Geostatistics in Precision Agriculture

• David Mulla was the first person to apply geostatistics explicitly in precision agriculture
• David Mulla aimed to study: i) Introduce geostatistics for mapping patterns in soil Pand K, (ii) determine the nature and extent of spatial variation in these crop nutrients in a large irrigation circle and (iii) determine what sampling intensity is necessary toidentify the major patterns in the soil.
• Mulla and Hammond stated that the variable-rate programme needed appropriate sampling and an accurate map of the crop nutrients.
• Mulla and Hammond’s recommendations were that if the soil is variable farmers should avoid uniform applications.
