In a televised interview, Foreign Minister Mevlut Cavusoglu said Lavrov would arrive in Turkey on June 8 "for talks on the issue of opening a security corridor that also includes (shipping) of wheat in the Black Sea."
Cavusoglu said: "This is the most important question. We are focussing on this. We are planning to establish a centre in Istanbul to observe the corridor."
Lavrov will be accompanied by a military delegation, he added.
The announcement comes a day after Russian President Vladimir Putin told Turkish counterpart Recep Tayyip Erdogan that Moscow was ready to work with Ankara to free up maritime shipping blocked over the conflict.
The Russian leader said the readiness of the Russian side "to contribute to the unimpeded maritime transit of goods in coordination with Turkish partners. This also applies to grain exports from Ukrainian ports," the Kremlin quoted Putin as saying in a readout of a call with Erdogan.
Russia's offensive in Ukraine and Western sanctions have disrupted supplies of wheat and other commodities from the two countries, fuelling concerns about the risk of shortages and hunger around the world.
Russia and Ukraine produce 30 percent of the global wheat supply.
Dozens of container ships are blocked in Ukrainian ports that are surrounded by Russian forces, choking off exports of wheat, sunflower oil and other foodstuffs, as well as fertiliser for crops.
Black Sea navigation has also been hampered by mines placed by both Russian and Ukrainian forces.
