Description
  • The objective of the proposed multidisciplinary project REK (REserve K) is soil science - geochemical - agricultural research of potassium (K) cycle in our agricultural soils in conditions of permanent negative nutrient balance within cereal agrosystems. Low input of K into agricultural soils by mineral fertilizers compensates insufficiently the output by crops. Thus, K releases from soil supplies (reserve K fixed in fylosilicates, weathering of K feldspars and other soil mineral constituents). However, these soil sources are exhaustible and loss of K availabilness rate can occure after long-term intensive uptake by crops. The ambition of the project is to explore and quantify these soil sources, to evaluate trends of their exploatation and to propose sustainable management of soils limited by the risk of K availability loss.

  • Cílem projektu REK je vyhodnotit stav, vývojové trendy a limitní hodnoty rezerv půdního draslíku v obilnářských systémech a stanovit kritéria a opatření proti náchylnosti půd na kritický pokles jeho zpřístupňování.
Title

  • The project goal - to evaluate the conditions, development trends and limit values of reserves of soil potassium in crop systems and to define criteria of and measures against soil susceptibility to critical decrease of its availability - was achieved. The results allow for the statement that this aim was achieved and the results comply with the project objectives. (en)

Na základě výsledků lze konstatovat, že tento cíl byl splněn a že dosažené výsledky jsou v souladu s cíli projektu. (cs)
