Abstract

Andisols are considered as productive soils, but their P-retention have to be reduced to increase the available P.  This research concerning the remediation of Andisols with steel slag and bokashi of husk to overcome the P problem and to investigate their  influence  to soil physical aspects.  The treatments were arranged in Randomized Block Designed in factorial pattern with two factors: steel slag and bokashi of husk, consisted of four level: 0, 2.5, 5.0 and 7.5 % of soil weight (w/w). The treatments were repeated twice, brought a combination of 4 x 4 x 2.  The soils with each treatments were mixed thoroughly, filled into the polybags, watered to the field capacity, closed tightly, incubated for four months, and sampled for chemical and physical analyses. The parameters were P-retention, bulk density, permeability and aggregate stability.  The result showed that steel slag and bokashi of  husk were interacted in decreasing P-retention.  These combination had no effect to soil physical characteristics which mean that the treatments did not aggravate the bulk density, soil permeability and aggregate stability. The remediation of Andisol with steel slag and bokashi of husk decreased the P-retention, and kept the good aspects of soil physical characteristics.

Abstract

Azotobacter chroococcum based biofertilizers have been widely used in the production of environmentally agriculture. For commercial scale, cheap growth media for Azotobcter inoculant  will affect the quality and price of liquid biofertilizer. Growth medium should support cell proliferation as well as its  nitrogen fixation and phytohormone production.  The objective of this study was to determine whether  liquid organic fertilizer (LOF) containing low N can be used as a medium for scaling up  A. chroococcum inoculant without lowering the survival of bacteria and its activity in N2 fixation and phytohormones production. LOF generally contains a complete nutrient although in a small quantities. Experiment was set up in completely randomized design which tested two types of commercial LOF. The results showed that both of  LOF were only able to support cell growth up to 72 hours and at 96 hours cell viability began to decline compared to the control medium,  free-N Ashby. At 72 hour total N and cytokinin  concentration in LOF was lower than those in Ashby media. This study revealed  that LOF  could be used as A. chroococcum growth media, but without optimization of its composition, cell density and cytokinin content would be lower than those of inoculant  in Ashby Media.

Abstract

Ultisol is low fertility soil and as low available P due to P fixation by Al and Fe. The phosphate solubilizing microbes (PSM) is the microbial group that enable realease fixed-P to soil solution and be absorbed by plant. This research was aimed to determine the effects of PSM biofertilizer and phosphate fertilizer dosage combination on soil potential P, total phosphate solubilizing bacteria (PSB) population and yield of maize (Zea mays L.) grown in Ultisols. This research used a Randomized Block Design that consist of nine treatments with three replications. The treatments were 100 kg ha-1 of SP-36 fertilizer, 50 kg ha-1 of PSM biofertilizer, SP-36 fertilizer (50 kg ha-1 and 100 kg ha-1) with PSM biofertilizer (25 kg ha-1, 50 kg ha-1 and 75 kg ha-1) repectively. The result showed that the combination of PSM and phosphate fertilizer dosage had significantly effect on PSB total population and maize yield, but did not not on  potential P. This experiment suggested that SP-36 fertilizer with 50 kg ha-1 dosage and PSM biofertilizer with 50 kg ha-1 dosage is the best combination.

Abstract

Heavy metal contamination in paddy field which came from industry nearby and agricultural input. Increased level of toxic heavy metal cadmium will threat rice production and quality. Bioremediation by used of rhizosphere bacteria is an easy, cheap and effective method to control toxic metal uptake. Pot experiment has been done to study the change in cadmium uptake after biofertilizer Azotobacter chroococcum inoculation and some soil ameliorant. Expirement has been carried out in factorial completely randomized block design with A. chroococcum and ameliorant as treatments.   Either Azotobacter inoculation or soil ameliorant didn’t change soil acidity, the soil still neutral. Rhizosphere of paddy received biochar, hay compost and biochar and inoculated with 108 cfu mL-1 Azotobacter was colonized by more Azotobacter compared to uninoculated one. All plant treated with Azotobacter has higher nitrogen uptake but lower cadmium uptake. This experiment suggested that biofertilizer Azotobacter has a significant role to decrease cadmium uptake by padi, an important food crop.
