Effect of integration of poultry manure and vinasse on the abundance and diversity of soil fauna, soil fertility index, and barley (Hordeum aestivum L.) growth in calcareous soils

Abstract

Background: In Egypt, calcareous soils represent a large part of desert soils suffering from a shortage of nutrients and organic matter, affecting production and biological diversity in agroecosystems. Organic wastes, negatively affect the environment, recycling it as a promising technology in different farming systems, and its impact on crop productivity and soil fauna is largely unknown. In this study, the effects of integrating poultry manure (PM) alone or combined with vinasse (V) at rates of 4.2 g kg− 1 and 6.3 g kg− 1 in pots, on improving soil fauna diversity, soil fertility, soil consistency and yield of barley (Hordeum aestivum L.) grown in a calcareous soil were investigated. Results: The results showed that the addition of PM alone or combined with V at different rates led to a significant increase in the microbial biomass carbon (MBC), organic matter (OM), NPK soil availability and yield of barley. The addition of 6.3 g PM and 4.2 g V kg− 1 soil have the best results in OM with 65.0% compared to control, and V contributes more than 16% of them. Prostigmata and Collembola were the dominant groups and accounted for 43.3% and 50.0% in the PM1 and 50.0% and 20.0% in the PM2 of the total individuals, respectively. Shannon and Evenness indices increased significantly with the soil amended by PM alone or combined with V. Soil fauna plays a key role in soil consistency because of a significant relationship between soil fauna and soil OM, MBC and soil fertility index. The addition of 6.3 g PM and 4.2 g V kg− 1 soil gave the best results in grain yield by 76.90% compared to the control. Conclusion: In conclusion, the interaction between PM and V can be used as a promising organic amendments to increase barley yield and improve efficiency of a recycled PM and V on soil fauna and soil fertility of calcareous soil.

Phosphogypsum and poultry manure enhance diversity of soil fauna, soil fertility, and barley (Hordeum aestivum L.) grown in calcareous soils

“…In this study, the total number of soil fauna, Shannon and evenness indices increased significantly when the soil was treated with PM alone or in combination with PG. Similarly, Seleem et al 3 found that the soil fauna populations, Shannon, and evenness indices increased significantly in calcareous soil amended by PM alone or combined with vinasse. This result may be due to the high OM content of the PM.…”

Harnessing the potential of sugarcane-based liquid byproducts—molasses and spentwash (vinasse) for enhanced soil health and environmental quality. A systematic review

“…These byproducts play a crucial role in enhancing soil fertility and promoting sustainable agricultural practices. Notably, vinasse application has shown significant increases in soil fauna and microbial biomass compared to the use of chemical fertilizers (Behzadipour and Sadrekarimi, 2021;Chuppa-Tostain et al, 2018;Seleem et al, 2022). The rich organic content of vinasse provides an ideal environment for soil organisms, leading to improved soil health and nutrient cycling.…”

“…Goswami et al (2023) suggested that the abundant nutrients in molasses and vinasse could directly support plant growth, even without relying on nutrient recycling by microorganisms in the soil. Additionally, co-application of vinasse and poultry manure significantly increased potassium, phosphorus, and nitrogen compared to chemical fertilizers (Seleem et al, 2022). Vinasse also promotes the decomposition of organic matter in the soil, releasing nutrients previously locked up in plant residues or other organic materials (Suleiman et al, 2018;Zhu et al, 2020).…”

“…Vinasse alone contributes a substantial amount of available nutrients, with Cui et al (2021) highlighting its contribution to about 2.3% of the total nitrogen biomass reservoir in China. Coapplying vinasse with poultry manure has shown notable improvements in plant nutrient availability compared to chemical fertilizers, with increases in potassium, phosphorus, and nitrogen (Seleem et al, 2022). Moreover, vinasse serves as a sustainable and enduring source of nutrients in agriculture, potentially reducing the need for inorganic fertilizers in crop production (See Table 3).…”

“…When used alongside inorganic fertilizers, they can mitigate negative impacts associated with synthetic chemicals and optimize agronomic use efficiency (Kumar and Chopra, 2014;Eissa, 2017;Sadiq et al, 2021;Raza et al, 2022). Their varied nutrient profile supports a more balanced and comprehensive nutrient supply to crops, enhancing growth and development (Seleem et al, 2022). However, improper handling of these byproducts may lead to environmental pollution, emphasizing the need for their careful incorporation into the agricultural cycle to ensure agronomic utilization while safeguarding the environment (Dhote et al, 2021).…”
