Answer:
Soil erosion.
Explanation:
No-till plowing can be defined as a farming method or technique which typically involves planting crops (seedlings) without tilling the soil rather the farmer would only open a narrow or very shallow trench of sufficient depth and width to cover up the seedlings. Thus, the no-till plowing makes crop residues to be left on the soil and by extension preventing soil erosion through the absorption of water by the crop residues.
Hence, by leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent soil erosion.
Additionally, the water retention ability of no-till plowing is usually a boon to farmers because it slows down evaporation and serves as a good protection for drought-stricken environments.

Noah's principle is a concept that comes from the Biblical story found in the old testament where God gave Noah instructions to build an ark to save him and his family .
The concept here is that God did not tell Noah when it was going to rain. The people of the day most probably mocked and derided Noah as a time waster or a fool. That is, until the flood came. The " fool" had been wiser all along.
An Application is this. Google gives everyone who does online business "suggestions" and "guidelines" but not everyone chooses to listen. Google rarely, if ever, tells us when they will put the guidelines into action.
Panda, a Google ranking system, took 6 years while Google was telling online users to follow certain guidelines. Many ignored, until Panda was put into action, and those who had not heeded suffered with only themselves to blame.
Moral: Heed and prepare even if the outcome tarries.
