2024年10月18日 · Soil phosphorus (P) directly impacts major sustainability outcomes, namely crop yields, water quality, and carbon sequestration. Optimally managing P to improve sustainability outcomes requires a mechanistic understanding of P availability and transfer, alongside high-resolution spatial data.

2023年2月1日 · Phosphorus (P) fertilizer input influences crop yield, soil P cycling, and phosphate-solubilizing microorganism (PSM) communities, which play a key role in obtaining soil available phosphorus. However, the responses of soil P cycle genes and PSM communities to long-term high-P fertilizer application are less known in the Chinese Loess Plateau.

2021年9月1日 · We predict that microbial N and P cycle potential will differ between the fertilizer treatments and across the soil aggregate size fractions. In particular, the addition of organic material amendments was shown to increase microbial diversity and enhance the genetic potential for N and P cycling.

The Phosphorus Cycle is the biogeochemical cycle that describes the transformation and translocation of phosphorus in soil, water, and living and dead organic material. Phosphorus additions to soil occur due to additions of inorganic and organic (manure) fertilizer and the degradation and decomposition of organic (plant and animal) material.

This study showed that high-P fertilizer input increased the abundance of soil functional microorganisms and soil C cycle genes but decreased the abundance of soil P cycle genes and altered functional genes and microorganisms.

2016年1月1日 · Phosphorus is mostly concentrated near the topsoil partly because of P fertilizer use in cultivated soil, and biological cycling and deposition in leaf‐fall and litter in uncultivated soil, and partly a consequence of its low mobility and high reactivity with soil colloids.

4 天之前 · Understanding the biogeochemical cycling of phosphorus (P), particularly organic P (OP) in soils, under varying land use and soil development processes is essential for optimizing P usage under P fertilizer crisis. However, the complexity of OP impedes the mechanistic understanding. Therefore, by using well-documented organic carbon (OC) and total nitrogen (TN) cycling, we studied their ...

cycling in the soil. Phosphorus cycle is unique and different from the nitrogen cycle because phosphorus does not exist in a gaseous form. This document provides basic information on the various forms of phosphorus present in the soil and the processes that affect phosphorus availability for crop production. Phosphorus Forms Present in the Soil

phosphorus (P) cycle. Understanding the P cycle can help producers make decisions regarding P management on the farm, both for farm profitability and protection of the environment. Most plants are only about 0.2% P by weight, but that small amount is critically important. Phosphorus is an essential component of adenosine triphosphate (ATP ...

2024年12月21日 · In this post, we dive into what the phosphorus cycle is, its steps and stages, its importance, and how human actions are reshaping this critical nutrient cycle. Understanding the phosphorus cycle helps us manage soils sustainably and address global challenges like food security and environmental degradation.
