Moreover, AM
fungi have been proposed as a potent biofertilizer in organic
agriculture in China. However, the effects of different soil
management practices on AM symbiosis development, the amount
of GRSP in soil, and soil C and enzymes in citrus orchards remain
largely unknown, although AM associations play a vital role in the
maintenance of agroecosystem sustainability. Accordingly, the aim
of the present study was to evaluate the influences of natural grass
cover, sod culture with white clover (Trifolium repens L.), and clean tillage soil management on AM colonization in citrus roots, AM
fungal propagules in citrus rhizospheres, and GRSP content, and to
relate these measures with soil chemical and biochemical
characteristics in citrus orchards in southeast China
