As an agricultural expert with a focus on crop yield and farming practices, I can provide you with a detailed answer to your question about the number of round bales of hay that can be obtained from an acre.

Firstly, it's important to understand that the yield of hay from an acre can vary significantly based on a number of factors. These include the type of grass or legume used, the fertility and quality of the soil, the amount of rainfall or irrigation received, and the farming techniques employed. The density of the hay also plays a crucial role in determining how many bales can be produced.

The rule of thumb mentioned in your reference, that one tonne of hay is roughly equivalent to 40 to 45 bales, or 4 to 5 round bales, is a reasonable starting point. However, this is a general estimate and can vary. For instance, if the hay is packed more tightly, you might get fewer bales per tonne, and vice versa.

Now, let's consider the yield per acre. The reference suggests that an acre might yield approximately two tonnes of hay. If we take the average of the range provided for bales per tonne, which is 42.5 bales (the midpoint between 40 and 45), then two tonnes would yield approximately 85 bales. However, this is a very rough estimate and actual yields can be much higher or lower depending on the factors mentioned earlier.

In more fertile regions with good farming practices, an acre might yield more than two tonnes of hay, potentially leading to over 100 round bales. Conversely, in less favorable conditions, the yield could be significantly less.

It's also worth noting that modern farming equipment and techniques can influence the yield. For example, the use of high-quality seed, proper fertilization, and timely mowing can all contribute to a higher yield. Additionally, the method of baling can impact the number of bales produced. Some farmers opt for larger bales to reduce the number of bales they need to handle, while others may choose smaller bales for easier storage and transport.

In conclusion, while the rule of thumb provides a useful starting point, the actual number of round bales of hay that can be obtained from an acre is highly variable and dependent on a multitude of factors. It's always best to consult with local agricultural experts or conduct your own yield trials to get a more accurate estimate for your specific situation.
