Poultry manure is highest in what nutrient?

  1. Phosphorus

  2. Potassium

  3. Nitrogen

  4. Calcium

The correct answer is: Nitrogen

Poultry manure is particularly high in nitrogen, which is a key nutrient essential for plant growth. The high nitrogen content in poultry manure comes from the proteins in poultry diets, and it's critical for promoting plant vitality and development. This makes it a highly sought-after fertilizer in agricultural practices. While phosphorus, potassium, and calcium are also present in poultry manure, nitrogen is typically the most abundant nutrient. This characteristic allows for effective utilization of poultry manure in enhancing soil fertility, particularly for crops that are nitrogen-hungry. Understanding the nutrient profile of poultry manure is important for farmers and agronomists to optimize fertilizer use and improve crop yields.
