Abstract

The use of compound inorganic fertilizers in plant cultivation systems is on the rise because of their practicality, more comprehensive and homogeneous nutrient availability, and potential to reduce production costs. Different combinations of compound fertilizer products can generate a variety of responses in terms of plant growth. The aim of this investigation was to assess how plants responded to the components of their results, specifically the variations in two distinct compositions of compound fertilizers. This investigation divided 60 experimental sites into two groups, each using two distinct types of compound fertilizers. The macronutrient content of the compound fertilizers (NK and NP), distinguished them. This study employed nine treatments, which included a control (without fertilizer treatment), conventional NPK fertilizer, a combination of NPK fertilizers (3/4, and 1) doses with (1/2, 3/4, 1 and 1) doses of compound fertilizer, and a randomized block design Each treatment was repeated three times. The results of this study suggest that the application of compound fertilizer with two distinct compositions has a substantially different effect than the control treatment. In comparison to compound fertilizers with a higher potassium content, which have a yield component value of RAE 134%, the application of compound fertilizers with a higher phosphorus content can provide a higher yield component value of RAE 127.92%. The function of applying potassium-containing nutrients can produce better outcomes for corn plant than those with higher phosforus content, making it an interesting study that should be investigated further in the future

Abstract

Plant productivity is influenced by soil quality and availability of plant nutrients. Soil conditioner can improve soil quality by enhancing soil properties. Both macro and micronutrients can be fulfilled through application of nutrient solution containing macro and micronutrients and biofertilizer. This experiment was conducted from at experimental field of the Faculty of Agriculture, Universitas Padjadjaran to test the combination of soil conditioner, NPK fertilizer, nutrient solution (NS), and biofertilizer (BF) effects on soil biological and chemical properties and red chili growth. The experiment was designed using a Randomized Block Design with seven treatments and four replications. The treatments consisted of control, combination of NPK and NS with a dose of 0, 6, and 12 kg.ha-1 BF contained Azotobacter sp., Azospirillum sp., and Pseudomonas sp.. The doses used for a single application were 15 gplant-1 NPK and 300 mLplant-1 NS. Manure was applied to the control treatment and soil conditioner to the other treatments as a basic fertilizer at a dosage of 4 ton.ha-1. The results showed that the combination of soil conditioner, NPK fertilizer, nutrient solution, and biofertilizer had significant effects on soil biological properties and red chili growth, but didn’t show significant effect on soil chemical properties. The combination of soil conditioner + NPK + 12 kg.ha-1 BF increased soil fungal population (113,4 x 103 CFU.mL-1) and bacterial population (599,5 x 108 CFU.mL-1). Meanwhile, the combination of soil conditioner + NS + 6 kg.ha-1 BF increased plant height (60,48 cm).

Abstract

Lead (Pb) heavy metal pollution on rice fields in Rancaekek is caused by the disposal of textile industry waste which is not perfectly processed. The impact is a decrease in soil fertility which can threaten the food quality and agricultural sustainability. The application of N Bio-Organomineral fertilizer is one of the efforts to improve the quality of rice fields polluted with heavy metals Pb and high Na content. This research aims to find out the effect of N Bio-Organomineral fertilizer on pH, NO3-, Na, C-organic soil, solubility of soil Pb and uptake of plants Pb. The experimental design used a Randomized Block Design (RBD) with eight treatments and four replications consisting of: 0 (control); urea 250 kg/ha; and the variation in the dose of fertilizer is 250; 500; 750; 1000; 1250; 1500 kg/ha. N Bio-Organomineral fertilizer is a modification of N fertilizer based on urea, zeolite, activated charcoal and compost enriched with Bacillus subtilis with formulation 60:20:10:10. The results showed that the application of N Bio-Organomineral fertilizer could increase the NO3- and C-organic content of the soil and reduce the Na-dd and Pb uptake of plants. Treatment of 500 kg/ha N Bio-Organomineral fertilizer was the best dose in increasing the NO3- and Corganic content of the soil and reducing Na-dd and Pb uptake of plants

Abstract

Lithologic discontinuity reflects the distinct change between different types of soil layers that can occur due to various geological process, resulted in variation composition, colour, texture, organic matter, consistency, structure, and others characteristics. Soils derived from volcanic eruption have the possibility to have lithologic discontinuity in the depth of the soil profiles due to the different eruption that formed the soils. Soils developed from the eruption of Mt. Patuha were investigated whether lithologic discontinuity presence the soil layers. The research used descriptive and comparative method of two profiles, analysed the soil macro-morphology and soil laboratory analyses covered colour, organic carbon, texture, consistency and structure. The result showed that the unusual pattern distributed of colour, organic matter, consistency, structure indicated the lithologic discontinuities of the underlying 2Ab (A buried) horizon to the overlying horizon. The darker colour, higher organic matter content, friable consistency in 2Ab in deeper depth, were some indications of lithologic discontinuities, where in soil without lithologic discontinuities the deeper depth or horizon was normally lighter colour, lower organic matter content and firmer consistency. However, detailed analysed with instruments like XRF and VIS DRS are needed to have the precise elemental composition in every horizon which conclude the horizon from the same or different parent materials.

Abstract

Sustainable agriculture is the proper solution for improving the fertility of Inceptisol, which is potentially suitable for soybean cultivation. Balanced fertilization, using both inorganic fertilizers and nitrogen-fixing biofertilizers, is one appropriate solution. To enhance the effectiveness of nitrogenfixing bacteria, a suitable carrier material is needed. This study aims to assess the potential of different carrier materials for Azotobacter and Bacillus on the growth and yield of soybeans on Inceptisol in Jatinangor. The research employs a Randomized Block Design with two factors: NPK dosage (0%, 50%, and 100%) and Azotobacter sp. and Bacillus sp. in various carriers (compost, bran, and Azolla powder) with 3 replicates. The results indicate that the interaction of Azotobacter sp. and Bacillus sp. in carriers had no significant effect on the height and chlorophyll content of soybean plants. The 100% NPK dosage yielded the highest number of pods compared to the 50% and 0% dosages. The treatment of Azotobacter and Bacillus in carriers did not significantly affect the number of filled pods, plant height, or chlorophyll content.

Abstract

The Cikapundung Sub-watershed is part of the Upper Citarum Watershed, with its catchment area covering West Bandung Regency, Bandung City, and Bandung Regency. The increasing land use activities in the Cikapundung Sub-watershed have driven significant development activities in the upper areas of the subwatershed. One of the factors influencing this development is the road network, which affects the accessibility of an area, known as the driver variable. The creation of this driver variable requires GIS analysis using the Euclidean distance module, which calculates the distance from the roads. This calculation yields radial distances, ranging from the farthest to the nearest distances. It is known that local roads are the longest in the Cikapundung Sub-watershed, reaching 644.31 km. Based on the Euclidean distance calculation, the farthest distance from the road is 9504.22 meters, and the nearest is 0 meters. The map resulting from this calculation can be used to analyze the extent to which the distance from the road influences land use changes as a driver variable in the Cikapundung Sub-watershed.
