    Various methods of field data collection and spatial analysis Various methods of field data collection and spatial analysis Presentation Transcript

    • Various methods of field data collection and spatial analysis Alex Melnitchouck, Ph.D. IntelMax Corp. Calgary, AB, Canada www.Zoner.Ag
    • What do these fields have in common? The Netherlands Germany Alberta, Canada Indiana, USA Ukraine France www.Zoner.Ag
    • Is this field variable? www.Zoner.Ag
    • Is this field variable? (2) www.Zoner.Ag
    • Grid soil sampling Soil maps are used for calculation of fertilizer rates Yield goal is determined as an average for the whole field # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # www.Zoner.Ag
    • EC mapping …not necessarily “Veris” mapping; Method is based on the relationship between soil EC and concentration of anions and cations in soil as well as soil moisture. It is effective in the regions where high or low pH and salinity are main yield limiting factors. www.Zoner.Ag
    • Optical sensors Popular in the areas, where most of nitrogen is top-dressed (corn, winter wheat etc.); Can be used for top-dressing, targeted application of pesticides , soil mapping etc. www.Zoner.Ag
    • Yield data The concept is based on variability of yield potential across the field; Field is divided into several zones with various yield potential; For each zone, certain fertilizer rate is planned depending on soil fertility and yield goals www.Zoner.Ag
    • What is yield? • Varieties/Hybrids • Crop rotation • Tillage • Agronomy • Fertilizer • Crop protection • Machinery etc. • Soil OM • N, P, K, S • H2O • Ca • Mg • Micronutrients • pH • GDD • Slope • Wind speed & direction • PAR …>140 factors www.Zoner.Ag
