| Abstract |
A field experiment was conducted in sandy soil at El-Ariash Agric. Res. Station in North Sinaa Governorate (latitude, 31o 7' 9.659" N and longitude, 33o 43' 52.539" E) for winter season (2009-2010) to investigate the effect of different organic acids as soil conditioners such as humic acid (HA) and fulvic acid (FA) with or without enrichment with cyanobactaria along with different micronutrients chelated on organic acids on improving soil chemical characteristics, productivity of both barley and faba bean and total content of mineral nutrients. Results indicated that the saturation percent (SP) did not show any obvious trend at both tested soil of crops, moreover, the values of EC and pH in soil at first and second crops have significantly decrease affected by studied treatments as compared to control.
Application of humic acid enriched with cyanobacteria and foliar spray with micronutrients chelated on fulvic acid either the previously treatments individually or in combination, significantly superior for decreased values of EC in soils and increased values of both organic matter and available macronutrients in the soil. On the other hand, the application of fulvic acid without cyanobacteria and foliar spray with micronutrients chelated on fulvic acid either the previous treatments were applied individually or in combination, had decreased pH values of the soil as compared to control and other treatments.
Data also showed that the highest significant yield components of barley and faba bean crops as well as their total contents of macro and micro nutrients were reported for application of humic acid enriched with cyanobacteria combined with foliar spray with fulvic acid and micronutrients as compared to other treatments.
In addition, the results showed that protein and proline contents for either grains of barley or seeds of faba bean had increased due to the application of tested treatments as compared to control. ِAlso, data indicated that the application of the tested treatments increased the proline concentration and decreased the sodium concentration in grains of barley and seeds of faba bean, these effects dependent on forms of organic acids.
In conclusion, the application of organic acids enriched with cyanobacteria and foliar spray of micronutrients chelated on organic acid may be helpful to improve the soil properties and reflected that on yield components along with uptake of nutrients
