“…This renewable resource is poorly recovered and mostly abandoned in fields, which can cause insect and disease infestation, or other environmental issues like accidental fires [19]. In recent studies, date palm residues co-composted with sheep manure showed promise for increasing the soil fertility and corn yields in an arid agroecosystem [20]. Nitrogen and phosphorus uptake by silage corn was also enhanced over two growing seasons following a single application, suggesting a long-lasting effect of this compost.…”

Generally, soils of arid and semi-arid regions have low water retention properties due to high sand and low organic carbon contents. This study aimed at quantifying the effect of date palm-based organic amendments (OAs) on the water retention properties of two soils (sandy loam and silty loam), as well as the influence of sand supplementation (0.5–2 mm) on the magnitude of the effect of OAs. Different grain size distributions were obtained by adding sand to natural soils. For this purpose, sand was added to the two soils (1/3 and 2/3) and different soil-OA combinations were tested at a dose of 3% by mass: compost alone, biochar alone and a mixture of biochar and compost (50:50 in mass), in addition to unamended control soils. Soil water contents were measured at nine matric potentials ranging from the saturation to the permanent wilting point. Biochar was more efficient than compost at improving soil water retention. The effect of organic amendments on water retention increased with sand content. In most cases, soil water content values were significantly higher for biochar-amended soils than for unamended or compost-amended soils. The weakness of the effect of compost addition (if alone) was probably due to its properties and notably its high mineral content and electrical conductivity. Soil sand supplementation led to higher differences between the OA-amended soils and unamended soils. Changes in available water capacity reached +26% and +80% in a sandy loamy soil enriched with 2/3 sand and amended with compost and with biochar, respectively, compared to the unamended soil. These results show that sand content (and more generally, soil texture) influences the effect of OA application. Thus, the application of biochar from date palm residues in soil seems to be an effective solution to improve the water retention properties of coarse textured soils and contribute to optimizing the use of water resources in irrigated areas.

Phosphorus Sources and Sheep Manure Fertilization for Soil Properties Enhancement and Sugar Beet Yield

et al. 2023

Inorganic fertilizers abundant used cause hazardous environmental effects and unsafe food. Contrarily, organic fertilizers are usually utilized as soil amendments and they boost crop yield quantity and quality. A field experiment was carried out to study the effect of some phosphorus (P) sources, such as rock phosphate (RP), superphosphate (SP), and sheep manure (SM), on some soil chemical properties, growth and yield in sugar beet plants. The field experiment was arranged in a completely randomized block design with three replicates for two growing seasons (2020/21and 2021/22). Results showed significant increases in yield and physiological parameters in all treatments. Co-applying of RP with SP caused a significant increase in the SOM, N, P, and K by 70.45, 31.52, 128.35, and 24.85% respectively compared to T1. All applications to the soil significantly increased the fresh weights of sugar beet roots were significantly increased by 24.71, 17.92 and 25.72% for T2, T3, and T4 respectively over the control. Also co-application of SM and SP (T3) lead to the highest sucrose content which increased by 5.09% than the control. Therefore, we concluded that integrated fertilizer management improves soil properties and yield so these results can be used to employ to reduce the detrimental consequences of using chemical fertilizers.

Dry leaves of date palms (DPs) are by-products of date cultivation that are often mismanaged in oasis agroecosystems. Ideally, they should be upcycled in a circular agriculture model before producing and exporting high-value products. Compost inputs enhance soil organic matter and conserve soil. This study investigated composting of four mixtures based on farming system requirements and the availability of organic resources. The DPs were used alone or combined with sheep manure and rock phosphate. We experimented with farm-scale windrow composting to improve understanding and support decision-making. The results showed that temperature increased rapidly to 70 °C at the beginning of composting in the mixtures with manure. Organic matter content decreased by 40% in all windrows during composting, which indicated organic matter mineralisation and loss of volatile solids. Composting DP with or without sheep manure for 136 days with two turnings conserved nitrogen and increased the nitrogen content of compost. Mixing DP with sheep manure and rock phosphate increased the final total phosphorus content of compost to 0.52% (dry matter basis). Our results highlight that composting DP is a feasible alternative to improve circularity in oasis agroecosystems, by increasing organic matter content and fertiliser value, thus paving the way for sustainable production of high-value products from DP.
