Abstract
The present investigation was carried out to assess and map the fertility status of chronically drought affected Tatrakallu village in Anantapuramu district of Andhra Pradesh using GIS and GPS. Two hundred fifty geo-referenced surface soil samples (0-15 cm) from Tatrakallu village located in Scarce Rainfall Zone of Andhra Pradesh were collected at 250 m grid interval and analyzed for their fertility parameters. Analytical data was interpreted and statistical parameters like range, mean, standard deviation and coefficient of variation were calculated. Soil fertility maps were prepared for each parameter under GIS environment using Arc GIS v 10.3. Soils were neutral to strongly alkaline (6.49-8.90) in reaction, non-saline (0.01-0.84 dS m-1) and low to medium (0.3-7.0 g kg-1) in organic carbon. The soils were low to medium in available nitrogen (13-266 kg ha-1) and low to high in available phosphorus (2.0-91.0 kg P2O5 ha-1) and available potassium (0.4-628 kg K2O ha-1) and deficient to sufficient in available sulphur (0.1-50.1 mg kg-1). The wide variation from deficient to sufficient was observed in the status of DTPA extractable zinc (0.1-5.6 mg kg-1), iron (0.8-30.7 mg kg-1) and manganese (1.4-39.0 mg kg-1), whereas DTPA extractable copper (0.2-2.7 mg kg-1) was almost sufficient. The fertility status in Tatakallu village revealed that available N, S, Zn and Fe are important soil fertility constraints.
本调查旨在利用GIS和GPS评估和绘制安得拉邦Anantapuramu区长期干旱影响的Tatrakallu村的生育状况。以250 m网格间隔从安得拉邦Scarce降雨区的Tatrakallu村采集了250个地理参考表层土壤样本(0-15 cm),并对其肥力参数进行了分析。对分析数据进行了解释,并计算了范围、平均值、标准差和变异系数等统计参数。使用Arc GIS v 10.3为GIS环境下的每个参数绘制土壤肥力图。土壤在反应中为中性至强碱性(6.49-8.90),无盐(0.01-0.84dSm-1),有机碳含量为低至中等(0.3-7.0 g kg-1)。土壤的有效氮(13-266 kg ha-1)从低到中等,有效磷(2.0-91.0 kg P2O5 ha-1)和有效钾(0.4-628 kg K2O ha-1)由低到高,有效硫(0.1-50.1 mg kg-1)不足到充足。在DTPA可提取的锌(0.1-5.6 mg kg-1)、铁(0.8-30.7 mg kg-1。Tatakallu村的土壤肥力状况表明,有效氮、硫、锌和铁是土壤肥力的重要制约因素。
