Abstract

Acidity is still a serious obstacle for maize cultivation due to the very low availability of phosphorus. The use of phosphate biofertilizers, containing phosphate solubilizing bacteria as an active ingredient, together with organic ameliorants was expected to be able to provide phosphorus for plants and increase the organic C content in the soil. Experiment aimed to find the proper application of phosphate biofertilizers along with organic ameliorants to support the productivity of maize on acid soils. A factorial randomized block design was used with phosphate biofertilizers and organic ameliorants as the first factor and doses of inorganic P fertilizer as the second factor, all treatments was equipped with three replications. Results showed that the application of phosphate biofertilizers consisted of Enterobacter ludwigii, Bulkholderia vietnamiensis, and Citrobacter amalonaticus with the composition of chicken manure compost (25%): municipal waste compost (25%): coconut shell biochar (50%) at a dose of 5 tons/ha was able to increase plant dry weight and dry weight of shells per hectare by 248.87 g and 12.960 kg. The application of phosphate biofertilizers and organic ameliorants showed no significant effect to soil C-organic content. Phosphate biofertilizers and organic ameliorants can support the productivity of maize plants on acid soils

Abstract

Soil salinity is still an obstacle that needs to be managed well on agricultural land located close to shoreline. The purpose of this study was to formulate an organic ameliorant to reduce soil salinity levels and increase the growth of rice plants on saline soils. The study was conducted in Jayamukti Village, Banyusari District, Karawang Regency from March to June 2022. Experiment used factorial randomized block design consisted of two factors with three replications. The first factor was the composition of organic ameliorant consisted of straw compost, husk charcoal, coconut shell biochar, dolomite, and humic acid. The second factor was the dose of organic ameliorant consisted of 0, 1, 2, and 3 tons/ha. The results showed that the application of organic ameliorant formulas in the form of 100% straw compost and 70% straw compost + 20% biochar + 10% dolomite at a dose of 3 tons / ha tended to be able to inhibit the decrease in saline soil acidity (0.15%) and reduce soil salinity levels (3.57%). The composition and dose of organic ameliorant interacted with each other in increasing the growth of rice plants by increasing plant height (40.10 cm) and number of tillers (6.00) compared to plants that were not given organic ameliorant on saline soil. Further research is needed on the efficacy test of the ameliorant formula in the field in increasing the growth and productivity of rice plants in saline land
