✓ located verbatim in the source · abstract, characters 1194–1320 Other claims from this paper (7) Intervention effect Grass species were the most sensitive to added soil Zn, with maximum dry matter yield decreases greater than 40%. Intervention effect Alfalfa, Alaska pea, tomato, lettuce, spinach and sugarbeet had dry matter yield decreases between 20 and 40% under added soil Zn. Intervention effect Field bean, snap bean, russet potato, white potato, clover and Perfection pea did not undergo a significant dry matter yield decrease under added soil Zn. Observation Zn concentration in tops associated with a 20% yield decrease was 240 ppm for field bean. Observation Zn concentration in tops associated with a 20% yield decrease was 740 ppm for sugarbeet. Observation For most crops, Zn concentration in tops associated with a 20% yield decrease fell in a 400 to 600 ppm range. Observation The most sensitive species tolerated Zn additions of 200 to 300 ppm before undergoing a significant yield decrease.
