Abstract

Pepeo se koristi u poljoprivredi od davnina, međutim uslijed modernizacije poljoprivredne proizvodnje i razvoja petrokemijske industrije u posljednjih nekoliko desetljeća još uvijek nije našao širu primjenu u praksi. Povećanjem broja bioelektrana, koje su poticane u svrhu proizvodnje energije iz obnovljivih izvora energije, generiraju se kao nusproizvod i velike količine pepela iz biomase koje je potrebno zbrinuti, odnosno uspostaviti održivo gospodarenje pepelom iz biomase. Kao moguće rješenje se nudi upotreba pepela iz biomase na poljoprivrednim površinama u svrhu kondicioniranja kiselih i fitohranivima osiromašenih tala. U radu je prikazana mogućnost korištenja pepela u svrhu poboljšanja kvalitete tla s fokusom na povećanja prinosa test kulture rotkvice. Istraživanjem se utvrdilo da primjena pepela u masenom udjelu do 1 % u tlu podiže vrijednost pH na optimalnu razinu za potrebe bilinogojstva, te da povećava sadržaj fiziološki aktivnog fosfora i kalija bez negativnih utjecaja na test kulturu.

Abstract (english)

Ash has been used in agriculture since ancient times, however, due to the modernization of agricultural production and development of the petrochemical industry in recent decades has not found wider application in practice. With the increasing number of biofuel power plants that are stimulated for the production of renewable energy, large amounts of biomass ash are generated as a byproduct. The ash needs to be disposed of safely, i.e. a sustainable management of biomass ash needs to be established. A possible solution is the use of ash from biomass on agricultural fields for the purpose of conditioning the acidic and phytonutrient impoverished soils. The paper presents the possibility of using ash for the purpose of improving the soil quality with the focus on increasing the yield of radish. Research has shown that the application of ash of up to 1 % of the soil share raises the soil pH value to the optimum level for the majority of crops, and the application of 1 % ash gives the biggest increase in the physiologically active phosphorus and potassium content without negative chemical changes in the soil.
