“…The wide variation in concentration of nutrients in the study area is ascribed to different parent materials, prevailing climatic conditions, and natural and anthropogenic activities. Our findings are in line with the results reported by Patel et al (2015) who recorded the available status of micronutrients, that is, Fe, Zn, Mo and S in the soils of central India, which ranged at 30-8,253, 0·7-5·0, 0·1-8·9 and 41-747 mg kg À1 with mean value of 642 AE 186, 2·3 AE 0·2, 1·5 AE 0·3 and 281 AE 25 mg kg À1 , respectively. Shukla et al (2016) also reported mean values of 1·66, 1·37, 10·30 and 12·20 mg kg À1 for available Zn, Cu, Mn and Fe, respectively, in soils of intensively cultivated Trans-Gangetic Plains of India.…”

Agricultural land degradation due to nutrient deficiencies is a threat to agricultural sustainability. As nutrients availability is influenced by soil heterogeneity, climatic conditions and anthropogenic activities; hence, delineation of nutrient management zones (MZs) based on spatial variability could be an effective management option at regional scale. Thus, the present study was carried out to delineate MZs in the Shiwalik Himalayan region of India by capturing spatial variability of soil properties and secondary and micronutrients status because of the emerging nutrient deficiencies. For the study, a total of 2575 geo‐referenced representative surface (0–15 cm depth) soil samples were collected from the study region covering an area of 53,483 km2. The soils were analysed for pH, electrical conductivity, soil organic carbon, available sulphur (S) and micronutrients (Zn, Fe, Cu, Mn, B and Mo) concentrations. There was a wide variation in soil properties with coefficient of variation values of 14 (for pH) to 86% for available Mo. Geostatistical analysis revealed spherical, Gaussian, exponential, stable, circular and K‐Bessel best‐fit models for soil properties. Most of the soil properties were having moderate spatial dependence except soil pH and S (strong spatial dependence) and Zn (weak spatial dependence). About 49%, 10%, 2%, 13%, 11%, 12% and 8% area of the study region were found to be deficient (including acute and marginal deficiency) in S, Zn, Fe, Cu, Mn, B and Mo, respectively. The principal component analysis and fuzzy c‐mean clustering were performed to develop the MZs. Four principal components with eigenvalues greater than 1 and accounting 65·4% of total variance were retained for further analysis. On the basis of fuzzy performance index and normalized classification entropy, four potential MZs were identified. Analysis of variance confirmed the heterogeneity in most of the studied soil properties among the MZs. The study indicated that the methodology of delineating MZs can be effectively used in site‐specific S and micronutrients management in the Shiwalik Himalayan region of India.

“…EC, K, and Fe were positively correlated whereas correlation was negative with Mn at P = 0.01. The correlation between EC, Zn, and Cu at these levels were not significant (Patel et al, ). Corwin and Lesch () opined that soil EC is an indirect indicator of salinity levels and nutrient availability in soils.…”

“…This indicated wide spread deficiency of Zn, Cu, and Fe (Figure g–j). The micronutrient contents were found several folds lesser than in central India and Trans‐gangetic plains (Patel et al, ). High variability existed for micronutrients with CV ranging from 65.0 to 121.…”

Soil mapping and delineation of management zones in the Western Ghats of coastal India

The pace of land degradation has almost doubled across the Western Ghats of India, one of the world's ‘hotspots’ for biodiversity, owing to soil erosion, mining, and rampant urbanization. The arising nutrient depletion leading to land degradation is thus a serious threat to agricultural sustainability in this region. Delineation of spatial soil property maps for nutrient management is an effective strategy for precision agriculture. The present investigation was carried out in North Goa District in Western Ghats, a seldom researched domain in the Indian coastal region. The study involved spatial array analysis of soil properties of 383 georeferenced soil samples and used fuzzy k‐means clustering for delineation of management zones (MZs). Soils were found highly acidic with low available N, P, and medium exchangeable K with a widespread Zn, Cu, and Fe deficiency and sporadic salinity. Soil properties exhibited low to high levels of skewness except for soil pH and Mn. Correlations between soil pH and K, Zn, and Mn, between EC and Fe, between soil organic carbon (SOC) and N, P, K, Cu, and Mn was positive and significant (P = 0.01). Geostatistical analysis revealed varied distribution pattern for soil properties with Gaussian (pH, P, and Cu), spherical (EC), stable (SOC), hole effect (N), K‐Bessel (K and Fe), exponential (Zn), and circular (Mn) as best fit semivariogram models with weak and strong spatial dependence. The spatial variability was mapped, and two MZs were delineated. The developed maps will be crucial in site‐specific nutrient management for agricultural and ecological sustainability in the Western Ghats of India.
