Soil seems like a bit of an odd thing to dedicate a day to but 95% of the world’s food is produced in soil. Without healthy soils we won’t be able to grow crops, which is a worrying prospect. This is why many tillage farmers are looking into the best way to prepare soil before and after they harvest their yield.
There are three main approaches to tillage:
1. Conventional tillage
2. Conservation tillage
Conventional tillage utilises machines such as a plough or discs to turn over and loosen the soil after harvest. This can leave the soil exposed to rain and wind, which can lead to erosion of the topsoil that is needed for crop growth.
Conservation tillage takes a different approach. This technique minimises the disruption to the soil when planting seeds. This method of planting helps to prevent soil erosion. By using specialist equipment, the residue of the previous harvest (e.g. plant debris, stalks, etc.) is left intact when the new seeds are planted. This offers additional protection for the soil from erosion, while providing a source of nutrients as the residue will breakdown and compost.
No-till is similar to conservation tillage, but is far less disruptive to the soil. With no-till, no residue from the previous harvest is turned over, and the seed planters only go as deep as they need to for the seed to be planted.
However, from a tillage farmer’s point of view, there are advantages and disadvantages for each option. We have compiled a list of widely thought advantages and disadvantages regarding the types of tillage systems used.
