Abstract

The proper understanding about spatial soil diversity is very important to simulate environmental model and to manage land resources in the landscape scale. Information of soil diversity is also noteworthy for environmental academics, forestry, civil engineering, and land use planner. Until now, most of the soil information are derived from conventional soil maps which are lack of detailed information. This condition can increase the uncertainty of model output and can also be an obstacle to the future development of spatial distribution model. According to this situation, the research was conducted in Sub Watershed of Cikeruh, Citarik, and Citarum Hulu. These areas are located in the 6o53’00”S - 6o53’15” S and 107o45’21”E - 107o45’55”E at 780-1800 m asl, The rainfall is classified as type C according to the Schmidt and Fergusson classification with mean rainfall around 1795.66 mm per year. The soils in the research areas are classified as Inceptisols.  The research aims to analyze and elucidate the relation between topographic characteristics and soil physical properties. Some parameters studied in this research are elevation, aspect, plan curvature, profile curvature, topographic wetness index (TWI), topographic position index (TPI), and some soil physical properties, such as soil texture (clay, silt, and sand), soil organic carbon, soil bulk density, soil available water capacity, soil porosity and permeability. The results showed that all topographic parameters were related to one or some soil physical properties, except aspect and slope. Topographic variables that are frequently related to soil properties are TPI and TWI. Keywords: topographic characteristics, elevation, aspect, curvature, TWI, TPI, soil physical properties

Abstract

ABSTRACT Andisols developed from parent materials of volcanic eruptions. Volcanic eruptions can occur within several periods, resulting in a sequence of soil layers that can differ from each period and produced lithologic discontinuity in the soil profile. Lithologicac discontinuity was investigated in Andisols developed from the eruptions of Mt. Tangkuban Parahu (Holocene, andesitic) and Mt. Tilu (Pleistocene, basaltic) in West Java through morphological observations of three profiles at each location. The results showed that there was lithologic discontinuity in all profiles indicated by changed in color by Munsell Soil Colour Chart, organic carbon, texture and structure as the specific A buried horizon that developed from the parent material of the earlier eruption period than the horizons above. It is recommended to carry out the mineralogical and micromorphological analyses to determine the differences in minerals and micromorphology of the discontinue horizons and carbon-dating analysis in the buried layer to determine the age of the soil and the period of eruption that developed the soil.Keywords: A buried horizon, Munsell Soil Colour Chart, organic carbon, soil mineralogy, soil morphology

Abstract

In the past decade, Indonesian interest towards sweet corn has increased. This condition creates a wide market opportunity for sweet corn. However, sweet corn cultivation in Indonesia is often constrained by low soil fertility. One of the essential nutrients needed by sweet corn is nitrogen. Nitrogen can be obtained from inorganic fertilizers such as Ammonium Chloride (NH4Cl) fertilizer. This research aimed to determine the effect and the best dosage of Ammonium Chloride (NH4Cl) in increasing N-total, N uptake, and yield of Sweet Corn (Zea mays saccharata Sturt) of Talenta variety on Jatinangor Inceptisol. This experiment was conducted at the research field of Soil Chemistry and Plant Nutrition, Department of Soil Science and Land Resources, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor from July to October 2020. The experimental design used in this research was Randomized Block Design (RDB), which consisted of nine treatments with 1 control treatment (without fertilizer), 1 standard single N, P, K fertilizer treatment, 3 dosages of Ammonium Chloride (NH4Cl) fertilizer treatment, and 4 combinations of Ammonium Chloride (NH4Cl) fertilizer with ¾ recommended dose of standard N, P, K fertilizer. The results showed that the combination of Ammonium Chloride (NH4Cl) fertilizer affected the total Nitrogen content, nitrogen uptake, and yield of sweet corn. Combination of 1 ¼ dose of Ammonium Chloride (NH4Cl) fertilizer with ¾ recommended dose of standard N, P, K fertilizer show the highest increase in total nitrogen (0,24%), nitrogen uptake (2,72 g per plant), and fresh weight of the corn cobs (0,42 kg per plant).

Abstract

This study aims to explain the influence of topographic attributes on soil texture classes using discriminant analysis. The topographic attributes considered in this study include elevation, slope, aspect, plan curvature, profile curvature, Topographic Wetness Index (TWI), and Topographic Position Index (TPI). The research location is the Sub Citarik Watershed, Upper Citarum Watershed, located at an altitude of 780-1800 m above sea level. The type of soil at the research location is Inceptisols. The results of the study show that topographic characteristics have a significant influence on soil texture classes. The discriminant analysis used in this study successfully classified soil texture classes with a reasonably high accuracy ((86,11%), although there is some room for improvement. This model shows good potential as a tool for predicting soil texture classes based on topographic characteristics, which can be used in various applications, including soil management and land use planning. The conclusion of this study highlights the importance of considering topographic attributes in soil management research and practice. Further research is suggested to improve the accuracy of the model and explore the use of this model in different contexts.
