Description
An experiment concerning the sainfoin pasture fertilization in the "garrigue" (humid mediterranean climate and poor soil with limestone in the South of France) is presented. The aim is to find out if the spreading of cheap micronutrients (powdered pozzolana), with and without macronutrients increases the dry matter production and changes its chemical composition. The main results show that the production is multiplied by about 1.5 with 100 kg/ha/year of each macronutrient and 5000 kg/ha of pozzolana ; this increase varies in relation to species. Most of micronutrients have an effect on the specific chemical composition, according to treatments. Probably, toxicity phenomena appear with 10 000 kg/ha of pozzolana. Questions concerning quantities, times and periodicities of fertilization, specially of pozzolana spreadings, have to be resolved.
