Thus, we quantified the embedded phosphorus for the 38 major crops produced in Mexico from 1980 to 2015, which were grouped into forages, fruits and vegetables, cereals, legumes, and cash crops. The total phosphorus extracted was 4.4 × 106 tonnes for an agricultural production of 5,844 × 106 tonnes, which respectively increased by 86% and 145% over 35 years. Food crops, i.e., cereals, fruits and vegetables, and legumes, accounted for 44% of the total phosphorus extracted, forages for 38%, and cash crops for 18%. Forage production exhibited a substantial increase since 1995, becoming the largest phosphorus extractor by 2000. Our estimation of embedded phosphorus is susceptible of utilization in other countries and is a first step to estimate a country's phosphorus balance, which is necessary to understand the magnitude of the anthropogenic alteration of a biogeochemical cycle that is essential for the maintenance of life on earth.},

We determined arbuscular mycorrhizal fungi (AMF) root and soil colonization , and the activity of three P-related eco-enzymes over two consecutive years. We also determined C, N, and P concentrations and ratios in plant biomass, microbial biomass and soil for assessing nutrient homeostasis of soil microbial community and plants. S. airoides invested more carbon in the AMF symbiosis in the drought year in the site more limited by P (Pozas Azules site). Additionally, the specific activity of phosphomonoesterases was higher in this site, suggesting that the microbial community invests more energy to produce this enzyme to release P from organic molecules. In conclusion, our results show evidence of the importance of AMF symbiosis for S. airoides to cope with P and water limitations in a highly oligotrophic ecosystem.},
