Abstract
Acidic soils are marginal soils with low pH, dominated by Al and Fe ions which can bind essential nutrients such as P. Dissolving P and K from sources in the soil can be accelerated by microbial activity and ameliorant materials, also to improve nutrient availability and other soil properties. This study aimed to determine the effect of inoculation growth promoting bacteria and ameliorants to improve the chemical properties of acid soils and rice nutrient uptake of P and K. The research was conducted in greenhouse of Agriculture Faculty, Universitas Jember, from November 2021 – April 2022. It used a completely randomized design with two factors and three replications: ameliorant materials namely organic matter (A1), gypsum (A2), dolomite (A3), and NPK fertilizer (A4). The second factor was the inoculation of growth-promoting bacteria, namely without inoculation of bacteria (P0), phosphate solubilizing bacteria (PSB) (P1), potassium solubilizing bacteria (KSB) (P2), and a combination of PSB and KSB (P3). The bacterial species used were Bacillus valezensis and Bacillus sp.. The rice variety used was the local Pendok rice variety. The results showed no interaction between the application of growth-promoting bacteria and ameliorant. Ameliorant factor affected the increase in soil pH, the P concentration, and the uptake on the shoot of rice plants. The treatment of organic matter ameliorant and gypsum increased the phosphorus content of the plant canopy tissue by 0.420% to 0.426%. The P uptake of the rice plant shoot was increased by up to 27.59% with the addition of gypsum compared to the addition of NPK fertilizer.ABSTRAKTanah masam merupakan tanah marjinal dengan pH yang rendah, didominasi ion Al dan Fe yang dapat mengikat unsur hara esensial seperti P.

酸性土壤是一种pH值较低的边缘土壤,以Al和Fe离子为主,可以结合磷等必需营养物质。微生物活性和改良物质可以加速土壤中磷和钾的溶解,也可以改善养分有效性和其他土壤性质。本研究旨在确定接种促生菌和改良剂对改善酸性土壤化学性质和水稻对磷、钾养分吸收的影响。研究于2021年11月至2022年4月在荷兰Jember大学农学院温室进行。采用2因素3个重复的完全随机设计,改良材料为有机质(A1)、石膏(A2)、白云石(A3)和氮磷钾肥(A4)。第二个因素是接种促生长菌,即不接种促生长菌(P0)、增磷菌(PSB) (P1)、增钾菌(KSB) (P2)、PSB和KSB联合接种(P3)。细菌种类为芽孢杆菌和芽孢杆菌。使用的水稻品种是当地的Pendok水稻品种。结果表明,促生菌与改良剂的应用无交互作用。改良因子影响了土壤pH、磷浓度的增加和水稻植株对磷的吸收。有机质改进剂和石膏处理使植物冠层组织磷含量提高了0.420% ~ 0.426%。施石膏比施氮磷钾提高了水稻植株茎部磷吸收量27.59%。摘要/ abstract摘要:tanah masam merupakan tanah edge dengan pH yang rendah, didominasi Al dan Fe yang dapat mengikat unsur hara基本分离P.
