Effective Manure Application

If crop needs and soil conditions are properly considered, manure becomes a valuable resource. Producers should start by testing cropland soil and manure regularly for nutrient content. Factors to consider when determining application rates include: soil type, acreage, the crop to be grown and the type of manure. The key is to never apply more than is needed. It is also important that manure be applied as closely as possible to the time when the crop can best use the nutrients.

Solid manure should be spread when the soil is dry and completely thawed. In ideal situations, tilling should follow within 24 hours.

By following the above advice, producers ensure maximum benefit and minimum pollution. Keep the neighbours happy - spread at times that are acceptable to everyone.

Liquid manure can also be injected into the soil through units mounted on a bulk tank. Where possible, pre-till tile drained lands before applying liquid manure.

Liquid manure can be injected into the root zone with a flexible-hose system to provide crop needs and reduce risk of run-off. Manure is pumped directly from a liquid storage tank to the manure injector. One advantage of this system is that it is tankless, which can translate into a lower risk of soil compaction.
