Abstract

The purpose of this research was to analyze the effect of mycorrhiza based biofertilizer on the availability of P on acid soils and pineapple plant growth. The research was conducted in green hause owned by PT. Great Giant Pineapple, Central Lampung District. The treatments were four doses of Rhizagold biological fertilizer (10, 30, 50, and 70 g / seeds), and 1 control (without Rhizagold biological fertilizer). Five treatments were arranged in a completely randomized design with three replications. Observations were done destructively five times to produce 75 units of experiments. The results showed that the application of mycorrhizal based biochemical fertilizers did not give significant effect on all pineapple plant growth parameters and did not give significant effect on soil pH parameter, P-total, only gave significant effect on P-available. A dose of 30 g seedlings-1 showed the best dose to increase P availability on soil.

Abstract

Nitrogen is a macro nutrient need by plants to enhance growth and productivity. Nitrogen element can be supplied through inorganic fertilizer, compost or biological fertilizer. The purpose of this study was to analyze the effect of vinasse compost and endophyte bacteria of Klebsiella sp. on nitrogen uptake and sugarcane growth. The treatments tested in this study were K0 = control (no compost vinasse and Klebsiella sp.), P1 = (Klebsiella sp. + 75% ZA + 25% vinasse compost), P2 (Klebsiella sp. + 50% ZA + 50% vinasse compost), P3 (Klebsiella sp. + 100% ZA fertilizer + 0% vinasse compost), P4 (without inoculation of Klebsiella sp. + 75% ZA + 25% vinasse compost), P5 (without inoculation of Klebsiella sp. + 50% ZA + 50% Vinasse compost). The treatments were arranged in a completely randomized design with five replicates. The results showed that endophyte bacteria could only enter in P1 treatment. The total N-content, N-available and N-absorption were associated with P1 treatment. Vegetative growth of sugarcane did not show significant different. The P1 treatment had the highest value of plant height and number of leaves. As for the number of tillers, on 4 terms, the highest value was observed on P2 treatment.

Abstract

The purpose of this study was to elucidate the effect of composting on changes in soil physical properties and to examine the relationship of soil physics properties with plant growth. The method used is a completely randomized block design implemented on the moor land located in the Village Lojejer Wuluhan District, East Java Jember. The study was conducted on 750 m2 of land with an altitude of 14 above sea level. Type of soil that is found in the research field is an Inceptisol having organic material content of 1.1%. Parameters measured aggregate stability, soil pore, bulk density, organic hatter, plant height, leaf number, wet weight of plant, and dry weight of plant. The results showed that addition of several doses of compost improved physical properties of the soil studied. The addition of compost increased the amount of microbes in the soil that played as soil adhesive agents that make the stabile soil aggregate. The soil aggregates stability could increase pores and decrease the weight of the soil content. Composting did not affect the growth of plants because at the time of vegetative growth compost did significantly effect soil physical characteristics.

Abstract

Nitrogen (N) is very important element for the vegetative growth of sugarcane plants. Character N is easy to change shape and become unavailable. This research was aimed reduce the use of inorganic fertilizer, reduce the loss of N and increase N levels with utilizing gliricidia leaves and utilization endophytic diazotrophic bacteria or  fixes nitrogen bacteria. The research used a completely randomized design with six treatments, i.e.  B0i0: control (0% + 100% ZA + no added bacteria inoculation), B0i1: (0% + 100% ZA + added bacteria inoculation), B1i0 (25% + 75% ZA + no added bacteria inoculation), B1i1 (25% + 75% ZA + added bacteria inoculation), B2i0 (50% + 50% ZA + no added bacteria inoculation), B2i1 (50% + 50%  ZA + added bacteria inoculation) with 5 replication. Variable observations included test of bacterial compatibility, soil total N, NH4+, NO3-, N uptake on leves, plant height, number of leaves and number of tillers. The research results showed that bacteria applied successfully entered the leaf tissue. The treatments were not significant for soil total N, NH4+, N03-, N uptake and number of tillers but significant for plant height at 6 week after planting and number of leaves at 8 and 12 weeks after planting. The organic matter of gamal leaf and bacteria endophytic diazotrophic were able to substitute ZA (ammoniu sulphate) inorganic fertilizer on sugarcane crop at 12 weeks after planting.

Abstract

Soil damage by biomass production is a change in the basic properties of the soil in the area of biomass production caused by human actions. This study aims to analyze the damage to soil biomass production based on the biological characteristics of six sub-districts consisting of 12 villages in Probolinggo. The methods used are quantitative and qualitative methods, which include taking soil and plant samples, testing, surveis, interviews, and FGD (Focus Group Discussion). The results of the FGD data are used to determine stakeholder perceptions regarding information on soil properties. The results of the survei at the sampling location showed that the soil texture was moderate, the structure was hard, and the soil thickness was around 50-150 cm. Two villages had a low category bacterial population ranging from 5.5×105–7.3×105 cfu/gram and 5 villages had a very low category bacterial population ranging from 9.55×104–2.45×106 cfu/ grams. Mushroom populations from 7 villages have a very low category of 6.15×104–2.75×105 cfu/gram and 5 villages have a low category. Bacterial and fungal populations in 12 villages showed that soil damage had not occurred, indicating that the abundance of bacteria and fungi was above the critical threshold (<102 cfu/gram). The results of stakeholder perceptions show ignorance that soil biological properties are an indicator of soil damage and ignorance that the continuous use of chemical fertilizers can kill bacteria and fungi.

Abstract

Mount Semeru eruption in 2020 and 2021 damaged 851 ha of productive land. Restoration of the affected lands requires information such as wide area, distribution, and eruption material characteristics. This community service aimed to provide a database as an overview of pyroclastic materials characteristics and elucidate potential-and-adaptive plants and microbes on post-Mt. Semeru eruptions. The volcanic ash contains significant elements (Al, Si, K, Ca, Ti, and Fe) and minor elements (V, Cr, Mn, Cu, Zn, Sr, Ba, Eu, and Re). Some of the plants that have survived post-eruption are annual shrubs and herbaceous plants such as grasses, so these plants can be used to restore the affected lands fertility after the Mt Semeru eruption. Based on economic evaluation and conditions in the field, the recommended adaptive plants are Pennisetum puparium and Musa paradisiaca. Both plants provide economic benefits for animal feed and farmers' income during post-eruption land recovery.

Abstract

Introduction: This study focuses on the effect of applying clay and compost on improving the quality of sandy soil in terms of the physical and chemical quality of the soil so that it can be a solution to problems in managing sandy soil so that the land can be productive and sustainable. Methods: This study used a factorial completely randomized design (RAL-F) with 3 treatment factors, namely: Depth (K1: 0-30 cm, K2: 30-60 cm), Dosage of compost (M1: 0 ton ha-1 as control, M2: 20 ton ha-1), Percentage of mineral soil (T1: 0% as control, T2: 25%, T3: 50%). Each treatment was repeated 4 times to obtain 48 pot units for the experiment. Data collection is carried out every 2 weeks for soil pH data. As for the other observation parameters taken in the last week of the incubation process, the data taken are chemical data in accordance with predetermined observation parameters which include soil physical properties such as bulk density, specific gravity, porosity, moisture content, pF value and basic chemical properties such as pH, organic matter, P-Available, N-Total. Results: Based on the results of laboratory analysis, it was shown that there was an increase in the average value of pH H2O and pH KCl every week, where initially the pH of H2O was 5.3 (1 MSI) to 5.9 (11 MSI) and the pH of KCl was from 5.1 (1 MSI) to 5.5 (11 MSI). This proves that the addition of organic matter and clay to the soil can increase the soil pH value. In addition to an increase in soil pH, there was also an increase in other chemical properties (BO, total-N and available-P) as well as soil physical properties (BI, BJ, Porosity and pF 2.5). Conclusion: the addition of clay soil and compost can improve the quality of sandy soil, especially the soil chemistry characteristics.
