Preliminary studies on the selection and preparation of substrates for culture in pots and containers

Abstract

The paper presents a study on the main pedological, agrochemical and biological indices of the different types of substrate used for growing vegetables in pots and containers in order to optimize the growth and development of plants. The researchewere carried out in an experimental field set up at the Didactic Center of the University of Agricultural Sciences and Veterinary Medicine Iasi. Three types of substrate were used: S1 -substrate made from 35% garden soil, 35% compost, 20% peat, 10% sandand pearlite, S2-substrate made of earth 35% garden, 20% compost, 35% peat, 10% sand and pearlite; S3 -commercially available substrate. Determinations havebeen made on:nutrients, pH, humidity and granulometry. Substrate quality assessment was performed on the basis of yield and harvest quality
