SALGADO-GARCIA, Sergio et al. Sustainable fertilization program for plantations of citrus in Tabasco, Mexico. Ecosistemas y recur. agropecuarios [online]. 2016, vol.3, n.9, pp.345-356. ISSN 2007-901X.

Tell the Integrated fertilization (SIRDF) to generate a program for sustainable fertilization in citrus groves of the Savanna de Huimanguilo, Tabasco, Mexico System was used. To apply the SIRDF, local climate data were recorded, they determined the physical and chemical properties of soils and nutrient demand plantations Persian lime and orange Valencia 10 nutrients was estimated based on the yield potential. The fertilization rate for N, P and Κ was determined for each soil subunit of local ecological conditions. The results show that temperatures in the region are suitable for growing citrus fruits, but the low rainfall recorded from February to May is a limiting factor for the production of these crops. Acrisols and Cambisols, both with restricted supply of nutrients for growing the acrisols occupy the largest area: two groups of soils were determined. According to the SIRDF the fertilization of N, P2O5 and K2O for Persian limes are: 207-69-240 in Acrisols Distri-Hiperférricos; 207-69-300 on Acrisols plinthic Lynch; 184-69-240 on Acrisols Humi-plinthic, Acrisols Humi-umbric and Acrisols Umbri-plinthic; 230-92-300 on Acrisols Umbri-gleyic. While in Valencia orange growing the following fertilization were generated: 115-46-120 in Acrisols Distri-Hiperférricos; 138-46-180 on Acrisols plinthic Lynch, Acrisol Humi-Plinthic and Acrisol Humi-Umbric; 138-46-150 on Acrisols Lynch umbric and Acrisols Umbri-gleyic; 115-46-180 on Acrisols Gleyi-plinthic; and 115-46-150 in Acrisols Umbri-plinthic.
