Are manures not nutrient specific

Manures are generally not nutrient-specific; they contain a broad range of nutrients, including nitrogen, phosphorus, potassium, and various micronutrients. The nutrient composition can vary significantly depending on the type of animal, its diet, and how the manure is processed or stored. While manures provide essential nutrients for plant growth, they may not meet the specific nutrient needs of certain crops, necessitating additional soil testing and potentially supplementary fertilizers.
