Nitrogen loss inhibitors in intensively managed winter wheat
… steps in one or more of these loss pathways. Ammonium polyphosphate, ammonium thiosulfate, dicyandiamide, potassium chloride, and monoammonium phosphate were chosen for use in the present study. They were mixed, singly and in combinations, with UAN solution or urea solution and spring …

Effect of fertilizers and adjuvants on quizalofop, sethoxydim, and thiameturon foliar uptake and weed control
Combinations of urea ammonium nitrate (UAN), ammonium polyphosphate (APP), ammonium sulfate (AS), petroleum oil concentrate (POC), and non-ionic surfactant (SURF) were evaluated as postemergence spray additives to improve giant foxtail (Setaria faberi Herrm.) and volunteer corn (Zea mays L.) …

A study of the thermal degradation of flexible tdi-based polyurethane foams
… degradation processes a more complicated task. Ammonium polyphosphate (APP) has been shown to be an effective fire retardant, altering the degradation mechanisms of the foam and promoting char formation. The addition of vermiculite into the foam has been shown to have little effect on the fire …

Evaluation of Nitrogen Sources, Starter Fertilizers, and Amendments for No-Till Corn Production
… 6 bu acre$\sp{-1}$ lower than the nonvolatile ammonium nitrate source, and 4 bu lower than unamended anhydrous ammonia. Positive grain yield responses to the urease inhibitor, NBPT, were location specific and highly dependent on climatic conditions conducive to N volatilization. Adding NBPT to …

Formulation and Burning Behaviour of Fire Retardant Polyisoprene Rubbers
… Intumescent formulations were prepared using ammonium polyphosphate (APP), pentaerythritol and melamine, and separately using expandable graphite (EG). Within the cone calorimeter both systems yielded a significant reduction in the first peak of heat release rate, but a much higher second peak …

Development of fire retardant timber treatments
… were effective enough to be used commercially. Ammonium hypophosphite increased the residue yield of timber and was shown to operate via both condensed and gas phase fire retardancy mechanisms. A low melting glass formed a gel-like barrier on the surface of the char, but its melting point was …

Characterisation of Halogen Free Fire Retardant Polypropylene Composites Reinforced by Short Natural Fibres
… properties of the composites. Use of intumescent ammonium polyphosphate (APP) in composites has substantially addressed this issue due to its inherent intumescent properties and is an effective way to improve flame retardance of natural fibre composites. However, the widely available different …

Effects of Wool Fibres on Mechanical and Flammability Characteristics of Wool-Polypropylene Composites
… composites through the addition of wool and ammonium polyphosphate (APP) has been confirmed by flammability tests. In particular, cone calorimeter and vertical burn tests have exhibited a significant decrease in peak heat release rate (PHRR) and a direct flame self-extinguishment of …

Improved agronomic management of corn and soybean to increase productivity
… N application was 180 lbs N acre-1 as 32 % urea ammonium nitrate (UAN). Both the N timings were evaluated with four different placements of P utilizing ammonium polyphosphate (10-34-0) either as: none, 20 lbs P2O5 acre-1 in-furrow, 40 lbs P2O5 acre-1 2x2 band, or 60 lbs P2O5 acre-1 via 20 lbs …
