The node represents an element. An element node can have the following child node types: Element, Text, Comment, ProcessingInstruction, CDATASection, and EntityReference. An element node can be the child of the Document, DocumentFragment, EntityReference, and Element nodes.
Replacement Costs. Although costs vary according to the size of the leach field, soils and costs of local permits, expect to pay between $5,000 and $20,000 for leach field replacement.It is the most expensive component of the septic system.eplacement Costs.

This example is for applying 80 pounds of nitrogen per acre. As you can see from the output, only at the lower nitrogen use efficiencies and/or the higher costs of nitrogen per pound do you lose money fertilizing grass hayfields. The table illustrates a number of possible scenarios where inputs such as cost per pound of actual nitrogen in the fertilizer, nitrogen use efficiency (lbs of additional forage per lb of N applied), value of hay per ton, cost of harvesting the additional hay produced, and cost of fertilizer application must be considered.
