		abstract={The effect of application of cattle dung in the form of compost and biochar on P available and P uptake of corn plants on Ultisol was carried out to determine the comparison of the two types of treatment forms. The study used a nonfactorial randomized block design with dosage levels of cattle dung compost material and cattle dung biochar (5, 10, 15 tons / ha). The parameters measured are pH H2O, pH KCl, P available, organic C, total P, Al-dd, plant height, shoot dry weight, root dry weight and P uptake of plants.
The results showed that cattle dung compost and cattle dung biochar were able to increase the pH of H2O, pH of KCl, P available, P total, organic C, plant height, shoot dry weight, root dry weight and P uptake of plants and were able to reduce Al-dd. Cattle dung biochar is better in increasing available P, H2O pH, KCl pH, and total P of Ultisol than cattle dung compost.}
