Evaluation of the possibility of using apple pomace for fertilizing purposes
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 4
Abstract
This work presents the results of research on the physical and chemical properties of apple pomace. Laboratory tests included the analysis of water content, sodium, potassium, calcium and magnesium cations as well as phosphorus, nitrogen and carbon. Apple pomace was obtained from two plants (A and B) producing apple juices. Both plants are located in north-eastern Poland, Podlasie province. Plant A is engaged in fruit and vegetable processing, while plant B in a fruit juice pressing. Based on the obtained results, it was found that the physical and chemical properties of apple pomace differ from each other, and the quality of the raw material, species and variety of apples as well as habitat conditions may influence it. Examining the fertilizing properties, it was found that the ratio of carbon to nitrogen (C: N) can be very diverse (from 5 to 22). However, the analysis of selected parameters indicates that apple pomace can be used for fertilizing purposes, primarily as a substrate for the production of compost.
