Agricultural use of inorganic fertilizers in 2021 was 195 million tonnes of nutrients, of which 56% was nitrogen. [20] Asia represented 53% of the world's total agricultural use of inorganic fertilizers in 2021, followed by the Americas (29%), Europe (12%), Africa (4%) and Oceania (2%). This ranking of the regions is the same for all nutrients.
e. Biodynamic agriculture is a form of alternative agriculture based on pseudo-scientific and esoteric concepts initially developed in 1924 by Rudolf Steiner (1861–1925). [1][2] It was the first of the organic farming movements. [3] It treats soil fertility, plant growth, and livestock care as ecologically interrelated tasks, [4][5][6 ...
History of fertilizer. Global Fertiliser consumption over time. The history of fertilizer has largely shaped political, economic, and social circumstances in their traditional uses. Subsequently, there has been a radical reshaping of environmental conditions following the development of chemically synthesized fertilizers. [1][2][3]
Soil fertility is a complex process that involves the constant cycling of nutrients between organic and inorganic forms. As plant material and animal wastes are decomposed by micro-organisms, they release inorganic nutrients to the soil solution, a process referred to as mineralization.
The zone of n clearance can be clearly seen. Phosphate solubilizing bacteria (PSB) are beneficial bacteria capable of solubilizing inorganic phosphorus from insoluble compounds. [1] P-solubilization ability of rhizosphere microorganisms is considered to be one of the most important traits associated with plant phosphate nutrition.
The industrial revolution introduced inorganic methods, most of which were not well developed and had serious side effects. An organic movement began in the 1940s as a reaction to agriculture's growing reliance on synthetic fertilizers and pesticides. The history of this modern revival of organic farming dates back to the first half of the 20th ...
Calcium cyanamide, also known as Calcium carbondiamide, Calcium cyan-2°-amide or Calcium cyanonitride is the inorganic compound with the formula CaCN 2. It is the calcium salt of the cyanamide (CN2−. 2) anion. This chemical is used as fertilizer [3] and is commercially known as nitrolime.
Phosphorus is found in the soil in both inorganic and organic forms [31] and makes up approximately 0.05% of soil biomass. [34] Phosphorus fertilizers are the main input of inorganic phosphorus in agricultural soils and approximately 70%–80% of phosphorus in cultivated soils is inorganic. [35]
