A replicated experiment compared bird use, soil structure, grass wear and free-moving nematode populations in 4 different soil media (recycled vegetable compost, 90% recycled vegetable compost and 10% sand, re-used topsoil and sterilised topsoil) all with established grass swards within the range area of a large free-range laying hen unit. 2. The birds initially spent a greater proportion of their time on the two topsoil swards in comparison to the two compost-based swards. However, once the whole flock of hens had prolonged access to the different swards (unfenced areas) there were no significant differences in the number of birds that frequented the different sward types. 3. The two compost-based soil media had 33% fewer nematodes per g of dry soil compared to the two topsoil-based media. However, the rate of loss of grass from the subplots was greater with the two compost-based soil media; this was probably due to the greater porosity of these types of soil media.

一项重复实验比较了4种不同土壤介质（回收蔬菜堆肥、90%回收蔬菜堆肥与10%沙子、再利用表土和消毒表土）上鸟类的使用情况、土壤结构、草皮磨损和自由活动线虫种群，所有这些土壤介质上均有已长成草皮，位于一个大型散养蛋鸡场的范围内。2. 与两种基于堆肥的草皮相比，鸟类最初在两种表土草皮上花费的时间比例更大。然而，一旦整群母鸡能够长时间接触不同的草皮（无围栏区域），光顾不同草皮类型的鸟类数量就没有显著差异。3. 与两种基于表土的介质相比，两种基于堆肥的土壤介质每克干土中的线虫数量少33%。然而，两种基于堆肥的土壤介质的小区草皮损失率更高；这可能是由于这些类型的土壤介质孔隙率更大。
