Role of organic matter in soil pH change in agro-ecosystems. Over 50 million hectares of arable lands in Australia are affected by soil acidity. Acidity-affected lands continue to expand due to the ongoing process of acidification under current farming practices. The project will provide new knowledge essential for the improved use and management of organic matter to minimize or reverse soil acidification and increase carbon sequestration in farming systems. The associated reduction of soil aci ....Role of organic matter in soil pH change in agro-ecosystems. Over 50 million hectares of arable lands in Australia are affected by soil acidity. Acidity-affected lands continue to expand due to the ongoing process of acidification under current farming practices. The project will provide new knowledge essential for the improved use and management of organic matter to minimize or reverse soil acidification and increase carbon sequestration in farming systems. The associated reduction of soil acidification will also minimise the negative impact of nutrient and water losses on the environment. Growers will benefit from the project through improved soil fertility and crop production, and sustainable land use. Read moreRead less
