Macro and Microelements in Leaves of ‘Meredith’ Peach Cultivar Supplied with Biochar, Organic and Beneficial Biofertilizer Combinations

The content of macro and microelements in the leaves peach trees treated with biochar, organic fertilization microorganisms field experiment was tested. carried out accordance integrated fruit production methods at NIHR Experimental Orchard Dąbrowice, from 2015 to 2017. were grafted on P. persica Mandżurska rootstock planted spring 2013. In 2014, following products applied around mixed into topsoil: biochar a dose 1.6 kg/tree (2000 kg/ha); used together microorganisms—bacteria Pseudomonas fluorescens, Pantoea arbuscular mycorrhizal fungi—Glomus caledonium, Glomus intraradices coronatum; Florovit NPK fertilizer 0.2 kg/tree; NPK; same microorganisms; an untreated control. average results showed that, compared control, increased nitrogen by 6%. All experimental combinations P K leaves. most effective increasing phosphorus leaves—by 48%—was Florovit. greatest increase potassium after use Florovit—by 38%. magnesium ranged 0.49 0.59 g/100 g DW. highest Mg found application Florovit, lowest alone. fertilized had calcium content, while combination only. alone did not boron all other combinations, higher amount found. highest—18% more than control this microelement where used. Trees accumulated least copper leaves, element Lower iron concentrations as result applying microorganisms, relative combination. only soil manganese zinc accumulation favored general, studies have shown that small or is very method feeding trees. More research needed their various orchard fertilization.
