This month, the dramatic #FarmersProtests in the Netherlands have captured the media's attention.
Today, we take a look at what the coverage got wrong about the #boerenprotest and the #BigAg interests many journalists failed to mention.👇 1/19

#Nitrogen air pollution is a significant issue for UK woods. According to the #StateOfWoodsAndTrees report 100% of woodlands in England exceed the nitrogen critical load – all will have deteriorated as a result.

Bushy grey beard #lichens were once far more abundant, but are sensitive to #AirQuality. They act as miniature forests on trunks and branches, where invertebrates live and birds forage. They’ve also been found to have anti-growth effects on human cancer cells!

@MollyRCain @pkumar3691 @IMLCZO @IUONeillSchool @IUImpact FAVORITE FIGURE IN THE PAPER:
Interacting 'top down' (antecedent soil moisture) and 'bottom up' (GW level) control the sources, ages, and N loads in water mobilized from tile-drained landscapes.

@MollyRCain @pkumar3691 @IMLCZO @IUONeillSchool @IUImpact What controls C-Q dynamics in tile drains? Event size and antecedent conditions (in this case, if the groundwater table was high enough to have the tile flowing with pre-event water when the storm hit)
Models project that #ocean #phytoplankton will become increasingly starved of #nitrogen as #climatechange progresses.
If realised, this has implications for #fisheries.
But how can we monitor this change in the real ocean?
Nitrogen isotopes!

What are nitrogen (N) isotopes?
There is a heavy isotope (15-N) and a light isotope (14-N).
Some processes prefer to use 14-N more than 15-N. When phytoplankton use nitrogen, they prefer 14-N.
This increases the ratio of 15-N to 14-N in seawater.

This increases the ratio of 15-N to 14-N in seawater.
But when N is scarce, phytoplankton have less preference.
Like if there was only one kind of pizza at a party, you don't have the option of being picky (you have to have the pineapple).
In this case, phytoplankton no longer increase the ratio of 15-N to 14-N in seawater.

Listening to Mark Sutton @UK_CEH explain the issues:
“The scaling up of nitrogen happened, and it got cheaper, which has meant people aren’t as careful with it as they should be. Everybody has an opportunity to manage nitrogen more responsibly”

Vijay Kumar talks about his work with over 1m farmers in Andhra Pradesh, India, reducing synthetic #nitrogen & other inputs. Women farmers often lead the work, influencing 1 farmer at a time.
Results? Better health of soil, people & crops.
Inspiring in scale, approach & impact.

The #Crop #Diversity #Experiment funded by @snf_ch can show first results available on @biorxivpreprint. First year results from #Switzerland show 21% and 44% increases in yield in 2- and 4-species #mixtures, respectively. Yield benefits in Spain were 3% and 13%. (1/5)
In a first study we can show that these yield benefits of #intercropping are not due to reduced #weed pressure. Weed abundance was related to crop yield, but not affected by crop #richness, but rather by the presence of #cereals (2/)

A second study shows that increased crop yield in mixtures is both related to positive #sampling effects of tall species and positive #complementarity effects through more efficient #nitrogen use
