The cultivation of Gypsophila is of economic importance for Ecuador, it represents 9% of the exports of flowers, but its monoculture results in the degradation of the soil, probably its physical, chemical and biological properties are affected, for that reason the use of organic amendments could favor your recovery. Thus, the objective of the research was to recover the productive capacity of a soil of Ecuador exploited for eighteen years with Gypsophila monoculture under La Molina conditions, through the application of compost compared to vermicompost of common origin, prepared on the basis of waste of garden prunings and cow dung and alternate with doses of P. Three trials were carried out under greenhouse conditions and in the laboratory, amendments, substrate and foliar content of Gypsophila were characterized. Compost and vermicompost doses were tested in three harvest cycles of Gypsophila, increasing doses of phosphorus in corn and the effect of the amendments with additions of phosphorus in Gypsophila. The vermicompost presented, lower pH, lower salinity, lower concentration of sodium and higher humidity retained, the compost treatment 0.50% in crops 1 and 2 achieved higher height and dry weight of the stem of Gypsophila, while the treatment vermicompost 0.50 % was better in harvest 3, the amendments allowed to reduce the density and variation of pH and increased the OM content of the soil. The soil does not present significant levels of phosphorus adsorption. The dose of P 200 ppm reached the best results of the agronomic variables in corn. When mixing the organic amendments with phosphorus, improved the availability of this nutrient there was an increase in the yield of Gypsophila, the statistical differences did not reach significance, but the best results correspond to the treatments vermicompost 1.5% and compost 1.5% both with P doses of 200 kg / ha
