Primary heavy duty disc harrows of 265 to 1000 lbs per disc are mainly used to break up virgin land, to chop material/residue, and to incorporate it into the top soil. Lighter secondary disc harrows help completely incorporate residue left by a primary disc harrow, eliminate clumps, and loosen the remaining packed soil. The notched disc blades chop up stover left from a previous crops, such as cornstalks. Disc harrows incorporate remaining residue into the top soil, promoting the rapid decay of the dead plant material. Applying fertilizer onto residue on the surface of the soil results in much of the applied nitrogen being tied up by residual plant material; therefore it is not available to germinating seeds. Disc harrows are also generally used prior to plowing in order to make the land easier to manage and work after plowing. Applying a disc harrow before plowing can also reduce clogging and allow more complete turning of the soil during plowing.
A disc harrow is the preferred method of incorporating both agricultural lime (either dolomitic or calcitic lime) and agricultural gypsum, and disc harrowing achieves a 50/50 mix with the soil when set correctly, thereby reducing acid saturation in the top soil and so promoting strong, healthy root development. Lime does not move in the soil, and this poses a critical challenge to sustainable zero-till farming, especially considering that chemical fertilizers are generally used by farmers around the world.
