摘要

Terrestrial flora refers to plants that grow on land rather than in water. Their rapid spread is disrupting agricultural soils, negatively impacting seed germination and plant growth. The current study examines the efficacy of terrestrial weeds compost (TWC) amendment on the engineering and ionic properties of the soil and morphological properties of Abelmoschus esculentus. The TWC (Ageratum conyzoides compost (ACC), Parthenium hysterophorus compost (PHC), and Lantana camara compost (LCC)) have significantly increased soil porosity at 120th day in 20% amendment by 10.56, 11.85, and 17.94%, respectively, compared to soil alone, and significantly increased soil water holding capacity (WHC) at 120th day in 20% amendment by 68.42, 61.24, and 72.7%, respectively, compared to soil alone. The TWC has substantially decreased heavy metal transport into the plant system, and fruits of A. esculentus grown in 20 to 25% amended composts had a 15 to 20% increase in nutrients compared to A. esculentus grown in soil alone. Use of composts reduced non-carcinogenic health concerns. The risks for Pb, Ni, and Zn in ACC, PHC, and LCC composts remained significant, when applied in higher amounts. The study can be applicable to remediate contaminated soils.
