Nutrient Sensing and Signaling: NPKS

Annual Review of Plant Biology, 2007
Plants often grow in soils that contain very low concentrations of the macronutrients nitrogen, phosphorus, potassium, and sulfur. To adapt and grow in nutrient-deprived environments plants must sense changes in external and internal mineral nutrient concentrations and adjust growth to match resource availability.

Drum granulation of NPK fertilizers

Powder Technology, 2000
Nitrate-based NPK fertilizer was granulated in a bench scale drum granulation unit. The initial fertilizer possessed a particle size distribution similar to those in industrial granulation units. In this work, three factors are identified affecting the degree of fertilizer granulation, these are solution to solid phase ratio, the binder viscosity and ...

Uvođenje čistije proizvodnje na postrojenjima NPK-1 i MAP/NPK-2

2002
U Petrokemiji se proizvode NPK gnojiva na dva postrojenja NPK-1 i MAP/NPK-2. Nakon provedene analize oba procesa predložene su mjere čistije proizvodnje prema slijedećim kriterijima: A) mjere koje ne zahtijevaju investicije B) mjere čiji se povrat investicija očekuje unutar 6 mjeseci C) mjere koje zahtjevaju veće investicije i čiji se ...

Caking Processes in Granular NPK Fertilizer

Industrial & Engineering Chemistry Research, 1998
This investigation into the caking of granular NPK fertilizer examines three specific areas, namely, accelerated caking tests, the role of unbound water, and the effect of ammonium chloride on caking. The caking propensity of granular fertilizer was characterized by two accelerated caking tests, with the caking propensity being correlated with the ...
