To determine the best combination of soil type, soil pH, and amount of fertilizer for corn quality and yield, we should evaluate the test results you've provided.

Based on the provided tests:

  1. Soil pH:

    • Tests 2 and 3 have a pH of 6 (mildly acidic), and both are favorable for corn.
    • Test 4 and 5 have a pH of 7 (neutral), which can also be favorable.
    • Test 1 (pH 3) is highly acidic and is likely not suitable for corn.
    • Test 6 (pH 10) is highly basic and is also likely not suitable.
  2. Soil Nutrients (Fertilizer):

    • Test 2 has moderate nutrients with average crop quality, while Test 3 has high nutrients with good crop quality.
    • Test 4 has moderate nutrients with low crop quality.
    • Test 5 has high nutrients with moderate crop quality.
    • Test 1 and Test 6 both show low agricultural output and quality.

Considering these factors, here are recommendations for the best combination:

  • "Sand with a pH of 6 and high fertilizer" (Test 3): This combination showed high fertilizer with a pH of 6, resulting in good quality and high harvest potential.
  • The alternatives like "Sand with a pH of 7 with high fertilizer" could also be viable (though you didn't provide specifics for test results in this case) but slightly less favorable according to your previous results compared to test 3.

So, the best option for quality and amount of corn harvested would be:

Sand with a pH of 6 and high fertilizer.
