Soil microbial and nutrient dynamics influenced by irrigation-induced salinity and sewage sludge incorporation in sandy - loam textured soil

Abstract: biomass carbon, enzyme activity INTRODUCTION The rapidly increasing human population and urbanization have led to the production of domestic and industrial waste in large amounts (Sharma and Dhaliwal, 2019). Sewage sludge is a semi-solid byproduct which is obtained from wastewater treatment plants and treated as waste in developing countries like India where it remains deposited near municipal solid waste treatment plants. It poses a great environmental threat when no management strategy is adopted for proper sludge disposal. Despite the widespread assumption that sewage sludge (SS) is a problem, its management as a valuable organic resource has become essential for sustainability. Moreover, SS is a potential source of nutrients that may be applied to agricultural lands (Bourioug et al., 2017). It may be used as an organic fertilizer that produces a favourable crop yield and it may even replace mineral fertilizers but only when it does not pose any risk to soil quality and human health (Ahmed et al., 2010). Its excessive use can also cause heavy metal toxicity in soils and plants (McGrath et al., 2000). Sewage sludge is relatively inexpensive in comparison to mineral fertilizers and has a higher amount of organic matter and plant nutrients, particularly nitrogen, phosphorus, potassium, calcium, and micronutrients (Jezierska-Tys and Frąc, 2009). It improves the physical, chemical, and biological properties of the soil (Aranyos et al., 2016; Meena et al., 2016). © 2020 Institute of Agrophysics, Polish Academy of Sciences

Effect of Potassium and Boron Fertilization on Growth, Forage Yield and Quality of Berseem Trifolium alexandrinum L

Abstract: The field experiment was conducted during rabi season of 2017-18 at the Forage Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar with the objective to study the effect of potassium and boron fertilization on growth, forage yield and quality of berseem. Treatment combinations comprised of four potassium levels i.e. 0, 20, 40 and 60 kg K2O ha-1 and four levels of boron i.e. 0, 2, 4 kg B ha-1, and 0.2% B spray at flowering initiation and at 50% flowering. The experiment was laid out in split plot design and replicated thrice. Growth characters improved with the application of potassium and boron. Maximum green fodder (444.24 q ha-1) and dry matter yields (55.32 q ha-1) were obtained when berseem was fertilized with 40 kg K2O ha-1. Crude protein yield was highest with 60 kg K2O ha-1 (10.29 q ha-1) and digestible dry matter at 40 kg K2O ha-1 (37.19 q ha-1). Incremental dose of applied boron resulted in a significant improvement in green fodder and dry matter yields upto 2 kg B ha-1. Significant interaction effects of potassium and boron on total green fodder and total dry matter yields indicated better effects with the combination of 40 kg K2O ha-1 and 2 kg B ha-1.

Foliar enrichment of potassium and boron overcomes salinity barriers to improve growth and yield potential of cotton (Gossypium hirsutum L.)

Abstract: Foliar application of essential minerals is considered as an economical approach to enhance growth and productivity of crop plants. This study aims to assess the individual and combined effects of ...

An assessment of domestic sewage sludge in pearl millet-wheat system under saline irrigation

Abstract: The present two-year experiment (2017-19) evaluated the impact of domestic sewage sludge (SS) on yield parameters and soil nutrient status under the pearl millet-wheat system using saline irrigation. The field study consisted of three irrigation treatments [canal water (0.35 dS/m); saline water (8 and 10 dS/m)], and five fertilizer treatments [control, SS (5 t/ha), SS (5 t/ha)+50% recommended dose of fertilizers (RDF), SS (5 t/ha)+75% RDF and 100% RDF]. The results revealed a significant reduction in the biological yield and yield attributes, and protein content of both crops with increasing salinity levels of irrigation water during both the years. However, all these parameters recorded significantly highest values under 100% RDF which was statistically at par with SS (5 t/ha) + 75% RDF treatment. The soil available sulphur (S) was significantly increased with 8 and 10 dS/m EC of saline water over canal water (0.35 dS/m) irrigation. But, SS (5 t/ha) + 75% RDF obtained 36.7 and 22.3% higher available S over control and 100% RDF, respectively. No significant effects were made in DTPA-extractable micronutrients (Fe, Mn, and Cu) with saline irrigation except Zn, which was reduced under saline environment. SS added treatments obtained higher micronutrient concentration over control. Hence, SS incorporation has proven useful in sustainable crop production and improved micronutrient availability in the soil.
