NUTRIENT MANAGEMENT FOR PROPER ALFALFA STAND ESTABLISHMENT

POPESCU C.V, SĂLCEANU C

Abstract


Alfalfa (Medicago sativa L.), is a perennial legume that grows best on deep, well-drained, friable soils.  For a good stand establishment, the seedbed must be smooth, free of weeds and residues and contain readily available nutrients and adequate moisture for germination and emergence. The study emphasizes the importance of the soil analysis for alfalfa crop. Soil samples were collected in 2020 from farm fields located in Hălchiu, Brașov department. Results show that even for weak acidic soils high in organic matter content, the soil’s available phosphorous is 3 - 5 times lower than the recommended guidelines, due to its retrogradation with the soil’s cations – various fertilizing techniques and the use of phosphorous protected fertilizers are required to reach the desired soil levels and to achieve an improved stand establishment and higher yields.
