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
