History
Origins
Regenerative agriculture is based on various agricultural and ecological practices, with a particular emphasis on minimal soil disturbance and the practice of composting. Similar ideas focus on "sea minerals." His work led to innovations in no-till practices, such as ''slash and mulch'' in tropical regions.
Sheet mulching is a regenerative agriculture practice that smothers weeds and adds nutrients to the soil below.
In the early 1980s,
the Rodale Institute began using the term ‘regenerative agriculture’.
Rodale Publishing formed the Regenerative Agriculture Association, which began publishing regenerative agriculture books in 1987 and 1988.
However, the institute stopped using the term in the late 1980s, and it only appeared sporadically (in 2005 and 2008), until they released a white paper in 2014, titled "Regenerative Organic Agriculture and Climate Change".
The paper's summary states, "we could sequester more than 100% of current annual
CO2 emissions with a switch to common and inexpensive organic management practices, which we term 'regenerative organic agriculture.'" The paper described agricultural practices, like
crop rotation
Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. This practice reduces the reliance of crops on one set of nutrients, pest and weed pressure, along with the pro ...

In 2002, Storm Cunningham documented the beginning of what he called "restorative agriculture" in his first book, ''The Restoration Economy''. Cunningham defined restorative agriculture as a technique that rebuilds the quantity and quality of topsoil, while also restoring local biodiversity (especially native pollinators) and watershed function. Restorative agriculture was one of the eight sectors of restorative development industries/disciplines in ''The Restoration Economy''.

environmental science, plant science, and
ecology

. As the term expands in use, many books have been published on the topic and several organizations started to promote regenerative agriculture techniques.

gave a TED talk on fighting and reversing climate change in 2013. He also launched The Savory Institute, which educates ranchers on methods of holistic land management. Abe Collins created LandStream to monitor ecosystem performance in regenerative agriculture farms. Eric Toensmeier had a book published on the subject in 2016. However, researchers at Wageningen University in the Netherlands found there to be no consistent definition of what people referencing "regenerative agriculture" meant. They also found that most of the work around this topic were instead the authors' attempt at shaping what regenerative agriculture meant.
In 2011, the (not for profit) Mulloon Institute was founded in New South Wales, Australia, to develop and promote regenerative practices to reclaim land as water-retentive areas by slowing the loss of water from land. The members of the Institute created a 22-weir in-stream project with neighbours over 2 kilometers of Mulloon Creek. A study indicates that the outcomes were positive but relatively unpredictable, and that suitability of ground conditions on site was a key for success. Bottom-up change in the context of Australian regenerative agriculture is a complex set of narratives and barriers to change affecting farmers. A West Australian government funded survey of land hydration was conducted by the Mulloon Institute in June 2022, which concluded that water retention projects supported the regeneration of native plant species.
Founded in 2013, 501(c)3 non-profit Kiss the Ground was one of the first to publicize the term to a broader audience. Today the group runs a series of media, farmland, education, and policy programs to raise awareness around soil health and support farmers who aim to transition from conventional to regenerative land management practices.

. According to the report, regenerative agriculture is already implemented on 15% of all cropland. Despite this, the rate of transition is "far too slow" and must be tripled by the year 2030 to prevent the global temperature passing the threshold of 1.5 degrees above preindustrial levels. Agricultural practices must immediately change in order to avoid the damage that would result. One of the authors emphasised that “The interconnection between human health and planetary health is more evident than ever before.” The authors proposed a set of measures for accelerating the transition, like creating metrics for measuring how much farming is sustainable, and paying farmers who will change their farming practices to more sustainable ones.
Principles
Several individuals, groups, and organizations have attempted to define the principles of regenerative agriculture. In their review of the existing literature on regenerative agriculture, researchers at
Wageningen University
Wageningen University & Research (also known as WUR) is a public university, public research university in Wageningen, Netherlands, specializing in life sciences with a focus on agriculture, technical and engineering subjects. It is a globally i ...
created a database of 279 research articles on regenerative agriculture.
Their analysis of this database found that people using the term regenerative agriculture were using different principles to guide regenerative agriculture efforts.
The 4 most consistent principles were found to be, 1) enhancing and improving soil health, 2) optimization of resource management, 3) alleviation of climate change, and 4) improvement of water quality and availability.
Notable definitions of principles

Rodale Institute, which was one of the first organization to use the term "Regenerative Agriculture".
The principles they've outlined include building soil health and fertility, increase water percolation and retention, increasing biodiversity and ecosystem health, and reducing carbon emissions and current atmospheric CO
2 levels.
The group Terra Genesis International, and VF Corporation's partner in their regenerative agriculture initiative, created a set of 4 principles, which include:
[Soloviev, E. and Landua, G. Levels of Regenerative Agriculture. Terra Genesis International, High Falls, NY, 2016.]

* "Create context-specific designs and make holistic decisions that express the essence of each farm"

Loring argues that, depending on the relative flexibility of people in the food system with respect to the foods they eat and the overall diversity of foods being produced and harvested, food systems can fall into one of four general patterns:
* Regenerative (high diversity, high flexibility), where ecosystems are able to recycle and replenish used energy to usable forms, such as found in many Indigenous food systems
* Degenerative (High diversity, low flexibility), where people fixate on specific resources and only switch to alternatives once the preferred commodity is exhausted, such as

Environmental impacts
Carbon sequestration
Conventional agricultural practices such as plowing and tilling release carbon dioxide (CO
2) from the soil by exposing organic matter to the surface and thus promoting oxidation.
It is estimated that roughly a third of the total anthropogenic inputs of CO
2 to the atmosphere since the industrial revolution have come from the degradation of soil organic matter
and that 30–75% of global soil organic matter has been lost since the advent of tillage-based farming.
Greenhouse gas (GHG) emissions associated with conventional soil and cropping activities represent 13.7% of anthropogenic emissions, or 1.86 Pg-C y
−1.
The raising of ruminant livestock also contributes GHGs, representing 11.6% of anthropogenic emissions, or 1.58 Pg-C y
−1.
Furthermore, runoff and siltation of water bodies associated with conventional farming practices promote eutrophication and emissions of methane.
Regenerative agriculture practices such as no-till farming,

Additionally, 1 Pg-C y

There is mixed evidence on the carbon sequestration potential of regenerative grazing. A meta-analysis of relevant studies between 1972 and 2016 found that Holistic Planned Grazing had no better effect than continuous grazing on plant cover and biomass, although it may have benefited some areas with higher precipitation. However, some studies have found positive impacts compared to conventional grazing. One study found that regenerative grazing management, particularly zadaptive multipaddock (AMP) grazing, has been shown to reduce

.
There is a less developed evidence base comparing regenerative grazing with the absence of livestock on grasslands. Several peer-reviewed studies have found that excluding livestock completely from semi-arid grasslands can lead to significant recovery of vegetation and soil carbon sequestration. A 2021 peer-reviewed paper found that sparsely grazed and natural grasslands account for 80% of the total cumulative carbon sink of the world’s grasslands, whereas managed grasslands (i.e. with greater livestock density) have been a net greenhouse gas source over the past decade. A 2011 study found that multi-paddock grazing of the type endorsed by Savory resulted in more soil carbon sequestration than heavy continuous grazing, but very slightly less soil carbon sequestration than "graze exclosure" (excluding grazing livestock from land). Another peer-reviewed paper found that if current pastureland was restored to its former state as wild grasslands, shrublands, and sparse savannas without livestock this could store an estimated 15.2 - 59.9 Gt additional carbon.
The total carbon sequestration potential of regenerative grazing has been debated between advocates and critics. One study suggests that total conversion of livestock raising to AMP grazing practices coupled with conservation cropping has the potential to convert North American farmlands to a
carbon sink

−1.
Over the next 25–50 years, the cumulative sequestration potential is 30-60 Pg-C. Additions of organic manures and compost further build soil organic carbon, thus contributing to carbon sequestration potential.
However, a study by the Food and Climate Research Network in 2017 estimates that, on the basis of meta-study of the scientific literature, the total global soil carbon sequestration potential from grazing management ranges from 0.3-0.8 Gt CO2eq per year, which is equivalent to offsetting a maximum of 4-11% of current total global livestock emissions, and that “Expansion or intensification in the grazing sector as an approach to sequestering more carbon would lead to substantial increases in methane, nitrous oxide and land use change-induced CO2 emissions”, leading to an overall increase in emissions.
Consistent with this, Project Drawdown (referenced in the film ''Kiss the Ground'') estimates the total carbon sequestration potential of improved managed grazing at 13.72 - 20.92 Gigatons CO2eq between 2020–2050, equal to 0.46-0.70 Gt CO2eq per year. A 2022 peer-reviewed paper estimated the carbon sequestration potential of improved grazing management at a similar level of 0.15-0.70 Gt CO2eq per year.
A research made by
the Rodale institute suggests that a worldwide transition to regenerative agriculture can soak more than 100% of the currently emitted by people.
Nutrient cycling
Soil organic matter is the primary sink of nutrients necessary for plant growth such as nitrogen, phosphorus, zinc, sulfur, and molybdenum.
Conventional tillage-based farming promotes rapid erosion and degradation of soil organic matter, depleting soil of plant nutrients and thus lowering productivity.
Tillage, in conjunction with additions of inorganic fertilizer, also destroys soil microbial communities, reducing production of organic nutrients in soil.
In contrast, use of organic fertilizer will significantly increase the organic matter in the soil.
Practices that restore organic matter may be used to increase the total nutrient load of soil.
For example, regenerative management of ruminant livestock in mixed-crop and grazing agroecosystems has been shown to improve soil nutrient cycling by encouraging the consumption and decomposition of residual crop biomass and promoting the recovery of nitrogen-fixing plant species.
Regenerative crop management practices, namely the use of crop rotation to ensure permanent ground cover, have the potential to increase soil fertility and nutrient levels if nitrogen-fixing crops are included in the rotation.
Crop rotation and rotational grazing also allow the nutrients in soil to recover between growing and grazing periods, thus further enhancing overall nutrient load and cycling.
Soil Microbiome and its role in Nutrient Cycling
The soil microbiome which consist of bacteria, fungi, and other microorganisms play an essential role in nutrient cycling by decomposing organic matter and releasing essential nutrients for plant growth.
Their activities are needed for
decomposition
Decomposition is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is ess ...
and
mineralization processes, which help to transform complex organic compounds into simpler forms that plants can absorb. In nitrogen cycling,

Diazotrophs are organisms capable of nitrogen fixation, i.e. converting the relatively inert diatomic nitrogen (N2) in Earth's atmosphere into bioavailable compound forms such as ammonia. Diazotrophs are typically microorganisms such as bacteria ...

Nitrifying bacteria are chemolithotrophic organisms that include species of genera such as '' Nitrosomonas'', '' Nitrosococcus'', '' Nitrobacter'', '' Nitrospina'', '' Nitrospira'' and '' Nitrococcus''. These bacteria get their energy from the oxi ...
.
While both ammonium and nitrate are important for plant growth, nitrate is the most preferred for many plants due to its mobility, less toxicity, and efficient transport systems. Ammonium is also a great alternative as it is more readily assimilated once inside the plant, it can cause
toxicity
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacteria, bacterium, or plant, as well as the effect o ...
if taken up in excess.
Environmental conditions such as soil pH, and nutrient availability play major roles in determining which form of nitrogen is absorbed first
. Soil microbes also play a key role in
phosphorus cycling, helping to dissolve phosphorus from organic material for plant availability.
A diverse microbial community also helps to prevent
soil-borne diseases and reduces the need for synthetic fertilizers.
Impact of Farming Practices on Nutrient Cycling: Conventional vs Regenerative
Conventional farming
Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of ...
disrupts nutrient cycling by using practices like tillage, which breaks down soil structure, reduces soil organic matter (SOM), and negatively impacts the overall soil health.
Conventional practices lead to reduced crop yields, increased reliance on
synthetic fertilizers, and environmental problems like nutrient runoff and water pollution.
Over-reliance on synthetic fertilizers depletes soil health by favoring the growth of certain microorganisms over others, thereby reducing
microbial diversity, organic matter decomposition, leading to soil degradation.
In contrast, regenerative agriculture promotes practices that enhance soil health and nutrient cycling.
These practices include reduced tillage which helps to preserve SOM, the use of
organic fertilizers such as compost for soil enrichment, incorporating regenerative livestock management, practicing crop rotation with leguminous plants like soybean to promote nitrogen fixation that occurs from the
symbiotic relationship
Symbiosis (Ancient Greek : living with, companionship < : together; and ''bíōsis'': living) is any type of a close and long-term biolo ...
between nitrogen-fixing bacteria and the root nodules.
Integrating livestock into cropping systems has been shown to improve nutrient cycling as animal manure enriches the soil and promotes microbial diversity.
Cover crop
In agriculture, cover crops are plants that are planted to ground cover, cover the soil rather than for the purpose of being harvested. Cover crops manage soil erosion, soil fertility, soil quality, water, weeds, Pest (organism), pests, diseases ...
ping is another practice that helps to prevent erosion, leading to healthier and more resilient soils.
Biodiversity
Conventional agricultural practices are generally understood to simplify agroecosystems through introduction of monocultures and eradication of diversity in soil microbial communities through chemical fertilization.
In natural ecosystems, biodiversity serves to regulate ecosystem function internally, but under conventional agricultural systems, such control is lost and requires increasing levels of external, anthropogenic input.
By contrast, regenerative agriculture practices including polycultures, mixed crop rotation, cover cropping, organic soil management, and low- or no-tillage methods have been shown to increase overall species diversity while reducing pest population densities.
Additionally, practices that favor organic over inorganic inputs aid in restoring below-ground biodiversity by enhancing the functioning of soil microbial communities.
A survey of organic and conventional farms in Europe found that on the whole, species across several taxa were higher in richness and/or abundance on organic farms compared to conventional ones, especially species whose populations have been demonstrably harmed as a direct result of conventional agriculture.
AMP grazing can help improve biodiversity since increased soil organic carbon stocks also promotes a diversity of soil microbial communities.
Implementation of AMP in North American prairies, for example, has been correlated with an increase in forage productivity and the restoration of plant species that had previously been decimated by continuous grazing practices.
Furthermore, studies of arid and semiarid regions of the world where regenerative grazing has been practiced for a long time following prior periods of continuous grazing have shown a recovery of biodiversity, grass species, and pollinator species.
Furthermore, crop diversification ensures that the agroecosystem remains productive when facing lower levels of soil fertility. Higher levels of plant diversity led to increases in numerous factors that contribute to soil fertility, such as soil N, K, Ca, Mg, and C, in CEC and in soil pH.

Criticism
Some members of the scientific community have criticized some of the claims made by proponents of regenerative agriculture as exaggerated and unsupported by evidence.

One of the prominent proponents of regenerative agriculture,

"it is not possible to increase productivity, increase numbers of cattle and store carbon using any grazing strategy, never-mind Holistic Management ..Long term studies on the effect of grazing on soil carbon storage have been done before, and the results are not promising. ..Because of the complex nature of carbon storage in soils, increasing global temperature, risk of desertification

from livestock, it is unlikely that Holistic Management, or any management technique, can reverse climate change."
Commenting on his TED talk "How to Fight Desertification and Reverse Climate Change", Savory has since denied claiming that holistic grazing can reverse climate change, saying that “I have only used the words address climate change… although I have written and talked about reversing man-made desertification”.
Savory has faced criticisms for claiming the carbon sequestration potential of holistic grazing is immune from empirical scientific study.
For instance, in 2000, Savory said that "the scientific method never discovers anything" and “the scientific method protects us from cranks like me". A 2017 factsheet authored by Savory stated that “Every study of holistic planned grazing that has been done has provided results that are rejected by range scientists because there was no replication!". TABLE Debates sums this up by saying "Savory argues that standardisation, replication, and therefore experimental testing of HPG
olistic Planned Grazingas a whole (rather than just the grazing system associated with it) is not possible, and that therefore, it is incapable of study by experimental science", but "he does not explain how HPG can make causal knowledge claims with regards to combating desertification and climate mitigation, without recourse to science demonstrating such connections."
According to a 2016 study published by the
Swedish University of Agricultural Sciences
The Swedish University of Agricultural Sciences, or Swedish Agricultural University (, SLU) is a public research university in Sweden. Although its main campus and head office is located in Ultuna, Uppsala, the university has several campuses ...
, the actual rate at which improved grazing management could contribute to carbon sequestration is seven times lower than the claims made by Savory. The study concludes that holistic management cannot reverse climate change. A study by the Food and Climate Research Network in 2017 concluded that Savory's claims about carbon sequestration are "unrealistic" and very different from those issued by peer-reviewed studies.
Tim Searchinger and Janet Ranganathan have expressed concerns about emphasis upon "Practices That Increase Soil Carbon at the Field Level" because "overestimating potential soil carbon gains could undermine efforts to advance effective climate mitigation in the agriculture sector." Instead Tim Searchinger and Janet Ranganathan say, "preserving the huge, existing reservoirs of vegetative and soil carbon in the world’s remaining forests and woody savannas by boosting productivity on existing agricultural land (a land sparing strategy) is the largest, potential climate mitigation prize of regenerative and other agricultural practices. Realizing these benefits requires implementing practices in ways that boost productivity and then linking those gains to governance and finance to protect natural ecosystems. In short, produce, protect and prosper are the most important opportunities for agriculture."
