Extended waterlogging (WL) conditions in heavily manured soils can change soil phosphorus (P) dynamics. We assessed the effects of soil moisture regimes (field capacity (FC) and WL) and P rates on (i) dry matter (DM) yield and P offtake of ryegrass, (ii)...

The recovery of sludge produced in the wastewater treatment process in WWTPs is often limited by the high content of toxic forms of contaminants of both an inorganic and organic nature. One of the options for the effective treatment of the world?s ever-i...

The sowing-to-harvest period for the medicinal plant Ginseng (Panax ginseng Meyer) is 4?6 years. Although one of the primary soils used to cultivate ginseng in Japan is Andosol, there have been few studies of the changes in the soil?s chemical properties...

To trace the phosphorus (P) and potassium (K) content in flooded rice (Oryza sativa L), 14 rice cultivars commonly grown in the Southern United States were evaluated for their P and K concentration in tissue and grain. Field experiments were conducted at...

A predição da disponibilidade de elementos-traço para plantas com o uso de extratores é dificilmente obtida. Por essa razão, um método de extração sucessiva que simulou a solução da rizosfera com misturas de ácidos orgânicos sintéticos para acessar a dis...
