This research aims to study the effectiveness of using coffee residues to fertilize the soil in agriculture in Ibri, by answering the following questions:
1. How can coffee residues be used to fertilize the soil?
2. What are the properties of water and soil before and after adding the coffee residue to them? In terms of: (salinity, conductivity, acidity (pH), solubility of oxygen, carbonate ratio?
3. How effective is the use of coffee residues to increase agricultural production?
This research was applied in one of the villages of Ibri (Kawas), to answer the above questions. We relied on the method of scientific research where the corn plant was irrigated with water added to some coffee residue and compared the growth rates with another corn plant watered with normal water. That is by applying the water and soil protocol to measure the conductivity, salinity and acidity properties of the two normal water samples, the water added to the coffee residue, as well as the soil.
