Potassium thiosulfate is commonly used as a fertilizer to provide sulfur and potassium to crops, two essential macronutrients for plant growth. Potassium is important for root development and overall plant health, while sulfur is necessary for the formation of certain amino acids and proteins. When applied to crops, potassium thiosulfate can help to improve plant growth, increase yield, and enhance the quality of the harvested produce. Potassium thiosulfate is often applied to crops as a foliar spray or as a soil amendment. As a foliar spray, it is applied directly to the leaves of the plant and absorbed through the leaf tissue. As a soil amendment, it is applied to the soil and taken up by the plant roots.

In California, potassium thiosulfate is commonly used as a fertilizer to increase crop yield in a variety of agricultural applications. One common use of potassium thiosulfate in California is in the production of high-value nuts, such as almonds, walnuts, and pistachios.
