As suggested by others why would you want to set limits for root? If you limit root you risk locking yourself out of the OS. Any applications running should run as a user created for the task, you can then apply limits to that user to protect the servers performance without risking blocking the root user.
Just today we had an application spin out of control and hit the limit of processes for the user account which had started the application. This meant that application support could not login to the server, but as root I was able to login and kill the rogue process.

xdg-settings
XDG-SETTINGS(1) xdg-settings Manual XDG-SETTINGS(1)
NAME
xdg-settings - get various settings from the desktop environment
SYNOPSIS
xdg-settings {get | check | set} {property} [subproperty] [value]
xdg-settings {--help | --list | --manual | --version}
DESCRIPTION
xdg-settings gets various settings from the desktop environment. For instance, desktop environments often provide proxy configuration and
default web browser settings. Using xdg-settings these parameters can be extracted for use by applications that do not use the desktop
environment's libraries (which would use the settings natively).
xdg-settings is for use inside a desktop session only. It is not recommended to use xdg-settings as root.
OPTIONS
--help
Show command synopsis.
--list
List all properties xdg-settings knows about.
--manual
Show this manual page.
--version
Show the xdg-utils version information.
PROPERTIES
When using xdg-settings to get, check or set a destkop setting, properties and possibly sub-properties are used to specify the setting to
be changed.
Some properties (such as default-web-browser) fully describe the setting to be changed. Other properties (such as
default-url-scheme-handler) require more information (in this case the actual scheme to set the default handler for) which must be provided
in a sub-property.
EXIT CODES
An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned:
1
Error in command line syntax.
2
One of the files passed on the command line did not exist.
3
A required tool could not be found.
4
The action failed.
EXAMPLES
Get the desktop file name of the current default web browser
xdg-settings get default-web-browser
Check whether the default web browser is firefox.desktop, which can be false even if "get default-web-browser" says that is the current
value (if only some of the underlying settings actually reflect that value)
xdg-settings check default-web-browser firefox.desktop
Set the default web browser to google-chrome.desktop
xdg-settings set default-web-browser google-chrome.desktop
Set the default mailto URL scheme handler to be evolution.desktop
xdg-settings set default-url-scheme-handler mailto evolution.desktop
