Summary
Studies on the effects of biosolids (BS) amended substrate on food quality and safety in tomato production have not been adequately addressed. The objective of this study was to investigate the influence composted BS and NPK fertilizer in forest soil on post-harvest quality and safety of potted greenhouse tomatoes. Potted tomatoes ‘Maxim F1’were grown in a randomized complete block design with four replications. Inorganic fertilizer NPK fertilizer was applied at 0, 100 and 200 kg ha-1; BS was applied at 0%, 10%, 20%, 30%, and 40% v/v, in all possible combinations. Tomato were harvested and analyzed for ascorbic acid, chlorophylls, carotenoids and total phenolic compounds; weight loss, fruit firmness, titratable acidity and total soluble solids, as well as heavy metals and microbial contami
