The lecture criticizes the plow, thus the points in the lecture challenge points in the reading.
First, according to the lecture the plow increases crops, but does not conserve for the future. The professor discussed alternating and no till farming, which is better. This is contrast with the reading that the plow is a great invention because it makes possible large-scaled land agriculture so it provides vast of the crops.
Second, the lecture state the overuse of the plow damage to the soil. For example professor said it causes erosion by the wind and water. In the following of the lecture professor state dust bowl, wind dust storm and run of the soil into the lake and river happened while the plow are extremely. This challenges the point in the reading that tilling soil with a plow improves the soil.
Furthermore, professor in the lecture states that no till farming leaves crops residues on the field, and after a time decomposes completely, consequently this improve the soil however, This is contrast with the passage that state plowing incorporates these residues in to the soil. In addition, tilling loosens and weaken the soil.
Third, the professor mentioned the economic advantage of no till farming. He believed its leads to save fuel and labor costs but passage state the plow reduces the costs and labor requirements of agriculture.
