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: (

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.

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

Nutrient cycling in forests [PDF]

open access: yesNew Phytologist, 1993
SUMMARYStudies of nutrient cycling in forests span more than 100 yr. In earlier years, most attention was given to the measurement of the pools of nutrients in plants and soil and of the return of nutrients from plant to soil in litterfall. The past 20 yr or so have seen a major concentration on the processes of nutrient cycling, with particular ...

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.

Effects of Increased Acidification on Soil Available Cd and Rice

open access: yesGuangdong nongye kexue, 2023
【Objective】The acidification materials were used to intensify soil acidification and the impacts of changes in soil pH on Cd activity in soil and rice yield and quality after acidification of Cd contaminated soil were explored, with a view to providing ...
