Platform field's experiments are focused on establishing the effect on yields and soil of the application of two tillage systems, two increasing fertilizer rates and variants of integrated weed control over three field crop rotation of the type (wheat/triticale - maize - triticale/wheat). The experiments also aim to investigate the vulnerability to drought using the soil water balance simulation models for determining the “plant-soil-atmosphere” interactions as long-term crop evapotranspiration, net irrigation requirements, irrigation scheduling and risk of drought.
