What is the likely outcome of applying sulfur (S) to a soil with high base saturation and alkaline pH?
Understand the Problem
The question is asking about the effect of adding sulfur to soil with high base saturation and alkaline pH. The key concept here is how sulfur influences soil pH and salinity based on the initial soil conditions.
Answer
Applying sulfur will likely lower the soil's pH by converting it to sulfuric acid.
Applying sulfur to soil with high base saturation and alkaline pH will likely result in a reduction of soil pH. Soil bacteria will convert the sulfur into sulfuric acid, which lowers the pH. It can also help reduce sodium uptake in plants.
Answer for screen readers
Applying sulfur to soil with high base saturation and alkaline pH will likely result in a reduction of soil pH. Soil bacteria will convert the sulfur into sulfuric acid, which lowers the pH. It can also help reduce sodium uptake in plants.
More Information
The amount of sulfur needed depends on the initial pH, soil type, and desired pH level. Regular soil testing is recommended to monitor pH changes and ensure optimal levels for plant growth.
Tips
Applying too much sulfur can lead to excessively acidic conditions, which can harm plants. It's important to follow soil test recommendations and apply sulfur carefully.
