TLDR is maybe this [2] write-up of a talk, 8 pages, very interesting.

I think they produced too little and at some point the US wheat market became off-limits for them. There's this Wikipedia article [1] stating how because of a failed crop the URSS basically bought everything they could get their hand on from the Chicago Mercantile Exchange (this was happening in 1972), and I also found this 1982 Foreign Affairs article [2] that detailed the reasons why URSS had become a net grain importer by that time. Also, apparently Russian PM and economist Yegor Gaidar said that the fall of the URSS was partially caused by the "wheat situation", combined with a decrease in the price of oil in the 1980s [3]
> But there was a more immediate explanation for the collapse of the Soviet Union provided by Yegor Gaidar, who had been acting prime minister of Russia from June of 1992 to December of 1992 and a key figure in the transformation of the Russian economy. In his last work, Collapse of an Empire: Lessons for Modern Russia, published in 2007 Gaidar provides a powerful explanation for the collapse of the Soviet Union. Soviet agriculture had stagnated in the 1980's but the demand for grain in the cities was increasing. It was necessary to buy grain in the international market. While the price of petroleum was high it was feasible to finance the purchase of grain from internal sources. When the price of petroleum fell in the late 1980's the Soviet Union needed to borrow the funds from Western banks to purchase the needed grain. This severely restricted the international activities of the Soviet Union. It could not send in Soviet troops to put down the rebellions against communism in Eastern Europe because such an action would have resulted in a refusal of Western sources to lend the money needed. Likewise the attempted coup d'état was doomed to failure because the coup leaders would not have been able to borrow the funds needed to stave off starvation in the major cities.
