Kalium diperlukan tanaman dalam jumlah yang kecil digunakan sebagai katalisator terutama dalam pengubahan protein dan asam amino, namun kalium merupakan kadar terbesar yang terkandung dalam rumput laut. Kekurangan kalium dapat menyebabkan terhambatnya fotosintesis dan bertambahnya respirasi sehingga mengakibatkan pertumbuhan terhambat dan kerapuhan pada tumbuhan sehingga mudah patah dan rusak (Dwidjosaputro, 1992).
