Spatial variability of soil physicochemical properties in soybean wheat belts in Vertisols of central India.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Inappropriate land management and fertilizer application may lead to nutrient deficiency soil degradation in the long run. The soil degradation in terms of changes in soil physical and chemical properties is the main impairment of crop productivity. Therefore, management practices based on soil spatial variability are now inevitable for enhancing agricultural productivity, food safety, and environmental modelling. The present study conducted to characterize the field-scale spatial variability of soil physical (sand, silt, clay, water content at field capacity (FC), and permanent wilting point (PWP), mean weight diameter (MWD)) and soil chemical properties (pH, EC, soil organic carbon (SOC), available phosphorous (Av-P), and available potassium (Av-K)) in soybean-wheat belts in Vertisols of central India. These belts are intensively cultivated and followed the uniform management practices without considering soil spatial variability. A total of 260 geocoded soil surface (0-20 cm) samples were randomly collected from the study area. The values of soil pH, EC, SOC, Av-P, Av-K, sand, silt, clay, FC water content, PWP water content and MWD varied from 6.09 to 8.56, 0.04 to 0.43 dS m
