IMPACT OF AGRICULTURAL PRACTICES ON NITRATE LEACHING FROM THE ROOT ZONE

Objective

THE AIM OF THE PROPOSED RESEARCH IS TO DEVELOP QUANTITATIVE METHODS FOR SIMULATING THE IMPACT OF AGRICULTURAL MANAGEMENT AND ENVIRONMENTAL PROTECTION STRATEGIES ON NITRATE LEACHING FROM AGRICULTURAL SOILS AND FOR OPTIMIZING N-FLUXES IN SOIL.

THE PROJECT WILL FICUS ON:

1.- IMPROVEMENT, TESTING AND CLASSIFICATION OF NITRATE LEACHING MODELS WITH A VARYING DEGREE OF DETAIL.

2.- COLLECTION OF UNIFORM DATA ON EXPERIMENTAL FARMLAND WITH DIFFERENT CROPS, MANAGEMENT, SOIL TYPES AND WEATHER TPES REPRESENTING MAJOR AGRICULTURAL AND ENVIRONMENTAL CONDITIONS IN THE PARTICIPATING COUNTRIES.

3.- EXTRAPOLATION OF POINT DATA TO AREAL DATA USING SOIL (SURVEY) DATA, TRANSFER FUNCTIONS AND GEOSTATISTICAL SAMPLING AND INTERPOLATION TECHNIQUES.

4.- APPLICATION OF THE MODELS AND COMPARISON OF RESULTS ON FIELD AND-OR REGIONAL SCALES FOR DIFFERENT MANAGEMENT SYSTEMS AND ENVIRONMENTAL POLICIES.

5.- EVALUATION OF MANAGEMENT PRACTICES AND PROTECTION STRATEGIES THAT OPTIMIZED FLUXES OF N IN SOIL AND REDUCE LEACHING TO THE GROUNDWATER.

THE PROJECT IS INNOVATIVE BECAUSE THE
I - MODELS AND TECHNIQUES DEVELOPED ARE NEW AND POWERFUL TOOLS FOR DRAFTING AND SUPPORTING MEASURES TO REDUCE NITRATE POLLUTION OF GROUNDWATER AND
II - DATA COLLECTION AND MODEL TESTING COVERS A WIDE RANGE OF AGRICULTURE AND ENVIRONMENTAL CONDITIONS AS PRESENT IN THE
