Hello.

​

My name is Reinalto. I am a student at the Federal University of Lavras - UFLA, Lavras, Minas Gerais, Brazil ( the most famous university in studies related to agriculture, soils and zootechnics in the country - at least the most traditional). I'm part of an extension group at my college, called "G-Cia", which is a collaborative agricultural extension group. Every Wednesday at 6 pm (Brazil time) we have a meeting where we focus on training our English and having contact with people from abroad.

Next Wednesday, September 20th, we are looking for people who are researchers, teachers or agricultural professionals to have a talk or chat with us. The objective of the group is to really have contact with someone from outside who can add our vocabulary and generate a culture shock.

I’d like to go to school to study agriculture, the plant side of the field. I’ve just heard so many differing statements. So, is agriculture going to be a lucrative path, or is there a money ceiling that I’ll hit? Does it simply depend on the specific route you go down? If so, what are my options if I want to make a lot of money and also be able to grow in the field even after I find stability? Also, what about genetics in the agriculture field?

Here are some things i’ve heard often while researching: Plant science isn’t worth it Agricultural engineering, or any other type of engineering degree in this field, isn’t something you’ll be able to pursue as you’d imagine. The tech-y and science side (like diagnostics and bioprocessing) is booming, while the environmental side isn’t doing so well. Agro tech is generally the way to go.

It didn’t bloom in spring. Is it possible to do something and save it?

Hey everyone! I'm currently working on my electrical ing. degree thesis on AgriPV systems, particulary on sweet cherry. I'm looking for sweet cherry light needs/saturation on each of their growth states but I've struggled to find what I need. I've found info on the saturation at around 500-700 umol/m2s, but I guess that's only when the leaves are fully grown. Where can I find more info on the subject? Anything would be of great help!

Cheers

Long story short, I've decided to learn how to code as a hobbies. I just started one of those free courses from Harvard to learn python and was wondering if it can actually be useful in my career. What areas can I work in as an agronomist if I know how to code?

Hi guys,

I'm working on a project that aims to replace (at least lower) the use of chemical pesticides and herbicides in farming with the use of high value weeds and plants that can naturally replace the chemical treatment. So for example , if hedgerows (the edges of the field or the surrounding of a crop) made with high value weeds can be incorporated to fixate nitrogen or to fight and resist a given disease, or have a positive impact on the crop, etc...

My mission is : to build a database with high value weeds and plants, and their effects. For example the database should look like :

​

​

I'm looking for any already existing database, research or any resource that tackle something like this.

NB: I'm not an expert in farming , I'm just a data science student dealing with agriculture related problems. So please forgive my ignorance. I would be very happy to learn.

Hi I’m currently in a community college getting my associates in crop science and crop production and for my dreams and future is for one day own fields and crops and farm land but is the this career going to help me along the way? Let me tell you something about my self I’m a city boy who’s tired of the city and always found interest in field work and so far I’m loving it because it’s a huge change of pace and very relaxing to me comparing to other jobs and my question is if this career is going to help me reach my goal or give knowledge of what to do. Right now I’m very early into this career I can do a transfer to a university after 2 years or is my associates degree enough to get the knowledge I need? Thank you I would appreciate the advice and I’ll answer questions if needed!

My wife and I found out today, August 8, 2023, that we will inherit an eight-plus acre property in November. The land has been in her family for 95 years and has operated as a vegetable and flower farm with a roadside stand the entire time. We’d like to continue the tradition, but we need some guidance, as we also found out that it barely breaks even.

We run the flower operation on 1/4 of an acre, while relatives grow produce on six acres. The operations are separate in terms of space and accounting, which is how we were blindsided by the lack of profits on the produce side. Our flowers are profitable.

The farm has never grown fruit, had animals, or even compost. For having only six farmable acres, the farm has been run conventionally without a thought given to long-term sustainability. For example, the soil is literally sand, tilled to the fine texture of a beach. Flowers and weeds grow well, but produce gets blossom end rot or does not reach full potential.

Additional info, features, and concerns:

• We are in Wisconsin, zone 5b
• We are both 41 and have three kids under 8
• The property is a long rectangle, 300 feet east to west, 1300 feet north to south
• Suburban-type houses are on all sides, comprising 22 adjacent neighbors
• No irrigation
• On a well, no city water or sewage
• No fences, so deer and rabbits are constant problems
• Thrips, aphids, Japanese beetles, horn worms, and cabbage moth worms are constant problems
• There’s a uninhabited single-story frame house with two beds/one bath built in 1890 that has a mold problem that can be smelled from outside
• There’s a two car garage built in the 1950s that raccoons made their home in for many years
• There’s a pole barn built in 1960s that has a dirt floor, a caved in roof, and a sliding door that won’t shut
• There are five 48-foot long hoop houses (currently used to store tools and tractors)
• 2 acres of forest
• A section of a several mile long ravine runs west to east on the back side of property through the forested area
• There’s a 1986 John Deere 900HC tractor

This seems to be golden opportunity to create a proper farmstead—as in living there, putting things right, and making money; however, we don’t have much to spend and it can’t take decades.

So, I am looking for detailed guides that specify low-cost, straightforward steps that will allow us to turn this worn-out land into something green, profitable, and beautiful. I want to get started the day we get the keys and never look back. Please, please help…and thank you!

I'm growing Broccoli microgreens. However the seeds are treated with Thiram. Is it safe to eat these microgreens knowing that they are harvested after around 14days which might not be enough for Thiram to completely decompose? Thanks

I’m a software engineer that wants to immerse himself into agriculture.

I’m thinking of moving to Montana or Iowa, learn to farm and gain knowledge.

I care about building software that advance agriculture

Any advice on where to go, resources, material, anything is appreciated

Hello everyone,

As part of my thesis in environmental management at the University of Brussels, I am carrying out a study on alternative farming techniques to conventional industry. The aim is to evaluate empirically whether there is a real change in practice among farmers and/or enthusiasts.

Through this questionnaire I would like to ask you why you think it's necessary to revisit the classic/productivist agricultural model, and which eco-friendly techniques do you think have the best chance of being implemented sustainably in our agricultural landscape.

I would be extremely grateful if you could take 5 minutes of your time to answer this quick questionnaire : https://docs.google.com/forms/d/e/1FAIpQLSfL4xS53iCwYQ3wgTNot2-L_vMGfMUiUyu_Rz9zz8Mi9lm8qw/viewform

Best regards,

Hi friends, I hope all is well. I want to know if you have any knowledge about how to better the exporting to United States. I have an hydrangeas business in Colombia, currently I’m sending with exporting company’s, but I want to better my business in administrative and comercial terms, I want to get new clients or something like that, please recommend to me some ideas to potential my business.

Hi guys

I want to determine the optimal distance (inter spacing) between 2 plants with respect to the root competition. Imagine I want to plant tomato, So what should be the optimal inter-spacing between the tomato plants with respect to the root competition between tomato plants.

My question is : Given the root length, width , depth ... , how to model the optimal distance between 2 plants.

I'm looking for any mathematical model or any research that tackle the optimal distance (inter spacing ) between 2 plants with respect to the roots (root competition).

Note: I'm not a biologist, just a data science student. I'm open to any biology/math resources and any other inspirations or approaches.

Hi guys,

Microalgae are organisms that can grow in aquatic environments and use light and carbon dioxide (CO2) to create biomass. Research showed that Microalgae's biomass can be used as a bio-fertilizer.

My mission is: to find the optimal field patterns . I mean the optimal spatial arrangement (distribution) of plants in a given area. To elaborate more, I need to consider if I plant a given land in raw (strip) pattern or rectangular pattern or maybe hexagonal or circular pattern, can this boost the crop yield or optimize the bio-fertilizer or the water management.

Note: I'm not a biologist, Just a data science student. I'm open to any biology/math resources and any other inspirations or approaches.

Hi guys,

Microalgae are organisms that can grow in aquatic environments and use light and carbon dioxide (CO2) to create biomass. Research showed that Microalgae biomass can be used as a bio-fertilizer.

My mission is: to find which plants in the world are best suited to arid climates and to arid soil that was treated using the Microalgae biomass.

With the help of a Reddit hero "CarverSeashellCharms," I was able to model which plants in the world can adapt to arid climate/arid soil based on a theory in biology named Species Distribution Modeling (SDM). This model takes in the geographic occurrences of a given plant in the world and based on the soil characteristics and climate variables, it can predict the probability of growing that plant (suitability) at any point in the world. The problem here is: this model considers only the soil characteristics and the climate variables without considering the Microalgae biomass (bio-fertilizer) effect.

So this is my approach to how to model the bio-fertilizer effect:

I'm into calculating a score that models the bio-fertilizer effect (effectiveness) and determining a new final score based on the suitability probability and the bio-fertilizer score.

Let's assume the following values:

Plant Nutrient Requirements:

Req_N = 0.3

Req_P = 0.05

Req_K = 0.2

Soil Chemical Characteristics:

Soil_N = 0.15

Soil_P = 0.02

Soil_K = 0.1

Fertilizer Chemical Characteristics:

Fert_N = 0.1

Fert_P = 0.02

Fert_K = 0.15

Step1: Calculate the nutrient deficiencies/excesses in the soil compared to the plant's requirements:

Deficiency_N = Req_N - Soil_N = 0.3 - 0.15 = 0.15

Deficiency_P = Req_P - Soil_P = 0.05 - 0.02 = 0.03

Deficiency_K = Req_K - Soil_K = 0.2 - 0.1 = 0.1

Step2: Calculate the nutrient contribution of the fertilizer to address the deficiencies:

Contribution_N = min(Deficiency_N, Fert_N) = min(0.15, 0.1) = 0.1

Contribution_P = min(Deficiency_P, Fert_P) = min(0.03, 0.02) = 0.02

Contribution_K = min(Deficiency_K, Fert_K) = min(0.1, 0.15) = 0.1

Step3: Calculate the overall nutrient contribution score (F):

F = (Contribution_N / Fert_N) * (Contribution_P / Fert_P) * (Contribution_K / Fert_K)

= (0.1 / 0.1) * (0.02 / 0.02) * (0.1 / 0.15)

= 1 * 1 * 0.6667

≈ 0.6667

Step4: Calculate the new score based on the suitability probability and the fertilizer score:

Let's say the suitability probability of the plant is 90%. w_s and w_f are 2 weight coefficients.

New Score = (w_s * S) + (w_f * F)

= (0.8 * 0.9) + (0.2 * 0.6667)

≈ 0.85334

The problem here is: To deploy and calculate this score I'm missing The plant nutrients requirements. How to determine the nutrient requirements (needs) of a plant (ex Indian fig, potatoes, ..) in terms of nitrogen (N), phosphorus (P), and potassium (K)... I mean how much nutrients a plant needs on average to grow. I know that the nutrient requirements of a plant can vary depending on factors such as soil fertility, and growth stage, but is there any database or any mathematical model that can model the nutrient requirements of a plant with respect to soil and climatic characteristics?

Note: I'm not a biologist, Just a data science Student. Sorry if the post is too long. I'm open to any biology/math resources and any other inspirations or approaches.

Does anyone know or recommend a safety interval or re-entry period for cupper sulfate pentahydrate?
