7 Del. Admin. Code § 7103-27.0

Current through Register Vol. 28, No. 4, October 1, 2024

Section 7103-27.0 - Application Equipment

27.1 There are two basic types of irrigation systems: stationary (permanent) and mobile. The stationary system requires a higher initial investment but less annual labor. Mobile irrigation systems may be moved either manually from site to site or may traverse areas of land using a guidance system. Overall application amounts are controlled by the amount of time the system is in operation since the rate of application is generally fixed by the system design and the equipment chosen.

27.2 Drift of spray and aerosols should be minimized by selecting proper equipment, good application times (low wind) and adequate buffer zones. Runoff should be avoided, and this is dependent mainly upon application rate and moisture condition of the soil at the time of application. Uniformity of application can be affected by wind (drift), vegetation and uneven topography. Also, uniformity of application varies with type of irrigation system and sprinklers. Lack of uniformity should be considered in the design to prevent localized ponding or runoff.
