Over the past three decades, soil science has undergone a significant transformation, with a growing focus on the intricate world of soil microbiology. As researchers delve into the soil's microbial communities, we are uncovering their critical roles in ecosystem health, nutrient cycling, and soil fertility. The advent of molecular genetic techniques has revolutionized our understanding of these microscopic ecosystem engineers, revealing the complex interactions within the soil.

Join the conversation to share your insights on the latest trends in soil biology.

Whether you're studying the impact of climate change on soil microbiota, the role of microorganisms in carbon sequestration, or developing bio-inoculants for enhanced crop productivity, your expertise is essential in shaping the future of soil science.

To kickstart our discussion, I invite you to read the comprehensive scientometric analysis titled "Trends in Soil Science over the Past Three Decades (1992–2022) Based on the Scientometric Analysis of 39 Soil Science Journals." This article offers valuable insights into the shifting paradigms in soil research and underscores the increasing importance of soil biology in addressing contemporary environmental challenges.

Currently, Agricultural science is advanced. Unfortunately, precise nutrient management is not implemented by all the farmers, but most of the farmers are doing annual soil tests. we need crop-specific and location-specific nutrient recommendations (like STCR equation). A precise Fertilizer recommendation for crops is required.

Hi all!

I have been trying to get a hold of official and legitimate databases or listings for online agriculture-related workshops. I know FAO has an extensive e-learning academy that offers a wide range of learning content. Are there any other similar organizations that hold online events for professional development in agricultural sciences?

Any help is appreciated.

Cheers!

I am Associate Professor in School of Botany, Minhaj University, Lahore, Pakistan. My specialization is in Agricultural Sciences (plant pathology). I have done my Ph,.D in 2016 from Faculty of Agricultural Sciences, Punjab University, Lahore. I want to do Post doc from any good University of Malaysia, Turkey, Australia, Switzerland or Italy. i have published 21 papers in national and international Journals. I am attaching my CV.

Dear ResearchGate Community,

I am conducting an analysis to compare the carbon sequestration potential of applying 1 ton of fresh organic residues directly to soil versus the application of 1 ton of the same residues after composting (meaning we would apply a lower amount: maybe 0.3-0.6 t of compost).

My objective is to quantitatively assess the differences in carbon sequestration efficiency, accounting for carbon loss through mineralization during decomposition or composting, and the long-term stability of carbon in the soil.

How do these two approaches—using an identical starting quantity of organic material—affect the net carbon balance in agricultural soils? What are the expected differences in carbon stabilization, mineralization rates, and overall carbon sequestration efficiency between fresh and composted inputs?

Additionally, how might factors such as the type of organic residues, soil properties, and environmental conditions influence the outcomes?

I welcome any insights, empirical data, or research findings that could illuminate the comparative effectiveness of these soil amendment practices.

Best regards,

I am looking for the next two publications, published in the South African Journal of Agricultural Science, in 1968: • Oberholster, R.E. 1968a, A method for separation of plant opal in soils, South African Journal of Agricultural Science, 11 (1) : 195-196, en • Oberholster, R.E. 1968b, Opal phytolith in two soil profiles on the Springbok Flats. South African Journal of Agricultural Science, 11 (4): 743-748. Much appreciated Gerhard

Do you think it is true, to see a scientific study as a source of income, from the race to be published by the journals to the publication of the symposium? Yes, money is spent on scientific efforts. And, this money must correspond to income. But the inventions, the patents that are the result of these efforts should be traded. I think that organizing so many symposiums, also being in the race for publication of articles by the open journals (or others), reduces the quality of science. What do you think about this?

Dear all,

I am working on a formula to assist farmers to have a better irrigation and water management, to help save water. We want them to know when and how much to irrigate their farming fields, we have developed a sensor to assist with soil knowledge but we also need to account for external factors. The external factors are quite a lot (around 8), and I was wondering if anyone has any experience in setting up formulas for these kind of things. If it is not possible to account for all factors, it is possible to let some out of the formula.

First of we have our sensor data, at the moment we only want soil humidity to be in the formula.

Second we want to account for climate data, wind/sun/rain/temperature (maybe air humidity). I think it is possible to not account for all of these, maybe only use rain and temperature.

Third we want to account for: type of plant/ growth phase of the plant and what soil it is grown in. This is data we need to have figured out before, external factors will not influence the value of these so we can set a vast value for this. Because the irrigation needs for an x plant in an x growth phase will always be the same. We need to connect transevaporation rate to it as well.

In my opinion the formule needs to exist out of the first and second information for sure and maybe calculate the outcome of that with the 3rd. But to be honest I do not have the experience or knowledge to figure this out. Is anyone the person or know a person to assist with this. If anyone is able to help us make this formula completely functional, we want to reward as well.

Thank you for taking the time to read this, and hopefully there is anyone with the knowledge and experience.

My sincerely, Morris la Crois

Dear Colleagues,

The growing need for food production through sustainable cultivation practices, without reducing crop yield and producer income, is a major objective due to increased environmental pollution and the gradual degradation of cultivated soils. Various compounds with bioactive properties can be utilized as biostimulants to boost plant growth and development under normal and stressful conditions. So far, six distinct categories of biostimulants have been recognized, including microbial inoculants; humic substances, such as humic and fulvic acids; protein hydrolysates and amino acids; biopolymers; inorganic compounds; and seaweed extracts, all of which are commercially available with wide applications in agriculture. The most important biostimulant effects on crops are the acceleration of crop establishment, the improvement in nutrient uptake and nutrients use efficiency, the induction of tolerance to biotic and abiotic stressors, the improvement in seed germination, the increase in shelf life of perishable products, the reduction in nutrients leaching, the improvement in root development, the removal of heavy metals from contaminated soils, the improvement in crop performance, the stimulation of the immune system of plants, the improvement in visual quality of final products, and the induction of the biosynthesis of plant defensive biomolecules. Different classification approaches have been suggested so far, based either on the origin of each biostimulant, such as biological or non-biological, microbial and non-microbial, or on the mode of action which divides biostimulants into phytohormonal and non-phytohormonal ones.

This Special Issue focuses on the roles and functions of different types of biostimulants on different agricultural and horticultural crops within the framework of sustainable crop management, aiming to gather critical and important information regarding their positive effects on plant growth and final yield, as well as their impacts on the quality of the final product. Furthermore, the major limitations of these practices as well as the future prospects of biostimulant studies will be presented.

It is a usual practice of calculating CV for rainfall/precipitation data after detrending the time series as suggested by many authors like (Giorgi et al. 2004; Blazquez et al. 2013). "Say, I have total winter rainfall data in a single time series. I calculated the detrended time series by subtracting the linear trend (or the fitted values of  the linear regression) from the actual data. I got both positive and negative values in the detrended time series (Residual). If I calculate the CV (SD/mean) of this time series, the values are infinite as the mean of the time series is nearly zero".  

Please kindly guide me. I want to know, where am I doing wrong?

Can you familiarize me with successful research examples in this field?

What are some of the most pressing issues currently facing agricultural science, and how are scientists working to address these challenges?

Open AI such as chatgpt increase speed in reviewing large volumes of papers and generating original content.

How is likely to affect students examinations especially on essays and term papers?

Our answer is YES. E.g., in RG, I exceeded +260,000 total reads, +14 books, +40 preprints and reports, +140 questions, and +5,000 answers.

Of these, the questions stand out for me, as providing a path to explore. They are the most important research tool, IMO.

Questions can reduce bias, and prepare room for a stronger paper. Knowing a good question, or reading about it, is very important to open new fields.

Now, in RG, questions can be protected from interference, as discussed in https://www.researchgate.net/post/Can_one_end_trolling_in_RG_answers

What is your experience?

Dear all,

I wonder if I can find an author that has published an article with Journal of Agricultural Science and technology. If so, I wonder how much time did it take to get your first decision and how was the exact time for your article to be reviewed and published.

Any help in this regard will be appreciated.

I only want to isolate the archaea comunity, and know how we can identify then?

As we know, there is always a fund issue in this covid period, hence it is matter of concern how to pay higher article publication charges. Pls suggest me some low cost or unpaid journals having a impact factor for publishing good research article?

Dear Colleagues and Friends from RG,

What do you think about it?

What's your opinion on this topic?

Please reply,

I invite everyone to the discussion,

Thank you very much,

Sometimes all of scientific articles are not available in google search even in another search engine. But when I intended to do a new work, so how can I know that this is first time. Even though, it may be that the work has been done before but it did not appear in my search engine. So, what could basis that we can say this is first time work or research.

Dear all, Please suggest the plagiarism checker software which is 100% free and also don't have the restriction of word limits.

The journal should be related to agricultural science.

Crop rotation is the practice of planting different crops sequentially on the same plot of land to improve soil health, optimize nutrients in the soil, and combat pest and weed pressure.

I would like to understand in which cases crop rotation it is not advantageous.

I have just been accepted in a PhD program in Environmental Science. After the first meeting with the program coordinator, I have been informed that I have to perform an 'Experiential learning' for one semester in order to 'learn how to do research'. Based on the explanation I received It's a kind of internship, like the compulsory academic internship I did some years ago at undergraduate level but here it will be in a research institution or lab. And what's very surprising for me is that during this internship-like semester what I will be doing should not have any link with my research interest nor with my PhD project. So dear friends, my questions are:

I'm now wondering if I would change a program or university. Please I need your comments to help make this issue clear.

Best,

I am working on creating a vacuum based device which can be used to collect different type of crops (like cotton, castor, grape, chili, etc.), So if am able to get a theory for calculating amount of vaccum required to collect the crop similar to vaccum cleaner it would be helpful. Thanks in advance

Hi,

I'm looking for data (mainly related to management: growth rate, canopy size, soil and climate preferences, etc.) about tropical trees used in tropical agroforestry.

Have you ever heard about a database or a source of technical information available to agroforest managers?

That would really facilitate land management and field experiments.

As always, I am trying to use these questions to centralize information from different sources. RG questions tend to be well indexed in Google for different users. Thank you for your contributions!

Best,

Thomas

The liquid fertilizer formulations are prepared by incubation of Mexican sunflower and Tephrotia vogelii leaves with water.

Grains such as barley, corn, sorghum, etc. are being sprouted and fed to livestock. Is this an economical alternative compared to concentrate feed? In light that tropical countries that do not grow these grains in large quantities, it would have to be imported and therefore a cost incurred.

And also if there are recent studies of its use in poultry? Thanks

Can anyone suggest me some Fast Publishing Journal with Low APC ( Less than 1000 usd) in the fields of agricultural science or image processing and computer vision...

The first review result should be within 1 month and publication within 2-3 months..

Could you share your experiences publishing in open access magazines in the agricultural sector, which are your favorite magazines, and why?

I am developping a research project on the use of cereal varieties mixture in order to reduce the impact of diseases and increase yields.

I am working on freezing tolerance of Ryegrass overseeded on Bermudagrass for winter greening....... Now its time for Transition back to Bermudagrass, but i am not sure about its measurement.

Some papers suggest Measurement of Both grasses while some suggest Measurement of only Bermudagrass (through Line intersect method).

I wanna publish my paper in journals without cost which are indexed by thomson reuters (isi) with moderate impact factor for agricultural Science.

In this case, I am emphasizing the basis of the index, such as:

-Cumulative, accumulated, deficit and excess rainfall values.

-Average, lowest and highest temperature values.

For example, I have historical rainfall, temperature and streamflow data consisting of about 30 years, so how can I decide the value of index based on the above values such as cumulative, average, lowest and highest values?

What is the best free software for mapping reference evapotranspiration and crop water requirement  (iso evapotranspiration curves)? Does anyone have material related to this topic?

We're looking to purchase olive pollen for an artificial pollination study. Does anyone know where we might be able to buy Olea europaea pollen?

I am doing some literature review to better understand the processes governing the biological fixation of nitrogen by non-symbiotic micro-organisms (associative, endophytic, free-living...).

I am not interested in symbiotic relations like legumes (which have their use), but rather to find solutions to promote this fixation throughout the cultivation (perhaps through composting?).

So it could be in the field or in a compost pile on the farm.

Could you share some insights?

Hi,

I'm working with a set of soil analyses obtained from an external laboratory.

Studying the results, I am highly confident that one of the analyses gave incorrect results because the values are extremely unlikely (in total disagreement with what is normally naturally occurring).

Besides, I have conducted additional analyses to triple-check this analysis.

The results I have obtained contradict, as I expected, the anomalous data.

The problem is, that the method I used is not the same as the initial method (unavailable at my lab), but is supposed to measure the same variable.

Now that it is time to write a research article, what would you do to overcome this problem?

Should I explain that for this particular analysis, results were abnormal and were not considered further?

Should it be done early in the results section, or later in the discussion section?

How have you dealt with unexpected/erroneous data with your research, when you cannot repeat the same analysis?

Will a journal accept to publish results which include one bad apple, while the rest of the basket is fine?

Best thanks in advance Johann HUMER, Austria

Is their relation between the coleoptyl or mescotyl of sorghum varieties and infection?

• When we apply granular basal fertiliser such as compounds fertiliser like Compound D in maize we apply it per plant using fertiliser cups. Usually we divide the amount of fertiliser in grams per hectare by the plant population to get the amount of fertiliser in grams per plant.

e.g. 300kg per hectare of compound D in a maize crop spaced at 75 cm inter-row and 25cm within the row 300 000g/53 333 plants = 5.6 grams per plant. If I wanted to conduct a maize experiment in a pot I would just apply this amount of fertiliser per pot.

• However I could weigh the soil that the pot can carry and do a simple proportion as follows assuming that a hectare furrow slice weighs 2 200 000 kg of soil as follows:

300 000g fertiliser →→ 2 200 000 kg soil

X g fertiliser →→ 10 kg soil

= 1.36 grams per pot

In the first method a maize plant receives 5.6 grams whether it is growing in the field or in a pot with 2 kg soil or a pot with 10 kg soil. In the second method for a maize plant to receive the same amount of fertiliser as in the first method it has to be grown in a pot that carries 41 kg of soil. The amount of fertiliser increases with increase in pot size.

How can we reconcile this?? Which is the correct method for the determination of fertiliser per pot?

The tobacco plant is known to spread in most parts of the science, but the yield of the product is related to several factors, including the pH of the earth.

Rice is the seed of the grass species Oryza sativa (Asian rice) or Oryza glaberrima (African rice). As a cereal grain, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia. It is the agricultural commodity with the third-highest worldwide production (rice, 741.5 million tonnes in 2014), after sugarcane (1.9 billion tonnes) and maize (1.0 billion tonnes).

Sugarcane is a member of the grass family and is valued chiefly for the juices that can be extracted from its stems. The raw sugar that is produced from these juices is later refined into white granular sugar. As a sugarcane plant matures throughout the growing season, the amount of total sucrose in the cane increases. Most of this sucrose production occurs when the plant has fully matured and begins to ripen.

Dear one & all Kindly give the details for the similarities and difference between Article, Communication, Notes, Reports, Full paper, Featured Article, Perspectives, Review, & Tutorial ... How to select the suit one? What are the criteria for this? Most us select on the basis of length our findings; and present and previous work summery. This discussion is seems to be very simple.... but it is always better if we get an better idea of each one... May be it will help for research beginners..

I am currently working on barley, have some diseases?

I am confused about calculating the amount. I took 0.3g of dried sample and dissolved it in 50ml of solvents like methanol/chloroform etc. I filtered the solvent and do use 1ml of the extract for analysis. When I am calculating the amount of the respective contents from the standard curve in the equation C=c1XV/N [c=Total content of the phenol in mg/g; C1=the conc. of gallic/tannic acid established from calibration curve in mg/ml; V=the volume of the extract in ml and N=the wt of the plant extract in gm].

Is the V is 50ml and N is 0.3gm?

What determines human behavior in daily life?

Soil texture, determined by the measurement of particle size distribution, introduces three variables to create texture classes.

However, if we forget about the three fractions (clay, silt and sand), a the end of the particle sizes are distributed along a continuous axis (one dimension).

Could it be possible to derive a single number to characterize soil texture, to make whatever calculation more useful?

Some people use sometimes sand content, or clay content, reducing the (somewhat arbitrary) three dimensions of texture to a single value, but there should a mathematically more acceptable way to reflect soil particle size distribution withtout loosing too much information?

What do you think?

The average or medial particle size could perhaps be more interesting? Or some sort of the average particle size of the interquartile of the distribution (if it is unimodal...)? Any thoughts?

Not being able to reduce soil texture to a single value often feels constraining to make relevant data analyses...

Climate changes are hitting us in a noticeable rate. The impacts are very strong on all life aspects specially agriculture. Decision makers, researchers and many others are working hard to mitigate those changes. However, we still notice that climate changes are speeding ahead of us and will continue so for some time.

So, Do you think that development in agricultural sciences and other related fields can cope with those climate changes?

I am looking for large datasets including information on soils (texture, depths, carbon , etc.) and their location (GPS coordinates or climates data).

Any suggestions?

Any large studies which would have left their data available for free in repositories?

My objective is to help people find time series on soil carbon on this thread (easily find this discussion with a google search). Thus it could a great reference and link list.

Thanks!
