California is dumping vast amounts of Ammonium Phosphate onto vast areas of land. They couldn’t collect runoff water because it’s detrimental to a fish. 

Now let’s take a look at the ramifications of dumping tons upon tons of Ammonium Phosphate: 

Dumping ammonium phosphate on a vast area of land can lead to several adverse ecological reactions:

1. Soil Degradation:
   - pH Imbalance: Ammonium phosphate can lower soil pH, leading to acidic conditions which may not be suitable for all plant species, altering the natural ecosystem.
   - Soil Nutrient Imbalance: An excess of phosphorus can lead to an imbalance of nutrients, inhibiting the uptake of other essential elements like iron, zinc, and manganese.

2. Water Pollution:
   - Eutrophication: Runoff carrying ammonium phosphate into water bodies can cause excessive algal blooms, leading to oxygen depletion in water (hypoxia), which harms aquatic life.
   - Harm to Aquatic Life: High levels of phosphates can be toxic to fish and other aquatic organisms, affecting their reproductive and developmental processes.

3. Impact on Plant Life:
   - Toxicity: Over-fertilization can lead to nutrient toxicity in plants, causing leaf burn, reduced growth, or death of vegetation.
   - Shift in Flora Composition: Favoring certain plant species that thrive in high-phosphate environments, potentially leading to a loss of biodiversity.

4. Microbial Community Disruption:
   - Changes in Soil Microbiome: The introduction of high levels of ammonium and phosphate can alter soil microbial communities, affecting processes like nitrogen fixation, decomposition, and nutrient cycling.

5. Air Quality:
   - Ammonia Volatilization: Ammonium can convert to ammonia gas, contributing to air pollution, which can have further implications for health and the environment.

6. Long-term Soil Health:
   - Salinity Increase: Over time, the salts in ammonium phosphate can accumulate, leading to soil salinization, which can degrade soil structure and fertility.

7. Wildlife and Ecosystem Health:
   - Alteration of Food Chains: Changes in plant species and soil conditions can affect herbivores, which in turn impacts predators, potentially leading to shifts in species populations or even local extinctions.
