{'reactive nitrogen': [0, 0, 0, 1], 'agricultural soils release nitrogen': [0, 0, 0, 1], 'ammonia': [0, 1, 0, 2], 'environment': [2, 0, 0, 3], 'poultry industry': [0, 0, 0, 1]}

All the three statements given in the question are correct.

Option 1 suggests that agricultural soils release nitrogen oxides into the environment. This is true as nitrogen oxides are produced during the microbial process of nitrification and denitrification in the soil.

Option 2 states that cattle release ammonia into the environment. This is also true as ammonia is a by-product of the metabolic processes in cattle and is released into the environment through their urine and feces.

Option 3 asserts that poultry industry releases reactive nitrogen compounds into the environment. This is again true as poultry waste contains reactive nitrogen compounds, which can be released into the environment.

Therefore, after analysing each statement, we can conclude that option 4, confirming that all the three statements are correct, is indeed the right answer.
