@agronomistag Not in Texas!

[Katie L. Lewis @TxSoilFert]

Fun time talking #carbon at #TNLA Expo.

[Katie L. Lewis @TxSoilFert]

@sverett Where are the girls???

[Katie L. Lewis @TxSoilFert]

@LegallyFarming @dane_berggren Nothing is important if farmers can’t make a living. Very few farmers have the goal of high yields… it’s much more about profitable production.

[Katie L. Lewis @TxSoilFert]

This picture demonstrates that water savings by a cover crop is not enough to offset the water usage by the cover crop prior to termination. A team of scientists are working hard to find the best regenerative cotton practices. #regencotton #NIFAimpacts

@RyanSpeer2 @LegallyFarming Where are you all located?

[Katie L. Lewis @TxSoilFert]

@LegallyFarming This is dryland. We are dependent on rainfall.

[Katie L. Lewis @TxSoilFert]

@FullingSteve 2-4 weeks prior to planting cotton.

[Katie L. Lewis @TxSoilFert]

@ajackag13 This was part of a termination timing study. Termination ranged from 2 to 8 weeks prior to planting cotton. We cannot produce the amount of biomass needed to retain ground cover throughout a growing season. Also, with more biomass comes great water usage. Welcome to West Texas.

[Katie L. Lewis @TxSoilFert]

@ridgeba58592652 Unfortunately this seems like common sense, but it is not. The question is being asked and the concept being pushed constantly.

[Katie L. Lewis @TxSoilFert]

@Sk_Musfiq This was a termination timing study with termination ranging from 2 weeks to 8 weeks prior to cotton planting. The problem is the variability in rainfall since this is dryland production.

[Katie L. Lewis @TxSoilFert]

@forefrontagTX Hey Jeff! Can you explain the science of the product?

[Katie L. Lewis @TxSoilFert]

Great day soil sampling in Martin County, TX. We are working hard to determine baseline soil organic carbon levels across TX. #TexasCorn #sorghum #Cotton @OrinRomine

[Katie L. Lewis @TxSoilFert]

If you want to enhance #SoilHealth health and #carbon capture and storage, make sure to ensure sufficient #nitrogen in available. Optimized #nitrogen = Max #SOC.

[Rob Mikkelsen @RobSoil]

“Right” #Nitrogen Rate is critical for building soil organic carbon (SOC)
@hpoffenb shows (~15yr study) insufficient N fertilization does NOT promote maximum SOC accumulation; excess N does not either. Max #SOC when OPTIMAL N rate used. #4R wins again.

@hofffarms @Jamestanbug The keyword is in “large quantities”. You can over apply water and have negative effects on microbes adapted to an aerobic environment. Applied according to the label using #4Rs, soil health or microorganisms will not be negatively impacted.

[Katie L. Lewis @TxSoilFert]

@Michael72540562 @Jamestanbug @LSimonAGRON If managed correctly, there is no concern. Fertilizer is like any other product, it cannot be over applied and not be expected to have effects.

[Katie L. Lewis @TxSoilFert]

Important to remember.. #nitrogen #fertilizer build soil organic #carbon!! If we remove #inorganic #nitrogen from our production systems, there will be negative effects on #SoilHealth

[Rob Mikkelsen @RobSoil]

What?... #nitrogen #fertilizer BUILDS soil organic matter? Thoughtful review paper reports 3 long-term studies (158 years!) showing N fertilizer builds soil organic carbon. Must maintain proper soil pH & good #4R practices. Read here: https://t.co/Thes042zG1
