Site¶
The site tab is used to capture metadata about your LTE’s location and environment.
Site Location¶
Mandatory fields¶
- Site Name
- This is the name by which your experiment site is commonly known. This can be the same as the experiment name.
- Site Latitude and Site Longitude
The site latitude and longitude provide a point location for your LTE site and are required for adding your LTE to the https://glten.org LTE map.
The site latitude and longitude must be provided in decimal degrees, not degrees, minutes and seconds. If you do not know your LTE site location coordinates as decimal degrees you can use https://www.latlong.net/ to find your site on a map then copy and paste a point coordinate.
Protecting farm privacy. For LTEs sited on research institute or university farms, GLTEN recommends providing precise coordinates for the field site. However, if the LTE is located on a private farm you can provide less precise coordinates.
Soil Information¶
Mandatory fields¶
- World Reference Base dominant soil type
This is the World Reference Base dominant soil type for your site and provides a useful indicator of soil properties.
If you do not know the WRB soil type for your site, either use https://soilgrids.org to identify a predicated class for your location, or select the Don’t know option from the drop down list.
Recommended fields¶
- Soil description
- You can use the soil description text box to provide a text description of your soil. If you have measured properties, such as bulk density or SOC, use the Soil Properties list to add them.
- Soil properties
You can use the soil properties section to add more detailed soil physics and chemistry information such as sand content; soil organic carbon; Olsen P in soil. There is no limit to the number of soil properties you add.
For each soil property you can add the following information:
- Soil depth: provide a minimum and maximum range for the soil depth the property refers to. If you only have one depth value, enter it in the minimum depth field
- soil depth units.
- Is baseline: indicates whether the soil property was measured at baseline, i.e. before the LTE started.
- Reference year: the year when the soil property was sampled/measured.
- Is estimated: Check this box to indicate the property has been estimated i.e using a model. This may be the case for baseline values from older LTEs.
- Typical: this is an average value for the soil property.
- Minimum and Maximum: this is the range of values for the soil property.
- Units: the measurement units for the soil property.
Climate Information¶
Mandatory fields¶
- Köppen climate classification
This is the Köppen climate classification for your site and provides a useful indicator of climate poperties.
If you do not know the classification for your site, either use maps at Köppen Climate climate classification to identify the class or select the Don’t know option from the drop down list.
Recommended fields¶
- Climate Description
- You can use the climate description text box to provide a description of your climate. If you have measured properties, such as temperature or rainfall, use the Climate Properties list to add them.
- Climate properties
You can use the climate properties to add detailed climate information, for example rainfall or temperature. It is recommended to use averged annual properties (i.e. annual precipitation).
For each climate property you can add the following information:
- Start year and End year: to indicate the period of years the property refers to.
- Mean: value of the period.
- Minimum and Maximum values: for the period.
- Units: the measurement unit for the climate property.
