FIG. 19 Increase in the potassium content of the herbage after a permanent pasture has been ploughed and reseeded

N.B. 1. After ploughing, the old permanent pasture had been sown with a mixture of rye-grass, meadow fescue and white clover and limed at the same time.
        2. The K : Ca ratio averaged 3-00 on the reseeded pasture against 2-20 on the old pasture in the month of May.
        3. The potassium content in the month of May was 4-2% in the reseeded pasture against 2-7% in the old pasture (an increase of 55%).
        4. The pasture was situated at Berlaer.
