Over the past years, standard land use and industrial farming practices have caused a decrease in land suitable for food production. Instead of creating soil that’s rich in nutrients, these practices reduce soil fertility.
A growing population and climate related-shocks threaten agricultural productivity due to ongoing land subdivisions and soil degradation as a result of overgrazing, over-cropping, erosion and poor farming methods.
One potential way to reverse the negative effects of industrial agriculture is a system of agricultural principles called regenerative farming. Regenerative farming involves farming practices that rejuvenate soil health.
The following regenerative agricultural practices aim to improve the well-being of our environment by increasing soil fertility, biodiversity, water retention and cleanliness, and soil carbon sequestration.
Cover crops and crop rotation are two of basic principles of sustainable agriculture that lead to greater biodiversity. In this, farmers plant cover crops with no intention of harvesting them in order to protect the soil. Without cover crops, soil is vulnerable to weather erosion, which causes beneficial nutrients to dry out and wash away or blow away.
Additionally farmers should rotate crops by growing a different type of crop in the same location each growing season. This ensures that nitrogen-fixing plants like legumes can add nutrients to the soil that other plants absorb.
Creating healthy soil is one of the predominant goals of regenerative agriculture, and decreasing tilling is one of the best regenerative practices for improving soil. Tilling simultaneously causes soil erosion and releases substantial amounts of carbon dioxide into the atmosphere. Eliminating tillage increases carbon sequestration—a process where plants transfer carbon from the air into the soil—and helps reduce global warming.
Synthetic fertilizer is not conducive to regenerative systems because it creates an imbalance of microbes in soil, impeding the natural processes by which plants absorb nutrients. This results in an agroecosystem with weak plants that become dependent on artificial fertilizer.
In addition, artificial fertilizer worsens the climate crisis due to the negative effects of chemicals seeping into water sources and the atmosphere. In general, a regenerative farming system aims to preserve a completely natural relationship between plants and soil organisms.
According to research by Research Gate, mulching has demonstrated efficacy to enhance soil health by reducing evaporation, increasing moisture retention, regulating temperature, enhancing nutrient availability and root absorption, suppressing weeds, decreasing salinity, encouraging biological activity, and controlling crop pests and diseases.
Farmers are advised to use organic plant mulch such as cowpea, bracharia grass and leguminous. For non-living organic mulches can be. rice or wheat straw, and palm. Additionally, animal residues from poultry, pig, goat, horse and cow dung can also be used.
Such organic mulching serves to protect the bare soil by building organic matter, conserving moisture, retaining nutrients, minimizing erosion and suppressing weeds.
“The continued use of synthetic products has caused soil degradation. This has in turn to the zero biological actions in the soil hence, poor crop performance and increased crop diseases. The only approach to restore the soil back to its productive nature is regenerative farming,” Fred Munene
“Pesticide-resistant superweeds, combined with the climate & biodiversity crises, are threatening the food supply we rely on to survive. We cannot delay the shift to organic and ecologically regenerative agriculture any longer.” Friends Of The Earth
Regenerative agriculture has become the darling of many policymakers, food companies and farmers. Advocates claim a triple win: climate change mitigation, increased profit for farmers and greater resilience to a changing climate. Our view is that the practices grouped as regenerative agriculture can improve soil health and food production.
