A Compendium of On-Line Soil Survey Information Compiled by D. G. Rossiter

Department of Earth Systems Analysis University of Twente, Faculty of Geo-information Science & Earth

ObservationEnschede, the Netherlands

Soil is the thin skin of the Earth's surface where the atmosphere meets the lithosphere, hydrosphere, biosphere and of course the

anthrosphere. Soils vary tremendously in their properties and ecological function.

The job of soil survey is to map the distribution of the different soil types, describe these types, and interpret the maps in a form that is useful for land management and ecosystem studies. Systematic soil survey has been carried out for over one hundred years. As in other

applied sciences, conceptual and technological advances are making soil survey more reliable, cheaper and useful.

TUJUAN SURVEI TANAH

1. Systematic description and identification of soils properties

2. Soil classification3. study the pedogenic

processes4. Soil mapping5. Interpretation for

different land uses, including crop suitability, utility, soil management, soil productivity, soil quality,…


Klasifikasi TanahUsaha membeda-bedakan dan

mengelompokkan tanah berdasarkan sifat-sifatnya

TujuanMengetahui sifat dan ciri tanah pada masing-masing

kelompok tanah (kelas tanah) sehingga memudahkan pengguna tanah

untuk mengelola tanah tersebut agar dapat berproduksi secara optimal

Why Classify Soils?1. Organize knowledge to enable investigation and communication

(structure/organization)2. Provide framework for establishing relationships among

soils and their environment (scientific)3. Establish groupings for interpretations (utilitarian)

– Optimal use– Hazard/limitation/remediation assessment– Potential productivity– Framework for technology transfer/information dissemination

Survei Tanah (Bagian I: Kerapatan Pengamatan setiap Survei)by Dr. Ir. Abdul Madjid, MS

Berdasarkan intensitas pengamatannya, survei tanah ada 6 tingkatan, yaitu:(1) Bagan,(2) Eksplorasi,(3) Tinjau,(4) Semi Detail,(5) Detail, dan(6) Sangat Detail.

Survei Tanah Tingkat Sangat Detail:

Survei tanah tingkat sangat detail mensyaratkan pengamatan lapang dengan tingkat kerapatan pengamatan lapangan: 2 titik pengamatan untuk setiap 1 hektar; kisaran skala yang dihasilkan antara: 1 : 10.000 atau skala

yang lebih besar. Pada umumnya skala yang dihasilkan adalah 1 : 5.000; sehingga memiliki luas tiap 1 cm2 pada peta adalah 0,25

hektar; Satuan peta yang diperoleh adalah: Konsosiasi; satuan tanah yang ditampilkan adalah Fase dari Seri.

Contoh penggunaan peta tanah ini adalah untuk Perencanaan dan pengelolaan lahan di tingkat petani, penyusunan rancangan usaha tani konservasi; intensifikasi penggunaan lahan kebun.

Geostatistical analyses and hazard assessment on soil lead in Silvermines area, IrelandDavid McGrath, Chaosheng Zhang, Owen T. Carton

Environmental Pollution. Volume 127, Issue 2, January 2004, Pages 239–248.

Spatial distribution and hazard assessment of soil lead in the mining site of Silvermines, Ireland, were investigated using statistics, geostatistics and geographic information system (GIS) techniques.

Positively skewed distribution and possible outlying values of Pb and other heavy metals were observed. Box–Cox transformation was applied in order to achieve normality in the data set and to reduce the

effect of outliers.

Geostatistical analyses were carried out, including calculation of experimental variograms and model fitting. The ordinary point kriging estimates of Pb concentration were mapped.

Kriging standard deviations were regarded as the standard deviations of the interpolated pixel values, and a second map was produced, that quantified the probability of Pb concentration higher than a

threshold value of 1000 mg/kg. These maps provide valuable information for hazard assessment and for decision support.

SATUAN PEMETAAN TANAH• Definition: a collection of areas defined and

named the same in terms of their soil components or miscellaneous area or both.

• Soil series (or soil types, or soil phase) as a mapping unit in Taiwan rural soils

• Soil complexes : Two soil series in one mapping unit for detail soil survey (>1:24,000)

• Soil association : Two soil series in one mapping unit for reconnaissance soil survey (<1:24,000)


A pedon is a three-dimensional sample that extends from the soil surface to the deepest

roots or genetic soil horizons. The area covered by a pedon varies from 10 - 100

square feet, depending on changes in soil properties. Groups of pedons with very similar characteristics that are closely associated in the landscape are called polypedons. Polypedons that have a

common set of characteristics that fall within a particular range are referred to as a soil series (Brady and Weil, 1999). Soil series

are the basic units used by the U.S.D.A Natural Resources Conservation Service to

map soils within the United States.

PERLENGKAPAN SURVEI TANAH• Spades, shavels, picks, and bars• Soil Augers or tubes• A pickup truck with a power probe and a tool compartment mounted in the back.• A backhoe mounted on the rear of a small tractor• A powerful auger mounted on a pickup truck• a sampling tube mounted on a pickup truck• all-terrain vehicle


How to collect a soil sampleYour objective is to collect 15 to 20 cores from the area to be sampled (Figure 1). You need to collect more cores

per field in a pasture than in a row-crop field because there typically is much more variation in a pasture from manure piles and urine spots.

The best approach is to travel across the entire area to be sampled in a zigzag pattern, randomly selecting spots to take a core (Figure 1). Sampling depth is 6 to 7 inches for most objectives in pastures (Figure 2). Do not take too

shallow a sample as this will overestimate the soil fertility level in your pasture.

INTERPRETASI TANAH1. Soil management groups2. National specific-use placements including limitation ratings, suitability rating, ……

3. Local relative placements4. Interpretive soil properties for soil and crop quality


Land EvaluationThe main activities in a land evaluation are as follows:1. Initial consultations, concerned with the objectives of the evaluation, and the data and assumptions on

which it is to be based2. Description of the kinds of land use to be considered, and establishment of their requirements3. Description of land mapping units, and derivation of land qualities4. Comparison of kinds of land use with the types of land present5. Economic and social analysis6. Land suitability classification (qualitative or quantitative)7. Presentation of the results of the evaluation.

The identification and description of the type" of land use which are to be considered is an essential part of the evaluation procedure. Some restrictions to the range of uses relevant for consideration will have been

set by the objectives and assumptions. Two situations may be distinguished:8. The kinds of land use are specified at the beginning of the evaluation procedure.9. The kinds of land use are broadly described at the beginning and subject to modification and adjustment

in accordance with the findings of the evaluation procedure.

INTERPRETATIVE APPLICATIONS National Inventory grouping Land use planning farmland, rangeland, forest lands, windbreaks, recreation, wildlife habitat, construction

materials, building sites, waste disposal, water management, ……...• Soil management grouping


Matching of Land Use with LandMatching represents the essence of the interpretative step following the resources surveys in the land

evaluation procedure, and is based on the functional relationships that exist between the land qualities, the possibilities for land improvement and the requirements of the land use.

In its simplest form matching is the confrontation of physical requirements of specific crops (or grasses, trees, etc.) with the land conditions to give a prediction of crop performance. Matching becomes more

complex when the production factor is complemented by other performance conditioning characteristics of the land utilization type, including non-physical aspects like labour intensity and capital intensity.

Among the purposes served by matching are:1. To check the relevance and refine the descriptions of land utilization types2. To permit systematic determination of the management and improvement specifications of each land

utilization type on each land mapping unit to which it is suited, and thus of the required inputs (in terms of capital, labour, etc.)

3. To estimate the magnitude of the benefits from each land utilization type on each suitable land mapping unit.

SISTEM INFORMASI TANAH• Use of soil survey information• General soil maps• Technical reports• Automated soil data bases for soil interpretation and computer storage for land planning and soil

management


Mapping Technology

Mapping Technology is a combination of the fields of cartography and geographic information

systems.

The program at Mansfield provides a strong background in map design and compilation as

well as a good understanding of data management and an introduction to

programming.

The curriculum requires courses in map reading and air photo interpretation, remote sensing and GIS as well as the series of cartography

courses. Graduates of this relatively new program

(established in 2000) work for engineering firms, mapping firms and local and regional

government offices.
