separated  from  the  untreated  organic  stock  and 
excluded  for  a  certain  period  of  time, eg.  at least  3 
weeks  from  the  date  of  organic  certification.  The 
main  reason  for  veterinary  treatment  in  organic 
animal  husbandry  is  to  study  the  causes  (or 
contributing factors) of diseases in order to enhance 
the animal's natural defense mechanisms (and prevent 
their  occurrence  in  the  future).  Unlike  crop 
production,  synthetics  are  allowed  to  treat  sick 
animals  if  alternative  treatments  are  not  enough. 
Here,  reducing  the  suffering  of  the  animal  is 
prioritized over the elimination of chemicals. 
3  RESULTS AND DISCUSSIONS  
Soil health is a particular focus of narratives related 
to regenerative agriculture. Indeed, the idea that soil 
and soil life in particular is under threat is at the heart 
of most, if not all, calls for regenerative agriculture. 
However,  the  term  "soil  health"  is  inherently 
problematic.  Just  like  soil  quality,  soil  health  is  a 
container concept that  needs to  be  disaggregated  to 
make  sense.  While  this  can  be  seen  as  something 
positive  to  strive  for,  the  basic  soil  functions  need 
meaningful  indicators  that  can  be  measured  and 
tracked over a long period of time. Moreover, cultural 
practices that benefit one aspect of soil health (eg, soil 
life) often have a negative impact on other functions; 
there  is  usually  not one  direction  in soil  health,  but 
several  trade-offs  (Reynard,  2020).  Many  websites 
and  testimonials  about  regenerative  agriculture 
emphasize the importance of soil biodiversity and in 
particular  the  macro-  and  micro-organisms  that  are 
responsible  for  the  biological  cycling  of  nutrients. 
Reports  of  reduced  soil  biodiversity  with  intensive 
farming and the simplification of soil food webs have 
raised  widespread  concerns  about  soil  health.  For 
example, a recent advisory body report to the Dutch 
government  was  ambiguously  titled,  as  the  word 
"bodem"  means  both  bottom  and  soil.  The  report 
argues  that  the  quality  of  the  soil  has  declined  to  a 
critical point - at least in part due to the loss of soil 
biodiversity.  While  research  clearly  identifies 
differences  in  soil  food  webs  between  cultivated 
fields,  pastures,  and  (semi-)natural  vegetation,  the 
relationship with  soil function  is largely  established 
through  correlation—there  is  little  evidence  of  any 
direct  causal  relationship  between  soil  biodiversity 
and  soil  biodiversity.  any  loss  of  function.  .  The 
mantra "feed the soil, not the crop" has long been 
central to organic agriculture, while the importance of 
creating soil organic matter has been emphasized by 
proponents of organic or biodynamic agriculture, as 
well as in more traditional agricultural discourses in 
the  US  and  elsewhere  (Meckling,  2020).  Soil  takes 
centuries to form, and significant loss of soil through 
erosion is unsustainable. The dust bowl of the 1930s 
in the United States became a seminal experience for 
both scientific and public acceptance of the soil. It is 
commonly stated that a quarter or more of the earth's 
soils  are  degraded,  although  exact  numbers  are 
disputed.  Commonly  cited  estimates  of  soil  loss  by 
erosion  are  made  using  runoff  plots,  which  tend  to 
overestimate  the  rate  of  loss  because  they  do  not 
account for the deposition and transport of soil across 
the landscape. However, assume that the rate of soil 
loss exceeds the rate of soil formation by an order of 
magnitude,  assuming  that  a  third  of  the  soils  for 
which data were available have a lifespan of less than 
200  years.  A  related  long-term  trend  drawing 
attention  to  soils  is  the  decline  in  the  global  soil 
carbon pool and its contribution to global warming. 
Recent modeling estimates the historical loss of soil 
carbon  due  to  human  land  use  at  about  116  pg  of 
carbon,  comparable  to  about  one-fifth  of  industry's 
total greenhouse gas emissions. Most of these losses 
are due to changes in land use. Conversion of natural 
vegetation,  especially  forests,  almost  always  results 
in a decrease in SOM content due to non-permanent 
vegetation, removal of biomass and, consequently, a 
decrease in organic matter input. However, the loss of 
soil carbon from land-use conversion is different from 
the  losses  or  benefits  that  can  be  achieved  by 
changing  management  practices  on  existing 
agricultural land (Hibbard, 2019). 
Supporters  of  regenerative  agriculture  attribute 
the  biodiversity  crisis  to  the  widespread  use  of 
monocultures  along  with  heavy  dependence  on 
external  resources  and  the  absence  of  "biological 
cyclicity".  Undoubtedly,  large  areas  of  genetically 
homogeneous crops can be subject to the rapid spread 
of  pests  and  diseases  and  do  little  to  improve  the 
quality  of  rural  landscapes.  If  we  consider 
biodiversity  in  a  broader  sense,  there  is  little  doubt 
that  the  Earth  has  entered  its  sixth  mass  extinction. 
The increase in population, the clearing of primordial 
habitat and the expansion of agriculture over the last 
century are clearly the root causes. How best to halt 
this  loss  of  biodiversity  is  less  clear.  Optimistic 
projections  suggest  that  the  world's  population  will 
peak at 9.8 billion in 2060, while the United Nations 
Population  Program  predicts  a  population  of  11.4 
billion  by  the  end  of  the  century.  In  any  case, 
population  growth  will  undoubtedly  require  the 
production  of  additional  nutritious  foods.  Moderate 
consumption patterns and dietary change can reduce 
this demand, as can food loss and waste, but the most
