Variation in the mineral and crude-protein content of pastures at Muguga in the Kenya highlands

Abstract
1. Variations in the crude-protein and mineral content of pastures at Muguga are described.2. At all times sodium appeared to be inadequate, and during dry periods phosphorus and crude protein were also apparently deficient.3. Except for sodium and calcium, the amounts present of all substances determined largely depended upon the amount of recent rain.4. The difficulties of interpreting such data have been considered.
