A ground anchor for securing one end of a string or twine in the ground, so as to provide structural support via the string or twine when other portion of string or twine extends to and is secured at another point above ground. The ground anchor can be used for agricultural applications, relating to structural configurations in which vertical support is warranted for plants during their growth, such as for hop plants. The ground anchor can be formed of biodegradable material to break down following a period of time after the anchor is implanted in the ground. The biodegradable material can involve or include a nutrient resin which releases into the ground for soil nourishment following a period of time after the anchor is implanted in the ground.
