What was one of the reasons for the deterioration of the situation in agriculture in the USSR by the beginning of the 1960s?

The reasons for the crisis in agriculture that developed in the 1950s and early 1960s were the death of “the leader and father ..” I. Stalin. The threat of reprisals for non-fulfillment of the workday quota was eliminated. The collective farmers received passports and freedom of movement. Everything that was filmed about the excellent life in the collective farm is an agitation lie. People perfectly understood that the level of income and opportunities in the city is several times higher than in the village. The people began to leave the villages en masse. This was especially true for young people. The attempt to bring back labor in the “public economy” caused excitement among the inhabitants of the countryside. The demand for food was growing due to the increase in the population. People recovered from the war and began to multiply.
