Tracking the recent farm runoff legislation strategies in Iowa and Minnesota, it becomes clear – to the surprise of few – that attempts to formalize legislation aimed at curbing farm runoff will be met with staunch resistance.
This does not bode well for residences amongst and downstream of agricultural operations. Such operations continue to struggle with controlling the runoff they create from excessive animal manure.
practices for reducing farm runoff. Ag runoff, as has been mentioned many times here, is the primary contributor to harmful algae blooms (HABs). As ever, best practices always include creating sizable grass buffer spaces between cropped land and waterways.
Grass which carries a clear benefit for farmers. It can (and should) be harvested to feed and bed farm animals.
Such a basic strategy makes great sense when proposed in a vacuum. But, for farmers striving to pull every bit of revenue from each acre, such an approach may not always make financial sense. And, clearly, farmers have little interest in more governmental involvement — as is presented regarding Iowa legal battles in this recent article from US News and World Report.
The push-and-pull here is inevitable, oh-so predictable, and the least productive method for solving the nationwide and global challenge of HABs.
As Spring soon rolls into the Midwest, the ugly reality of melting snow across hundreds of thousands of manure fertilized fields again manifests. And the picture is not pretty.
In recent years Lake Erie has experienced Harmful Algae Blooms (HABs) larger than the size of New York City. Most of this pollution — which comes in the form of phosphorus — empties into the Western Ohio part of the Lake via the Maumee River basin.
Since the Cuyahoga River Basin contains over 15%, or nearly 2,000,000 people, of the State of Ohio’s population, it is popular to contend that these cities are responsible for the pollution. But this argument falls flat, according to a report from LakeErieAlgae.com.
The differences in how heavy spring rainfalls affect phosphorus loads in two watersheds – the Maumee and the Cuyahoga – show the different impacts of non-point sources (like the primarily agricultural lands in the Maumee River basin) and point sources (like the urban and industrial lands in the Cuyahoga River basin, which houses nearly 15% of Ohio’s population). Both watersheds occasionally have combined sewer overflows (CSOs), but research suggests these volumes pale in comparison to the river volume during storms.
In short, the Maume River, flowing through the mostly agricultural Maumee River Basin, is responsible for the vast majority of the phosphorus pouring into Lake Erie. And this phosphorus is the key trigger to HABs.
Watch closely as Spring 2017 approaches. HABs will result no matter what but, should heavy rains accompany the annual melting of snow, record HABs will again be reported across not just Lake Erie, but throughout the USA and beyond.
This excellent report from The National Wildlife Federation (NWF) offers numerous touch points on how to curb HABs, like the below:
We need increased actions to address nonpoint source pollution, in particular agricultural runoff. This includes increased targeting of Farm Bill and other programs to priority areas, and continuing research to identify key nutrient source areas.
Summer HABs will be explained in no small part by Spring meltdown and precipitation levels.
The inauguration of United States’ 45th President Donald J. Trump represents America’s ceremonial yet very real transfer of presidential power. In his address, President Trump promises among things to “never let (Americans) down.” His vow to bring back jobs, and rebuild infrastructure by improving roads, schools, bridges, airports, etc., is a bold one.
Although it is likely few Americans expect a shiny new country four years from now, the success of President Trump’s administration will be measured by bricks and mortar — upgraded and replaced from the labor of American hands. Should he fall flat on this great promise, clearly he will have let down US citizens.
It is not necessarily alarming that nowhere in President Trump’s speech was there the mention of clean water. Surface and ground water problems are often local, and governing clean water issues is generally left to area, regional, and state government.
But this year, when Toledo, OH (again) cannot tap drinking water; when Waukesha County, WI, (again) cries out for freshwater from Lake Michigan; when a proliferation of lakes and rivers all across the USA (again) fill with Harmful Algae Blooms (HABs) — threatening the health and well-being of tens of millions of Americans — the United States’ freshwater crisis will (again) emerge. The crisis already exists in pockets throughout the USA and, in President Trump’s tenure, it will likely become a highly visible federal government priority.
Rewarding farmers, long-term and permanently, for implementing best practices is key to in any meaningful way cleaning up surface water. Farmers must be willing to accept the reality that economic and land-management changes to their operations are necessary, and must now be implemented. Government, working with nimble non-profits like Clean Water Warrior, must be swift in providing resources to assist and reward farmers making these best-practice changes.
It will be an interesting four years. President Trump – the stage is yours.
The term “point source” means any discernible, confined and discrete conveyance, including but not limited to any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, or vessel or other floating craft, from which pollutants are or may be discharged.
Importantly, point pollution does not include agricultural storm water discharges and return flows from irrigated agriculture. Otherwise known as farm runoff.
Point pollution, often to the surprise of many, also does not account for the vast majority of surface water pollution across the USA and elsewhere. That responsibility lies with agriculture, and farm runoff.
In this 2014 Scientific American article, Lake Erie Basin farm fields are cited as being responsible for at least 60% of the phosphorus now reaching Lake Erie. Phosphorus is the key nutrient feeding the epic algae blooms occurring annually in the lake. This 60% figure is tossed around regularly — in many places the percentage is as high as 80% — wherever and whenever agriculture, algae blooms and phosphorus are discussed.
Conservation Tillage – leaving crop residue (plant materials from past harvests) on the soil surface reduces runoff and soil erosion, conserves soil moisture, helps keep nutrients and pesticides on the field, and improves soil, water, and air quality; Crop Nutrient Management – fully managing and accounting for all nutrient inputs helps ensure nutrients are available to meet crop needs while reducing nutrient movements off fields. It also helps prevent excessive buildup in soils and helps protect air quality; Pest Management – varied methods for keeping insects, weeds, disease, and other pests below economically harmful levels while protecting soil, water, and air quality; Conservation Buffers – from simple grassed waterways to riparian areas, buffers provide an additional barrier of protection by capturing potential pollutants that might otherwise move into surface waters. Strategic Irrigation Water Management – reducing non-point source pollution of ground and surface waters caused by irrigation systems; Grazing Management – minimizing the water quality impacts of grazing and browsing activities on pasture and range lands; Animal Feeding Operations (AFOs) Management – minimizing impacts of animal feeding operations and waste discharges through runoff controls, waste storage, waste utilization, and nutrient management; Erosion and Sediment Control – conserving soil and reducing the mass of sediment reaching a water body, protecting both agricultural land and water quality and habitat.
The new year has arrived. Here’s hoping it will be a good one for everyone — starting with the water we share.
