A soil sampler includes a base and a plunger insertable into the base. The depth in which the plunger is inserted into the base determines the size of the sample collected by the soil sampler. The depth in which the plunger is inserted into the base can switch between a first size and a second size, allowing the user to collect different sample sizes using a single soil sampler. The soil sample that is collected can then be ejected from the soil sampler by shifting the plunger to an eject position relative to the base in which the plunger can shift further into the base to eject the soil sample.
