Abstract
One of the problems facing in dry land area management is soil fertility. This research was aim to improve soil fertility and maize yields by applying Local Microorganisms (LoM) solution and lime. The research was carried out on dry land area in Mandalawangi Subdistrict, Pandeglang, and Cimarga Subdistrict, Lebak, Banten from June to December 2016. This field experiment was done using Randomized Block Design, where the treatments were three levels of fertilization packages, i.e. (1) 300 kg Urea + 150 kg SP36 + 100 kg KCl; (2) 300 kg Urea + 150 kg SP36 + 100 kg KCl + 1 ton manure + 1 ton lime; (3) 300 kg Urea + 150 kg SP36 + 100 kg KCl + 1 ton manure + Local Microorganism (LoM) solution. The research results show that applicaton of LoM solution and lime significantly improved soil biology. The application of lime and LoM solution increased soil respiration, where level of soil respiration was higher on the application LoM solution than lime. Application of LoM solutions significantly improved soil microbe activities, which in turn affected the maize growth and its yield. Application of LoM solution increased maize yield by 37.92%.
