土壤-作物环境中的养分缺乏和管理不当是世界各地作物产量低、农产品营养质量下降和动物/人类营养不良的重要原因。本研究旨在评估印度农业土壤中硫（S）和微量元素[锌（Zn）、硼（B）、铁（Fe）、铜（Cu）和锰（Mn）]的营养缺乏情况，以制定有效的管理策略，实现可持续的作物生产，提高作物的营养质量，改善动物/人类健康。从印度28个邦的615个地区的农田中收集了2,42,827个表层（0-15厘米深）土壤样品，并对有效硫和微量营养素浓度进行了分析。这项研究是在全印度土壤和植物中微量和次生营养素及污染元素协调研究项目的主持下进行的。有效硫的平均浓度为27.0 ± 29.9 mg kg−1，有效锌为1.40 ± 1.60 mg kg−1，有效B为1.40 ± 4.70 mg kg−1，有效铁为31.0 ± 52.2 mg kg−1，有效铜为2.30 ± 3.50 mg kg−1，有效锰为17.5 ± 21.4 mg kg−1。在不同的州，硫和微量营养素的缺乏是可变的和普遍的。土壤中S（58.6%）、Zn（51.2%）和B（44.7%）的缺乏（急性缺乏+缺乏+潜在缺乏）高于Fe（19.2%）、Cu（11.4%）和Mn（17.4%）。在615个区中，有效硫、有效锌和有效B不足的区分别有101、131和86个，不足率均在50%以上。有效铁、有效铜和有效锰含量不足的地区分别有83个、5个和41个，不足率均在25%以上。2种营养素如S + Zn缺乏的情况时有发生（9.30%土壤），Zn + B（8.70%的土壤），S + B（土壤的7.00%）和Zn + Fe（5.80%的土壤）在更大程度上相比，缺乏锌+锰土壤中硫+铁（3.30%）、锌+铜（2.80%）和铁+ B（2.70%）。土壤中3种养分（S + Zn + B、S + Zn + B和Zn + Fe + B）、4种养分（Zn + Fe + Cu + Mn）和5种养分（Zn + Fe + Cu + Mn + B）同时缺乏的比例较低。有关硫和微量营养素（单一和多种营养素）缺乏分布的信息可供各利益攸关方用于在印度不同地区，州和农业生态区域生产，供应和应用正确类型的肥料，以提高作物产量，作物营养质量，养分利用效率，土壤健康以及解决人类和动物营养不良问题。
Nutrient deficiencies in soil–crop contexts and inappropriate managements are the important reasons for low crop productivity, reduced nutritional quality of agricultural produce and animal/human malnutrition, across the world. The present investigation was carried out to evaluate nutrient deficiencies of sulphur (S) and micronutrients [zinc (Zn), boron (B), iron (Fe), copper (Cu) and manganese (Mn)] in agricultural soils of India for devising effective management strategies to achieve sustainable crop production, improved nutritional quality in crops and better animal/human health. A total of 2,42,827 surface (0–15 cm depth) soil samples were collected from agriculture fields of 615 districts lying in 28 states of India and were analysed for available S and micronutrients concentration. The study was carried out under the aegis of All India Coordinated Research Project on Micro- and Secondary-Nutrients and Pollutant Elements in Soils and Plants. The mean concentrations were 27.0 ± 29.9 mg kg−1 for available S, 1.40 ± 1.60 mg kg−1 for available Zn and 1.40 ± 4.70 mg kg−1 for available B, 31.0 ± 52.2 mg kg−1 for available Fe, 2.30 ± 3.50 mg kg−1 for available Cu and 17.5 ± 21.4 mg kg−1 for available Mn. There were variable and widespread deficiencies of S and micronutrients in different states. The deficiencies (acute deficient + deficient + latent deficiency) of S (58.6% of soils), Zn (51.2% of soils) and B (44.7% of soils) were higher compared to the deficiencies of Fe (19.2% of soils), Cu (11.4% of soils) and Mn (17.4% of soils). Out of 615 districts, > 50% of soils in 101, 131 and 86 districts were deficient in available S, available Zn and available B, respectively. Whereas, > 25% of soils in 83, 5 and 41 districts had deficiencies of available Fe, available Cu and available Mn, respectively. There were occurrences of 2-nutrients deficiencies such S + Zn (9.30% of soils), Zn + B (8.70% of soils), S + B (7.00% of soils) and Zn + Fe (5.80% of soils) to a greater extent compared to the deficiencies of Zn + Mn (3.40% of soils), S + Fe (3.30% of soils), Zn + Cu (2.80% of soils) and Fe + B (2.70% of soils). Relatively lower % of soils were deficient in 3-nutrients (namely S + Zn + B, S + Zn + B and Zn + Fe + B), 4-nutrients (namely Zn + Fe + Cu + Mn) and 5-nutrients (namely Zn + Fe + Cu + Mn + B) simultaneously. The information regarding the distribution of deficiencies of S and micronutrients (both single and multi-nutrients) could be used by various stakeholders for production, supply and application of right kind of fertilizers in different districts, states and agro-ecological regions of India for better crop production, crop nutritional quality, nutrient use efficiency, soil health and for tackling human and animal malnutrition.
