AVITIA-GARCIA, Edilberto et al. Nutrient extraction in strawberry (Fragaria x Ananassa Duch.). Rev. Mex. Cienc. Agríc [online]. 2014, vol.5, n.3, pp.519-524. ISSN 2007-0934.

The strawberry is grown in virtually everyone reaches a production of 2.5 million tons, of which 228 900 t Mexico provides that place it as fourth producer. One of the main problems facing agricultural management is nutrition, so evaluate the total demand for plant nutrients and absorption dynamics is important in determining fertilization plans that allow synchronization between supply and demand cultivation. With the objective of quantifying the nutrient extraction strawberry cv. Roxana, elaborate curves meet nutrient extraction and distribution of dry matter in the plant field-level leaf biomass, crown, stolon, root, flower and fruit was quantified in addition to the removal of N, P, K , Ca and Mg at 30, 62, 124, 184 and 255 days after transplantation (DAT). The stolon accumulated the most biomass (4 736.04 kg ha^-1), the curves of dry matter accumulation and nutrient removal followed a similar pattern. During the development of stolons, flowers and fruits (184 and 255 DAT), one nutrient absorption greater than 50% occurred. The extraction of macro-nutrients in kg ha^-1 of N was 174, P 57.2, K 237.6, 250.9 and 185.7 of Ca Mg.
