Soil enzyme activities (actual and potential dehydrogenase, catalase, acid and alkaline phosphatase) were determined in the 0-20-, 20-40- and 40-60-cm layers of a brown luvic soil submitted to a complex tillage (no-till and conventional tillag... see more

We have determined five enzymatic activities (actual and potential dehydrogenase, catalase, acid and alkaline phosphatase) and one nonenzymatic catalytic activity (H2O2 splitting in autoclaved samples) in the 010, 1020 and 2030cm layers of a brown luvic s... see more

The paper based on the researches carried out during 2005 – 2008 in the long term trial placed in 1990 on the preluvosoil from Oradea. The monoculture of maize, maize – wheat and maize – soybean – wheat crop rotations were studied in unirrigated and irrig... see more

We have determined five enzymatic activities (actual and potential dehydrogenase, catalase, acid and alkaline phosphatase) and one nonenzymatic catalytic activity (H2O2 splitting in autoclaved samples) in the 0–10–, 10–20– and 20–30–cm layers of a brown l... see more

The paper is based on the research results obtained during 2001-2005 in Oradea in the long term trial placed on preluvosoil in 1976.During the vegetation period of the potato, the following quantity of the rainfall were registered: 426.2 mm in 2001, 210.4... see more

The paper presents the results carried out in Oradea on the hill with slope of 8% in the plot for determination of the soil and water flow. The variants studied were: clean fallow grassland, wheat, maize seeded on the direction of the level curves and mai... see more
