- Honar Safar Doski added an answer:3Has anyone investigated the relationship between fertilizer (synthetic NPK vs manure) and the %N in crop plant tissues?
For some reason I am having trouble finding studies that have tested differences in plant nutrient uptake, specifically %N, in response to NPK versus manure. All of the literature I have uncovered so far tests soil nutrient response but not plant nutrients. I am particularly interested if leguminous plants may accumulate excess %N when raised in fields that have been historically fertilized with synthetic fertilizers. Does anyone know if a study like this has been published?

Waiting for your good suggestion and valuable information..
The answer of Dr. A. Subba Rao is very interesting because he points at the problems related to drought. In this context it is interesting that also here electrical field manipulation is able to give a helping hand concerning Climate Change
This was shown by the rain making specialist Bernard Vonnegut who decided to investigate the influence of negative charges on precipitation and thus the climate. He did this by using a 10 km long corona wire at 7 m height on a site near Jacksboro Texas (.us)
The results were very interesting because he indeed was able to change the rain pattern in that area considerably. A problem related to drought on a certain part on Cyprus is now under discussion. It concerns a small river deviating rain clouds.
This deviation is such that certain parts of the land do not receive the rain. The idea in now to “hide” the riverbed for the clouds so that they will pass the river and that rain will start to fall on the arid river bank and its adjacent territory after a form of Vonnegut stimulation.

- Stephen Warren added an answer:12Was agriculture a benign or malign invention?The conventional view is that the discovery of agriculture about 7000 years ago in N.Europe (as the last ice age came to an end) by concentrating the production of food in one place released man for other activities. It catalyzed the development of trading which led to the development of written records and mathematics.
On the other hand Bryan Sykes, in "Adam's Curse" (A book which charts the decline of the Y chromosome and forecasts its eventual demise [recent studies have refuted this] and has had mixed, and sometimes contradictory, reviews in Amazon) presents some interesting (I think) arguments that agriculture has had some more malign influences.
1) Nutritional status declined as the diet was then dominated by carbohydrates
2) More sedentary lifestyles led to decline in physical condition
3) Whereas the hunter gatherer lifestyle was compatible only with monogamy, a man could plant enough grain to support two or more families. Land therefore acquired value and strong, ruthless individuals could buy, extort or simply take land from weaker individuals. Ownership of land therefore became linked to wealth, power and fecundity. Women married to such men would have more children and women who were attracted by power increased as a proportion of the female population. Sexual selection therefore led to men who were increasingly aggressive and power seeking and women who tended to be attracted to such men (I realize that this is an over-simplification and exaggeration but it contains an idea which, if valid, accounts for the nature of the alpha-male and why they are nearly always promiscuous. Of course all men are not like this; some remain with a hunter-gatherer personality and others have elements of both. Women likewise, mutatis mutandis. It also accounts for the absence of drive for success in many women but not, interestingly, for male attitudes towards women).
From this we can break down the big question into smaller subsets:
a) Was this form of agriculture always inevitable or were there alternatives (at least theoretically)?
b) If there were alternatives what were/are they and what are their benefits and disadvantages?
c) Is Sykes right in his analysis and conclusions?
d) If not, why not?
e) Are there any reasons to believe that any of the alternative societies that might have evolved would have been an improvement on the one in which we now find ourselves?
argues that the existential decline of the Y chromosome has been overstated and that it has several functions that are too important to disappear. If the authors are right this removes the central plank, but not the subsidiary ones, from Sykes's book. Nevertheless there are counter-arguments to these too.
At best I believe Sykes has over-simplified an issue that is much more complex than he thinks.Following

- Anoop Kumar Srivastava added an answer:3How do different N combination ratios influence other nutrients uptake?In my work, we supply the same amount of N,P, and K fertilizer but different organic and inorganic combination ratio.The more the organic manure used, the higher the P concentration had, and meanwhile the N concentration was lower, why is this so? How does N influence P and K uptake?
Sorry , based on such nutrient ratios , diagnosis and recommended integrated system has been developed , which is so successful in many perennial fruit crops. The method also precludes the impact of leaf sampling age , you can test leaf analysis at any crop developmental stage. You can also streamline the order of nutrient deficiencies in decreasing or increasing order. so nutrient ratios have far reaching implications in the context of better understanding on nutritional characterization of perennial fruits.Following
- Narayan Sharma Rimal added an answer:10Is there any way to increase the rate of Adoption of ready -to use agricultural technologies ?
Adoption of already and proven agricultural technologies in West Asia and North Africa is a real problem. How we can improve and increase the adoption rate.
This is a complex issue basically in least developed countries with wider and varied geographical settings. However in my view Participatory Approach like Farmer Field School, Participatory Technology Development will be the best approach to increase the adoption rate of improved technology.
In addition to this, engagement of Local Social Organization (Cooperatives, Farmers Groups) in planning process and dissemination of the improved technologies will be very much helpful in reducing reluctance within the farmers associated with technologies and motivate them to adopt new and ready to use technologies together at their own farms. Thus, i believe development of technologies should be WITH FARMER, BY FARMER AND FOR FARMER so that dissemination of technologies will be much easier and hence motivate farmers to adopt those rapidly at their level.Following

- Gunda Mohanakrishna added an answer:12Is it possible to remove pesticides from water-logged soils using microbial assemblages?
Looking for viable options for remediation of pesticide-contaminated water-logged soils.
Here I can suggest bioelectrochemical system (BES) for the treatment of the recalcitrant and toxic compounds. This is the novel system where the complex mechanisms works for the degradation of organic molecules. Microbial fuel cells (MFCs), one of the applications of BES that treats organic pollutants and simultaneusly generates bioelectricity. Many recalcitrant organic pollutants including, chemical wastewater, distillery wastewater, dye wastewater, pesticide wastewater, phenol related wastewaters were stuided for the suitability to use as substrates. A large array of articles can be find in literature.
As the MFCs were found to perform very good in sediments and water-logged soils, MFCs is best option to work for the pesticides degradation.
Even though, the energy/bioelectricity produced is less, when the major aim is pollutant degradation, MFCs perform good. The energy input for MFC operation is minimum.

- Bernhard Meier zu Biesen added an answer:10Can vertical farming be used in tropical forests as an alternative to conventional (horizontal) farming?
Farming is considered to be the first cause of deforestation in the tropics. Our research team is currently looking for farming solutions that may replace conventional small- and large-scale farming in Brazilian rainforests. Our current assumption is that vertical farming, mainly conceived for urban areas, may be an alternative that has a much smaller impact on the forest because of their small footprint and diffuse spatial distribution (vertical farms scattered around the forest, instead of being clustered), thus drastically reducing deforestation. We are confronted with the following questions:
- Is there any knowledge on how productive vertical farms are in tropical forests?
- What kind of new problems would vertical farms bring for farmers?
- Can current farming products be stacked vertically?
- Can vertical farming be realised with low-tech solutions?
We would highly appreciate any feedback on these questions.
These orientations from my side:
1. Question has to be answered simply by "No", but VF can be --- in probably all agro-eco-systems --- a fantastic and trial-worthy supplement to conv. farming, also in view of the future high needs of food, industrial raw-materials, crops of biogas-units, etc..
2. I have tested this year how much I can produce in a vertical-setting on 1 square-meter; it is breath-taking, but not easily possible on large land-areas.
3. I suggest to focus on a few very practical and pragmatic part-options and test further (the 3,000 or so potential crops offer a wide spectrum of options):
-----a. Growing crops like zucchini or eggplant in mixture with maize-like plants. These offer an enormous yield-intensity.
-----b. Searching / checking / using the benefits of allelopathy-effects of plants in perma-culture-settings for VF.
-----c. Applying drip-irrigation-systems for easy irrigation and little water-consumption.
-----d. Priorizing climbing / creaping plants and letting them go-up on trees, stakes, palls, etc.
-----e. Checking the option of a potatoe-box principle: start growing on ground, then filling gradually continuously in the 1 or 2 or 3 or10 cubic-meter-box; after end of growth (period) just tearing the soil apart and picking the potaties. Many tuber-crops might offer this option for VF. The famous potatoe-box is usually 1 cub.m.
4. The systems and chances for VF depend largely on the a) technical material for erecting / constructing durable vertical levels. Best is looking for some sec.hand-material from construction-sites or factories, etc. b) irrigation demands the cheap systems of drip / trickle irrigation in case the tropical forest is not rainy enough. c) Mulching, mixed crop-stands, perma-culture or systems like that need to ensure highest yields per squaremeter.
5. With adequate agronomical creativity and good www-search you could even find solutions for a "Yes" to the question.Following
- András Bozsik added an answer:48Is a PhD a PhD?PhD = philosophiae doctor (doctor of philosophy)
The medieval university made possible the study of arts, law, medicine and theology.
Philosophy was only an introductory study for theology. „Philosophia est ancilla theologiae.” The degree of philosophiae doctor was developed in Germany in the 18th- and 19th-centuries and now it is acknowledged all over the world.
Scientists were often distinguished philosophers like Aristotle, Plato, Avicenna, Francis Bacon, René Descartes, David Hume, Gottfried Wilhelm Leibnitz.
Philosophers studied and formulated ethics, logic, metaphysics which play a central role in scientific theories and methodology. Philosophy has been always attached to the theoretical solving of humanistic and general troubles during the history of mankind.
Can one say scientia est ancilla philosophiae or philosophia est ancilla scientiae?
These days some scientists work on tiny scientific fields and are specialists of micro areas. Are they able to see the whole field or determining parts of human needs? Or are they able to contribute to the true human welfare?
What is the main objective in writing a manuscript, to distribute new knowledge or to have one more publication?
Does determine credibility of scientific achievements the credibility in scientific degrees?
There are still many kinds of frauds and other “manoeuvres”.
How to measure scientific merit?
Some examples: Some influential “scholars” requested (commanded) potential contributors before a conference to cite their, the influential “scholars’, publications in public circulars. Of course, they, these scholars, controlled meticulously the list of the submitted references but not the merit of the manuscripts. 15 researchers write individually one article a year. They make a deal and became co-authors of the other articles, thus every author has 15 articles a year. The examples may be infinite.
It would be interesting also to compare the opportunity of a native speaker submitting a manuscript in his/her mother tongue with that of a son/daughter of other nations.
Yes, it depends on the urgency of the job to be fulfilled. However, in case of university careers as you put it, the PhD degree is obligatory for senior jobs.Following
