The carbon stock in the litter and mineral horizons of loamy and sandy soils turned out to be comparable, except for the sandy soils of mixed forests due to higher clay content. In the course of succession of the coniferous-deciduous forests on the loamy soil, the carbon accumulation in the...
for example sandy or loamy soil, small projections will suffice.问题补充:匿名 2013-05-23 12:21:38 例如沙质或壤质土,小的突起就足够了。 匿名 2013-05-23 12:23:18 例如含沙或沃土的土壤,小投射将足够了。 匿名 2013-05-23 12:24:58 例如含沙或沃土的土壤,小投射将足够了。 匿名 2013...
(1) S1—Sandy-loam soil, low fertility, low useful soil depth, with gravel. (2) S2—Loamy soil, medium fertility, good depth, no gravel. (3) S3—Lime-clayey soil, high fertility, optimal depth, no gravel. (4) Calculated by an interpolation ofDriessen and Konijn (1992)data, with K0...
Plants can't grow well in ___ soil. A. sandy B. clay C. rocky D. loamy 相关知识点: 试题来源: 解析 C。本题考查不同土壤类型对植物生长的影响。sandy soil 沙质土壤,clay soil 黏土,loamy soil 肥沃的壤土,这些土壤在一定条件下植物可以生长。rocky soil 多石的土壤,植物难以生长。反馈...
A. Sandy B. Clayey C. Loamy D. Stony 相关知识点: 试题来源: 解析 C。解析:肥沃的土壤富含养分。loamy soil 是肥沃的土壤,含有适量的沙、黏土和腐殖质,富含养分。sandy soil 沙质土壤排水性好但养分较少。clayey soil 黏质土壤保水性好但透气性差。stony soil 多石的土壤不利于植物扎根生长。反馈...
These soils are mainly composed of sand (greater than 70%) with very little clay (less than 15%) and/or silt. They generally hold low quantities of organic matter. The soil texture is either a sand or loamy sand. Because these soils contain very little clay or organic matter they tend ...
Five soils, which varied in depth to a sandy/loamy boundary, were analyzed for evidences of lithological discontinuity and clay translocation. Four of these soils occurred in close landscape association; the fifth soil, formed in an obviously stratified parent material, was included to test the ...
A. sandy soil B. clay soil C. loamy soil D. all of the above 相关知识点: 试题来源: 解析 D。解析:长且深的根系的植物在沙质(sandy soil)、黏土(clay soil)、壤土(loamy soil)都有可能生长得好。沙质土壤排水性好,黏土保水性强,壤土肥力较好,长而深的根系可以在不同特性的土壤中获取所需...
题目Which soil is easy to work with? A. sandy soil B. clay soil C. loamy soil 相关知识点: 试题来源: 解析 C。loamy soil(壤土)质地适中,容易耕种。sandy soil(沙质土壤)质地松散,容易流失。clay soil(黏土)质地坚硬,难以耕种。反馈 收藏 ...
Sandy soil C. Loamy soil D. Clayey soil 相关知识点: 试题来源: 解析 C。解析:肥沃的土壤适合种蔬菜。loamy soil 肥沃的土壤含有适量的沙、黏土和腐殖质,适合蔬菜生长。stony soil 多石土壤不利于蔬菜生长。sandy soil 沙质土壤保水性差不太适合蔬菜。clayey soil 黏质土壤透气性差也不太适合蔬菜生长。
