Abstract: An includes a soil-sensing arrangement. The apparatus (1) includes a seed-delivery mechanism. The soil-sensing arrangement includes one or more soil-sensing elements. Each of the one or more soil-sensing elements senses one or more conditions of the soil. The one or more soil-sensing elements can take the form of one or more soil-sensing tines (19). In the method, material is delivered to a locally-optimised soil depth LOD. In the method, there is at least periodic sensing of one or more conditions of the soil, and at two or more depths at mutually differing proximities to the locally-optimised depth.
