The use of commercial yeast strains is a common practice in winemaking leading to a predictable quality in wine production, avoiding stuck or sluggish fermentations. However, the use of commercial yeasts leads to a consequent reduction in autochthonous microbial diversity. In this study, 1047 isolates from three Spanish appellations of origin were checked for fingerprinting on interdelta polymorphisms and the strain composition and diversity analysed using an extensible open‐source platform for processing and analysis of an in‐house polymorphism database developed for this study. Ancient vineyards managed with organic practices showed intermediate to low levels of strains diversity indicating the existence of stable populations of Saccharomyces cerevisiae strains. A drastic reduction in the number of different S. cerevisiae strains was observed in vineyards with cellars using a selected autochthonous S. cerevisiae strain for winemaking. Contrary, the use of allochthonous commercial strains in wineries did not seem to affect the native S. cerevisiae strain composition and diversity. Significance and Impact of the Study The aim of this study was to compare different viticulture and oenological practices to determine their influence on the composition and diversity of Saccharomyces cerevisiae strains in wine fermentations. The study shows that the use of autochthonous strains of S. cerevisiae as starters for wine fermentation could have an important incidence on S. cerevisiae strains diversity in surrounding vineyards. The use of autochthonous strains of S. cerevisiae reduced the detected number of S. cerevisiae strains, a fact that was not observed when allochthonous commercial strains were used. Furthermore, vineyards managed with organic practices showed intermediate to low levels of S. cerevisiae strain diversity, whereas conventional practices showed higher levels.

“…Soil systems management, such as crop rotation, may alter soil habitat by influencing soil nutrient status, thereby stimulating or hindering microbial activity (Balota et al, 2004; Ashworth et al, 2017c). Like earthworm communities, microbial populations varied spatially and were most affected by long‐term poultry litter applications, although for both locations there was a significant but weak relationship between soil physiochemical and the microbial community composition matrix (RECM P = 0.017, MTES P = 0.03) (Fig.…”

“…Soil was sampled for microbial analyses March 2013 and 2014 at both locations in the upper 0 to 15 cm on all soil amendment and cover crop treatments, but only on selected crop rotations (Table 1). Briefly, per Ashworth et al (2017c), total soil DNA was extracted using the PowerLyzer PowerSoil DNA Isolation Kit and PowerLyzer homogenization instrument (MOBIO Laboratories), according to the manufacturer's directions. DNA extracted was quantified using the Quant‐It PicoGreen double‐stranded DNA quantitation assay and stored at −20°C.…”

“…Poultry litter, a composite mixture of poultry manure and bedding materials, is a source of N and P, and continuous annual applications can affect labile soil N and P, as well as the soil ecology (Ashworth et al, 2017c). Poultry litter has proven to increase fertility and meet crop N requirements (Endale et al, 2004; Tewolde et al, 2010).…”

Crop Rotations and Poultry Litter Affect Dynamic Soil Chemical Properties and Soil Biota Long Term

Dynamic soil chemical interactions with conservation agricultural practices and soil biota are largely unknown. Therefore, this study aims to quantify long‐term (12‐yr) impacts of cover crops, poultry litter, crop rotations, no‐tillage, and their interactions on dynamic soil properties and to determine their relationships with nutrient cycling, crop yield, and soil biodiversity (soil microbial and earthworm communities). Main effects were 13 different cropping sequences of soybean [Glycine max (L.) Merr.], corn (Zea mays L.), and cotton (Gossypium hirsutum L.) at the Research and Education Center at Milan, TN, and eight sequences of corn and soybean at the Middle Tennessee Research and Education Center, Spring Hill, TN. Sequences were repeated in 4‐yr phases from 2002 to 2014. Split‐block cover crop treatments consisted of winter wheat (Triticum aestivum L.), hairy vetch (Vicia villosa Roth), poultry litter, and a fallow control. Soil C and nutrient fluxes were calculated at surface (0–5 cm) and subsurface (5–15 cm) layers during Years 0, 2, 4, 8, and 12. After 12 yr, weighted means (0–15 cm) of soil pH, P, K, Ca, Mg, total N, and C were greater under poultry litter‐amended soils compared with cover crops (P < 0.05). In addition, continuous corn sequences resulted in greater soil K, N, and C concentrations than soybean–soybean–corn–corn rotations (P < 0.05). Poultry litter treatments were positively correlated with greater soil fertility levels, as well as higher crop yield and soil biodiversity. These results underscore linkages between manure additions and cropping sequences, within the nutrient cycling, soil health, and crop production continuum. Core Ideas Bio‐covers illicit greater soil property responses than crop rotations in upper horizons. After 12 yr, cropping rotations affect subsurface physiochemical fluctuations. Soil biodiversity was linked to poultry litter and high‐residue‐producing crops. Poultry litter was the greatest driver for earthworm and microbe community structure. Crop rotation diversity altered soil habitat by influencing nutrient status and residue.

Poultry litter is a nutrient-dense fertilizer, but surface applications lead to nutrient losses to air, soil, and water. Objectives were to evaluate optimum subsurface-applied poultry litter bands from crop seeding distance in a corn (Zea Mays L.)-soybean [Glycine max (L.) Merr.] rotation. Soil amendment treatments included planting 13, 25, and 38 cm from subsurface-banded poultry litter, surface-applied poultry litter, inorganic nitrogen (N), and 0 kg N ha −1 (control) in Year 1, followed by soybean in Year 2 (no new soil amendment applications). Across subsurface treatments, corn grain and silage yields were 45 and 30% greater compared with surface applications, respectively, with inorganic N not differing from 25-and 38-cm bands during grain harvest. In Year 2, subsurface-banded soybean grain yields were 26% greater than with inorganic N. Consequently, subsurface banding poultry litter may be an ecologically and agronomicallyviable replacement for surface litter applications in corn silage and grain systems and inorganic N in corn-soybean rotations.
