The agricultural parables of Jesus had economic implications - perhaps that is partly why they gained such an attentive audience. Good seed was expensive; sowing it, was literally throwing it away to be at the mercy of the soil and weather. So, it was especially important that most of the seed went into fertile ground. The financial return would only come after a good crop had been harvested, having survived attacks by rain, drought, cold and heat, as well as from pests and animals.
