Abstract
Two field experiments were carried out at Bahr Hadous drain and El-Salam canal locations in Sahl El-Hossinia , El-Sharkia -Governorate, Egypt, for winter seasons of 2014/2015 and 2015/2016, to study the effect of humic acid application on some physical and chemical soil properties and fodder beet (Beta vulgaris L.) productivity and quality in saline soil conditions irrigated with different water sources i.e. [Bahr Hadoos drainage water and Nile water from El-Salam canal mixed with agricultural drainage (1:1)].The obtained results show a noticeable reduction in soil pH and salinity as a result of treating the soil with humic acid compared to control. The effect is more obvious in case of applying humic acid high rate of (2400 ml/400 L water,T4) irrigated with El-Salam canal water than Baher Hados drain water .The soil O.M content and cation exchange capacity values were improved by applying humic acid high rate where soil OM content reached 0.80 and 0.73 % in case of using El-Salam canal and Baher Hados drain water compared with 0.63 and 0.55 % for control treatment, respectively. The highest diameter of dry aggregates was affected by the application of humic acid high rate with El-Salam canal water than Baher Hados drain water .Moreover, the maximum values of total stable aggregates were obtained in case ofhumic acid high rate using El-Salam canal water compared to Baher Hados drain water and control treatments. The data also show that the values of hydraulic conductivity were lowand increased by humic acid application. The highest value of hydraulic conductivity was obtained in case of applying humic acid high rate using El-Salam canal water than Baher Hados drain watercompared to control treatment. Applying humic acid high rate decreased the soil bulk density and increased total soil porosity valuesusingEl-Salam canal water as compared to Baher Hados drain water and control treatments. The maximum values of field capacity and available water were recordedin case of applying humic acid high rate using El-Salam canal than Baher Hados drain water compared to control. The result show an increase in fodder beet yield in all treatments compared to control and was higher in the case of humic acid high rate with El-Salam canal than Baher Hados drain water. Generally, the study recommends using humic acid (2400 ml/400 L water,T4) with El-Salam canal or Baher Hados drain which improves soil chemical and physical properties and thus increases the productivity of saline soil.
