Ammonium humate (AH) is a substance that applied in agriculture as a fertilizer and soil conditioner. It is created when humic acid, reacts with ammonium hydroxide. So, it is considered a useful tool because it has various advantages for plant growth and development. A field trial was conducted on sandy soil at the Ismailia Agriculture Research Station farm in Ismailia Governorate, Egypt, during the winter season of 2021–2022 to study the influence of three forms of 3% ammonium humate (AH₁, AH₂, and AH₃) and two methods of application (foliar on the plant (M₁) and spraying on the soil (M₂)) on the growth of cultivated crops (wheat, faba beans, and lupine) and some soil properties. Obtained results indicated that adding different forms of AH significantly increased crop productivity, macronutrient total content, and protein percent. The AH₂ form was superior in yield, and the soil application was positive compared to foliar application on the plant. The interaction between AH form and method of application indicated that AH₂M₂ treatment was the best for all tested crop productivity. Macronutrient availability increased with all experiment treatments, and the highest available N values were with the AH₁M₂ treatment. Organic matter content in the soil was highest when different ammonium humate forms were applied to the soil compared to foliar application.
