Effect of soil CaCO3 on root growth and nutrient uptakes
1991
Fuleky, G. | Hussain, S.A.
Pot experiments were carried out with wheat, maize, sunflower, and alfalfa plants on soils containing 0.5, 1, 3, 6, 8, 14, 25 per cent CaCO3. The objective was to determine how the 4 test plants respond to the increasing native CaCO3 content of the soil. The increasing CaCO3 content had the greatest effect on the dry weights of wheat and sunflower, which have the smallest average root weight, and increased their root weights. The Ca content of roots rose significantly with the increase of CaCO3 content in wheat, sunflower, maize and alfalfa plants. The K, Fe, Zn and Cu concentration also decreased in wheat and sunflower.
