	%X Degradation of agricultural soils has increased rapidly
during the last 20 years due to the indiscriminate use of pesticides
and other anthropogenic activities. Currently, there is an urgent need
of soil restoration to increase agricultural production. Utilization of
sewage sludge or municipal solid waste is an important way to
recycle nutrient elements and improve soil quality. With these
amendments, nutrient availability in the aqueous phase might be
increased and production of healthier crops can be accomplished.
This research project aimed to achieve sustainable management of
tropical agricultural soils, specifically in Puerto Rico, through the
amendment of water treatment plant sludge’s. This practice avoids
landfill disposal of sewage sludge and at the same time results costeffective
practice for recycling solid waste residues. Coriander
sativum was cultivated in a compost-soil-sludge mixture at different
proportions. Results showed that Coriander grown in a mixture of
25% compost+50% Voladora soi+25% sludge had the best growth
and development. High chlorophyll content (33.01 ± 0.8) was
observed in Coriander plants cultivated in 25% compost+62.5%
Coloso soil+ 12.5% sludge compared to plants grown with no sludge
(32.59 ± 0.7). ICP-OES analysis showed variations in mineral
element contents (macro and micronutrients) in coriander plant
grown I soil amended with sludge and compost.
