Flower species suitable for growing on acidic soils

pH reakcija tla pokazatelj je niza agrokemijskih svojstava tla važnih za uzgoj, rast i razvoj cvjetnih vrsta kao i visinu i kakvoću prinosa svih ostalih biljnih vrsta. U cvjetnoj kao i u poljoprivrednoj proizvodnji ovaj pokazatelj može biti limitirajući čimbenik. Ovisno o pH vrijednosti tla biljne vrste su podijeljene u tri skupine: acidofilne, neutrofilne i alkalofilne. pH reakcija tla potrebna za rast i razvoj promatranih cvjetnih vrsta kreće se između 6 i 7,9, što znači da promatrane cvjetne vrste najbolje uspjevaju na slabo kiselim i alkalnih tlima. Aktualna kiselost ili alkalnost tla određuje se elektrometrijski (pH-metrom) u vodenoj suspenziji tla, za gradaciju kiselosti, odnosno alkalnosti. Pri odabiru cvjetnih vrsta potrebno je voditi računa o pH reakciji tla jer neodgovarajuće tlo ili cvjetna vrsta rezultirati će lošim izgledom i propadanjem biljaka. Cvjetne vrste opisane u radu zahtjevaju kiselu pH reakciju tla i uspješno se uzgajaju na istim uz različite karakteristike svojstvene svakoj cvjetnoj vrsti.The pH reaction of the soil is an indicator of a number of agrochemical properties of the soil important for the cultivation, growth and development of flower species as well as the height and quality of yield of all other plant species. In flower production as well as in agricultural production this indicator can be a limiting factor. Depending on the pH value of the soil, plant species are divided into three groups: acidophilic, neutrophilic and alkalophilic. The pH reaction of the soil required for the growth and development of the observed flower species ranges between 6 and 7.9, which means that the observed flower species thrive best on weakly acidic and alkaline soils. The actual acidity or alkalinity of the soil is determined electrometrically (pH-meter) in an aqueous suspension of the soil, for the gradation of acidity or alkalinity. When choosing flower species, it is necessary to take into account the pH reaction of the soil because unsuitable soil or flower species will result in poor appearance and decay of plants. The flower species described in the paper require an acidic pH reaction of the soil and are successfully grown on the same with different characteristics inherent in each flower species
