can be supply by Guano fertilizers on post coal mining soil. The research is done
in a screen house at chemistry and fertility soil Faculty of Mulawarman University
Samarinda. The research was start on November until January 2007.
Completely Random Design (CRD) was used in this treatment researced
by 5 tratments with 5 time replications. Where is they are G0 without Guano, G1
= 25 g polybag

harvest, the soil was composited every replication and of every treatment was
analysed a couple of chemical characteristies. For data crop was by variance
analised and continue by BNT on 5% for treatmen showing significant. difference.

amount of element 28 days after planting and high wed plants.
