New soil sampling method for increased volume of soil sample

Conventional soil sampling usually considers sample weight of 2 kg per 4-5 ha area, which means that representative sample in relation to soil mass up to 30 cm depth is presented through the ratio 1:10000000. New sampling method changes the ratio to 1:625000, thus increasing amount of sampled soil 16 times with assumption that such sample better describes investigated area. Moreover, new soil sampling probe can be used for precision farming purposes where the central point of the probe ring is positioned with precision of ±1 cm and represented with 4, 8 or 16 samples taken in 50 cm radius from the center. Soil probe prototype was tested in different soil types and in different parts of Croatia. Using new soil sampling method for soil survey and applied geostatistical tools provides a solution for quantifying spatial variability of soil properties, possibilities for commercial activities and a way to introduce variable rate technology in agricultural input application which can optimize farm profitability through improving yield, reducing input costs and minimizing input losses to the environment. It could be very useful for soil sampling on contaminated sites and for Nitrate Directive purposes. The objective of sampling should be to provide information helpful to management decisions, and to fill knowledge gaps. Sampling should supplement a dynamic spatial information system that stores all relevant data collected within each farm field. Efficient sampling needs to be based on all information sources available to the land manager, and is an iterative process resulting in increasing understanding and improved management over time. The probe prototype was tested in different soil types and in different parts of Croatia. In the paper the results of basic soil chemical parameters are presented for 3 experimental locations.
