Silicate Fertilizer Amendment Alters Fungal Communities and Accelerates Soil Organic Matter Decomposition

Frontiers in Microbiology, 2019
Soil microorganisms play a crucial role in organic matter decomposition and nutrient cycling in cropping systems. Compared to bacteria, fungal community composition and the role of fungi in organic matter decomposition and nutrient cycling in agro ...

Organic amendment type and application frequency affect crop yields, soil fertility and microbiome composition

, 2017
Vegetable cultivation under plastic tunnels provides high-quality crop yields but negatively affects soil fertility, especially when conventional agricultural system (e.g., use of synthetic mineral fertilizer and agrochemicals) was adopted.

Fertilizer impacts on soil aggregation and aggregate-associated organic components

Plant, Soil and Environment, 2018
A 5-year (2012-2016) field experiment was conducted to investigate the impacts of different fertilizer treatments (no fertilizer, mineral and organic fertilizer) on organic carbon and soil water-stable aggregates in a North China Plain Vertisol. Compared

Incorporation of Nitrogen-15-Labeled Amendments into Physically Separated Soil Organic Matter Fractions

, 2008
Physically separated soil organic matter (SOM) fractions may take different functions in soil N dynamics. We studied the effect of long-term organic matter (OM) management and different soil biological activity on the incorporation of N added with ...

Sugarcane Yield Response to Furrow-Applied Organic Amendments on Sand Soils

International Journal of Agronomy, 2015
Organic amendments have been shown to increase sugarcane yield on sand soils in Florida. These soils have very low water and nutrient-holding capacities because of the low content of organic matter, silt, and clay.

The Economic Value of Biochar in Crop Production and Carbon Sequestration [PDF]

This paper estimates the economic value of biochar application on agricultural cropland for carbon sequestration and its soil amendment properties. In particular, we consider the carbon emissions avoided when biochar is applied to agricultural soil ...

The role of organic matter amendment level on soil heating, organic acid accumulation, and development of bacterial communities in solarized soil

, 2016
In light of the negative environmental impacts of soil fumigants such as methyl bromide, soil solarization, the treatment of soil using passive solar heating, has emerged as an environmentally friendly approach to soil pest suppression.

How Does Organic Amendment Improve Quinoa Growth and Productivity under Saline Conditions?

, 2022
Nowadays, salinization is becoming a serious problem affecting several agricultural areas, especially irrigated ones. A field experiment was conducted in Foum El Oued, south of Morocco, testing quinoa responses to three irrigation-water salinities (4, 12,

Changes in aggregate-associated carbon pools and chemical composition of topsoil organic matter following crop residue amendment in forms of straw, manure and biochar in a paddy soil

Geoderma
In agricultural ecosystems, incorporation of crop residues has been practiced as a recycling approach for sustaining soil organic matter (SOM) and soil fertility.
