Effects of potassium on temporal growth of root and shoot of wheat and its uptake in different soils
In a pot culture experiment, the root length density, potassium concentration in crop, and total K uptake by wheat (Triticum aestivum var. HD 2285) at different growth stages (CRIS-Crown Root Initiation Stage, MTS-Maximum Tillering Stage, FLS-Flag Leaf Stage and DFS-Dough Formation Stage) were determined. Wheat crop was grown in 72 pots containing 4.5 kg of three types of soils, namely Alfisol,...
متن کاملCorrection: Soil Penetration by Earthworms and Plant Roots—Mechanical Energetics of Bioturbation of Compacted Soils
Fig 13 is incorrect. The authors have provided a corrected version here. Fig 13. Mechanical energy to create a burrow of 1 m length and 1.2 mm radius as a function of normalized water content using a penetration model and a fracture model. Both models were conducted for a worm of r = 1.2 mm [50] for soils with clay contents ranging from 15–25% [21, 50–52]. open access article distributed under ...
متن کاملSoil Penetration by Earthworms and Plant Roots—Mechanical Energetics of Bioturbation of Compacted Soils
We quantify mechanical processes common to soil penetration by earthworms and growing plant roots, including the energetic requirements for soil plastic displacement. The basic mechanical model considers cavity expansion into a plastic wet soil involving wedging by root tips or earthworms via cone-like penetration followed by cavity expansion due to pressurized earthworm hydroskeleton or root r...
