Nitrogen-containing fertilizers can cause soil acidification when added. Accumulation of toxic elements[ edit ] Cadmium[ edit ] The concentration of cadmium in phosphorus-containing fertilizers varies considerably and can be problematic.
Continuous use of high-cadmium fertilizer can contaminate soil as shown in New Zealand  and plants. Consequently, the widespread use of phosphate fertilizers has increased soil fluoride concentrations.
The most common toxic elements in this type of fertilizer are mercury, lead, and arsenic. Highly pure fertilizers are widely available and perhaps best known as the highly water-soluble fertilizers containing blue dyes used around households, such as Miracle-Gro.
These highly water-soluble fertilizers are used in the plant nursery business and are available in larger packages at significantly less cost than retail quantities.
Some inexpensive retail granular garden fertilizers are made with high purity ingredients. Trace mineral depletion[ edit ] Attention has been addressed to the decreasing concentrations of elements such as iron, zinc, copper and magnesium in many foods over the last 50—60 years.
In Western Australia deficiencies of zinccopper, manganeseiron and molybdenum were identified as limiting the growth of broad-acre crops and pastures in the s and s. The effects can be Indian fertilizer market into an equivalent amount of carbon dioxide.
The amount varies according to the efficiency of the process. The figure for the United Kingdom is over 2 kilogrammes of carbon dioxide equivalent for each kilogramme of ammonium nitrate. Atmosphere[ edit ] Global methane concentrations surface and atmospheric for ; note distinct plumes Through the increasing use of nitrogen fertilizer, which was used at a rate of about million tons of N per year in  adding to the already existing amount of reactive nitrogen, nitrous oxide N2O has become the third most important greenhouse gas after carbon dioxide and methane.
It has a global warming potential times larger than an equal mass of carbon dioxide and it also contributes to stratospheric ozone depletion. These emissions contribute to global climate change as methane is a potent greenhouse gas.
InChinese governments have started to partially withdraw fertilizer subsidies, which also include contributions to fertilizer transportation, electricity and natural gas use in the industry. Because of this, professional farmers who run large-scale farms have already used less fertilizers since then under the fertilizer prices went up.
If large-scale farms keep reducing their use of fertilizer subsidies, they have no choice but to optimize the fertilizer they have which would therefore gain an increase in both grain yield and profit.
The former encourages soil fertility using local resources to maximize efficiency. Organic agriculture avoids synthetic agrochemicals. Conventional agriculture uses all the components that organic agriculture does not use. History of fertilizer Management of soil fertility has been the preoccupation of farmers for thousands of years.
Egyptians, Romans, Babylonians, and early Germans all are recorded as using minerals and or manure to enhance the productivity of their farms. John Bennet Lawesan English entrepreneurbegan to experiment on the effects of various manures on plants growing in pots inand a year or two later the experiments were extended to crops in the field.
One immediate consequence was that in he patented a manure formed by treating phosphates with sulfuric acid, and thus was the first to create the artificial manure industry. In the succeeding year he enlisted the services of Joseph Henry Gilbertwith whom he carried on for more than half a century on experiments in raising crops at the Institute of Arable Crops Research.
A factory based on the process was built in Rjukan and Notodden in Norway, combined with the building of large hydroelectric power facilities.

They typically provide 6 to 16 weeks of delayed release in turf applications. When a hard polymer is used as the secondary coating, the properties are a cross between diffusion-controlled particles and traditional sulfur-coated.The Vice President of India, Shri M.
