N2 - Humic acid can neutralize soil pH, adsorb plant nutrients and clay as well as balance cations, thereby increasing the stability of soil aggregates, plant uptake and yield. Sources and doses of humic acid have been estimated for the efficiency of cation absorption. This experiment aimed to examine the effectiveness of various organic matter sources and humic acid doses on nutrients availability. We prepared greenhouse experiments according to factorial random block design (RBD). The first factor was three organic matters: compost, manure and coal, and the second factor was six doses of humic acid: 0, 0.5, 1.0, 1.5, 2.0 and 2.5 g/kg. We evaluated the effectiveness of humic acid to change soil salinity, pH, electric conductivity, cation exchange, permeability, aggregate stability and plant growth. The experimental results showed that humic acid from peat increased plant biomass weight, plant roots, grain number of tillers and chlorophyll content more than others. Humic acid efficiently can improve rice yields 10-20% supported by the suitability of soil pH, nutrient availability and soil salinity.
