“…Both meta‐analyses demonstrated that manure amendments, especially cattle manure, were beneficial in helping microbial communities recover from long‐term use of IF. Soil protein concentrations are also influenced by livestock manure applications (Halder et al., 2021; Zhang et al., 2014), and in the present study, ACE was significantly increased by up to 104% and it was highly correlated ( r = .73–.96) with all other biological and chemical indicators. In semiarid soils under annual crops in California, ACE was found to be highly correlated with total N, particulate organic N, soluble protein, and POXC, but it was not found to be a good predictor of N mineralization potential in soil with low total N (Geisseler et al., 2019).…”

Dairy manure fertilization is an important practice to return nutrients to agricultural soils, but there is limited knowledge regarding the effect of manure on soil health metrics in semiarid irrigated row crops. The objective of this research was to determine how long-term dairy manure application affects biological and chemical indicators of soil health in a field experiment in southern Idaho. The treatments were no fertilizer, inorganic fertilizer (IF), and dairy manure applied annually or biennially at rates of 17, 35, and 52 Mg ha -1 on a dry weight basis. Spring soil samples were collected 7 yr after project initiation at depths of 0-15 cm and 15-30 cm and analyzed with soil health metrics that are commonly used to quantify organic matter pools and biological nutrient cycling via enzyme activities and N transformation rates. Soil organic C increased with increasing application rate and more than doubled after 7 yr of annual manure at the highest application rate. In general, C and N pools, enzyme activities, and N transformation rates were greater at 0-15 cm than deeper in the soil profile. Compared with IF, annual and biennial manure treatments had a significant effect on most indicators at both soil depths, which increased with increasing manure application rate. Because of the strong response of the indicators to dairy manure, all were found to be positively and significantly correlated with each other, suggesting that only a small subset of the metrics tested could potentially be used to evaluate the influence of manure on soil health in the region.

“…The majority of published studies verified that biochemical features and carbon functional groups of the added residues influenced residue degradation rates (Sarker et al, 2018). Our last publication pointed out that higher soluble sugar but lower cellulose and lignin contents in organic residues were the main reasons for faster residue decomposition, furthermore the alkyl and carbonyl C were positively correlated but O-alkyl C and di-O-alkyl C were negatively correlated with residue decomposition (Halder et al, 2021). In addition to the inherent features of the added residues, the residue-derived CO 2 was significantly inversely related to the aggregate turnover time in the two investigated soils herein (P < 0.01, Fig.…”

“…According to existing knowledge, primary particles and fine-silt-sized aggregates are bound into microaggregates by microbially-derived polysaccharides which are influenced by residue features (Puttaso et al, 2013, Almagro et al, 2021, while microaggregates along with silt-sized aggregates and primary particles are bound into macroaggregates by temporary binding agents (Chung et al, 2008;Jastrow et al, 2007;Verchot et al, 2011). Compared to decomposed maize, vetch contains abundant soluble sugars, which are easily metabolized by the microbial community (Paterson et al, 2011) and positively related to the formation of macroaggregates (Halder et al, 2022), while maize contains more cellulose and hemicellulose, which are less susceptible to microbial decomposition and therefore more persistent (Abiven et al, 2008;Halder et al, 2021).…”

“…For instance, residues that are relatively poor in quality and have a low decomposability (e.g., high C:N ratio, high lignin content) can persist longer in soil and may therefore have a greater potential to improve soil aggregation (Blanco‐Canqui & Lal, 2004). Others have shown that cellulose and soluble sugars in plant residues are important ingredients of soil aggregation (Halder et al., 2021; Tobiašová 2011). Furthermore, plant residue characteristics affect the degree of bacterial versus fungal processing of plant residues, which could further influence soil aggregation (Helfrich et al., 2008).…”

Background Soil aggregation and organic carbon (OC) content are important indicators of soil quality that can be improved with plant residue amendments. The extent of the effects of plant residue amendments on soil aggregation and OC content across different plant residue and soil types is not fully understood. Aim In this meta‐analysis, we evaluated the effects of plant residue amendments on soil aggregation and OC content for different plant residues (fresh, charred) and soil types varying in clay content, initial OC content, and pH. Methods Our meta‐analysis included 50 published studies (total of 299 paired observations). We estimated the response ratios of mean weight diameter (MWD) and separate aggregate size classes, total soil OC (TSC), and aggregate‐associated OC. We also considered the effect of experimental factors (study duration, residue type, residue amount, initial soil OC, clay content, and pH). Results The benefit of plant residue amendment on soil aggregation was larger in soils with initially low OC content and neutral pH. Initial soil OC content and pH were more important than soil clay content for OC storage in soil aggregates. Both fresh and charred plant residue amendments were effective in forming aggregates, whereas charred residues were more effective in increasing TSC. We found only a weak positive relationship between the response ratio of TSC and MWD indicating that other factors besides soil aggregation contributed to the increase in soil C storage. Conclusions While plant residue amendments can enhance soil aggregation and TSC, these effects are likely governed by the type of plant residue and soil properties such as the initial soil pH and OC content.
