Agri-Inject’s innovative Micro-Tube System allows you apply precisely the right amount of liquid in precisely the right place. It’s ideal for use on wheat drills, planters, cultivators and tillage equipment.

Precise placement is key in today’s farming. With the Micro-Tube System from Agri-Inject, you can accurately place precise amounts of fertilizer and crop protection products into the furrow or soil during tilling, planting or cultivating.

The key to our Micro-Tube System is controlled product flow thanks to our great pumps, patented manifolds and patented network of precision-sized tubing.

The cab-mounted controller lets you monitor and adjust the flow rate—on the fly! You can also incorporate a third party multiple rate control system.
