Can we reduce P losses by using new P fertilizers? We are checking it out. Stay tuned in to see the results. @OstaraTech @CG_EfficientP

Listen to the podcast, then check out the #OpenAccess A&EL article by Kleinman, Osmond and team! doi.org/10.1002/ael2.20084 @donflaten1 @NathanONelson @alshober @NPK_Professor @USDA_ARS
Conservation practices move us towards a sustainable planet. But without proper testing and a holistic POV, they can cause unintended consequences or tradeoffs that affect the surrounding environment. Pete Kleinman and Deanna Osmond discuss this puzzle. ow.ly/xH6350Q8yxW

History of Fertilizer 101: It's interesting how world events or even events of one country can affect inputs for agriculture so severely. 3 major world events impacted fertilizer use both positively & negatively and impacted the agricultural practices of our farmers.

Making good progress with our planting at the #KAWfieldlab. With any luck we will get done before dark

Comparing how #conservation practices affect the environment and #farmers’ bottom lines, a @KStateAgron team found that the most profitable system also had the greatest phosphorus and sediment loss: ow.ly/43X250Nz9PR @KraigRoozeboom @KStateSoilH2O 📸: @NathanONelson

Here's a paper that anyone can access on the benefits & potential risks of many widely-recommended conservation practices, written by 15 scientists from across North America. Bottom line: no practice is a cure-all and putting the right practice in the right place is important.

Fertilizer harms soil health? NO! Despite overwhelming data, the myth persists. Global review by Geisseler & Scow on mineral N ferts of 64 long-term trials. N fertilizer=15% INCREASE microbial biomass, 13% INCREASE SOC. Longer time= better. Watch soil pH lnkd.in/ejP8maR6

Excellent example of the interaction between soil properties and soil extractants.
New publication on Kansas soils: Evaluation of Mehlich‐3 for CEC in Kansas soils: M3 in soils with a pH of >7.3 will likely result in overestimation of exchangeable Ca and CEC. acsess.onlinelibrary.wiley.c… @KStateAgron @KStateRE

Every now and then you have to take time off for some fun. I hope you are having a great Christmas and I wish you all a happy new year. youtu.be/mRmoMeUvMxQ via @YouTube

Have you ever wondered why different labs recommend different fertilizer rates from the same soil sample? What data supports their interpretation? A national effort is underway to bring transparency to soil test recs! youtu.be/o9d4hoxFjAY @SlatonNathan @OSU_NPK @USDA_ARS
