Stability of Cytoplasmic male sterility in maize under different environmental conditions
Cytoplasmic male sterility (CMS) is a maternally transmitted trait, whereby a plant is unable to produce viable pollen. Studies have revealed that this trait is a tool for enabling efficient and reliable coexistence between genetically modified (GM) and non-GM cultivation by biocontainment of GM maize (Zea mays L.) pollen. Maize has three types of male-sterile cytoplasm (T, S, and C), the ...

NPK Compound Fertilizer Development and Fertilizer Plant Production
Chemical fertilizer provides nutrients for continuous agricultural production, but single chemical fertilizer hasn't high utilization rate, limited promotion ability to crops, and a large amount of application is not conducive to crop growth. NPK compound fertilizer production has become the main trend of fertilizer. The granulation process of NPK fertilizer production line can make basic ...

NPK fertilizer granulation for slow-release granular fertilizer
Slow-release fertilizers mainly apply modern plant nutrition and fertilization theory, and take into account the law of crop nutrition demand, adopt some control mechanism technology to delay the release mode of fertilizer in soil, so that nutrient release mode and crop nutrient absorption are coordinated or synchronized. NPK fertilizer granulator machine makes powdery fertilizer into ...

Influence of nitrogen fertilizer on Cd and Zn accumulation in rapeseed (Brassica napus L.) biomass
Diffuse soil contamination with heavy metals and Cd in particular is a matter of serious concern. Application of conventional remediation methods usually is not feasible due to the large territories and relatively low heavy metal content. Thus, phytoremediation is seen as an alternative. Rapeseed was grown on Cd and Zn contaminated as well as clean soil under the greenhouse conditions. Solid and ...

Burn it no more!
The other day I came across an old news article from 2008 about a Dutch energy plant that burns 485,000 tons of poultry litter each year, converting it into renewable electricity. Wow, I thought. That is an old-fashioned way of getting rid of poultry litter – they must be releasing some 14,550 tons nitrogen gas into the atmosphere. All this to produce 270,000 MWh of electricity, 890,000 MWh ...

The Importance of Leaf Area Index (LAI) in Environmental and Crop Research
Leaf Area Index (LAI), which is used as a measure in hundreds of studies on forests, crops, climate and the environment, is calculated as half the area of all leaves per unit area of ground. It is measured as the leaf area (m2 ) per ground area (m–2) and is unit-less. So, a plant with a LAI of 2 has an amount of leaves that can cover a given area two times. LAI is calculated for a plant or ...

Palm oil: not the evil we think it is
Oil palm is a globally important crop, but our hatred of it stops us from pushing for better ways to develop it. The oil palm, one of around 2,600 species of palm, must be one of the most hated plants on Earth. Ask any self-respecting environmentalist, and his or her face is likely to turn red with anger at the mere mention of its reviled name: Oil Palm. The oil palm is the Lord Voldemort of ...

19 Things the AP Got Wrong
The Associated Press recently published an article on “the secret environmental cost of U.S. ethanol policy.” There is much in this article that is too misleading, poor or deficient analysis, over-simplistic, or poorly drawn conclusions to comment on, but here are 19 big things the AP got wrong. The article seems to put the blame on Obama the candidate and the Obama administration. ...

CO2 Shortage in the UK set to Disrupt Food Supplies
What is Carbon Dioxide and how is it used in the Food and Drink Industry?Carbon Dioxide (CO2) is a chemical compound that is an odourless and colourless gas at room temperature. It enters the atmosphere through the exhalation of organisms and the combustion of matter as a byproduct of industrial production. CO2 has a wide range of uses across many different industries, in particular the food and ...

Two Cases of Misleading Environmental Declarations Due to System Boundary Choices
Abstract Environmental Product Declarations (EPDs) on electricity and nitrogen fertiliser are used to illustrate how a declaration or labelling* based on data from the current supply chain can be misleading when the production capacity in the supply chain is constrained. Three ways of avoiding such misleading declarations are suggested. Introduction: The cause of deception As a specific ...

Leaf area - How & why measuring leaf area is vital to plant research
It is easy to measure leaves, and they are also the parts of a plant most responsive to their environment. The combination of these two factors makes leaf area measurement extremely useful to scientists and growers. Besides, leaves are one of the main plant organs and are responsible for the productivity of a plant, and on a larger scale, of an ecosystem or a farm. Therefore, an understanding of ...

Influence of environment on plants
There is no denying the importance of light for the growth of plants; however, there are many other environmental factors—such as temperature, moisture and nutrient availability, and soil type–that also influence plant growth. These factors do not act in isolation and are, many times, correlated. So, it is interesting to see how light works in combination with other resources to ...
