Soil salinization has become a major challenge that severely threatens crop growth and influences the productivity of agriculture. It is urgent to develop effective management measures improve saline–alkali soil. Thus, in this study, soil properties, microbial communities, function under desulfurization gypsum (DE), amendment (SA), farm manure (FA), co-application gypsum, amendment, (TA) field experiment were examined by high-throughput sequencing. The results showed application modified materials an approach improving soil, especially TA treatment significantly increased content available phosphorus (AP), potassium (AK), organic matter (SOM), alkaline hydrolysis nitrogen (AHN) decreased pH, bulk density (BD), electrical conductivity (EC). resulted notable enhancement fungal diversity altered composition structure community. Conversely, effect on bacterial community was comparatively minor, with changes limited Regarding composition, Ascomycota, Mortierellomycota, Basidiomycota emerged as dominant phyla across all treatments. At each taxonomic level, exhibited significant variations response different materials, resulting divergent quality. led decrease Mortierellomycota increase potentially enhancing ability decompose facilitate nutrient cycling. Additionally, sensitivity biomarkers surpassed impact communities primarily stemmed from alterations EC, AP, AK, SOM. FUNGuild analysis indicated saprotroph trophic mode group component, notably symbiotroph group. PICRUSt revealed metabolism most prevalent functional module observed at pathway level 1. Overall, EC levels, more community, but it did not dramatically change Our study provides new insights into increasing nutrients altering functions better for Hetao Plain.

Soil type and integrated nitrogen nutrient-rice straw residue management techniques affect soil microbes, enzyme activities and yield of wheat crop

Heliyon, Journal Year: 2023, Volume and Issue: 9(6), P. e16645 - e16645

Published: June 1, 2023

Sporadic burning of rice straw and the particulate air pollution caused consequently have created a pressing need for identification practical environmentally sound in situ residue management methods. However, agronomic interventions associated with agri-inputs particularly type nitrogen fertilizer source must be worked out these interventions. In two-year field study performed at two different locations representing sandy loam clay soil types, zero tillage application nitrophosphate (applied as basal dose through drilling) combination urea 1st irrigation + 3 foliar sprays weekly interval) significantly enhanced grain yield wheat. The microbial viable cell counts dehydrogenase urease enzyme activities were also recorded to highest this treatment indicating occurrence higher living population. × response variable Principle component analysis (PCA) biplot depicted relative variation among treatments/Nitrogen sub-treatments variables. A organic content components was recognized Fourier transform infra-red spectroscopy (FT-IRS) studies. Irrespective types under study, FT-IR spectra exhibited presence aromatic carbon functional groups incorporated treatments compared no incorporation treatment.

Effect of Nano-Zinc Oxide, Rice Straw Compost, and Gypsum on Wheat (Triticum aestivum L.) Yield and Soil Quality in Saline–Sodic Soil

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(17), P. 1450 - 1450

Published: Sept. 5, 2024

The salinity and alkalinity of soils are two fundamental factors that limit plant growth productivity. For reason, a field study conducted at Sakha Agric. Res. Station in Egypt during the 2022–2023 winter season aimed to assess impact gypsum (G), compost (C), zinc foliar application images, traditional (Z1 as ZnSO4) nanoform (Z2 N-ZnO), on alleviating saline–sodic conditions soil its wheat results showed combination gypsum, compost, N-ZnO spray (G + C Z2) decreased electrical conductivity (EC), sodium adsorption ratio (SAR), exchangeable percentage (ESP) by 14.81%, 40.60%, 35.10%, respectively. Additionally, compared control, G Z2 treatment improved nutrient content uptake well superior biomass parameters, such highest grain yield (7.07 Mg ha−1), height (98.0 cm), 1000-grain weight (57.03 g), straw (9.93 ha−1). Interestingly, was more effective than ZnSO4 promoting Principal component analysis highlighted negative correlation between increased EC SAR, whereas organic matter (OM), infiltration rate (IR), were found be positively correlated. Furthermore, employing k-nearest neighbors technique, it predicted would rise 7.25 t ha−1 under certain (5.54 dS m−1), ESP (10.02%), OM (1.41%), bulk density (1.30 g cm−3), (1.15 cm h−1), SAR (7.80%). These demonstrate how adding can improve quality, increase yield, uptake, all which support sustainable agriculture.
