土壤保持是经常涉及到与风蚀、水蚀有关的主要的土地退化活动.土壤保持是一个较为广泛的问题.不仅关系到主要侵蚀活动,而且也关系到影响着土壤肥力总体保持的较为缓慢的、连续不断的隐伏过程.土壤紧实,土壤有机质、土壤养分含量和微生物活动能力减少,都是土壤保持专家应予关心的问题.土壤保持往往被认为是用以防止土地退化的一些技术,缺乏农学知识的土木工程师经常持己看法,而又使这种看法得以强化.对农民来说土壤保持会被认为是不可理解、不适合当地条件的不必要的花费.在国际土壤研究与管理委员会的观点看来.土壤保持是土壤管理实践能力维持方面的一部分,既无需破坏表土地上层.还要与耕作制度相结合及适宜生境的特性.土壤保持问题涉及国际土壤研究与管理委员会(IBSRAMS)的三个主要目标,首先是关于以供养农业为目的的热带土地的开垦.另一方面还涉及酸性带土壤管理和森林土壤的管理.
Soil conservation is a major land degradation activity often associated with wind erosion and water erosion, and soil conservation is a broader issue not only related to major erosion activities but also to the slower and more continuous impacts affecting the overall maintenance of soil fertility Constantly concealed processes Soil compaction, soil organic matter, soil nutrient content and reduced microbial activity are all issues that soil conservation experts should be concerned with. Soil conservation is often considered as a technique that is used to prevent land degradation and lacks agronomic knowledge Of civil engineers often give their own views, but also make this view strengthened.For farmers, soil conservation will be considered incomprehensible, not suitable for local conditions, unnecessary costs.In the International Soil Research and Management Committee point of view Soil conservation is part of the maintenance of practical soil management practices that do not require damage to the upper and upper soil layers but also to the tillage system and the characteristics of the habitat that are suitable for the soil conservation issues that involve three of IBSRAMS The main goal, first of all, is about tropical lands for the purpose of supporting agriculture Reclamation on the other hand also involves acid zone soil management and forest soil management.
