Introduction Thefertilizerisanykindofmaterialthatisappliedtosoilortoplanttissues to supply one or more plant nutrients essential to the growth of plants. It may be natural or synthetically produced [1]. Managementofsoilfertilityhasbeenagreatproblemforthefarmersfor thousands of years. Records showed that Egyptians, Romans, Babylonians, and early Germans were using minerals and manure to enhance the productivityoftheirfarms.Themodernscienceofplantnutritionstartedin the 19th century with the work of German chemist Justus von Liebig [1]. The Haber process and the Ostwald process developed in the 1910 and 1920s made a great revolution in the fertilizer manufacturing Industry. Ammonia (NH ) is produced from methane (CH ) gas and molecular 3 4 nitrogen (N ) through the Haber process, which is then converted into 2 nitric acid (HNO ) in the Ostwald process [2]. 3 The nitrogen-based fertilizer production was started with Birkelande Eyde process, which was one of the most competing industrial processes in the nitrogen-based fertilizer production. In this process, the atmospheric nitrogen (N ) is fixed into nitric acid (HNO ) through nitrogen fixation. 2 3 (cid:1) The nitric acid was then used as a source of nitrate (NO ) [3]. 3 Nowadays, it has been estimated that almost half the people on the Earth are currently fed as a result of synthetic nitrogen fertilizer. The development of synthetic fertilizer has significantly supported global populationgrowth[4].Inthelast50years,theuseofcommercialfertilizers has been increasing steadily; reaching almost 100 million tons of nitrogen peryear,anditisestimatedthataboutone-thirdofthefoodproducednow could not be produced without the addition of fertilizers [5]. The use of phosphate fertilizers has also increased from nine million tons per year in 1960 to 40 million tons per year in 2000. Yara International is the world’s largest producer of nitrogen-based fertilizers [6,7].

The nutrient deficiency will result in stunting of plants and that will gradually reduce the yield by slowing down the progress of the growth cycle, causing late fruiting and delayed maturity. The ability of the crop to absorb the nutrients from the soil depends upon the biological activity. Normallythenutrientdeficiencytakesplaceduringthegrowingseasonand dependsonthetemperature andmoisturecontent ofthesoil[8].Fertilizers enhance plant growth traditionally; either as, being additives that provide nutrients or by enhancing the effectiveness of the soil by modifying its water retention and aeration [9]. Also, an important component of the weedmanagementprogramistheefficientandappropriatemanagementof fertilizerintermsofevaluationofbestsourceofnutrients,optimumratesof fertilization, proper timing, and suitable fertilizer placement [3,10]. The essential prerequisite for optimizing nutrient application is the detailed knowledge about the addition of nutrients, i e., the absorption of nutrients by the plants. The applied nutrients should satisfy the plant requirementsandthemethodusedfortheapplicationshouldminimizethe leachingtotheenvironmentandtherebycontroltherateofenvironmental pollution [11]. The type of fertilizer, timing of fertilizer application, and seasonal trends are the major factors that affect the efficiency of the applied N(nitrogen)tosatisfytheNdemandofthecrops[12,13].Theefficiencyof thecropstoabsorbtheNisinfluencedbythesoiltype,cropsequence,and the residual and mineralized N [14]. The reduction of nitrogen loss and increase in the N use efficiency can be improved by numerous strategies. For example, the use of N sources, consumption of slow-release fertilizer, proper placement techniques, and also by the use of N inhibitors [15e17]. The plant metabolism is coupled with the availability of the N sources because it has a fundamental role in the plant metabolism. It is necessary to optimize the management of N resources to the cropping system to increase itsNuseefficiencyandtherebyimprovetheproductivity[18].Normally,this can be achieved either by increasing the production of N in the soil or by increasingtheaccumulationofNcompoundsintheediblepartofthecrop[15]. The nutrients requiredfor healthy plant life are classifiedon thebasis of the elements; but these elements are not used directly as fertilizers. The compounds containing these elements are the basis of fertilizers. The macronutrients are consumed in larger quantities by the plants. They are present in plant tissue in quantities from 0.15% to 6.0% on a dry matter (DM)(0%moisture)basis.Plantsaremadeupoffourmainelementssuchas hydrogen, oxygen, carbon, and nitrogen. Hydrogen, oxygen, and carbon Conventionalmethodsoffertilizerrelease 3 will be available in the form of water and carbon dioxide. The nitrogen is found in the atmosphere as atmospheric nitrogen which is unavailable to plants. So the nitrogen is considered as the most important fertilizer since nitrogen is present in proteins, DNA, and other components such as chlorophyll. Some bacteria and their host leguminous plants can fix atmospheric nitrogen (N ) by converting it to ammonia. Phosphate is 2 required for the production of DNA and ATP, the main energy carrier in cells, as well as certain lipids. The fertilizer contains: (cid:129) Three main macronutrients: ◦ Nitrogen (N): leaf growth ◦ Phosphorus (P): Development of roots, flowers, seeds, fruit ◦ Potassium (K): Strong stem growth, movement of water in plants, promotion of flowering and fruiting (cid:129) Three secondary macronutrients: calcium (Ca), magnesium (Mg), and sulfur (S) (cid:129) Micronutrients: copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn), boron (B). Of occasional significance are silicon (Si), cobalt (Co), and vanadium (V). Micronutrients are required in smaller quantities, in parts-per-million (ppm) and are present at the active sites of enzymes in the plant tissues that carry out the plant’s metabolism [19]. 2. Classification Fertilizers are classified in several ways. 2.1 Based on the nutrient supply On the basis of the nutrient supply, the fertilizers can be classified into straight fertilizers and complex fertilizers. 2.1.1 Single nutrient or straight fertilizers Asthenameindicates,thesinglenutrientorstraightnutrientfertilizersprovide asinglenutrienttotheplants(e.g.,K,P,orN).Ammoniaoritssolutionsarethe widelyusednitrogen-basedstraightfertilizers.Ammoniumnitrate(NH NO ) 4 3 andureaarepopularsourcesofnitrogen.Ureaishavingtheadvantagethatitis solidandnonexplosive,unlikeammoniaandammoniumnitrate. The superphosphates are the main straight phosphate fertilizers. Single superphosphate (SSP) consists of 14%e18% P O , again in the forms of 2 5 4 ControlledReleaseFertilizersforSustainableAgriculture Ca(H PO ) and also phosphogypsum (CaSO4$2H O). The main con- 2 4 2 2 stituentsoftriplesuperphosphate(TSP)are44%e48%ofP O andnogypsum. 2 5 Amixtureofsinglesuperphosphateandtriplesuperphosphateiscalleddouble superphosphate.Mostofthe(morethan90%)typicalsuperphosphatefertilizer iswater-soluble[20]. MuriateofPotash(MOP)isthemainpotassium-basedstraightfertilizer. Muriate of Potash consists of 95%e99% KCl, and is typically available as 0-0-60 or 0-0-62 fertilizer [21]. 2.1.2 Multinutrient or complex fertilizers The multinutrient or complex fertilizers provide two or more nutrients (e.g., N and P). The commonly used fertilizers are the complex fertilizers. Since they consist of two or more nutrient components, they are again classified into binary fertilizers and three-component fertilizers or NPK fertilizers [20]. 2.1.2.1 Binary (NP, NK, and PK) fertilizers Since they provide both nitrogen and phosphorus to the plants they are called NP fertilizers, e.g., monoammonium phosphate (MAP) and dia- mmoniumphosphate(DAP).TheactiveingredientinMAPisNH H PO 4 2 4 andtheactiveingredientinDAPis(NH ) HPO .About85%ofMAPand 4 2 4 DAP fertilizers are soluble in water. 2.1.2.2 NPK fertilizers Nitrogen,phosphorus,andpotassiumcontainingfertilizersarecalledthree- component fertilizers or NPK fertilizers. 2.2 Based on the presence or absence of carbon 2.2.1 Organic fertilizer Organic fertilizers are recycled plant- or animal-derived matter. 2.2.2 Inorganic fertilizer Inorganic fertilizers or synthetic fertilizers are synthesized by various chemical treatments [20]. 3. Mode of application Theapplicationratesoffertilizerdependonthesoilfertility.Thefertilityof a soil is usually as measured by a soil test according to the particular crop. The method of applying fertilizers depends on the nature of crop plants, their nutrient needs, and the soil (Table 1.1). Table1.1 Acomparisonofdifferent methodsoffertilizerapplication.
