This paper identified the dominant protozoan species in the four layers of rhizosphere soil during the six growth stages of . and analyzed the correlations of the abundance and diversity of the dominant protozoan species with soil properties at different growth stages and soil depth. A total of 15 species of protozoa were identified; among them, sp., sp., two kinds of sp., and sp. were the most dominant species of . rhizosphere soil. The sp. was eurytopic species in the . rhizosphere soil and sp., sp., sp., sp.1, and sp. 2 were noted closely related to the acceleration function of circulation of N and P elements in soils. These dominant protozoan species were proposed to play a significant role of fertilization on N supply in rhizosphere soil during the initial growth of .

The remobilization of cadmium (Cd) in contaminated farmland soil due to nitrogen fertilizer addition has raised significant concerns regarding the effectiveness of immobilization remediation. This study investigated the effects of ammonia nitrogen (NH-N) and nitrogen (NO-N) application (100 kg/ha) on the remobilization of immobilization of remediation Cd (bound to clay palygorskite) during various growth stages of rice through field experiments. Our findings revealed that increased organic acid secretion (e.

As farming practices evolve and climate conditions shift, achieving sustainable food production for a growing global population requires innovative strategies to optimize environmentally friendly practices and minimize ecological impacts. Agroecosystems, which integrate agricultural practices with the surrounding environment, play a vital role in maintaining ecological balance and ensuring food security. Rhizosphere management has emerged as a pivotal approach to enhancing crop yields, reducing reliance on synthetic fertilizers, and supporting sustainable agriculture.

Wheat () is grown on more arable acreage than any other food crop and has been well documented to produce allelochemicals. Wheat allelochemicals include numerous benzoxazinoids and their microbially transformed metabolites that actively suppress growth of weed seedlings. Production and subsequent release of these metabolites by commercial wheat cultivars, however, has not yet been targeted by focussed breeding programmes seeking to develop more competitive crops.

is an important medicinal herb; but its long-term cultivation often leads to continuous cropping problems. The underlying cause can be attributed to the accumulation of and alterations in root exudates; which interact with soil-borne pathogens; particularly ; triggering disease outbreaks that severely affect its yield and quality. It is therefore crucial to elucidate the mechanisms by which root exudates induce CCS043 outbreaks.

As an extension of plant root system, arbuscular mycorrhizal fungi (AMF) extraradical mycelium (ERM) can break the limitation of rhizosphere and play an important role in plant nutrient acquisition. However, it remains unclear whether ERM is smart enough to pick out nutrients while avoiding poison, or is unable to pick out nutrients and have to absorb poisons together. Therefore, the present study employed a compartment device to separate the mycelia from roots, aiming to explore the nutrient absorption pathways of mycelia in molybdenum (Mo) pollution soil after inoculation with AMF in maize and vetch plants.
