Bikkurim2: 4
וְיֵשׁ בַּבִּכּוּרִים מַה שֶּׁאֵין כֵּן בַּתְּרוּמָה וּבַמַּעֲשֵׂר, שֶׁהַבִּכּוּרִים נִקְנִין בִּמְחֻבָּר לַקַּרְקַע, וְעוֹשֶׂה אָדָם כָּל שָׂדֵהוּ בִּכּוּרִים, וְחַיָּב בְּאַחֲרָיוּתָם, וּטְעוּנִים קָרְבָּן, וְשִׁיר, וּתְנוּפָה, וְלִינָה.
And there are laws which apply to bikkurim which are not so by terumah and maaser sheni: That bikkurim are acquired while attached to the ground; a person can make his entire field bikkurim; he is responsible for their replacement; and they require a sacrificial offering, song, ~waving, and staying overnight.
