📢 New @Econutri30 -related publication!

Research from @ATB_Potsdam examines how poultry housing & manure management affect ammonia emissions.

👏 Congrats to Dr @Wajidumar007, Barbara Amon & team!

What we found:
🇪🇺 Layer systems: 52.7% lower NH₃ EF than North America 🇪🇺 Broiler systems: 43% lower 📉 Post-2010 systems: 54% lower EF than pre-2010
Post-2010 systems: 54% lower EF than pre-2010

Emission factors evolve with housing design and manure management.

[Wajid Umar, PhD @Wajidumar007]

In our new study, we analyzed emission factors across Europe and North America.

How can we choose today the best solutions for tomorrow’s livestock systems?
The NUTRITIVE project assesses the environmental, economic and social impacts of innovative technologies to support more sustainable and resilient management.

The @Econutri30 consortium gathered in Braga 🇵🇹 for a productive General Assembly reviewing progress, sharing results, and planning next steps toward more #sustainable #nutrientmanagement in #agriculture.
💡Great outcomes, strong collaboration & shared vision!

We are four research groups launching a large-scale ag experiment in Negev and Jezreel Valley, 7crops rotation. The project will measure NP biogeo and microbial dynamics. Лooking for a postdocto lead data integration (large data), starting January/ summer 26, for 3 years. repost

🐖 Sawdust bedding: -46% CH₄
💨 Air scrubbers: -24% NH₃
🚜 Slurry scraping: -53% NH₃
🐄 Woodchips + flushing: NH₃ ↓ in cattle barns

[Wajid Umar, PhD @Wajidumar007]

🌍 Livestock housing isn’t just about animal comfort — it’s a key battleground for cutting farm emissions.
Our new Biosystems Engineering study uses the global DATAMAN-Housing database to reveal which barn practices can curb CH₄, N₂O & NH₃.

[NutritiveHorizonEU @NutritiveH_EU]

🌱 First day of the #NutritiveProject in #Turin.
We’re discussing sustainable manure management, EU regulations and innovative tools to support more climate-friendly farming 🌍
#ASAJA #ZeroPollution #SustainableFarming

[NutritiveHorizonEU @NutritiveH_EU]

Everything is ready in Turin!
#NUTRITIVE project assembly is about to start
Over the next two days, partners from across Europe will share progress and challenges on how to improve manure management, protect biodiversity, and meet the 2030 climate goals
#ZeroPollution

[Wajid Umar, PhD @Wajidumar007]

💡 Bonus: Synergies with anaerobic digestion, solid-liquid separation, and policy outlooks.
🧭 Future-ready solutions for farmers, researchers & regulators.

💨 Slurry stinks... and it pollutes. But what if we could flip the script?

🚜 Just published:
“Acidification of animal slurry in housing & storage to reduce NH₃ & GHG emissions — recent advances & future perspectives”

[Wajid Umar, PhD @Wajidumar007]

🧪 We dive into:
🔸 Mineral acids ➡️ tried & tested
🔸 Organic acids & bio-waste ➡️ greener options
🔸 Microbial inoculants ➡️ next-gen solutions
📉 Data-driven review of how much emissions really drop:
✔️ NH₃ ⬇️
✔️ CH₄ & N₂O ⬇️
✔️ Practicality ⬆️

[Wajid Umar, PhD @Wajidumar007]

@Sajjad_Razza -Visualize the different parameters or combinations of parameters in the form of jitter plots/scatter plots.
-Check if the data makes sense keeping in mind the field knowledge. Remove outliers if any.
-Check the data distribution

[Wajid Umar, PhD @Wajidumar007]

@Sajjad_Razza make it normalized using different transformation approaches i.e., log, etc.
I usually fit the model first and then ANOVA.
for mean and confidence intervals I follow the bootstrap approach

[Wajid Umar, PhD @Wajidumar007]

@Sajjad_Razza What I generally do:
Import data
Descriptive statistics:
use the summary() or describe() function to get an overview of data
Check if there are missing values. If yes, we need to see if removing them will impact the result. If yes, we should do the imputation.

[Wajid Umar, PhD @Wajidumar007]

@Sajjad_Razza Good luck Dr. Sajjad
