However, intensive farming practices have degraded soil ecosystems. Organic amendments and regenerative management practices can restore soil function by overcoming nutritional limitations, improving physical and biological properties, and promoting general soil and crop resilience. This review synthesizes research on major sources of organic soil amendments including animal manures, composts, cover crops, crop residues and living mulches. We describe their multifaceted edaphic and agronomic benefits from providing a slow release bank of macro and micronutrients, increasing soil organic matter, and stimulating beneficial microbial communities. Complementary and synergistic soil building practices are also covered, encompassing conservation tillage techniques like no-till, crop diversification via rotations and intercropping, and agroecological integration of trees and livestock. Although transitioning from degraded conventional systems requires patience as years of soil regeneration are needed to enable high system performance, outcomes consistently show integrated practices that minimize disturbance and maintain living ground cover while leveraging organic inputs can transform the foundation of agricultural systems by enhancing soil ecosystem function. Widespread adoption of this soil health paradigm can thereby enable sustainable intensification and resilience.

These benefits range from increasing soil carbon storage, boosting soil fertility, to transforming and fixing pollutants in soil, all of which serve to ameliorate the overall soil environment. The impact of these improvements extends to the metabolic activities and community structure of soil microorganisms, either directly or indirectly, creating ripple effects on soil health. This paper embarks on a thorough review of biochar's effects on various soil aspects. These include the soil's physicochemical properties, such as its structure, composition, and reaction properties, and how biochar can influence these to improve the soil environment. It also explores how biochar affects enzyme activities in the soil that are crucial for various biochemical processes, as well as nutrients vital for p...

Biochar is baked biomass that you can add to soil. It is a biomass that is thermally altered in the absence of oxygen, it is baked and not burned and flammable gasses are released (hydrogen, carbon dioxide). Heat transforms plant carbon (found in the cellulose and lignin) into fused aromatic carbon rings that are very stable. Biochar are made from different feedstocks at different physical and chemical properties. In carbon cycle almost all of the carbon returns to the air. Green plants remove carbon dioxide from the atmosphere via photosynthesis and convert it into biomass. Virtually all of that carbon is returned to the atmosphere when the plants die and decay, or immediately if the biomass is burned as a renewable substitute for the fossil fuels. While in the biochar cycle up to half of the carbon is sequestered, green plants removed and sequestered as biochar, while the other half is converted to renewable energy co- products before being returned to the atmosphere. Biochar retains soil moisture of the agricultural field. Worms loves biochar, it works best when composted with other organic matter before adding to garden soil. This allows life to colonize the biochar. Biochar composted with animal manure, it is inoculated with compost tea. Biochar composted with food waste and bokashi (anaerobic lactobacillus fermentation). Other activities include minerals, NPK, fungi, worm castings, fish emulsion, urea, etc. biochar can be added to soils to improve fertility. Reduces emissions from the biomass. Improves the water quality and quantity. Helps to improve the agricultural productivity. Valuable resource reduces the forest fires. Value added product for urban and rural agriculture and forest communities.
