Cool-season grasses are the most common forage types in livestock operations and amenities. Several of the cool-season grasses establish mutualistic associations with an endophytic fungus of the Epichloë genus. The grasses and endophytic fungi have evolved over a long period of time to form host-fungus specific relationships that confer protection...

Tall fescue (Lolium arundinaceum (Schreb.) S.J. Darbyshire) often forms a symbiotic relationship with fungal endophytes (Epichloë coenophiala), which provides increased plant performance and greater tolerance to environmental stress compared to endophyte-free tall fescue. Whether this enhanced performance of tall fescue exclusively results from the...

The major forces driving farm-level production for the ever-growing global population have relied upon mechanized farming techniques, synthetic inputs, and developing high-yielding crop varieties. Recently, however, there has been a gradual shift toward developing sustainable approaches addressing the potential use of beneficial traits of the soil-...

The study of interrelationships among soil health indicators is important for (i) achieving better understanding of nutrient cycling, (ii) making soil health assessment cost-effective by eliminating redundant indicators, and (iii) improving nitrogen (N) fertilizer recommendation models. The objectives of this study were to (i) decipher complex inte...

Soil microbial communities are key players in the development of sustainable food production systems. These soil microbes are responsible for macronutrient and micronutrient mineralization and solubilization in soil. Local effective microorganisms (LEM) are a locally sourced bio-inoculate, made from a fermented mixture of actively decomposing fores...
Article

Nitrogen (N) in the agricultural production system influences many aspects of agroecosystems and several critical ecosystem services widely depend on the N availability in the soil. Cumulative changes in regional ecosystem services may lead to global environmental changes. Thus, the soil N status in agriculture is of critical importance to strategi...
Article
Local effective microorganism (LEM) is an inoculant produced using leaf litter collected from forest floors near the location where it is to be utilized. While this locally-sourced inoculant is used around the world, more research is needed to fully understand the potential benefits or drawbacks of its use in agricultural systems. The objectives of...

In agroecosystems, nitrogen is one of the major nutrients limiting plant growth. To meet the increased nitrogen demand in agriculture, synthetic fertilizers have been used extensively in the latter part of the twentieth century, which have led to environmental challenges such as nitrate pollution. Biological nitrogen fixation (BNF) in plants is an...

Generally, improvement in the soil health of pasturelands can result in amplified ecosystem services which can help improve the overall sustainability of the system. The extent to which specific best management practices have this effect has yet to be established. A farm-scale study was conducted in eight beef-pastures in the Southern Piedmont of G...

Disinfecting soil can reduce or eliminate crop loss from soilborne pathogens, parasitic nematodes, and weed competition. Biosolarization combines biotoxic products from organic matter decomposition and heat from solarization. While biosolarization offers an organic option for soil pest control and avoids human and environmental health risks associa...

In order to ensure a soil system’s sustained ability to carry out ecosystem services, indicators that assess soil health are needed. We examined the capacity of nematode maturity index (MI), structure index (SI), enrichment index (EI), and trophic groups as measures of soil health, by determining soil nematodes’ sensitivity to cropping systems: rot...

A greater number of extreme weather events such as drought and hurricanes, are predicted in coming dec-ades, due to changing global climate, and they have significant impacts on agricultural systems. Runoff losses of nitrogen (N) can be exaggerated during hurri-canes due to much intense precipitation. The other extreme, drought reduces forage produ...

To assess the abundance of phosphorus-solubilizing bacteria (PSBs) and nitrogen-utilizing bacteria in LEMs. To measure the total Kjeldahl phosphorus and nitrogen (TKP, TKN), organic P (OP) and plant available phosphorus (M1) in two Red Turkey hard winter wheat (Triticum aestivum) systems. To assess differences in wheat grain content of Ca, Mg, and...

Uneven spatial distribution of soil nitrogen (N) in conventionally managed pastures is a function of various biotic and abiotic factors and results in poor land use efficiency. In this study, we measured soil inorganic N (0-5, 5-10, and 10-20 cm depth) in a 50-m grid and specific areas of interests (AOIs) from eight conventionally managed beef-past...
Article
Culturing and using effective microorganisms from locally derived microorganisms has become a common practice employed by farmers throughout Central America as well as parts of South America and Southeast Asia to control foul odors and flies around compost piles and livestock facilities. These local, effective microorganisms (LEM) are applied in a...

Biochar and biomass was applied atn the rate of 5 t/ha to soils that received arsenic containing waterat a rate of 1 mg/L arsenic (80% arsenite and 20% arsenate). After 36 days of growth of Kalmi (Ipomoea aquatica) plants, the yield parameters, such as arsenic accumulation and fate of arsenic vis-avis biochar addition had been examined. The results...

Addition of biochar to soils has the potentials to reduce the emission of greenhouse gases from soil. The primary objectives of this study were to see the impacts of biochar and the corresponding biomass application on the emission of carbon dioxide (CO 2), carbon monoxide (CO), phosphine (PH 3) and volatile organic compounds (VOCs) from soil inves...

Question
I am trying to trim and filter my de-multiplexed CCS reads. GALAXY has a tab "Metagenomics" under which it has dada2 options. I have CCS reads from PacBio. Also, any idea on what to use in R for trimming?
