Abstract
This study aimed to determine the changes in some chemical properties of coastal soil and the growth of pakcoy (Brassica rapa L.) given chicken manure and to obtain a treatment that changed the chemical properties of coastal soil and the growth of pakcoy (Brassica rapa L.) was more good. This study used a randomized block design (RBD) consisting of 4 treatments, namely A0 (without chicken manure), A1 (100 g chicken manure polybag-1), A2 (200 g chicken manure polybag-1), and A3 (300 g chicken manure polybag-1). Soil analysis was carried out at the Nanotechnology Laboratory, Halu Oleo University. This study showed that chicken manure increased the nutrient content of total N-, P-available, C-organic, and pH in coastal soil, with a dose of organic fertilizer that gave the best effect, namely 100 g polybag-1.
