Abstract
Fosfor je element koji se pojavljuje kako u organskom tako i u anorganskom obliku, te je element biljne ishrane. Kao takav može potjecati iz minerala Zemljine kore te kao produkt razgradnje žive ili organske tvari. Ciklus fosfora u tlu sastoji se iz razgradnje fosfornih spojeva u tlu, njihovog usvajanja biljkama i ponovnog nastanka minerala tla. Sadržaj organske frakcije fosfora značajno ovisi o tipu tla, te pH vrijednosti tla. Mikroorganizmi koji imaju sposobnost oslobađanja fosfata, odnosno oslobađaju fosfor iz anorganskih spojeva, primjerice iz kalcijevog fosfata, nazivaju se fosfomobilizatori. Kakva će biti brojnost i zastupljenost ovisi o utjecaju ekoloških faktora, antropogeno djelovanje, tipa vegetacija i međusobnih odnosa unutar mikrobne populacije tla. Bakterije koje sintetiziraju fosfataze (Bacillus, Pseudomonas) naseljavaju korijen biljaka i značajno utječu na mineralizaciju organskih spojeva fosfora na njegovoj površini i mogu se koristiti u poljoprivrednoj proizvodnji kao zamjena fosfornih mineralnih gnojiva.
Abstract (english)
Phosphorus is an element that occurs in both the organic and the inorganic form, and as a plant nutritient element. As such it can be derived from the minerals of the Earth's crust, and as a product of the composition of organic or living matter. Cycle of phosphorus in the soil consists of the decomposition phosphorous compounds in soil, their plant asimilation and re-occurrence of minerals in soil. The content of the organic fraction of phosphorous significantly depends on the type of soil and their pH soil value. Microorganisms that have abillity to release phosphate, or releasing phosphorus from inorganic compounds, such as calcium phosphate, are called phosphorous mobilizing bacteria. What will be the representation number depends on the impact of environmental factors, anthropogenic activity, type of vegetation and relationships within the microbial population of the soil. Bacterica which synthesize phosphatase ( Bacillus, Pseudomonas) inhabited by root and significantly affect the mineralization of organic compound of phosphorous on the surface and can be used in agriculture as a substitute phosphorous fertilizers. Analysis of plant available phosphorous is obligate chemical analysis of soil fot the assessment of soil fertility and fertilizer recommendatitons, and in Republic of Croatia in use is the most common method AL.
