We investigated in field experiments whether soil application of a commercial mycorrhizal inoculum (CI) with and without addition of phosphorus (P) fertilizers provided greater maize (Zea mays L.) yields and more soil available P than indigenous fungi alone. A field experiment was established with and without applications of commercial inoculum of arbuscular mycorrhizal fungi (AMF) in combination with three fertilizer rates (NPK = N200P90K160; NK = N200P0K160; and control = N0P0K0). Plant and soil (bulk and rhizosphere soil) samples were collected. Results showed that application of CI, in the NK treatment, resulted in plant growth, grain yield and P uptake similar to that found in treatments that received P fertilizer (NPK). After 40 days, inoculation increased available soil P concentrations, both in the NPK and NK treatments. This indicates that inoculated roots mobilize more P and plants may have uptaken more P from soil. The results suggest that AMF inoculation can be used as a component of integrated nutrient management strategies. |
