An agricultural implement includes the calibration of liquid fertilizer distribution for an agricultural implement. The calibration system measures the level of the liquid fertilizer or utilizes a known volume in a container and the pressure of the liquid fertilizer. The system uses the level and pressure to calculate the density of the liquid fertilizer, which helps achieve more consistent fertilizer application. Additionally, the density of the liquid fertilizer can be used to more accurately measure the tank level of a particular tank. The system can include a tilt sensor and valves so that when the agricultural implement is traversing a hill or otherwise rough terrain, the system can accurately measure tank level and selectively draw liquid fertilizer from a particular tank or tanks to mitigate spillage. The system also can measure and monitor the tank level of the tank or tanks and automatically fill the tank or tanks based on the measured tank level.

A seed tube guard for agricultural planters is cast from a high-chrome cast-iron alloy or manufactured from other wear-resistant material. The seed tube guard has a leading front surface, a trailing rear surface, and respective right and left surfaces. A fluid delivery channel is integrated within the body of the seed tube guard between the leading front surface and the trailing rear surface, and between the right and left surfaces. The fluid delivery channel has an entrance and an exit with the exit located below and rearward of the entrance for delivering fluid into a seed furrow ahead of a seed tube exit.
