Ammi majus species have ornamental value; however, the main object of study is the content of coumarins and furanocoumarins, substances used as base products for skin conditions. The aim of this study was to determine the performance of micronutrients with the application of compost. The experiment was conducted in 2013 in Texcoco, Mexico. The treatments consisted of mixing soil: compost 1:1 soil alone; two mixtures were added 20 and 30% "perlite" and a third 100 g of NPK fertilizer generating five treatments. Plants were harvested at five months of age; dried at 71 °C, weighed and ground for analysis of Fe, Cu, Mn and Zn. PH, electrical conductivity, organic matter and cation exchange capacity of the substrates were analysed. Compost had no effect on dry matter production, but significantly affected the pH, EC and CEC of the substrates. Mixtures with "perlite" and mixing with fertilizer produced the highest yields; in these, the pH went up and CE went down, both significantly. Only Mn showed signif icant differences, absorption increased with compost and with decreasing pH induced fertilizer. It is concluded that the addition of compost increased yield of Ammi majus, due to changes induced in the substrate and not necessarily the traditional nutrients.
