- Abstract
- The agricultural management techniques and mechanization adopted
in sloping areas under temperate and sub-continental climate can
affect the physical and hydrological characteristics of the soil with an
increase of the soil erosion rates. Vineyards have been reported
among the land uses most prone to erosion. Agricultural operations
can be conducted to enhance the soil conservation, it is therefore
important to know the site-specific characteristics and conditions of
adopted practices. A long-term monitoring to evaluate the influence of
management systems in hilly vineyard on erosion and runoff and soil
properties has been carried out in the north-western Italy since 2000 properties has been carried out in the north-western Italy since 2000.
Three different inter-rows tillage systems were compared:
conventional tillage (CT), reduced tillage (RT) and controlled grass
cover (GC). To record the rainfall amount and duration, an agrometeorological
station was located near experimental plots. The three
plots are hydraulically isolated, thus runoff and sediment have been
collected at the bottom by a drain, connected with a tipping bucket
device to measure the discharge of runoff. The system was
implemented with electromagnetic counters that allow the automatic
accounting with data capture by a control unit, powered by a
photovoltaic panel and transmitted to a data collection center for
remote viewing via web page. A portion of the runoff-sediment mixture
was usually sampled and analyzed for soil and nutrients losses. In
order to analyze with more detail the erosion process by means of
predictive models, a micro-plot system was placed in the experimental
site in 2012. Splash cups have been installed in each plot since 2011
to evaluate how the soil management affects the in-field splash
erosion process. Rapid measurement of soil moisture content and
temperature were performed starting from August 2011 to allow
continuous monitoring of parameters that can provide an evaluation of
space-time hydrological processes, determining the surface runoff
response to a given precipitation events. Electromagnetic sensors
were installed in the topsoil and measures were recorded in one-hour
intervals by a data collection device. Some physical and hydrological
properties were considered to provide information on the degree of
soil compaction and its influence on soil status. The parameters
analyzed are bulk density by core method and soil compaction by
static and dynamic recording penetrometers. Since autumn 2011 the
reduced tillage management was replaced with conventional tillage
with a grass strip in the bottom of each inter-row (CTS). At the same
time the grass cover of the GC plot was renewed after execution of
tillage operation. Recurring measurements of the soil water content up
to a depth of 60 cm and hydraulic conductivity tests with the Simplified
Falling Head Technique (SFH) have been started in 2012, to observe
the spatial and temporal variability of hydraulic behavior in the
experimental plots. (literal)
