Popis: Several standard techniques currently used in the reclamation and revegetation of former quarry land in Italy's northern Apennine region were compared. The trial site, a 40-degree slope with clay soil, high pH and a little organic matter, was arranged in a randomized block design. The techniques assayed were hydro-seeding+tillage, hydro-seeding on sod, straw mulch+tar, jute mats+tillage+hydro-seeding, jute mats+tillage and a control. Each plot was enriched with equal amounts of chopped straw (120 g m−2), worm compost (140 g m−2) and the fertilizer Biosol® (140 g m−2); the binder Terravest® (36 g m−2) was also used in the three hydro-seeded plots. Ground cover, species, runoff and erosion were compared in each treatment. The overall 3-year data indicate significant differences in the treatments tested. There is a clear distinction between the treatments that promoted good grass cover growth and checked erosion (straw and tar, jute on tilled soil, and hydro-seeding on jute and tilled soil) on the one hand and the hydro-seeded treatments (on sod and on tilled soil), which showed no differences from control, on the other. © 1997 John Wiley & Sons, Ltd.
