Wood Vinegar is a natural extract from woods. It is used in agriculture and animal fodders. It is a good choice for organic farming. The natural contents make it an attractive alternative to chemical pesticides and fertilizers. Furthermore it is non-toxic and biodegradable.
The concentration of agro-chemicals or liquid fertilizers can be reduced by 50% if it is diluted in a 500 times dilution solution of wood vinegar due to its higher permeation. This will greatly reduce the use of agro-chemicals.
There are many more benefits of wood vinegar that can be found within this website and we encourage you to explore and learn more about wood vinegar and its benefits.
Understanding the Negative Effects of Chemical Fertilizers
The effects of chemical fertilizers are not widely spoken about. This is partially because they are largely untested. We understand there is a risk of groundwater contamination and the environmental issues that brings, but we're still not entirely sure what it means for our own health, so other than trying to buy as much organic as possible, we just kinda shrug our shoulders at it.
To really understand this issue, we need to understand what chemical fertilizers actually do.
What Is Fertilizer?
Fertilizer is any substance used to add nutrients to the soil to promote soil fertility and increase plant growth. Notice how nothing in there mentions the actual soil health; that's because not all fertilizers are made the same and not all are healthy for the soil.
Soil health relies on a balance of macronutrients and micronutrients, as well as microbial health. It's vastly more complicated than simply adding nitrogen, phosphorus and potassium (NPK) to the ground and calling it a day.
Why doesn't this work? Because science doesn't always get it right. In the past scientists once thought food only consisted of macronutrients, but have since discovered micronutrients, antioxidants and so on. The same goes for soil health: scientists have focused almost exclusively on NPK since their "discovery" in the mid-1800s. It's this reductionist science that has us assuming we understand the chemistry of Nature and soil and thinking we can solve it with a quick application of chemical fertilizers.
Negative Effects of Chemical Fertilizers
The biggest issue facing the use of chemical fertilizers is groundwater contamination. Nitrogen fertilizers break down into nitrates and travel easily through the soil. Because it is water-soluble and can remain in groundwater for decades, the addition of more nitrogen over the years has an accumulative effect.
At the University of Wisconsin, Madison, they discovered the effects of chemical fertilizers are compounded when mixed with a single pesticide. They discovered altered immune, endocrine and nervous system functions in mice, as well as influence on children's and fetus's developing neurological, endocrine and immune systems. These influences "portend change in ability to learn and in patterns of aggression."
One popular fertilizer, urea, produces ammonia emanation, contributes to acid rain, groundwater contamination and ozone depletion due to release of nitrous oxide by denitrification process. With its increased use and projections of future use, this problem may increase several fold in the coming decades.
Groundwater contamination has been linked to gastric cancer, goitre, birth malformations, and hypertension; testicular cancer and stomach cancer.
Excessive air- and water-borne nitrogen from fertilizers may cause respiratory ailments, cardiac disease, and several cancers, as well as can "inhibit crop growth, increase allergenic pollen production, and potentially affect the dynamics of several vector-borne diseases, including West Nile virus, malaria, and cholera."
Perhaps one of the scariest effects of chemical fertilizers is something called methemoglobinemia. In infants it is alternatively known as Blue Baby Syndrome. The risk most often occurs when infants are given formula reconstituted with nitrate contaminated water. The condition causes a decrease in oxygen in the blood and results in a blue-grey skin color, causes lethargy and/or irritability and can lead to coma or death. I've been unable to find whether the same risk exists for breastfeeding babies whose mothers drank contaminated water.
Nitrogen groundwater contamination also contributes to marine "dead zones". The increase in the water-soluble nitrates creates an influx of plant-life, which eats up oxygen and starves out fish and crustaceans. This has an impact not only on the aquatic ecosystem, but on local societies who depend on food sourced from those areas.
Unfortunately, as unsustainable farming and gardening practices continue our soil is stripped of its health and we depend on amendments even greater. This leads to some pretty negative effects of chemical fertilizers.
Chemical Fertilizers Effects on Wildlife
The arrival of humans in an area, to live or to conduct agriculture, necessarily has environmental impacts. These range from simple crowding out of wild plants in favor of more desirable cultivars to larger scale impacts such as reducing biodiversity by reducing food availability of native species, which can propagate across food chains. The use of agricultural chemicals such as fertilizer and pesticides magnify those impacts. While advances in agrochemistry have reduced those impacts, for example by the replacement of long-lived chemicals with those that reliably degrade, even in the best case they remain substantial. These effects are magnified by the use of older chemistries and poor management practices.
