Landfill leachates, which are potential pollutants, may also carry significant amounts of nutrients that can be recycled by plants. We assessed the nutritional status and yield of wheat (Triticum aestivum L.) and properties of a Rhodic Kandiudult soil (depths of 0–10, 10–20, 20–40, and 40–60 cm) after 11 applications of landfill leachate over 4 yr. In the last application, wheat received 0, 32.7, 65.4, 98.1, or 130.8 m3 ha?1 (875 mg L?1 of nitrogen, N) of leachate and a positive control (90 kg ha?1 of N as urea) 15 d after sowing. Urea increased nitrate (>160 mg kg?1) in the topsoil (down to 40 cm), whereas landfill leachate increased nitrate (>60 mg kg?1) only at 40 to 60 cm with the highest dose, suggesting leaching. Urea-treated soil had less negative ?pH, which might have led to greater retention of nitrate in the topsoil. Sodium (0.02–0.26 cmolc Na kg?1), potassium (0.18–0.82 cmolc K kg?1), and electrical conductivity (0.05–0.14 dS m?1) all increased with leachate dosage. Treatments did not affect resistance to penetration and clay dispersion. Basal respiration increased with leachate dosage, whereas dehydrogenase activity decreased, suggesting effects on soil microbial metabolism. Microbial biomass and soil enzyme activities were not affected by addition of leachate. Nitrogen nutrition (15.1–22.7 g N kg?1 in flag leaves) and grain yield (1381–2378 kg grain ha?1) increased with leachate dosage so that the highest dose gave results similar to those for urea-treated plants (2563 kg grain ha?1). Landfill leachate showed strong potential as source of N for wheat but caused none, or transient, effects on soil properties. However, nitrate from leachate was more leachable than nitrate from urea.
