Abstract
The forms in which iron occurs in the soil solution are dependent on the pH, so that in basic vine–growing soils, the predominant form is the ferric one, which is barely soluble. In this soil types, it is common that appears the typical symptom of iron deficiency (ferric chlorosis). However, it is common to find other important nutritional restrictions for viticulture (mainly at the level of phosphorus and certain micronutrients). In the present work, the results obtained from the incorporation of a mixture of leonardite and heptahydrate ferrous sulfate, in a calcareous vineyard soil, are showed (at the level of soil, petioles and must). The promising data obtained (mainly, at the soil level), linked to its lower cost than traditional treatments such as chelates, and its environmentally friendly nature, make interesting further studies in this alternative as an adequate soil amendment for grapevine cultivated on calcareous soils.
