Richard S. Fawcett, in The Triazine Herbicides , The problem of soil erosion into waterways has been correctly termed our most present form of water pollution Pimental et al. Soil erosion reduces water quality and disrupts agricultural sustainability. Crosson observed that though the public tends to be concerned about minute and innocuous quantities of herbicides in the environment, there is little awareness or concern about the threat of sediment damage to surface water quality.
Muddy water does not arouse moral indignation, even though its damage to the social welfare may be considerably greater than some other environmental threats. If so, the costs of the damage are consistent with the sustainability of the country's agricultural system.
Whether acceptance reflects full public awareness of the relative size of the sediment costs remains, for me, an open question. Soil erosion, therefore, is the greatest threat to the economic and environmental sustainability of United States agriculture Mueller, Pimentel et al. Erosion rates have exceeded replacement values on most sloping fields since the Europeans introduced plowing and grain farming as North America was settled.
Ten to 20 cm of topsoil enriched with organic matter, plus a suitable subsoil, are needed for efficient crop growth. Under the best conditions, nature needs 30 years or more to develop 2 cm about 3. The average annual loss of soil by erosion in the United States is about 1. However, erosion from sloping fields is often much higher, with losses exceeding 4.
Erosion rates exceeding T values are considered excessive. In addition to the long-term effects on topsoil losses, soil erosion also causes off-site impacts. Estimates for annual erosion damage categories are given in Table Eroded sediment carries most of the nutrients leaving farm fields.

Sediment also pollutes our rivers and water supplies with other natural toxins and biological contaminants. Table Estimates of annual off-site damage from soil erosion by damage category Riboudo, Sediment in rivers, streams, and lakes destroys aquatic habitats, decreases storage capacity of reservoirs, and interferes with navigational and recreational uses of water. The damage from sediments includes the loss of fish spawning sites, the cost of dredging ports and navigable rivers, and the cost of cleaning water for industrial and household users.
Conservation tillage is one of the most practical and economical ways to reduce soil erosion. Surface crop residue protects the soil from the erosive impacts of wind and rain.

Reductions in erosion are proportional to the soil coverage of crop residue. One or more of the triazine herbicides has served as an essential component of virtually all conservation tillage programs in corn, sorghum, and many other crops. Not only do conservation tillage systems greatly reduce the loss of valuable topsoil, but they also conserve much of the plant nutrients and organic matter that would otherwise be washed off the land along with soil to pollute our water systems further.

Ashley, in Food Security in the Developing World , The increased crop homogeneity has reduced the buffer of the crop to a disease outbreak, despite the multiline breeding techniques employed intended to confer disease resistance. This has led to the increased need for, and use of, fungicides. Little emphasis in the early GR was given to grain legumes pulses , which provide much of the protein in rural smallholder communities; thus hunger and food security was targeted more than was nutritional security.
Much of the land used for grain legumes that fed Indian subsistence smallholders was replaced by wheat which did not make up a large portion of their diet. A lot of this wheat was consumed by urban communities, or exported to the world market for grain or animal feed. Food and nutrition security for smallholders was therefore compromised. The reduced availability of pulses from subsistence agriculture has been blamed for the increase in undernutrition, the other side of the GR reduced-hunger coin.
It should be said that early GR improvements to the genetic base in wheat and rice was far easier than for grain legumes and corn. However, there was little improved germplasm available for beans or lentils or barley, sorghum, millet, potato or cassava. Even for corn, the more complicated mechanics of breeding and the high location-specificity of varietal technology made it difficult to adapt improved lines from the temperate zones to tropical climates and disease environments Evenson, So, that grain legumes were not at the forefront of GR advances cannot be blamed on Borlaug and his team.
As some micronutrient components of fertilizers are in relative short supply in the world, such as natural phosphatic rock, the increased use of this hastens the time when there will be none left or it is uneconomic to mine. Nitrogen fertilizers are products of the hydrocarbon industry, and oil and gas too are finite resources, their mining being unsustainable and their use responsible for greenhouse gas emissions and global warming.
