  采样前要详细了解采样地区的土壤类型、肥力等级和地形等因素，将测土配方施肥区域划分为若干个采样单元，每个采样单元的土壤要尽可能均匀一致


• 
  采样点数量：采样点的多少，取决于采样单元的大小、土壤肥力的一致性等，一般7-20个点为宜。


• 
  采样路线：采样时应沿着一定的线路，按照“随机”、“等量”和“多点混合”的原则进行采样，一般采用S形布点采样，也可采用梅花形布点取样


• 
  采样方法：采样点的分布应尽量照顾土壤的全面情况，不要太集中，不要在路旁、沟边、渠道附近和粪堆底等地采样，因为这些地方不代表地块的平均肥力。采样时，在采样点上先刮去1厘米左右的表层土，再用取土器或铁铲垂直取深度20厘米，宽10厘米，厚2厘米的土片，取土器应垂直于地面入土，深度相同。用取土铲取样应先铲出一个耕层断面，再平行于断面下铲取土；微量元素则需要用不锈钢取土器采样。然后把各采样点采到的土样在地头摊放在塑料布上，捏碎大块，捡掉砾石、动植物残体等混合物，充分拌匀，便成为混合土样。


• 
  样品重量：一个混和土样以取土1公斤左右为宜，如果样品数量太多，可用四分法将多余的土壤弃去。方法是将采集的土壤样品放在盘子里或塑料布上，弄碎、混匀，铺成四方形，划对角线将土样分成四份，把对角的两份分别合并成一份，保留一份，弃去一份。如果所得的样品依然很多，可再用四分法处理，直至所需数量为止


• 
  样品标记：采集的样品放入统一的样品袋，写好标签，内外各具一张。写明编号，采样地块名称，采样日期，采样人等有关事项
