Jena Soil Model (JSM v1.0; revision 1934): a microbial soil organic carbon model integrated with nitrogen and phosphorus processes [PDF]

open access: yes, 2020
Plant–soil interactions, such as the coupling of plants' below-ground biomass allocation with soil organic matter (SOM) decomposition, nutrient release and plant uptake, are essential to understand the response of carbon (C) cycling to global changes ...

Biofilms for babies: introducing microbes and biofilms to preschool-aged children [PDF]

open access: yes, 2017
Microbes are beneficial to life on our planet as they facilitate natural processes such as global nutrient cycling in our environment. This article details a 30-minute activity to introduce pre-school children ranging from 3 to 5 years of age to microbes

Carbon and nutrient losses during manure storage under traditional and improved practices in smallholder crop-livestock systems - evidence from Kenya [PDF]

open access: yes, 2009
In the absence of mineral fertiliser, animal manure may be the only nutrient resource available to smallholder farmers in Africa, and manure is often the main input of C to the soil when crop residues are removed from the fields.

Effects of different regimes of fertilization on soil organic matter under conventional tillage

open access: yesSpanish Journal of Agricultural Research, 2014
To explore the effects of different fertilization regimes on soil organic matter (SOM) sequestration in a winter-soybean/corn rotation, a long-term field experiment was conducted in Anhui, China, from 1982 to 2011. There were six treatments, as follows: (

Effects of Phosphorus on Nitrification Process in a Fertile Soil Amended with Urea

open access: yesAgriculture, 2021
While the effects of carbon on soil nitrogen (N) cycle have been extensively studied, it is not clearly understood how co-existing macronutrients, such as phosphorus (P), affect the N cycle in agroecosystems.

Impact of biological manure substitution on grain yield, nitrogen recovery efficiency, and soil biochemical properties [PDF]

open access: yesPeerJ
Fertilization plays a crucial role in ensuring global food security and ecological balance. This study investigated the impact of substituting innovative biological manure for chemical fertilization on rice (Oryza sativa L) productivity and soil ...

The effect of different post-exercise beverages with food on ad libitum fluid recovery, nutrient provision, and subsequent athletic performance [PDF]

open access: yes, 2019
This study investigated the effect of consuming either water or a carbohydrate (CHO)-electrolyte sports beverage (‘Sports Drink’) ad libitum with food during a 4 h post-exercise recovery period on fluid restoration, nutrient provision and subsequent ...

The Effects of Intraspecific Variation of Crayfish Behavior on Nutrient Cycling in Aquatic Environments [PDF]

open access: yes, 2020
Human activities are rapidly altering species traits at a global scale. Yet, there remains a critical need to determine whether trait variation within species affects ecosystem responses to global change. In particular, intraspecific variation in feeding

Long-term straw incorporation benefits the elevation of soil phosphorus availability and use efficiency in the agroecosystem

open access: yesSpanish Journal of Agricultural Research, 2018
Soil pH and organic matter are important factors influencing phosphorus (P) fertilizer use efficiency. Long-term crop straw incorporation alters soil pH and soil organic matter.

Blended controlled-release nitrogen fertilizer increases rice post-anthesis nitrogen accumulation, translocation and nitrogen-use efficiency

open access: yesFrontiers in Plant Science
One-time application of blended controlled-release nitrogen fertilizer (CRN) has the potential to solve the difficulty of top-dressing fertilizer in the cultivation of rice and reduce the cost of CRN fertilizer application.
