- Abstract:
- ... Biological soil crusts (biocrusts) recently discovered in agroecosystems have the potential to enrich soil moisture and nitrogen (N) concentrations and structure the subsurface microbiome. In citrus agroecosystems, year-round N availability is vital for production, with vegetative flushes in the spring and fall and fruit development in the fall and winter. Due to the N demand and natural formation ...

- Abstract:
- ... Some producers in the inland Pacific Northwest (PNW) are interested in diversifying the traditional 2‐yr sequence of winter wheat (Triticum aestivum L.) (WW)–summer fallow (SF) with oilseed crops to capture break crop effects. The objective of this study was to compare production costs and economic returns of 2‐yr sequences with those of intensified 3‐yr sequences at a low‐precipitation (<300 mm) ...

- Abstract:
- ... Zymoseptoria tritici is the causal agent of Septoria tritici blotch (STB), a disease of wheat (Triticum aestivum) that results in significant yield loss worldwide. Z. tritici’s life cycle, reproductive system, effective population size, and gene flow put it at high likelihood of developing fungicide resistance. Succinate dehydrogenase inhibitor (SDHI) fungicides (FRAC code 7) were not widely used ...

- Abstract:

The objective of this study was to compare crop yield, water use efficiency, precipitation capture, and soil water storage between conventional-tillage SF and reduced tillage fallow (RTF) and among different 2-yr ...

This study aimed to evaluate the effects of tillage intensity (minimum vs. conventional) on the soil chemical and microbial properties of a winter wheat (Triticum aestivum L.)–fallow rotation in the low‐precipitation zone of the Pacific Northwest. Soils collected for 2 yr at two depths ...

- Abstract:
- ... Abandoned mine lands present persistent environmental challenges to ecosystems and economies; reclamation is an important step for overcoming these challenges. Phytostabilization is an elegant and cost-effective reclamation strategy, however, establishing plants on severely degraded soils is problematic, often requiring soil amendments. We evaluated whether amendment mixtures composed of lime, bio ...

- Abstract:
- ... Core Ideas Soil attributes can be improved by intensifying crop rotations in combination with reduced tillage. There was weak evidence that intensifying wheat systems with oilseed crops improves aggregate stability. Reduced tillage produces fewer small class size aggregates that impede infiltration. Improving soil aggregation in the semiarid inland Pacific Northwest (PNW) cropping region can impro ...

- Abstract:
- ... Soils under continuous no-till (NT) often produce stratified soil acidification due to fertilizer placement and subsequent lack of mixing. Because aluminum (Al) becomes more bioavailable with lower soil pH, Al toxicity is an emerging problem in many soils throughout the Palouse region in the dryland cropping areas of the inland Pacific Northwest of the United States. When various lime materials ar ...

- Abstract:
- ... Nitrous oxide is a potent greenhouse gas and its production is mediated by the soil microbial processes of denitrification and nitrification. A thorough understanding of denitrification drivers is necessary to accurately predict and manage nitrous oxide emissions. However, studies disagree on the utility of quantifying the denitrifier community to predict denitrification rates. This study examines ...

The composition of Pythium spp. communities differs among orchard soils resulting in variation in the relative importance of these pathogens to development of the biologically complex apple replant disease.

However, the ability of this seed meal to provide disease control even after termination of allyl isothiocyanate (AITC) emission suggested that unidentified mechanisms are also involved in suppression of certain pathoge ...
