Soil management techniques can definitely influence soil quality, and particularly soil organic matter content, biological complexity, structure, and water holding capacity. Tillage may also have a negative effect by increasing erosion and organic matter oxidation processes, which have unavoidable repercussions on fertility. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2016) 40: 194-202 © TÜBİTAK doi: Research Article Impact of long term soil management practices on the fertility and weed flora of an almond orchard 1, 1 2 2 3 Giovanna CUCCI *, Giovanni LACOLLA , Carmine CRECCHIO , Silvia PASCAZIO , Donato DE GIORGIO 1 Department of Agricultural and Environmental Science, University of Bari ‘Aldo Moro’, Bari, Italy 2 Department of Soil, Plant, and Food Science, University of Bari ‘Aldo Moro’, Bari, Italy 3 Agricultural Research Council, Bari, Italy Received: Accepted/Published Online: Final Version: Abstract: Soil management techniques can definitely influence soil quality, and particularly soil organic matter content, biological complexity, structure, and water holding capacity. Tillage may also have a negative effect by increasing erosion and organic matter oxidation processes, which have unavoidable repercussions on fertility. The objective of the current research was to test the effects of five different management techniques applied for 35 years on a rain-fed almond grove (Prunus amygdalus Batsch) in a hot-dry environment on some physicochemical, hydrological, and biological parameters. The following soil management techniques were compared: no-till (NT), with weed control by preemergence herbicides; NT, with chemical weed control by foliar herbicides; NT, with weed control by mowing; tillage, with sowing and field bean green manuring; and conventional tillage. The current survey supplied interesting results, considering the typical soil and climate conditions of the tested area (southern Italy), characterized by high summer temperatures, low rainfall, clay loam soil, and an arable layer of m. The most influenced values are those concerning the organic matter due to the supply of biomass resulting from weed mowing or field bean green manuring. The NT .
