Abstract
The present study was conducted in the experimental farm of Agricultural Development System Project in Giza, during the growing seasons 200212003 and 200312004, using humic substances extraction from farmyard manure (HAs) to study their effect on soil nutrient and growth of Ficus benjamina L. and Geranium sanguineum L. plants. The humic acid was extracted with KOH and HN03 and characterized by chemical methods and UV, visible absorption and infrared spectroscopic analysis. The humification index, humification ratio, and humic acid% values were 0.70, 0.42 and 39.3, respectively. The elemental composition of humic acid was as following: C 44 %, N 4.73 %, H 4.21 %, S 1.52%, 045.54% and C:N 9.30. The absorbance decreased as wavelength increases and no absorption found in range of 300-700 nm while a small absorption peak appeared at wavelength near 270 nm. The EJEe ratio of cleared humic acid was 5.11. Sandy and loamy sand soils were treated with HAs (6 g L·1 at pH5) at field capacity, nitrogen, phosphorus, zinc, copper, manganese and iron concentrations increased as compared with untreated soil. The effect was more pronounced in sandy than the loamy sand soil. The foliar application treatments of extracted HAs at pH 5 (2, 4 and 6 ml of HAs 1 00mr1.) with 0.1 N KOH and 0.1 N HN03 from farmyard manure has significant improved the root mass, root length, roots number, leaf area, plant height, number of branches plant" of Ficus benjamina L. and Geranium sanguineum L. and nutrient content of Ficus benjamina.
