The use of sheep manure as a fertilizer in the cultivation of olive trees is a traditional practice that has proven to be highly beneficial for soil health and tree productivity. This method aligns perfectly with the principles we follow at MARE OLEUM of organic farming, which seeks to reduce the use of synthetic chemicals and promote sustainable and environmentally friendly practices.
Fertilizer composition and benefits
Sheep manure is rich in essential nutrients vital for the healthy growth of olive trees. It contains nitrogen (N), phosphorus (P), potassium (K) and micronutrients such as calcium, magnesium and zinc.
These nutrients play a crucial role in various plant functions. Nitrogen is essential for vegetative growth and leaf development; phosphorus is important for root formation and flowering; and potassium improves tree resistance to disease and adverse conditions and is essential during fruit formation.
Fertilizer application
Fresh manure should be composted prior to application to avoid phytotoxicity and odor problems. Composting allows organic matter to decompose and nutrients to stabilize, converting them into forms that plants can easily absorb.
Once composted, the sheep manure is spread evenly around the base of the olive trees. The amount to be applied may vary according to the specific needs of the soil and trees.
Fertilizer benefits
Sheep manure increases the organic matter content in the soil, which improves its structure. A soil with good structure has better water holding capacity and aeration, which is crucial for healthy root development.
A recent study conducted by the Zaidín Experimental Station in Granada (EEZ-CSIC) and the Institute of Sustainable Agriculture in Cordoba (IAS-CSIC) has provided an in-depth insight into the benefits of sheep manure on olive trees. Using advanced massive DNA sequencing techniques, scientists characterized 1,200 bacterial species and 250 fungal species in olive soil.
The study, published in the Computational and Structural Biotechnology Journal, demonstrated significant improvements in the symbiotic relationship between plants, bacteria and fungi after the application of sheep manure as compost on the soil, benefiting olive trees as these microorganisms protect them from pathogens and increase available nutrients.
Environmental impact and sustainability
The use of sheep manure not only benefits the olive trees and the soil, but also has a positive impact on the environment. By using sheep manure, livestock waste is recycled, reducing the need for landfills and reducing greenhouse gas emissions associated with the decomposition of organic waste in uncontrolled environments.
In addition, the reduction in the use of chemical fertilizers reduces soil and water pollution, protecting the surrounding ecosystems. The practice of manuring also promotes soil biodiversity, creating a healthier and more balanced environment.
