Kompiziti na bazi sirovog fosfata kao prirodna đubriva i remedijacioni agensi

Abstract

Naša istraživanja su bila usmerena ka dizajniranju novog multifunkcionalnog materijala na bazi sinergističkog dejstva sirovog fosfata i modifikovanog zeolita amonijum jonima i otpadne biomase, u cilju povećanja fosfo-mobilizacije u različitim tipovima zemljišta i širokom opsegu pH vrednosti Efikasnost je ispitana na vegetacionom ogledu sa biljkama kukuruza u polukontrolisanim uslovima , na tipu zemljišta, distrični kambisol. Rezultati ukazuju da dodavanje modifikovanog zeolita i pepela koštica višnji, prirodnom fosfatu, doprinosi rastu, razvoju i povečanju prinosa ispitivane kulture. Otpušteni fosfatni joni imali su dvostruku ulogu kao donor hranljivih materija i remedijacioni agens mehanizmom fosfatno -indukovane stabilizacije teških metala. Rezultati ukazuju da kompozit NH4+ - zeolit/prirodni fosfat ima multifunkcionalna svojstva pogodna za u održivoj poljoprivredi.

Our investigation is focused on the design of novel multifunctional material based on the synergistic conjunction of raw phosphate, zeolites modified with ammonium ions and waste biomass, in support to increase phospho-mobilization in various soil types and wider pH range. The results of the vegetation experiment in semi-controlled conditions with maize on soil type distric cambisol indicates that the addition of modified zeolite and ash pit cherries to the rock phosphate favors the growth of the culture and its yield. Released phosphate ions have a dual role as donor of nutrients, and soil remediation amendment through phosphate-induced stabilization of heavy metals. The field vegetation experiment with maize on soil type leached chernozem showed that NH4+-zeolite/raw phosphate composite has multifunctional properties applicable in sustainable agriculture.
