Mulching under ancient olive trees
by Antonio Jordán, University of Seville, Sevilla, Spain
Mulching is a form of conservation tillage consisting of leaving a layer of crop residues or other materials on the soil surface. Mulch helps to preserve high and sustainable yields by increasing the soil organic matter content and therefore improving soil fertility and physical quality. Mulch tilling is also a form of minimum tillage and a cost-efficient alternative for high-yield conservation agricultural practice. Leaving crop residues (straw in the picture) or other substances (plastic films, stones) on the soil surface is a traditional practice for protecting soil from erosion.
In the picture, Lorena (Univ. of Seville) is sitting on a mulched layer below olive trees more than 400 years old in the island of Mallorca (Spain).
