1 LAND QUALITY INDEX

Land quality index was developed as an indicator of soil suitability based on the requirements

for perennial crop production. It enables FarmInfo users to do a comparative survey of the soil

suitability of farming units in South Africa as captured by the Surveyor General. The index is

particularly useful for comparing relative soil suitability – literally at a glance – between

neighbouring farms and to distinguish the location of highly suitable soil from those with low

suitability. The available report provides background information on the selected farm(s) in

tabular form for easy comparison.

1.1 Guidelines to interpret the land quality index

Land quality index (LQI) values above 70 suggests that a property has soils that are on average

rated as having a suitability of very high (the highest suitability class) for the production of

perennial crops (see Table 1). Usually such values are associated with soils that have specific

properties in terms of drainage class, depth, texture, etc. (excluding natural fertility) required

for the growing of perennial crops. A LQI of below 10 means that for all practical reasons the

soils of the property has (overall) a very low suitability (there might, however, be small areas

with higher suitability) for perennial crop production and therefore the production capacity

5 | P a g e

(potential) of the property is rated very low (the lowest possible suitability class), despite

reasons of a possible suitable climate or favourable terrain position(s) that it might have.

1.2 Definitions used:

“Agricultural potential” depends on the characteristics of land and management input. The

concept "land", as it is used here, refers to the space used on and under the earth's surface. It

has natural characteristics that include climate, soil, slope and vegetation. "Soil" is therefore

not synonym with "land" but is only one of its determining characteristics.

In terms of soil science the term "soil" refers to the surface layer of the earth’s crust. It is an

integral part of the landscape with properties, aspect and distribution that is determined by the

environmental factors e.g. climate, parent material, topography, flora, fauna and time.

The term "soil" as used here includes the morphological, physical, chemical and mineralogical

characteristics of the soil itself. It should therefore not be confused with the term "land”.

Agricultural potential reflects the production capacity of land under specific management

practices. Therefore, the individual components of land (soil, climate and topography or

terrain) do not have an agricultural potential but only suitability with respect to agricultural

activities. In this way a certain climate can be suitable for the cultivation of certain crops, but if

the soil is unsuitable, the potential is low. In the same way a certain soil can have all the

characteristics that make it suitable for the cultivation of a specific crop on a specific terrain,

6 | P a g e

but if the climate is unfavourable the potential is low. However, if the climate is favourable the

potential is high.

The term soil suitability (Farminfo prefers to use the term Land Quality Index) is thus used

here to refer to the capacity of the soil component of land. It excludes the influence of climate

and topography. Potential for agricultural production (production capacity) of a certain piece of

land can therefore only be determined if the suitability of soil, climate (including availability of

water) and terrain is known as well as the specific management conditions.

The maximum potential return or capacity of land can in practice only be achieved under

optimum management practices. These practices include, among others, fertilisation, tillage,

weed control, quality of seed, suitable implements, balanced capital investment and labour

expenditure with the correct balance amongst the respective farming enterprises.

1.3 Description of “Land Quality Index”

The land quality index map was based on the “Soil suitability map of South Africa, Version 1.0

(Lambrecths et al., 2011). The Soil Suitability Map of South Africa (SSMSA) is based on the land

type data of South Africa (scale 1:250 000) (Agricultural Research Council, 2010). An algorithm

was developed to rate each land type according to its suitability for perennial crop production.

The algorithm takes into consideration the individual soils within each land type, as well as the

texture and depth of each soil profile. The result of the algorithm is a soil suitability index

ranging from 0 to 100.

LQI (values in %) = (Area %) /100 * SSSR *10 * DT Rating (Table 2)

where

DT Rating = (D Rating + T Rating)/2 if Texture class = T1 or T2

or

DT Rating = (D Rating/2 + T Rating)/2 if Texture class = T3

Table 2 Abbreviations used to derive at the LQI algorithm with full explanation that follows below the

table

Area % A percentage area of a land type covered by a specific soil series.

SSSR Soil Series Suitability Rating (Individual series rated by a panel of experts and averages calculated)

D Rating Effective Soil Depth Rating

T Rating Texture Class Rating

Area %: A percentage area of a land type covered by a specific soil series.

A soil series is the basic unit of soil classification used during the Land Type Survey (Agricultural

Research Council 2010) being a subdivision of a soil form and consisting of soils which are

essentially alike in all major profile characteristics. It is the lowest category in a formal

classification system (Van der Watt and Van Rooyen, 1995).

7 | P a g e

SSSR: Soil series as reported in each land type was used for the soil series suitability rating and

evaluated by soil scientists in the Western Cape (and afterwards it was also verified for specific

areas outside the Western Cape where data were available for other parts of South Africa) in

terms of its suitability for the commercial production of irrigated perennial crops. The SSSR

ranges from 1 to 10, with 1 the lowest and 10 equal to the highest or best suitability. With the

experience and knowledge accumulated over the years by soil scientists in the different

production areas of the Western Cape, the SSSR can be seen as a reliable prediction of soil

suitability. The ratings can be interpreted according to the guidelines in Table 3.

Table 3 Interpretation of the soil series suitability rating (SSSR)

≤2 Very low Not recommended

>2 - ≤ 3 Low

>3 - ≤ 4 Low-medium Marginally recommended

>4 - ≤5 Medium Conditionally recommended

>5 - ≤6 Medium-high Recommended

> 6 High Highly recommended

D Rating: A soil characteristic frequently used in land suitability analysis is effective soil depth

or rooting depth. Effective depth (D) is the limit to where plant roots can penetrate soil material

to take up water, air and nutrients and consequently affecting soil and land suitability. Scotney

et al. (1987, revised 1991) defined five classes of effective soil depth for South African

conditions (Table 4) and the effective soil depth ratings that were used for the LQI calculation

are shown in Table 5.

Table 4 Boundaries for effective soil depth criteria

D1 Very deep >1000

D2 Deep 600 – 1000

D3 Average depth 400 – 600

D4 Shallow 250 – 400

D5 Very shallow < 250

Certain soil characteristics such as dense clay layers, weathering rock, bedrock, layering, and

signs of wetness, are fairly easily recognizable as limiting factors on effective soil depth. Some

soil characteristics such as acid subsoil or textural changes with depth are more difficult to

determine.

the classes shown in soil texture and sand grade diagrams

2 LAND TYPES

A Land Type (e.g. Ac27) is a map unit denoting land, mapable at 1:250 000 scale, over which

there is a marked uniformity of climate, terrain form and soil pattern (Agricultural Research

Council, 2010). Land Type information was used to interpret the soil series defined for each

Land Type that were used to derive at the Land Quality Index. The figures in brackets give the

approximate percentage coverage of a Land Type on the selected parcel of land.

3 CLIMATIC DATA

3.1 Chill units (h-1

)

A chill unit is a measurement allocated when temperatures are in between certain parameters.

Deciduous fruit trees require a certain period of winter chilling to complete their dormancy

during May to August. They require 200 – 700 positive chill units (PCU) or chilling hours. Every

hour of exposure to 18 °C or more will negate one chilling hour. The chill units (PCU) given

here might help to decide whether the property has the climatic potential to grow these crops.

Table 9 gives guidelines of Chill units for fruit trees (Schulze, 1997).

Table 9 Chill units for fruit trees

Apples and pears 800 - 1000

Apricots 400 - 600

Blueberries 220 - 600

Cherries >1000

Figs 200 - 300

Grapes 300 - 1000

Peaches and nectarines 200 - 300

Pecans 300 - 1120

Plums and prunes 300 - 750

Quinces 300 - 400

Walnuts 700 - 1400

3.2 Heat units (annual)

Heat units (expressed in degree days) above 10 °C. Heat units refer to the difference between

the average temperature ((maximum+minimum)/2) for the day and a base temperature (here

10°C) summed over the whole year. For example, if the threshold temperature is 10 °C and the

mean temperature of a given day is 20 °C, the degree days or heat units are 10 (20 – 10) If the

mean January temperature is 20 °C, the heat units will be 310 (20-10) x 31). There are certain

10 | P a g e

upper and lower temperature limits where crop growth is retarded or stops. Table 10 gives

guidelines on heat units for selected crops.

Sunflowers 10.0 30 1500

Sugarcane 12.0 35 2000

3.3 Frost (days)

The duration of the frost period is defined by Schulze (1997) as the number of days between

the average first date of heavy frost and the average last date of heavy frost. The figures given

(in days), does not imply that frost occurs on every day but only the number of actual days with

frost. A figure of minus 9999 means that no frost occurs.

3.4 Rainfall and Temperature

Mean and median annual and monthly rainfall (mm) and all temperature figures were obtained from

Lynch and Schulze (2006) and Schulze and Maharaj (2006) respectively.

4 GRAZING CAPACITY

Grazing capacity was obtained from the AGIS website. The map is a refinement of a draft

grazing capacity map that was produced by Pretorius in 2001 by correlating the maximum NDVI

image for 2000 with animal unit (AU) values from earlier (1993) grazing capacity maps.

Refinements took the form of incorporating land cover and tree density data.

5 VEGETATION TYPES

The vegetation types were obtained from the Vegetation Atlas of South Africa, Lesotho and Swaziland

(Mucina and Rutherford, 2006). A list of vegetation types occurring in South Africa, Lesotho and

Swaziland is shown in
