摘要

2021-22 年期间,对安得拉邦普拉卡萨姆地区受盐碱影响地区的土壤特性和土地利用情况进行了评估。研究人员在受盐业影响的村庄共采集了 240 份土壤样本,并对其进行了不同物理、物理化学性质的分析。土壤的 pH2 值在 7.2-11.0 之间,ECe 值在 0.3-58.0 dSm-1 之间,ESP 值在 0.9-57.0 之间,CEC 值在 3.5-56.6 c mol (p+) kg-1 之间。 盐碱地、盐碱土和碱土等问题土壤存在于不同的土地利用方式中。共对 460 名受盐影响地区的农民和 460 名非盐影响地区的农民进行了生计选择研究。农民们正通过奶牛、绵羊和山羊养殖、农林业、散养家禽、果园、树木产品(树叶、树干、果实)等多种方式实现生计多样化,如利用盐渍土中的主要本地植被制煤、烧柴,以确保他们的收入,维持生计。

Soil Properties and Land Use in Salt Affected Soils of Prakasam District, Andhra Pradesh, India P
A study was conducted to assess the soil properties, land use in salt affected areas of Prakasam district,Andhra Pradesh during 2021-22. A total of 240 soil samples in salt affected mandals were collected and were analysed for different physical, physico-chemical properties. The sandy clay loam texture is predominant (35.90%) followed by sandy loam (28.21%).  pH2 of soil varied from 7.2-11.0, ECe ranged from 0.3-58.0 dSm-1 ESP ranged from 0.9-57.0, CEC ranged from 3.5-56.6 c mol (p+) kg-1.  The problem soils namely saline, saline alkali and alkali are present under various land use. A total of 460 farmers in salt affected areas and 460 farmers in non salt affected areaswere studied for livelihood options. The farmers are diversifying the livelihoods by practicing dairy, sheep and goat farming, Agroforestry, backyard poultry, orchards, products (leaf, trunk, fruits)of  trees for various other purposes like coal preparation, firewood by utilizing  predominant native vegetation in salt affected soils to secure their income for sustaining livelihoods.
