extraerlo del suelo.\u00bb Si el pH es bajo o la materia org\u00e1nica es insuficiente, la nutrici\u00f3n nitrogenada de la alfalfa puede no estar cubierta.<\/p>\n\n\n\n<p><strong>Limitantes F\u00edsicas y Requerimientos H\u00eddricos<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Compactaci\u00f3n: Un pH \u00e1cido y poca Materia Org\u00e1nica conducen a suelos con agregados inestables, lo que resulta en compactaci\u00f3n.<\/li>\n\n\n\n<li>D\u00e9ficit de Agua: La compactaci\u00f3n restringe la exploraci\u00f3n de ra\u00edces, reduciendo la disponibilidad de agua para el cultivo, especialmente en per\u00edodos de sequ\u00eda.<\/li>\n\n\n\n<li>Excesos de Agua (Anegamientos): La compactaci\u00f3n subsuperficial agrava el da\u00f1o por anegamiento. El da\u00f1o depende de la duraci\u00f3n, temperatura, radiaci\u00f3n, grupo de latencia y estadio de la alfalfa (post-corte es peor).<\/li>\n\n\n\n<li>Eficiencia en el Uso del Agua:La alfalfa tiene un alto consumo de agua y una baja eficiencia de uso (17 a 23 kg Ms\/mm). La mayor parte del consumo proviene de las capas superiores del suelo.<\/li>\n\n\n\n<li>Rol de la Napa Fre\u00e1tica: La napa fre\u00e1tica puede aportar entre el 15% y 25% del agua necesaria si no est\u00e1 a m\u00e1s de 6 m de profundidad (Dardanelli y Collino, 2002).<\/li>\n\n\n\n<li>Importancia del Almacenamiento de Agua: Es \u00abindispensable proveer al cultivo de una buena capacidad de almacenamiento de agua superficial si se pretende buscar acceso a los potenciales de rendimiento.\u00bb<\/li>\n<\/ul>\n\n\n\n<p><strong>Densidad de Plantas<\/strong><\/p>\n\n\n\n<p>Es un factor clave en el rendimiento, ya que la densidad de plantas afecta el rendimiento individual y la persistencia.<\/p>\n\n\n\n<p>Densidades \u00d3ptimas:&nbsp;<\/p>\n\n\n\n<p>Producci\u00f3n \u00f3ptima: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>450 tallos\/m\u00b2.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>500-600 pl\u00e1ntulas a los 90 d\u00edas.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>280-350 plantas al a\u00f1o.<\/li>\n<\/ul>\n\n\n\n<p>Recomendaci\u00f3n de Siembra: Una sugerencia t\u00e9cnica es sembrar 20 kg\/ha, lo que equivale a 450 semillas\/m\u00b2.<\/p>\n\n\n\n<p>Importancia de Alta Densidad Inicial: Una alta densidad de siembra inicial ayuda a mitigar la mortalidad de plantas a lo largo de los a\u00f1os, asegurando una mejor persistencia y producci\u00f3n en el A\u00f1o 1, A\u00f1o 2 y A\u00f1o 3. Una baja densidad de siembra puede llevar a una \u00abDeficiencia de compensaci\u00f3n poblacional\u00bb.<\/p>\n\n\n\n<p>La arquitectura de la planta de alfalfa (altura, disponibilidad de Ms) y la tasa de consumo de los animales influyen en el tiempo de pastoreo y el cumplimiento de los requerimientos de prote\u00edna.<\/p>\n\n\n\n<p>Prote\u00edna: La alfalfa puede tener entre 30% y 9.5% de prote\u00edna dependiendo de su disponibilidad y altura, siendo las partes m\u00e1s altas y j\u00f3venes las m\u00e1s proteicas.<\/p>\n\n\n\n<p>A modo de ejemplo, indic\u00f3 que una vaca de tambo con un requerimiento de 22 kg Ms\/d\u00eda y 18% de prote\u00edna, o una vaca de cr\u00eda con 8 kg Ms\/d\u00eda y 8% de prote\u00edna, tendr\u00e1n tiempos de pastoreo muy diferentes dependiendo de la disponibilidad y altura de la alfalfa.<\/p>\n\n\n\n<div class=\"wp-block-jetpack-slideshow aligncenter\" data-effect=\"slide\" style=\"--aspect-ratio:calc(1024 \/ 576)\"><div
