ammonium nitrate (an)
Replicate plots on a clay loam grassland were fertilised with ammonium sulphate (AS), urea (U), calcium nitrate (CN), ammonium nitrate (AN), or cattle slurry supplemented with AN on three occasions in each of 2 years.
      
Applying DCD to ammonium nitrate (AN) fertilised grassland did not reduce emissions after the April 1993?fertilisation, but emissions following the August application were reduced.
      
This study characterized soil chemical and microbiological properties in hay production systems that received from 0 to 600?kg plant-available N (PAN) ha-1 year-1 from either swine lagoon effluent (SLE) or ammonium nitrate (AN) from 1999 to 2001.
      
Urea (U) and ammonium nitrate (AN) had been applied to a Scots pine (Pinus sylvestris L.) forest in northern Sweden for 18 consecutive years at four doses resulting in total N applications ranging from 0 to 1980 kg ha-1.
      
Application of AA with either opener resulted in grain yields and protein contents comparable to granular urea and ammonium nitrate (AN) fertilizers.
      
Ammonium nitrate (AN) was applied as a split application, with 20% preplant and 80% applied every-other week in five equal applications.
      
When applied at a normal rate equivalent to 1,685 kg/ha of 10-15-15-1.2 the blended fertilizer containing urea N did not significantly reduce the tuber yield compared to ammoniated fertilizer and blended fertilizer containing ammonium nitrate (AN).
      
The fertilizer consisted of two types of granules, one containing 80% urea and 20% filler and the second containing 48% ammonium nitrate (AN), 16% ammonium sulphate (AS) and 36% filler.
      
Urea (UR) or ammonium nitrate (AN) fertilizers were surface-applied annually at rates of 20, 100, 180, and 260 kg N ha-1 split into three applications from mid-spring to early fall.
      
The reason for the special thermal behaviour of ammonium nitrate (AN) has been examined.
      
Results of testing the liability of various samples of fertilizer grade ammonium nitrate (AN) to self-heating are presented.
      
The thermal ignition behaviour of various mixtures of organic fuels, magnesium and ammonium nitrate (AN) has been examined by differential thermal analysis technique.
      
Dried samples of ammonium nitrate (AN) containing 1, 3, 5 mol% KNO3, RbNO3 and CsNO3 were investigated with temperature resolved X-ray diffraction.
      
Modification of the room temperature phase (IV-III) of ammonium nitrate (AN) has been attempted using a variety of potassium salts namely, KF, KCl, KI, KNO3, K2CO3, K2SO4, KSCN and K2Cr2O7.
      
High-resolution thermogravimetry was used to study the thermodesorption of octane from ammonium nitrate (AN) prills with different porosities.
      
The main component of an emulsion explosive is a water-in-oil emulsion consisting of a supersaturated ammonium nitrate (AN) water phase, finely dispersed in an oil phase.
      
The effect of sulfur (S) placement and S rate on the efficiency of urea (U) relative to ammonium sulfate (AS) and ammonium nitrate (AN) for cotton were examined in a pot experiment using sandy clay loam soil (pH 7.9).
      
Utilization of15N fertilizers by saplings after the first and second growing seasons following fertilization was greatest with nitrate labelled ammonium nitrate AN-15, and nearly equal for urea U-15 and ammonium labelled ammonium nitrate A-15.
      
Nitrogen was applied as ammonium nitrate (AN) at a rate of 23?kg N ha-1 in 1989 and as urea ammonium nitrate (UAN) at an average annual rate of 50?kg N ha-1 from 1990 to 2003 for both NT treatments.
      
Soils (0-7.5?cm depth) were sampled in March 2004 from the field plots planted with bermudagrass and tall fescue that received 0-600?kg plant available N (PAN)?ha-1?year-1 of SLE or ammonium nitrate (AN) from 1999 to 2001.
