Why is oranges added to soil?

Oranges and other citrus peels are often added to soil as they can improve its nutrient content and enhance microbial activity. The organic matter from the peels decomposes, enriching the soil with essential nutrients like nitrogen, potassium, and phosphorus. Additionally, the acidity of orange peels can help lower soil pH, benefiting certain plants that thrive in more acidic conditions. This practice can also help with pest deterrence and attract beneficial insects.
