Dissipation and residues of trifloxystrobin and its metabolite in rice under field conditions
Residue analysis of trifloxystrobin and its metabolite (CGA 321113) in rice matrices, paddy water, and soil was developed using the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method and high performance liquid chromatography tandem mass spectrometry (HPLC‐MS/MS). The method was used to evaluate the dissipation rate of trifloxystrobin and CGA 321113 in rice seedling, soil, and ...

Uptake and translocation of lead and pyrene by ryegrass cultivated in aged spiked soil
A greenhouse study was conducted to investigate the uptake and translocation of lead and pyrene in ryegrass (Lolium multiflorum L), cultivated in spiked soil. After ageing, the pots were cultivated with ryegrass seedlings to investigate soil-to-plant transfer characteristics of lead and pyrene. In the spiked soils, the biomass of plants was not significantly lower in comparison with the control, ...

Organically complexed iron enhances bioavailability of antimony to maize (Zea mays) seedlings in organic soils
Antimony (Sb) is a metalloid belonging to group 15 of the periodic table. Chemical similarities between arsenic (As) and Sb produce concerns about potential health effects of Sb and enrichment in the environment. Antimony is found in oxic environments predominately as an oxyanionic species, antimonite (Sb[OH]6–). As a result of its net negative charge, Sb[OH]6– was not initially predicted to ...

Tips for Solarization
1- In order to make plain use of sun energy during the application of solarisation, the cover should be cleaned if there is any dust over it. 2- The area of application that will be treated should be processed up to 30-40 cm depth at first, the surface of ground should be balanced and rocks should be taken out. 3- To increase the heat conductivity of the soil you should water ...

3-D Woven Technology: The “Next Generation” in Turf Reinforcement Mats
The designers at Propex have taken the technology in their high performance turf reinforcement mats (HPTRMs) and used it to design the next generation of turf reinforcement mats (TRMs). These new netless, composite-free three-dimensional woven TRMs are designed to deliver superior, long-term performance, and are proven to outperform traditional methods like rock riprap, concrete paving and first ...

Scouting for pest in Iowa cover crops
Landscape diversification, including the use of cover crops, can provide habitat and forage for beneficial insects. This is especially true in the spring when there is a lack of food. Alternatively, cover crops can also support field crop pests, including moths, beetles, flies and slugs. The early spring vegetation, sometimes called a “green bridge,” provides resources until the row ...

Defense characteristics of seral deciduous broad-leaved tree seedlings grown under differing levels of CO2 and nitrogen
Mixed broad-leaved forests are abundantly populated by several kinds of herbivore species in northern Japan. The life of herbivores depends strongly on the quality of food leaves. Leaf quality is changing with increasing atmospheric CO2 and nitrogen deposition. Four seral species of deciduous broad-leaved tree seedlings (alder, birch, oak and maple) were raised in all four combinations of two ...

Talk about the Benefits of the Nursery Seedlings
Today I want to talk to you about the benefits of the plug seedlings of the nursery seeding planter. Everyone knows that the plug planter is relatively common in our lives. Using it can bring us many benefits. Below, the editor will briefly explain to you what are the advantages of the tray planter? 1. The main substrates for plug seedlings are peat soil, vermiculite, perlite, and other light ...

Influence of microbial activity on plant–microbial competition for organic and inorganic nitrogen
Abstract To investigate how the level of microbial activity in grassland soils affects plant–microbial competition for different nitrogen (N) forms, we established microcosms consisting of a natural soil community and a seedling of one of two co-existing grass species, Anthoxanthum odoratum or Festuca rubra. We then stimulated the soil microbial community with glucose in half of the microcosms ...

A Guide to Compost Sheep Manure for Organic Fertilizer
Sheep manure contains protein, organic acid, cellulose, aliphatics and so on, and its organic matter content is higher other livestock manure. Without fermentation, sheep manure has various harmful bacteria that cannot be directly used on plants growing, or there would bring germs and parasite spreading. What’s worse, without proper disposal, sheep manure would generate heat to consume oxygen in ...

N-(N-butyl)thiophosphoric triamide/NBPT
Urease inhibitor is a kind of substance that can inhibit the activity of soil urease, and it is a new technology which has been studied in urea or nitrogen compound fertilizer. Using soil urease inhibitor can effectively slow decomposition of urea into ammonia process, reduce soil NH4 + and NH3 concentration, soil fertility and crop fertilizer synchronization. NBPT is the most effective inhibitor ...

N-(N-butyl) Thiophosphoric Triamide Solution
N-Butylthiophosphoric triamide (NBPT, hereinafter referred to as "NBPT") is currently one of the most effective soil urease inhibitors. Agricultural fertilizers, mainly nitrogen fertilizers, are quickly decomposed by urease in the soil under normal use. This not only wastes a lot of nitrogen fertilizer resources, but also increases the cost of crop production, and brings a series of problems such ...

What are bioplastics and where are they used?
Bioplastics are biodegradable plastics. They will typically break down completely in three to six months whereas regular plastics can take up to 1000 years to break down to the same extent. Biodegradable plastics could play a key role in helping to solve the problem of plastic wasted. Here, plastic manufacturing specialist Ansini provide a quick guide to what you need to know. Understanding the ...

The value of seed harboured in Mediterranean temporary ponds
Temporary ponds and their varying water levels provide the conditions for valuable wildlife habitat. A study in Crete, conducted under the LIFE-Nature project1 Actions for the Conservation of Mediterranean Temporary Ponds in Crete, has demonstrated these ponds contain varied collections of seeds and that these ‘seed banks’ could play an important role in vegetation recovery after ...

Improve Fall Nitrogen Practices
In most of the US, this fall was a wet one. Chances are, you didn’t get much of a chance to get fall anhydrous in the ground. Beacuse of this, we wanted our agronomist, Barry Anderson, to answer a few of our burning questions related to fall nitrogen application. You may have missed the window this year, but here are some tips to keep in mind for next year. 1. At what rate/ ...

Family farms can be competitive by focusing on conservation and stewardship
While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...
