Maluku in general and Ambon municipality in particular is a region with the lowest peanut production as compared to its national production. Cambisol is one of soil type that has good soil physical properties, but it is low in N and P contents and has an acidic reaction that inhibit the growth of peanut plants.  The research was conducted in a plastic house in Halong Village, Teluk Ambon Baguala Subdistrict, from April to Juli 2012. This research used a Completely Randomized Design with two factors, i.e. factor 1 with three levels of dolomite fertilization, consisting of D0 (without dolomite), D1 (0.3g dolomite per pot), D2 (0.6 g dolomite per pot), and factor 2 with three levels of phosphate fertilization consisting of P0 (without phosphate fertilizer), P1 (0.7 g SP-36 per pot) and P2 (1.4 SP-36 per pot). The results showed that the application of SP-36 increased the number of root nodules and yield of peanut. Response was even better if accompanied by the application of dolomite. Leaf N uptake could be enhanced by application SP-36, but it was independ from the application of dolomite. The highest peanut yield of 41.83 g per pot was achieved with the fertilizer combination of D1P2  (0.3 g dolomite per pot and  1.4 g SP36 per pot)

AbstractThe passivation effects of blast furnace slag, fly ash, corncob biochar, and phosphate fertilizer in Pb-contaminated soil was evaluated against the soil pH, available Pb content, Pb fractions, and bioactivity coefficient. Blast furnace slag and fly ash could increase soil pH, while corncob biochar and phosphate fertilizers lowered soil pH. The available Pb content in the blast furnace slag and phosphate fertilizer treatment groups was significantly lower than in other treatments. Also, blast furnace slag and phosphate fertilizer could significantly convert nonresidual Pb into residual Pb. Combined with the environmental impact after application and cost of the material, it is recommended that blast furnace slag can be used as a passivation agent for low-concentration Pb-contaminated soil.

ABSTRACT: Interference between root systems occurs below the ground surface long before the competition between plants is expressed in the shoot. Nutrients stand out for being limited in the soil, requiring supplementation, especially phosphorus. Thus, this study aimed at estimating, from sowing, visual characteristics in the root systems of bean plants from the Carioca variety (Phaseolus vulgaris) when in competition with brachiaria (Urochloa brizantha), considering also the application of phosphorus P2O5. A factorial design with six treatments was used resulting from the combination of three cultivation schemes (beans in isolated crops or in competition with one or two brachiaria plants), and the application or not of phosphate fertilizer (90 kg ha-1 of P2O5), in a completely randomized design with four replications. After the sowing of the species, the visualization results were taken at every 12 hours, by means of the photographic record of the development of the root system in rhizotrons. Greater growth and greater total area of the root system were observed in bean monocultures and when competing with one brachiaria plant in the presence of phosphate fertilization. In contrast, the bean plant in the container with two brachiaria plants invested its resources in greater length and total area of the root system when in the absence of the fertilizer. It can be stated that there is evidence of interference starting three days after the sowing of the species.

The availability of phosphorus in the soil is a factor that directly interferes with its absorption by plants. This availability can be influenced by the texture, dose of the phosphate fertilizer and the time of contact with the soil. This study aimed to quantify the organic and inorganic fractions of P accumulated in a sandy soil receiving doses of phosphorus, incubated and grown with rice. The experimental design was a completely randomized design, in a 4 × 3 factorial scheme, with four replicates, and four P doses (0, 80, 240, and 410 mg dm-3) and three evaluation times (before sowing, after harvest, and incubated). Soil samples were collected before, after incubation, and after rice harvesting, and then submitted to a chemical fractionation of P. P fractions were influenced by soil collection times. The inorganic fractions prevailed before sowing and after incubation, and the organic fractions prevailed after harvest. Phosphate fertilization favored mineralization of organic P and redistributes the inorganic and organic P fractions, between labile and non-labile compartments. The application of phosphate fertilizer in an Entisol Quartzipsamment contributes to the accumulation of inorganic fractions, especially in the most labile fractions.

The low yield of rice in thick peat can be overcome by provisioning complete nutrients. Various efforts have been made to increase the productivity of Indonesian peatlands, one of which is by adding salted fish waste and cow manure. This research was carried out on a plastic house scale from October 2017 to January 15, 2018, in Pelalawan District, Pelalawan Regency, Riau. This research was arranged in a Completely Randomized Design (CRD), consisting of eight treatments, namely L0 = Control, L1 = 1.5 ton.ha-1 of fish waste, L2 = 2.25 ton.ha-1 of fish waste, L3 = 7 tons/ha of cow manure, L4 = 15 ton.ha-1 of cow manure, L5 = 1.5 ton.ha-1 of fish waste + 7 ton.ha-1 of cow manure, L6 = 1.5 ton.ha-1 of fish waste + 15 ton.ha-1 of cow manure, L7 = 2. 25 ton.ha-1 of fish waste + 7 ton.ha-1 of cow manure, and L8 = 2.25 ton.ha-1 of fish waste + 15 ton.ha-1 of cow manure. The results showed that the application of cow manure and salted fish waste could increase soil pH, total NPK, and NPK uptake. The application of 2.25 tons/ha of fish waste and 15 tons/ha of cow manure resulted the best results in soil pH, total NPK, and NPK uptake, therefore it is recommended for the cultivation of lowland rice on peat soil.

ABSTRACT The elemental sulfur (S0) application may reduce soil pH, benefiting plants adapted to acid conditions and lessening problems of overliming. Nevertheless, there is no official recommendation for its application. The objective of the study was to quantify the S0 doses required to reduce the pH of soils from Southern Brazil. The experiment was carried out in the laboratory in a factorial scheme (5 × 5), with a completely randomized design and three replicates. The treatments consisted of five soils, and five doses of S0, corresponding to 0, 50, 100, 150, and 200% of the estimated dose need to reach pH 4.0. The applied doses of S0 resulted in reduction of pH and base saturation (V%) and increase of potential acidity (H + Al). These effects, however, were reduced due to the low rate of oxidation of the S0 applied (0.76-3.36%). The soil variables correlated with S0 oxidation were Mg2+ (0.86***), Al3+ (-0.82***), H + Al (-0.89***), V% (0.68***) and aluminum saturation (m%) (-0.87***). In the evaluated soils the oxidation of 50 kg ha-1 of S0 was required to reduce one unit of pH in H2O.

Inceptisol is a young and newly developed soil so it needs to be optimized for crop cultivation. The aim of this research is to know the availability of soil P, P uptake and corn yield after application of granular composting of sago waste (KGES) together with phosphate fertilizer to Inceptisols soil. The experimental treatment was KGES which consisted of three levels: without KGES, 40 tons KGES ha-1, and 80 tons KGES ha-1, and the use of SP-36 (P) fertilizer consisting of three levels: without P fertilizer, 120 kg P ha-1, and 240 kg P ha-1. The experiment used a complete randomized design with 3 replications. The result of the experiment was analyzed variance and relationship test using interlaced analysis. The results showed that KGES together with phosphate fertilizers could increase soil pH causing phosphate to be available and plant roots could absorb nutrient phosphate well, so that the yield of corn kiln dry weight also increased. The highest yield of dry weight of grains (7.85 tons per ha) was obtained from a combination of 80 tons of KGES ha-1 and 240 kg P ha-1.Keyword: Keywords: Ella Sago, Inseptisols, maize, phosphate
