely as structural support, not as a food source. As an adjective, it describes the quality of a plant belonging to this ecological type.
• Agrochemistry — A branch of applied chemistry and agronomy that studies the chemical and biochemical processes in soil and plants, the relationships between plants, soil, and fertilizers, as well as the methods of utilizing chemical substances in agriculture. This science provides the theoretical framework for optimizing plant nutrition, systematically increasing crop yields, and preventing environmental chemical pollution.
• Agrology — A branch of agronomy and soil science that deals with the study of the structure, composition, and properties of soils in direct relation to the nutrition, development, and productivity of cultivated plants. This discipline analyzes land fertility and provides the scientific foundation for applying soil improvement, liming, and rational cultivation techniques.
• Agronomy — An applied science that studies the totality of biological laws, technical methods, and economic procedures governing the proper cultivation of crops, enhancement of soil fertility, and increase of field productivity. This discipline integrates knowledge from biology, chemistry, soil science, meteorology, and economics to ensure efficient agricultural management.
• Ammophoska — A complex and ternary mineral chemical fertilizer, obtained by adding potassium salts to the basic composition of ammophos. This fertilizer contains all three essential macroelements for plant growth (nitrogen, phosphorus, and potassium - NPK), providing a complete nutrition and being widely used for fertilizing intensive crops of vegetables, fruit trees, or grapevines.
• Azotobacter — A genus of aerobic, motile, oval or spherical bacteria that live freely in the soil and possess the remarkable capacity to fix molecular atmospheric nitrogen directly into organic compounds assimilable by plants, without establishing a symbiotic relationship with their roots; it is widely used in bio-agriculture as a biofertilizer to stimulate soil fertility.
• Azotobacterin — A bacterial preparation or biological fertilizer produced from pure cultures of Azotobacter chroococcum or other bacteria capable of fixing molecular nitrogen from the atmosphere. It is applied to seeds or directly into the soil to improve plant nitrogen nutrition, stimulating rhizosphere biological activity and increasing crop yields without synthetic chemical inputs.
