All the T&M food plotters should be seeing an improvement in soil health and organic matter. An application of N or blended fertilizer applied after mid-October, along with some legumes in your seed blend, should be fine with only one initial application. Later applications of N will make plots a lil greener but I don’t think the powder is worth the pop. Healthy soil holds N much better and releases to plants as needed. Also the legumes (maintained year round) provides lots of N credit
