This “leaky system” refers to what is not absorbed by the crops on the field, most dangerously, in this case, fertilizer. “It’s
Because like the Dust Bowl of so many decades ago, this tragedy stemmed from a collision of multiple systemic problems—in this case, unchecked climate change layered atop the excesses of industrialagriculture. Fertilizer runoff can also affect urban communities downstream.
Industrialagricultural practices such as tillage (plowing) and leaving fields bare between growing seasons degrade soil structure, reduce water infiltration, lower water storage capacity, and increase runoff (the flow of water across the soil’s surface).
However, industrialagriculture — characterized by the use of heavy tillage, intensive monocropping, and excessive grazing — has resulted in the degradation of the very soils that sustain our food supply. ‘No-till’ The land is a constant, withstanding generational change in personnel, methodology, and even land use.
These practices include reducing or eliminating tilling of soil, planting “cover crops” that grow during the off-season and are not harvested, improving how farmers use fertilizer and manure, and planting trees. The main greenhouse gases emitted by U.S. Both warm the atmosphere far more, per molecule, than carbon dioxide.
