| Abstract | ||
| Sandy soils are widespread across the globe and are essential for bridging the food gap, promoting sustainable agriculture, and increasing the agricultural income of the community. Sandy soils are considered light in texture and low in fertility. So, fertility must be increased, and its chemical and physical properties must be improved by applying organic and inorganic amendments for enhanced soil properties. To achieve this goal, a field experiment was conducted at the Ismailia Agricultural Research Station in Ismailia Governorate, Egypt. The experiment evaluated the impact of different levels of both humic acid (HA) in the form of potassium humate powder and silicon (Si) in the form of potassium silicate and their effect on wheat and sesame crop productivity. The chemical properties of the soil were taken into consideration. The results showed that using HA as soil application and Si as foliar application at varying levels significantly increased the yield of wheat and sesame crops compared to the control treatment. Also, a similar trend was observed with the nutritional total content (P, K, and Si) in the straws, grains, and/or seeds of both tested crops. Moreover, the treatments improved soil chemical properties (pH, EC, and OM%) and increased the availability of phosphorus, potassium, and silicon after the wheat-sesame crops were harvested. In conclusion, the soil application of HA and foliar sprays with silicon significantly boosts the productivity of both wheat and sesame crops. Along with improved fertility in light-textured soil, this approach promotes agricultural sustainability and helps protect sandy soils from degradation. | ||
