P1.04-2 Soil core sampler: specific 04.04 Gouge auger set for stepwise sampling By first taking a sample with the gouge with the largest diameter and subsequently with gouges having smaller diameters cross- contamination among the samples is avoided. The set is very suitable for profile research (nitrate research) in soils with a somewhat higher penetration resistance. 04.03 Gouge auger model P This bi-partite gouge auger distinguishes itself from other gouges by the cylindrical tapered cutting  head at the bottom side of the gouge that, when the auger is pushed into the soil, cuts a cylinder  shaped piece from the soil. As a result the auger does not need to be revolved around its axis after  being inserted. This type of auger is particularly suitable for soil mapping because of its small diameter  and the cylindrical cutting head. 04.06 Gouge auger set for top layers After analysis of the samples taken with this set it is possible to determine a fertilization program. These gouge augers are pre-eminently suitable for sampling of the top layers of arable land, in particular for a nitrate- or a fertilization research, etc. 05.03 Grass plot sampler, small 05.10 Grass plot sampler, large These stainless steel gouge augers with different dimensions consist of a steel auger pipe, a collecting bucket and a stick with a steel handle. Because of the conical shape of this pipe the sample is easily pushed toward the collecting trough when the next sample is taken. The grass plot sampler is particularly suitable for research in grassland farming but also in horticulture and for the Parks and Public Gardens Department.
