Effects of long-term organic fertilizer and straw on soil quality and crop yield in a rapeseed-maize rotation system.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study aimed to pursue more sustainable agriculture in a new rapeseed-maize rotation system. We assessed the effects of organic fertilizer and straw on soil quality and crop yield through a 15-year field experiment: mainly applied organic fertilizer (MM); mainly applied inorganic fertilizer with straw (MCS); mainly applied inorganic fertilizer (MC); applied only inorganic fertilizer with straw (CS); and applied only inorganic fertilizer (C) as a control. Compared to the C treatment, crop yields, soil organic carbon (SOC), available nitrogen (AN), phosphorus (AP), potassium (AK), soil porosity (SP), field capacity (FC), and 0.250-2.000 mm large aggregates in soil water-stable aggregates (WA0.250-2.000) were significantly (P<0.05) increased by organic fertilization treatments (MCS, MC, and MM); and soil bulk density (SBD) and WA<0.053 were significantly decreased. Similarly, straw addition (CS and MCS) treatments also had significant effects on soil nutrients, structure, and yield, compared to the C and MC treatments, respectively. However, compared to the MC treatment, applying more organic fertilizers (MM) had no significant effect. The highest nutrient comprehensive evaluation value (NCEV), SP, FC, MA>2.000, WA0.053-0.250, and crop yields were observed in the MCS treatment. Compared to C treatment, rapeseed and maize yield significantly increased by 36.0% and 11.8% in response to MCS treatment, respectively. Pearson correlations showed that total nitrogen (TN), total potassium (TK), AK, SBD, and WA<0.053 were the strongest correlates of crop yields, followed by SOC, FC, WA>2, and WA0.250-2.000. This suggests that MCS was the best fertilization method to increase crop yields by improving SOC, AK, FC, and WA>0.250, and reducing SBD and WA<0.053.
