Too shallow cultlvn I , tton will not bo effective In chocking ovaporation, still ono must know thai tho soil should not bo stirred so dcoi 1 that tho top roots nro cut If this li Ik done tho growth Is at onco checked j! and tho roots nro forced lower tc j I search of supplies. From two to three 1 1 Inches havo boon found the best deptt j I for flat cultivation, where tho ground 1 1 has been thoroughly prepared.
