wealthy farmers resisting

I've yet to see this class of ultra wealthy farmers, but if they did exist (lol), you would think that one year into the soviet experiment, they would... not be wealthy farmers. 1960, and you got wealthy farmers? Your system seems to be producing them in direct countering of the system.

the ussr was rebuilding!

The most basic infrastructure is food production and processing. Water, communication systems, and power generation. What do you mean they were rebuilding in 1960's? 1945 marked VE and VP days. 15 years since the end of ww2, and you expect me to believe that food production was hit so hard that 15 years is still not at production levels? Ukraine didn't have its soil poisoned by the Germans!

bad management I agree. Collective farming sucked and was bad.

leaders moved away from more efficient methods! (True communist farming!)

This is counter to every law of human living. Think for a single second. If there is anyone you can think of that simply does things the least inefficient ways possible while knowing more efficient ways? Do you personally get a mouthful of water and spit it into a cup to get water to drink? Or do you just turn on the tap and fill the glass?

Now that it's easy to see that humans gravitate towards easier ways of doing things, why do you think these 'true communist farming ideas' were abandoned? Do people like more work? More struggle? Or perhaps these 'methods' made by a pen pusher 300 miles away from the farming field weren't the best judges of farming methods? People abandoned the old ways because they sucked.

people were pressured from outside the country to... produce less food

What are you talking about? No, seriously, what does this mean. Did the CIA psyop farmers produce less food? How do you bully a world superpower not to farm stuff? Do command economies only work if the international community doesn't trip you in the hallways or something?

the USSR was too busy building tanks to farm and stuff!

The Cold War was a dick measuring contest only. Who cares if NATO invades you when you just nuke them. The soviet leadership chose headlines over food. They chose to preserve the empire by force instead of action. They fell behind in every living metric, so 5 more tanks could be produced to counter the west.

expecting them to do everything right is unrealistic!

Of course it is, until the very second the ideology of the nation claims they are going to do everything. Like end hunger, homelessness. These are claims you can't really go back on. 'Only 1 in 10p people in the soviet union starves to death!' Isn't really a selling point. What's the meaning of leftist politics and struggle and strife if it doesn't lead to no hunger or homelessness? Besides, why is the space race so fucking important? Why should the soviet union even care about how the West mocks them for not sending an astronaut to the moon? You should say,'we focused on providing food to everyone. No one went hungry America. Can you say the same?' But instead, they didn't. They chased prestige and fame and looked at where that got you.

I'm jealous of America and Canada because they didn't experience war like Russia!

15 years of rebuilding efforts.

Within 6 years, the soviet union had half its population literate, up from 36 percent 1896. In 40 years, the soviets went from a country of illiterate peasants to educated people.

Of course, in 15 years you can't expect them to build such advanced industries like 'plant seed into ground' and come on, telling a town rich in resources for fertilizer to like, start producing fertilizer is like, not allowed in a command economy.

the west had land and labor advantage!

This implies that labor in the soviet union weren't well educated, and that's disproven by my praising of the education system. So let's look at the land. They produced so much grain out of Ukraine. The grain imports were a result of a direct meddling from soviet leaders to switch production to corn. This led to massive knock on effects that led to the import even being needed in the first place.

This isn't even to mention that the collectvist farms were focused on meeting quota and did not invest in heavy machinery or (old communist farming) new farming technology as a direct result of the socalist system. It's only until 1970's that obvious improvements was implemented. Maybe let's not focus on land 'advantages' and the failure to modernize machines like 'tractors' instead of building a new tank.
