Abstract

Soil testing for physical and chemical characteristics of a soil is key in assessment of a soil fertility that leads to productivity of a soil. A total of 11231 soil samples from six tehsils of Attock district were collected during five years (2012-17). Samples were analyzed for different parameters like pH, EC (1:10), texture, organic matter, Olsen Phosphorus and NH4-acetate extractable Potassium. As regards pH, 98% samples ranged between 7.5-8.5 while 97% samples were normal with respect to salinity/sodicity (ECe<4 dSm and SAR<15). Similarly 22% samples were light and 78% were medium in texture. Soils (96% ) were poor in organic matter (<0.86%) while 99% had available phosphorus <7 mg kg. 1362 soil samples were also analyzed for potassium showing poor in 31% samples (<80 mg kg ) while 69% samples lie in satisfactory to adequate range (81-180 mg kg). Depending upon the soil analysis, farmers were guided for fertilizer recommendations according to climate suitability, crop/orchard/vegetable and water/rainfall conditions as being implemented throughout the rain fed conditions of the Punjab by the Directorate of Soil Fertility, Thokar Niaz Beg, Lahore.

短通讯:阿托克地区的土壤特征

土壤物理和化学特性的土壤测试是评估土壤肥力的关键，从而导致土壤的生产力。2012- 2017年5年间，在阿托克区6个县共采集土壤样品11231份。对样品进行pH、EC(1:10)、质地、有机质、Olsen磷和nh4 -乙酸盐可提取钾等参数的分析。在pH值方面，98%的样品在7.5-8.5之间，而97%的样品在盐度/碱度方面正常(ECe<4 dSm, SAR<15)。同样，22%的样品质地较轻，78%的样品质地中等。96%土壤有机质含量较低(<0.86%)，99%土壤速效磷含量<7 mg kg。1362份土壤样品的钾含量分析显示，31%的样品(<80 mg kg)钾含量较差，69%的样品在81 ~ 180 mg kg的范围内。根据土壤分析，由拉合尔Thokar Niaz Beg土壤肥力局根据气候适宜性、作物/果园/蔬菜和水/降雨条件指导农民进行肥料建议，并在旁遮普邦的整个雨养条件下实施。
