项目摘要
Disturbed and degraded lands often have one physical or chemical limitation to productivity that must be
overcome if they are to be restored to pre-disturbance conditions. Their ability to hold onto nutrients as
indicated by their cation exchange capacity (CEC) and their ability to hold onto water to ensure a continuous
supply to the crop is often limited. One way to overcome these limitations is through the addition of soil
amendments especially those of organic origin such as animal manures and crop residue. In several of the areas
where these disturbed lands exist, manure is not available and other organic amendments must be sourced to
restore the land. Alfalfa pellet is made from dehydrated alfalfa by Western Alfalfa Milling Company Ltd.
(WAMCO), a North America's leader in alfalfa pellet production for feed. Alfalfa pellet is a multi-purpose
material that can provide vital nutrients and organic matter, possesses water retention properties and can help
alleviate soil compaction and aeration issues. CEC is an important soil property that influences plant nutrient
storage and uptake. Several studies have shown increases in CEC following animal manure application. To our
knowledge, no previous study has examined the effect of alfalfa pellets and rates on soil CEC. One important
physical property of soil that greatly affects productivity is water retention. The plant available water capacity
of a soil can be estimated from soil water retention at field capacity (FC) and at permanent wilting point
(PWP). Soil water retention is largely influenced by increases in soil organic matter. Manure has been known
to improve soil water retention. If alfalfa pellets are to serve as an alternative organic amendment for land
reclamation, they must have a demonstrated influence on the water retention and cation exchange capacity of
the soil. Therefore the objectives of this study are to determine the effect of different rates of alfalfa pellets on
the CEC and water retention capacity of a sandy soil and a clay soil. Knowledge of the effect of alfalfa pellets
on these soil properties will provide valuable information for WAMCO on the potential of these pellets to
serve as an organic amendment thereby increasing their range of use and market potential.
受干扰和退化的土地往往对生产力有一种物理或化学限制,必须加以解决。
如果要恢复到扰动前的状态,它们吸收营养的能力
通过它们的阳离子交换容量(CEC)和它们保持水以确保连续的
对作物的供应通常是有限的。克服这些限制的一种方法是通过添加土壤
改良剂,特别是有机来源的改良剂,如动物粪便和作物残渣。在一些地区,
在这些受干扰的土地存在的地方,没有粪肥,必须寻找其他有机添加物,
恢复土地。苜蓿颗粒是由西方苜蓿碾磨有限公司以脱水苜蓿为原料制成的。
(WAMCO)是北美饲料用苜蓿颗粒生产的领导者。苜蓿颗粒是一种多用途的
一种可以提供重要营养物质和有机物质的材料,具有保水性,可以帮助
减轻土壤压实和通气问题。CEC是影响植物养分的重要土壤性质
储存和吸收。几项研究表明,施用动物粪便后CEC增加。对我们
知识,没有以前的研究已经检查了苜蓿颗粒和率对土壤CEC的影响。一个重要
土壤的物理性质对生产力有很大影响的是保水性。植物有效水容量
根据田间持水量(FC)和永久萎蔫点的土壤持水量,可以估算土壤的持水量
(PWP)。土壤有机质的增加在很大程度上影响土壤持水能力。肥料已经被人们所知
提高土壤保水能力。如果苜蓿颗粒作为土地的替代有机改良剂
填海,他们必须有一个显着的影响,对水的保留和阳离子交换能力,
土壤。因此,本研究的目的是确定不同比例的苜蓿颗粒对
桑迪和粘土CEC和持水能力。了解苜蓿颗粒的作用
将为WAMCO提供关于这些颗粒的潜力的宝贵信息,
作为有机补充剂,从而增加其使用范围和市场潜力。
