From wastes to resources: citrus hydrolatesas natural biostimulants of soil microorganisms
The hydrolates result from the industrial extraction process of the essential oils through cold pressing of the citrus peels. Today, they are considered a waste to be disposed of. However, due to the presence of water soluble compounds (sugars, polyphenols, acids), hydrolates could be reused instead of being, due to the high economic burden, a problem in the disposal of the same, charged to the company.The aim of this work was to evaluate the effects of citrus hydrolate when directly applied as irrigation water on soil microbial biomass, activity and structure community. The soil used for the experiment was collected from the topsoil (0-10 cm) of a citrus orchard, air-dried and sieved at 2 …
Monitoring of the effects of added carbon by citrus hydrolates waste in a soil.
The hydrolates are the waste to be disposed of are a product of the industrial extraction process of the essential oils through cold pressing of the citrus peels. However, due to the presence of water soluble compounds (sugars, polyphenols, acids), hydrolates could be reused instead of being, due to the high economic burden, a problem in the disposal of the same, charged to the company. The aim of this work was to evaluate the effects of citrus hydrolate when directly applied as irrigation water on soil. Was monitored soil chemical and biochemical property, in particularly effect of the high carbon addition on microbial biomass, activity and structure community and effect on carbon soil sto…
PHYTOTOXIC POTENTIAL EFFECT OF EUCALYPTUS ESSENTIAL OILS FOR WEED CONTROL
The widespread use of synthetic herbicides has resulted in herbicide-resistant weeds, disturbed ecological balance and negative effects on human health. Due to this fact, it is necessary to rely on alternative weed control strategies using natural compounds released by plants, as essential oils (EOs), since they have a short half-life as they are biodegradable, and safer than synthetic compounds, with little damage to the environment, without even contaminating ground water (Topal and Kocaçalıskan 2006). Essential oils from different species contain allelochemical compounds that possess significant phytotoxic activity. Azizi and Fuji (2006) demonstrated that Eucalyptus (family Myrtaceae) EO…
