En la Sierra Nevada de Puebla, México, los huertos de durazno (Prunus persica L.) presentan problemas de producción relacionados con alta incidencia de plagas (incluye enfermedades), nutrición deficiente e inadecuado manejo de poda, que acentúan el problema de floración precoz en la mayoría de las variedades mejoradas.

Reduction in water content of a soil increased the concentration of ammonium and nitrate in solution, but had no effect on the concentration of phosphate. The corresponding reduction in the quantity of phosphate in solution caused an equivalent reduction in the response of ryegrass to applied phosphate. Keywords: soil solution, soil water content, phosphate, ryegrass, nutrition.
