Responses of soil microbial community structure and enzymatic activities to long-term application of mineral fertilizer and beef manure
The intensive use of mineral fertilizers to achieve high crop yield has led to soil degradation and poor soil health. Thus, manure application as an alternative to mineral fertilizers can be an effective fertilization strategy to sustain soil health and biodiversity. This study aims to assess the im...

The intensive use of mineral fertilizers to achieve high crop yield has led to soil degradation and poor soil health. Thus, manure application as an alternative to mineral fertilizers can be an effective fertilization strategy to sustain soil health and biodiversity. This study aims to assess the impacts of long-term manure and mineral fertilizers on key soil biochemical and biological indicators. The study was conducted on a 16-year long-term experimental site with six different manure and fertilizer treatments that included no amendments (CK), recommended mineral fertilizer (MF), higher rate of mineral fertilizer (HF), manure application based on the phosphorus requirement (LM), manure application based on the nitrogen requirement (MM), and double the rate of MM treatment (HM).
