The source of phosphorus and potassium for plants, which commonly from inorganic fertilizer, can be replaced by other sources such as Guano and K 2 CO 3 . Guano is organic material rich in P and other soil nutrients, which has the function as well as rock phosphate. Furthermore, potassium carbonate (K 2 CO 3 ) has 56% of K, higher than KCl, which only has 52% so it has potential as a source of K for plants. This study aimed to find out the dose of Guano and K 2 CO 3 as an alternative of P and K fertilizer on soil potential-P, potential-K, and soil reaction (pH). The experiment was conducted at Situgede Garut – West Java with an altitude of 1,200 m above sea level with soil reaction 6.05. The experiment was conducted from April to July 2018. The method used was a Randomized Block Design with nine treatments and three replications. The experiment result showed the value of soil potential-P (P 2 O 5 HCl 25%) and potential-K (K 2 O HCl 25%) due to treatment of Guano and K 2 CO 3 statistically no difference to with treatment of NPK standard. Therefore, K 2 CO 3 and guano have potentially been used as a fertilizer compound.
