| Abstract | ||
| A field experiment was conducted at Ismailia Research Station, Agricultural Research Center, Ismailia Governorate, Egypt, during the summer season of 2011 to evaluate the efficacy of organic synthesized fertilizers obtained from tomato and sugar beet thrones on yield and quality of pearl millet (Pennisetumamericanum ) and sorghum (Sorghum vulgare ) forage crops as well as their effects on some soil properties. The micronutrients like iron, zinc, copper, manganese and boron were chelated with organic synthesized fertilizers. Obtained results showed that amino acids synthesized fertilizers (details about these amino acids are found in first part)chelate micronutrients improved the growth and yield of either pearl millet or sorghum and their uptake of macro and micro nutrients when their applied either separately or integrated with NPK fertilization as foliar or soil + foliar application to foliage crops grown in poor sandy loam soil at Ismailiah area. Concerning the effect of synthesized fertilizers on soil properties, the results indicated that organic matter and CEC of soil tended to increase slightly with the use of synthesized fertilizers as compared with unfertilized check, also they improved the soil content of macro and micro elements. The efficiency of organic synthesized fertilizers were improved when their applied in combination with 1/2 unit or one unit of NPK recommended rates. Depending on results of this study, it can be recommended to use these organic synthesized fertilizers which obtained from tomatoes and sugar beet thrones commercially as cheap source of amino acids chelate micronutrients to solve the problem of micro elements in new lands and recycling these wastes and improve soil nutrient conditions. | ||
