Study on the dynamics of phosphorus adsorption and the risk of release in black soils by conservation tillage.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In this experiment, the adsorption characteristics and release risk of phosphorus from three types of soils-namely no-tillage with straw off the field (CK), no-tillage with straw crushed and mulched (FS), and no-tillage with straw high-stubble mulched (GH), were investigated using a batch experimental method. The data showed that the adsorption of phosphorus was divided into three stages and reached equilibrium at 480 min. Compared with CK, FS and GH treatments reduced phosphorus adsorption by 14.68% and 24.63%, respectively. The highest adsorption occurred at pH 7, and the adsorption of phosphorus by the soil gradually decreased with increasing nitrogen concentration. Correlation analysis of soil physicochemical properties and adsorption characteristics showed that the maximum adsorption of phosphorus (Qmax) was significantly negatively correlated with the available nitrogen (AN) and positively correlated with the pH value. The environmental risk index (ERI) followed the order to GH > FS > CK, with physicochemical interactions contributing 87.13% to phosphorus adsorption. Comprehensive analysis concluded that straw return decreased the soil's phosphorus adsorption capacity, enhanced phosphorus availability, but increased the risk of phosphorus release. Appropriately increasing soil pH and reducing nitrogen fertilizer application can enhance phosphorus adsorption.
