Sorshe Khol, also known as mustard cake or mustard seed residue, is a natural byproduct obtained after extracting oil from mustard seeds. It is widely used in organic farming and home gardening as a rich source of nutrients for plants. This residue is packed with essential elements such as nitrogen, phosphorus, and potassium, which are vital for plant growth and soil fertility. It not only acts as a fertilizer but also functions as a natural pesticide due to the presence of glucosinolates, compounds that help repel harmful soil pests and insects.

In traditional gardening practices, Sorshe Khol is soaked in water and left to ferment for a few days before being applied to the soil. This process helps release the nutrients in a more available form for the plants. When used regularly, it enhances soil structure, increases microbial activity, and supports healthy plant development, particularly in flowering and fruit-bearing plants.

Sorshe Khol is also known to improve the taste and quality of fruits and vegetables grown with its help. It is biodegradable, environmentally friendly, and safe to use around pets and children, making it a preferred choice for sustainable gardening. Its natural composition supports long-term soil health while reducing the need for chemical fertilizers or synthetic additives.
