It is important to increase our understanding of AM fungal and maize genotype interactions, the impact of N and P fertilization and water condition on the symbiosis, and on the physiology and nutritional status of maize plants. In two greenhouse experiments AM inoculated plants exhibited root colonization values around 70% which was confirmed by the presence of the AM lipid biomarker (C16:1cis11). Nitrogen fertilization increased AM root colonization, but only compared to unfertilized plants. Root colonization and biomarker concentration in root and soil were similar among inoculated maize genotypes across conventional and drought tolerant hybrids. Mycorrhizal inoculation had a positive …

Post-2000 efforts to protect China’s grassland areas are distinct from earlier efforts in that funding for the most recent round of policies and programs is commensurate with the task. Among the most controversial of the current policies is the provision of an annual subsidy ranging from 2 yuan to 20 yuan/mu (1/15 hectare) to herders to not graze livestock contracted by their families for periods from 3-10 years. Many other recent policies, such as fencing programs and hunting and burning bans to protect keystone species are also controversial. Ideally, the policies are intended to protect grassland ecological systems while assuring …
