This article explores farm compost as a method to improve the sustainability of farms by increasing soil qualities – physical, chemical and biological. Increasing the soil quality could equate to higher and better quality yield; the former is much easier to quantify and is a metric in this study.

A deeper look at the relationship between root carbon pools and the vertical distribution of the soil carbon pool (2017)

Authors: Dietzel, R., Liebman, M., & Archontoulis, S.

Publication Details: Soil, 3(3), 139–152.

Executive Summary/Abstract

There was a significant loss of SOC in prairie soils after changing from prairie grasses to annually tilled crops. The root architecture and distribution of perennial and annual plants differ significantly. Results from other studies do not align rooting habits with SOC found at depths. The greatest amount of soil C is found below 0.2m depth, and only a small amount of plant roots are found below this level. After considering climatic and geological influences, the correlation between the C to N ratio (C:N) and the accumulation of SOC in the soil profile may significantly affect the outcome. By investigating the land use change and managing for a return to prairie grasses, it is possible to find out the correlation between the C:N and SOC accumulation.

Evaluation of the Foliar Application of Nano Urea on the Performance of Rabi Sunflower (Helianthus annuus L.) (2022)

Authors: Goud, G., Sudhakar, K., Pasha, M., & Madhavi, A.

Publication Details: International Journal of Environment and ClimateChange, 12(11), 2700-2706.

Executive Summary/ Abstract Nitrogen (N) fertiliser is essential for the quality and quantity of proteins and yields in oil seeds. Assessing appropriate N rates as a top dressing for gaining greater quality and quantity is challenging. Nanotechnology enables understanding and managing N-fertiliser foliar applications to increase quality and yield whilst reducing costs to the farmer.

Organic carbon and nitrogen accumulation in orchard soil with organic fertilization and cover crop management: A global meta-analysis (2022)

Authors: Hu, Y., Zhan, P., Thomas, B. W., Zhao, J., Zhang, X., Yan,H., Zhang, Z., Chen, S., Shi, X., & Zhang, Y.

Publication Details: The Science of the Total Environment, 852, 158402–158402.

Executive Summary/Abstract

Tillage, herbicide use and bare soil are a feature of many orchard systems (olives, citrus, apples, grapes), leading to a decline in SOC. Livestock manure, compost, and cover crops are a way to reduce SOC losses as well as fertilising and managing the crop. This study is a meta-analysis investigating practice change and SOC and STN stock changes.

Annual and perennial crop composition impacts on soil carbon and nitrogen dynamics at two different depths (2022)

Authors: Means, M., Crews, T., & Souza, L.

Publication Details: Renewable Agriculture and Food Systems, 37(5),437-444.

Executive Summary/Abstract 

It is understood that tillage influences the fluxes of N and C in the soil. To reduce the effects of tillage, some farmers have turned to perennial grain crops such as Kernza. There is little information about how these crops affect N and S in the soil.

Net effect of liming on soil organic carbon stocks: A review (2015)

Authors: Paradelo, R., Virto, I., & Chenu, C.

Publication Details: Agriculture, Ecosystems & Environment, 202, 98–107.

Executive Summary/Abstract

Lime is used to correct the pH in the soil to increase plant growth potential. The addition of lime has several effects on soil health. Some of these effects either increase or decrease SOC stocks: an increase in SOC resulting from higher plant productivity, a decrease in SOC stocks resulting from increased organic matter mineralisation, and an increase in SOC stocks due to improved soil physical attributes. These effects do not affect SOC stocks equally. This paper explores the net change of SOC stocks with these factors in mind.

Below ground carbon inputs to soil via root biomass and rhizodeposition of field-grown maize and wheat at harvest are independent of net primary productivity (2018)

Authors: Hirte, J., Leifeld, J., Abvien, S.,Oberholzer, H. & Mayer,J.

Publication Details: Agriculture, Ecosystems and Environment 265, 556-56

Executive Summary/Abstract 

Below-ground carbon inputs comprise 30 – 90% of organic carbon inputs in the soil and have a longer residency time than crop residues above the surface. The two origins of these below-ground inputs are root biomass and rhizodeposition. Most studies into this process do not account for the whole life cycle of the plant.

Remineralizing soils? The agricultural usage of silicate rock powders: A review (2022)

Authors: Swoboda, P., Döring, T. F. & Hamer, M.

Publication Details: The Science of the Total Environment, 807(Pt 3),150976–150976.

Executive Summary/Abstract

In tropical climates, soil nutrient depletion and the cost of fertilisers are limiting factors to growing food crops. Both macro and micronutrients are difficult to afford and access and are highly leachable when added to tropical soils. Finely ground silicate rock powders may be one solution. As a slow-release fertiliser and soil ameliorant, this solution has mixed reviews regarding its effectiveness. This article aims to delve deeper into the factors influencing its success and notable benefits.

Deep soil inventories reveal that impacts of cover crops and compost on soil carbon sequestration differ in surface and subsurface soils (2019)

Publication Details: Global Change Biology, 25(11), 3753–3766.

Executive Summary/Abstract 

Studies in cover cropping, compost and manure additions and perennial crops and pastures mostly report increases in SOC. Broad assumptions in research have been made as to the depth to which these management practices influence SOC.

Jumpstart of soil organic matter with highly stabilized organic amendment: Implicationsfor climate-smart agriculture (2023)


Tian, G., Chiu, C.-Y., Oladeji, O., Johnston, T., Morgan, B., Cox, A., Granato, T., Zhang, H., & Podczerwinski, E.

Publication Details:

Environmental Challenges (Amsterdam, Netherlands), 12, 100726-.

Executive Summary/Abstract 

Alternatives need to be investigated to enhance crop performance and reduce the need for chemical fertiliser. Aged and stabilised compost and/or biosolids are a possible alternative. These alternatives have yield and soil health benefits that buffer soil and crop the effects of climate variability and severity with the bonus of reducing fertiliser needs, emissions, and sequestering carbon.

Does cover crop grazing damage soils and reduce crop yields? (2020)

Authors: Blanco‐Canqui, H., Drewnoski, M. E., MacDonald, J. C., Redfearn, D. D., Parsons, J., Lesoing, G. W., & Williams, T.

Publication Details: Agrosystems, Geosciences & Environment, 3(1).

Executive Summary/Abstract

It is understood that continuous grazing on pastures leads to pasture and soil health declines. If other grazing methodologies affect pasture and soil health differently, can the same be reported for cover crop grazing? How do grazing cover crops and the resultant reduced ground cover affect the capacity of the cover crop to reduce erosion and other soil capacities? Is there a net benefit for the biomass from the cover crops and the dung and urine returned to the soil? What is the net benefit for soil health and increased soil C obtained from roots remaining in the soil?

Grazing cover crops in continuous corn production in east-central Mississippi (2023)

Authors: Rushing, B., Waddell, K., Lyles, J., and Lemus, R.

Publication Details: Agronomy Journal, 115(4), 1653–1665.

Executive Summary/Abstract 

Cover crops can be designed for quality forage for grazing animals in low-growth periods (especially in cold and wet conditions). Cover crops can enhance soil health (increases in SOC and Nitrogen). Combining designed cover crops for forage and soil health could increase the productivity of the farming system by stacking functions without reducing the yield of commodity crops.

Integrating Winter annual forages into a no-till corn silage system (2009)

Authors: Faé, G., Sulc, R., Barker, D., Dick, R., Eastridge, M., & Lorenz, N.

Publication Details: Agronomy Journal, 101(5), 1286–1296.

Executive Summary/Abstract 

It is understood that 30-50% of the SOC pool in the U.S. has been depleted. To replenish this loss, it has been recommended for cropping to implement no-tillage and incorporate winter cover crops to increase the ecosystem services that come with increasing and mitigating SOC losses. Adoption of these practices has been limited primarily due to a lack of economic incentive to implement and possibly change of management difficulties.
