The use of conservation tillage systems can increase infiltration and water movement into and below the root zone. However, conservation tillage can also lead to compaction in some soils and reduced water-holding capacity. If soil compaction is managed, then improved infiltration can provide more water for crop use. The use of conservation tillage systems does not require that irrigation equipment be changed. Conversation tillage can result in a reduction in the number of irrigation applications and thereby save money. Careful irrigation management will ensure ample water is available for plant use and that nutrients are not lost through leaching. Sensors in various locations in the field help monitor soil water content, making it easier to decide when irrigation is needed.
