Abstract

This research to determine the effect of azolla-based organic fertilizers, rock phosphate, and rice husk ash, and the best combination treatment to peanut yield on Alfisols. The experiment was conducted in April-November 2013 at the paddy fields of farmers in Sukosari village, Jumantono, Karanganyar District and in Laboratory of Soil Chemistry and Fertility and Soil Biology and Biotechnology Laboratory, Department of Soil Science, Faculty of Agriculture UNS for soil chemical and biological properties respectively. This experimental design used was Randomized Block Completely Design (RCBD) with 5 treatments and each repeated 5 times. Statistical analysis of the data using the F test at 5% level of confidence followed by DMRT if any signicant influence. The variabels observed were soil organic matter content, soil pH, total number of soil bacteria, plant height, number of root nodules, and seed weight. The results showed that there was significant differences among the treatments. The treatment of P1 (5 tons/ha azolla compost, 100 kg/ha phosphate rock and 75 kg/ha rice husk ash) provide the highest of soil organic matter content (4.31%) while P2 (5 tons/ha azolla compost, 50 kg/ha phosphate rock and 37.5 kg/ha rice husk ash) provide the highest dry seed yield (1011.09 kg/ha) which was 11.06 % higher than control treatment (910.38 kg/ha).

Abstract

Farmers began to implement organic systems when the quality of rice fields decreased. Indonesia has several active volcanoes so that the agricultural land was formed by generally Entisols. Several natural and synthetic soil conditioners were starting to be used to decompose the litter and increase the availability of Entisol nutrients. The research aimed to study the effect of providing biological soil amendments on the chemical properties of Entisols. The demonstration plots scale research were used a completely randomized design with a combination of treatments: (P1) Flooded dolomite control, (P2) Non-flooded dolomite control, (P3) Flooded bio soil-neutralizer, and (P4) Non-flooded bio soil-neutralizer. Parameters of soil chemical properties observed were pH, C-organic (%), N-total (%), P2O5-total (%), K2O-total (%), CEC (c mol + kg-1), total bacteria (CFU mL-1), and total fungi (spores g-1). The chemical properties of Entisols before treatment showed slightly acidic pH, low C-organic, low N-total, low K-total, low P-total, and very high CEC. After applying the soil neutralizer, there were an increase in chemical properties including pH becoming alkaline and neutral, medium C-organic, standards to moderat NPK-total, and high CEC. Flooding treatment did not increase the chemical properties of the Entisols.
