because their research has revealed that soil K testing is of no value for predicting soil K availability and that KCL fertilization seldom pays.
Test values fluctuated drastically did not differentiate soil K buildup from depletion and increased even in the complete absence of K fertilization.

There is growing concern regarding the global decline of honey bee populations and the implications of this demise for the pollination of crops.
In the future we may rely on other insect species to perform crop pollination services including naturally-occurring native
Pollination success of generalist plants tends to be positively related to pollinator diversity so any habitat modifications that increase the number of pollinating species present at a site would tend to be of some inherent value.
But changes in grazing pressure and pollination can also affect the genetic composition of natural plant populations according to a new study.

For the first time it could be demonstrated with smoking pregnant women and their children how exposure to tobacco smoke affects the development of human immune system on molecular level.
For some time now the impact of environmental stressors during pregnancy on allergy risk among newborn children is a main research topic at Leipzig Helmholtz Center for Environmental Research (UFZ.
Former studies have already proven that smoking during pregnancy can harm the unborn child: Newborns from smoking mothers have shown low birth weights and impaired lung functions;
To investigate the relationship between smoking mothers during pregnancy on the one hand and their children's risk of developing allergies on the other the scientists from Leipzig examined microrna-223 microrna-155 and regulatory T cells--not only in the blood samples of pregnant women (36 weeks pregnant
) but also at birth in the cord blood of their babies. At the same time questionnaires were filled out and urine samples of the pregnant women were tested to substantiate the effect from exposure to tobacco smoke
and/or from volatile organic compounds resulting from smoking. From the pool of mothers participating in the LINA-study 315 mothers (6. 6 percent of whom were smokers)
Now the immunologists from Leipzig explicate we will know more about the molecular processes that trigger off stressors from smoke during pregnancy.
#Understanding soil nitrogen management using synchrotron technologyas food security becomes an increasingly important global issue scientists are looking for the best way to maintain the organic matter in soils using different methods of fertilization and crop rotation.
Indeed fertilization has had a profound effect on humanity as a whole. The downside of nitrogen fertilization is that run off of nitrates to the surface waters or leaching of nitrates to groundwater cause problems with water quality and eutrophication in lakes.
The recent algal blooms on Lake Winnipeg are a prime example of this nitrogen pollution.
To obtain the snack researchers enriched apple slices with mandarin juice using a technology of impregnation developed
This was restoration not fertilization said Battles. We were only replacing what was lost. Researchers monitored the forest over the next 15 years comparing the treatment area with an adjacent watershed that had the same characteristics
Honeybees are one of the most important bee species in the world in terms of their contribution to food production through pollination.
These benefits may include for example reduced pollution outflow and erosion and better wind protection pest control and pollination.
and vegetable crops around the country in an approach known as managed pollination It involves placing bee hives in fields
when crops are ready for pollination. The biggest impacts from decreased hive numbers will be felt by farmers producing crops with high pollination requirements such as almonds.
Consumers may see a lowered availability of certain fruits and vegetables and some higher costs explained Fell.
Honeybees are not the only species of bee that can be used in managed pollination. If colonies continue declining Fell believes that there will be an increase in the use of other species including the bumble bee and alfalfa leafcutter bee.
In addition they are not as easily managed for pollination as the honeybee. The major advantages of using honeybees are ease of movement both in

One week after conception embryos from all of these sheep were transferred to normal weight normally nourished sheep for the remainder of pregnancy.
and urban areas and to enhance pollination services for crops and biodiversity. Under current agri-environment schemes the UK Government pays farmers to manage their land for the benefit of particular habitats
because the sugar gave them extra energy to handle the burden of pregnancy --but then had lower reproductive rates as the study progressed partly
because bees play a pivotal role in crop pollination agricultural yields and therefore food supply and prices.
and increasing the chance of pollination. An infrared camera from Goleta-based FLIR captured time-sequence thermal photography of Chanel as her spadix the tall core spike that houses both female and male flowers heated up to nearly human body temperature.

Julia Calderã n-DÃ az a Phd candidate at University of College Dublin said pregnant sows placed on cushioned flooring would have a lower risk of being compared lame with sows placed on concrete.
In this experiment researchers studied the effects of two types of flooring on pregnant gilts in Ireland.
One hundred sixty-four pregnant gilts were divided into two groups. One group was housed on concrete slatted floors
The replacement gilts were observed from the time they were bred until 110 days into their pregnancy.
Dr. Alan Fahey a lecturer at the University college Dublin said the gilts were studied during two pregnancies.
The results were similar during both pregnancies. Sows housed on rubber mats had reduced a risk of swelling
In the European union pregnant sows must be housed group four weeks after breeding until one week before farrowing.
Calderã n-DÃ az said other countries are likely to use group housing for pregnant sows in the near future.
In late fall and early winter pregnant females migrate to waters off the southeastern U s. to give birth.

Fisher recommends diversifying diets in pregnant and nursing women since diets are determined long before they taste their first bite of solid food.
But a Kansas State university researcher found that inflammation that occurs naturally in dairy cows the first few days after giving birth may play a surprisingly beneficial role in the complex process of going from late pregnancy to lactation.
To test whether such a carbon dioxide fertilization effect was taking place in forests Keenan Richardson
Contemporary nitrogen fertilization practices are not environmentally or economically smart says Busov who studies the functional genomics of plant development.
They can suck some of the excess nitrogen from crop fertilization out of ground water. That's good for the plants and good for nature the researcher observes.
because it is a very important element for children and pregnant women. The concentration of nutrients in animal food products is linked to the diets of the animals reared.
Iodine is necessary for the metabolism especially during pregnancy and infancy. Iodine deficiency can cause scurvy which has historically been a big problem the world over particularly in populations at a distance from the coast who did not eat much fish
In normal pollination sperm-carrying pollen grains land on the pistil's tip or stigma and grow tubes down its style to reach the ovaries in the ovules at the pistil's base.
but fertilization often fails at the pollen tube burst -and-release step. Among crop plants pollination means food.
Understanding this molecular back-and-forth at all the different levels and stages will be useful to either engineer the process
#54%of pregnant women use insecticides that are harmful to the fetus, Spanish study showspregnancy and infancy are the periods of greatest vulnerability to the use of household insecticides.
Spanish researchers have described the use of domestic pesticides during pregnancy and the first year of life in nearly 2500 women and children in Sabadell Guipã zcoa and various areas of Asturias and the Valencian Community.
In 2003 and 2008 the authors monitored the women who agreed to take part in the project from the beginning of their pregnancy until birth and during their offspring's first few years of life.
Exposure during pregnancy or infancy proves to have a negative impact on fetal growth and neurological effects as well as increasing the risk of childhood leukemia she continues.
The results show that 54%of pregnant women used some kind of insecticide inside the home
5%throughout the whole year 75%seasonally and 20%on an occasional basis. The most frequently used method in the bedroom was the electric device at 62%.47%of pregnant women used insecticides in the rest
Only 1%of women used insect repellents during pregnancy. 10%of pregnant women used outdoor insecticides such as in gardens or vegetable plots and yards with plants:
53%during pregnancy and 26%during infancy. In contrast the use of the electric device remained constant.

and measurements were taken of fetal heart rate and motor activity. The blood samples were tested for levels of 11 pesticides and 36 polychlorinated biphenyl (PCB) compounds.
However recently there has been a lot of concern that the decline of pollinators might result in pollination limitation of insect-pollinated crops.
'Rachael Winfree a leading pollination scientist from Rutgers University New jersey USA comments'This is an interesting timely and comprehensive study that tests several ecological hypotheses to answer an important question:
Shorter lactation periods could mean shorter gaps between pregnancies and a higher rate of reproduction.
and vegetables depends on animal pollination and we know that most crop pollination is done by wild pollinators.
Biodiversity is important to ensuring we don't lose that service. Relying on a few species could be risky in a changing environment he added.

Indeed he believes farmers will benefit from healthy pollinator populations as they provide substantial economic benefits to crop pollination.
For instance Kikuyu women in Africa smear themselves with the sap of fig trees to ensure pregnancy..
While 50 years of inorganic fertilization did increase soil organic carbon stocks in a long-term experiment in western Kansas the practice seemingly failed to enhance soil aggregate stability--a key indicator of soil
Fertilization typically leaves behind more crop residues in fields he explains which in turn can boost soil organic carbon levels.
When he tested soils from the experimental plots he saw soil organic carbon concentrations rise gradually with increases in nitrogen fertilization at soil depths from 0 to 6 inches although not at deeper ones.
Similarly phosphorus fertilization increased soil organic carbon at depths of 0 to 3 inches and 6 to 12 inches.
Because tillage periodically disturbs the soil it may also negate any benefits of fertilization. Blanco is now testing these hypotheses in three additional long-term experiments in Nebraska that encompass a wider range of tillage practices
The hypothesis is that inorganic fertilization combined with conservation tillage--strip till no-till and others--may improve soil structural properties relative to conventional tillage systems.

Ovaries are the female reproductive organs that produce eggs that are fertilized for pregnancy as well as secrete hormones important to bone and cardiovascular health.
As the need for carbon sequestration biofuels and other forest products increases the study suggests that there might be unintended consequences to enhancing ecosystems using fertilization.

#Two new studies show why biodiversity is important for pollination services in California almondagricultural demand for pollination is growing more quickly than the supply of honey bees the dominant species managed for crop pollination.
Increasing the efficiency of pollination represents a way of increasing crop yield without any increase in agricultural intensity or area.
Biological sciences shows that the pollination effectiveness of honey bees in California almond orchards was greater in the presence of other bees.
Almond is a crop highly dependent on honey bee pollination and is a $3 billion industry in California.
and their pollination effectiveness was greater than in orchards where other bees were absent. Furthermore orchards with wild bees had a greater proportion fruit set.
These findings show that wild pollinators not only contribute directly to almond pollination but also indirectly through increasing the pollination service provided by the honey bees.
A second study in the same system published in Global Change Biology found two other mechanisms by which pollinator diversity improved pollination service to almond.
Firstly they found that honey bees preferred to visit flowers in the top parts of the almond trees.
Where wild pollinators were present they often visited the lower parts of the trees filling the gap in pollination service left by the honey bees.
Secondly in high winds orchards with only honey bees present had almost no pollination service as the honey bees were not flying.
In orchards with a diversity of pollinators pollination service was buffered to an extent by the wild bees.
therefore help sustain pollination service under extreme weather conditions when the service by honey bees declines.
The findings presented in the two articles highlight different ways biodiversity is important for pollination service.
because it causes stillbirths abortions and fetal defects in pregnant cows and ewes. It has spread rapidly throughout Europe since its discovery in Germany less than eighteen months ago (in October 2011.

If the soil is the source this could lead to depletion of this resource without fertilization.
An estimated 35 per cent of global crop production depends on petal-mediated animal pollination but a decrease in pollinator numbers across the world has started to limit the odds of pollination

The results confirm that foliar feeding is a suitable tool to complement the traditional methods of nursery fertilization based on the radical absorption (pointing out the urea as the most efficient fertilizer.
The excessive fertilisation (eutrophication) of our seas results in an over-production of algae commonly known as seaweed.
which otherwise contribute to the excess fertilisation of water bodies and partly when we cultivate algae that actually absorb nitrogen and phosphorus from the sea.
