Economic and Financial Analysis of Tree Seedling Production Using Composted Biosolids Substrate

ABSTRACT The aim of this study was to evaluate production profitability of Croton urucurana and Cytharexyllum myrianthum seedlings produced in substrates composed of mixtures of composted biosolids and carbonized rice husk in different concentrations of nutrient solution. Seedlings were subjected to three doses of fertigation solutions. In order to check quality standards which indicated production cycle, the height, stem diameter and root quality were evaluated. Economic viability was determined by indicators of economic attractiveness commonly used for investment projects. Production costs o...
