Applications of Actosol® Humic Acid Products in Egypt.

Egyptian soils have become deficient in soil organic matter and its active humic components due to erosion, excessive cultivation, and inhibited sedimentation by the Nile River following construction of the High Dam of Aswan.  Further, population pressure is compelling Egyptian farmers to cultivate inherently poor, sandy and calcareous soils far from the Nile Delta.  Therefore, vertical expansion or improvement of soil fertility to meet the Egyptian need for agricultural development is necessary.  This research paper will present results of several field studies conducted with our Actosol® humic acid products at several farms and government experimental stations with different soil types at West Tahreer, Kafr El Sheik, and Noubaria in Egypt.  These studies were conducted to evaluate the effects of humic acid products on growth and yield of rice, clover, and wheat as well as to evaluate their role in enhancing the salt tolerance of deciduous fruit seedlings, including apricot and peach.  Humic acid product was applied at 2 to 3 gallons / acre to the soil or as foliar application.  Results indicate that product addition enhanced seedling emergence, plant growth and color in wheat and clover.  In addition, the use of Actosol® humic acid mitigated the harmful effect of salinity on peach and apricot seedlings.  It increased their leaf area, dry matter, and root systems and decreased Cl and Na contents of their leaves.
