Athletic fields often use sand‐based root zones for improved drainage. Sand‐based root zones may have stability issues if turfgrass is not fully established. Our objective was to use organic amendments to improve the stability of sand‐based fields during the turfgrass establishment period and avoid overuse of inorganic materials, which have negative effects. Coconut coir, peat, or wheat (Triticum aestivum L.) straw at 1% organic material, peat at 2% organic material, and an inorganic stabilizing fiber, StaLok were tested, in the top 10 cm of the root zone of a Kentucky bluegrass (Poa pratensis L.) playing surface. In addition, rates of wheat straw, up to 2.5% organic matter were tested. Surface hardness (G_max), volumetric water content, traction, penetration resistance, and visual quality were measured 2–4 mo after construction of the plots. Surface hardness was greatest in the inorganic stabilizer (51.7–61.7 g) and the wheat straw treatments (49.7–55.9 g). The kinetic penetration had no differences between the wheat straw (33.78–51.10 kPa) and the StaLok fibers (34.99–56.23 kPa). The results showed that it was possible to use up to 2% straw to increase the resistance to deformation and increase soil moisture while keeping acceptable visual quality and the surface hardness below 80 g. The organic matter from straw degraded faster than peat and after 4 mo of the growing season <1.5% remained. Wheat straw could be used to stabilize sand‐based fields as an organic alternative to inorganic fibers.

在草皮草建立期间使用有机改良剂来稳定沙质运动场

运动场通常使用基于沙子的根部区域来改善排水。如果草皮草未完全建立，则基于沙子的根部区域可能存在稳定性问题。我们的目标是在草皮草建立期间使用有机改良剂来改善砂基田地的稳定性，并避免过度使用无机材料，这会带来负面影响。椰棕，泥炭，或小麦（小麦属）稻草在1％的有机材料，泥炭在2％的有机材料和无机稳定纤维，StaLok进行了测试，在顶部10cm的草地早熟禾的根区的（Poa pratensis L.）打面。此外，还测试了麦秸，有机物含量高达2.5％的比例。表面硬度（G _max），在绘制地块后2-4个月测量了体积水含量，牵引力，抗穿透性和视觉质量。在无机稳定剂（51.7–61.7 g）和麦秸处理（49.7–55.9 g）中，表面硬度最大。小麦秸秆（33.78–51.10 kPa）和StaLok纤维（34.99–56.23 kPa）之间的动力学渗透率没有差异。结果表明，可以使用高达2％的秸秆来提高抗变形能力和增加土壤湿度，同时保持可接受的视觉质量和80 g以下的表面硬度。秸秆中的有机物降解速度快于泥炭，并且在生长季节的4个月后仍＜1.5％。小麦秸秆可作为无机纤维的有机替代品，用于稳定沙田。
