Data from: Soil resistance under grazed intermediate wheatgrass

Intermediate wheatgrass [Thinopyrum intermedium (Host) Barkw. & D.R. Dewey subsp. intermedium] is a high-yielding cool-season grass with adaptable uses for grazing, haying, and soil restoration. Despite its adaptability, adoption of intermediate wheatgrass has been limited due to inadequate stand longevity under grazing stress. A study was conducted near Mandan, ND USA to investigate if stand longevity of intermediate wheatgrass was affected by changes in soil properties due to grazing. Soil data from this study included measurements of soil bulk density, soil pH, soil organic carbon, and total soil nitrogen on a Wilton silt loam soil (USDA: Fine-silty, mixed, superactive frigid Pachic Haplustoll). Measurements were made in May 1997 (baseline) and again in May 2004 following four years of grazing. Data may be used to understand soil property responses to grazed perennial forages. Data are generally applicable to rainfed conditions under a semiarid Continental climate for the following associated soil types: Temvik, Grassna, Linton, Mandan, and Williams.

中位小麦草（薄稃羊茅，学名 Thinopyrum intermedium (Host) Barkw. & D.R. Dewey subsp. intermedium）是一种高产量冷季牧草，适用于放牧、割草和土壤恢复。尽管其适应性较强，但由于在放牧压力下植株寿命不足，中位小麦草的推广应用受到限制。在美国北达科他州曼丹附近进行了一项研究，旨在探究中位小麦草的植株寿命是否受到放牧导致的土壤性质变化的影响。该研究土壤数据包括对威灵顿壤土（美国农业部分类：细粘壤土，混合型，超活跃寒冷的Pachic Haplustoll）的土壤容重、土壤pH值、土壤有机碳和总土壤氮的测量。测量分别在1997年5月（基线）和经过四年放牧后的2004年5月进行。这些数据可用于理解放牧多年生牧草对土壤性质的反应。数据通常适用于半干旱大陆性气候下的雨养条件，适用于以下相关土壤类型：特米克、格拉斯纳、林顿、曼丹和威廉姆斯。
