Decreasing Phosphorous in Farms

Farm lands have been relentlessly abused from storms recently. In an effort to retain precious phosphorous, farmers have had to change the practices they've followed for generations. It has been warned that phosphorus losses from the soil will continue to increase unless adjustments are made. Some options in reducing the amount of phosphorous runoff are: more sensible use of fertilizer to use soil  phosphorous or physical efforts. With the aid of the warm and wet winters, it is projected that there will be more runoff that will be led to rivers and effectively into the ocean. Farmers may be doing what they can to stop this but there is no way to stop 100% of the runoff. Nutrients such as phosphorous and nitrogen are essential to the growth of crops and livestock, yet too much can cause an abundance of algae. This Algal blooms can suffocate fish and demand remediation by water supply companies. Climate projections show that the largest contributing factor to increased future phosphorous loss is winter rainfall.

    This is a great article to emphasize the complexity of environmental problems. Farmers need the soil to have proper nutrients and cannot prevent nutrient run-off. Nutrient run-off can cause issues in local waterways. So how do farmers grow their crop and not cause algal problems? How can we stop disrupting the phosphorus cycle or help it to move properly? (Theoretical questions, no need to answer). :)

Dual-fuel vehicles

A recent study shows that dual- fuel vehicles are benefiting the population but, turns out they are costing the environment. While substituting gasoline for ethanol gases, it causes an increase of ultra fine particle matter, with a 30% increase of atmospheric concentration. The problem is that they are less then 50 nanometers in diameter. The nano particles are also not track or regulated by the environmental agencies. We inhale these gases everyday, inhaling ethanol. The most practical way to reduce greenhouse gases is using electric, hybrid and biofuel care.   https://www.sciencedaily.com/releases/2017/08/170828124546.htm

Acid Zone in Chesapeake Bay Found

     According to the University of Delaware, the Chesapeake Bay is becoming acidic as it has gone to 7.4 pH from an average of 8.2. The oxidation of ammonia and hydrogen sulfide may be the factor that is leading to the higher acidity levels in coastal oceans, but it can eventually lead to more of open oceans. Naturally the waters of the Chesapeake Bay have a regulatory system that holds back the increase of acidity levels in the area, and this works as the dissolving of living shells, non-living aragonite, and calcite minerals. Though nature has a path to keep the waters in the Chesapeake Bay, humans should take more care of our Earth as we have a role in polluting the water and rising the acidity levels in coastal oceans. https://www.sciencedaily.com/releases/2017/08/170828093737.htm
