Abstract

Several particular plants are suggested to extract significant parts of heavy metals from soils and accumulate them in their roots and shoots.  This research aimed to study the phytoextraction of Cu by several plants from heavy-metal contaminated tropical soils.  Soil samples collected from plots treated in 1998 with 0, 15 and 60 Mg industrial waste ha-1 were planted with three different plants, i.e., caisim, water spinach, and lettuce.   Plant parts (roots and shoots) and soil samples were harvested after a four-week growth period and analyzed for plant and soil Cu.  The results show that the growth of plants was depressed by the increase in the soil Cu (extracted by 1 N HNO3) as affected by waste levels, with water spinach being the most progressive and produced the most significant biomass.  The absorption of Cu by caisim and water spinach increased with the soil extracted Cu (linear R2 = 0.71* for caisim and 0.32* for water spinach) and accumulated greater in plant roots than that in shoots. The translocation factor (TF << 1.00) indicates that all plants were good Cu phytostabilizators rather than phytoextractors, with water spinach being the best Cu extractor.

Abstract

Ultisol soil has a low organic matter content, CEC, and pH, causing an insufficient buffering capacity for N nutrients, especially NH4+. The objective of this study was to determine the effect of tillage and fertilization on the quantity and intensity (Q/I) of Ammonium (CRNH40, PBCNH4+, NH40, KG) in the soil, plant N and C uptake, and mung bean yields at the sixth growing season in ultisols. This study was arranged in a 2 × 2 factorial in a Randomized Block Design (RBD). The first factor was the tillage system (T), namely minimum tillage (T0) and intensive tillage (T1). The second factor was the fertilization (P), namely without fertilizer application (P0), and with fertilizer application (NPK 200 kg ha-1 + 1 Mg ha-1 chicken manure) (P1). Each treatment was replicated four times. The results showed that the application of NPK fertilizer significantly affected the mung bean yield, mung bean plant Nitrogen and Carbon uptake at harvest time. While, the intensive tillage had a very significant effect on increasing the N uptake compared to the minimum tillage. Minimum tillage and fertilization increased Q/I parameters (PBCNH4+, KG, CRNH40, and NH40). The parameter of Q/I (CRNH40) was significantly correlated with mung bean plant N and C uptake. PBCNH4+ and KG were significantly correlated with mung bean yields.
