Experimental evaluation of the potential of arbuscular mycorrhiza to modify nutrient leaching in three arable soils located on one slope

Popis výsledku v původním jazyce

The objective of our study was to evaluate the potential of arbuscular mycorrhiza to modify nitrogen and phosphorus cycling including nitrate and phosphate leaching in arable soils. Phosphate and nitrate leaching varied among the three soils according to phosphorus availability and plant growth, both being highest in the soil with the highest sand and phosphorus contents. Nitrate leaching was significantly increased by the soils' native microbial communities, which induced higher net nitrification rates as compared to the treatments inoculated with the pot-cultured microbial communities. Mycorrhiza was formed in all three soils after AMF inoculation, with low to intermediate root colonization levels. However, it had no effect on plant growth or nutrient uptake in any of the three soils, which was consistent with a significant nitrogen deficiency of the maize plants. The absence of mycorrhizal effects on nitrate and phosphate leaching is discussed within this context, and the potential of arbuscular mycorrhiza to reduce nutrient leaching from arable soils is concluded low.
