La EPA est\u00e1 redactando pautas prometidas desde hace mucho tiempo que los fabricantes esperan que definan m\u00e1s claramente los bioestimulantes, los distingan de los biofertilizantes y bioplaguicidas y traigan legitimidad y aceptaci\u00f3n.<\/p>\n<p>\u201cHay mucho aceite de serpiente en el campo de los bioestimulantes\u201d, dice Justin Smith, vicepresidente ejecutivo de ventas y servicios de campo de Huma Gro, la divisi\u00f3n agr\u00edcola de Bio Huma Netics, en Gilbert, Arizona. &quot;Un nuevo marco regulatorio eliminar\u00eda a las empresas que hacen eso&quot;.<\/p>\n<p><strong>Buenas Experiencias<\/strong><br \/>\nDavid Beaudreau, Jr., director ejecutivo de la Coalici\u00f3n de Bioestimulantes de EE. UU., Una organizaci\u00f3n sin fines de lucro que aborda temas regulatorios y legislativos relacionados con los bioestimulantes, dice que las tasas de adopci\u00f3n de bioestimulantes para el ma\u00edz, la soja, el trigo y el algod\u00f3n en el Medio Oeste estadounidense han aumentado en los \u00faltimos cinco a\u00f1os.<\/p>\n<p>Seg\u00fan un estudio de 2013 de MarketsandMarkets, una empresa de investigaci\u00f3n global, se esperaba que la cantidad de tierra que conten\u00eda cultivos en hileras tratadas con bioestimulantes aumentar\u00eda a nivel mundial de 6,52 millones de hect\u00e1reas en 2011 a 12,745 millones de hect\u00e1reas en 2018, y en Am\u00e9rica del Norte de 1,31 millones de hect\u00e1reas a 2,56 millones de hect\u00e1reas.<\/p>\n<p>\u201cEs cuesti\u00f3n de tiempo antes de que los bioestimulantes tengan un uso m\u00e1s generalizado\u201d, dice Beaudreau. &quot;La industria ha podido demostrar que los productos funcionan y funcionan bien&quot;.<\/p>\n<p>Marcus Meadows-Smith, director ejecutivo de BioConsortia Inc. en Davis, California, dice que su empresa desarrolla bioestimulantes utilizando ciencia s\u00f3lida. Cultiva plantas en diferentes tipos de suelo y bajo diversas tensiones, incluida la falta de agua. Luego, la compa\u00f1\u00eda identifica plantas de alto rendimiento y a\u00edsla microbios que las ayudan a superar la adversidad y prosperar generaci\u00f3n tras generaci\u00f3n.<\/p>\n<p>Desde su fundaci\u00f3n hace tres a\u00f1os, dice Meadows-Smith, BioConsortia ha probado bioestimulantes en pastos, ma\u00edz y varios otros cultivos en Nueva Zelanda, y ha logrado aumentos de rendimiento en el rango de 5% a 7%. BioConsortia ahora est\u00e1 probando ma\u00edz, soja y sorgo en el Medio Oeste.<\/p>\n<p>Carlos Kee, agr\u00f3nomo investigador de Agricultural Sciences Inc. en Dallas, dice que su empresa produce productos bioestimulantes a partir de extractos de plantas inertes. Los productos se han utilizado en ma\u00edz, trigo y soja en Am\u00e9rica del Sur. Kee cree que los bioestimulantes est\u00e1n comenzando a ganar popularidad en los EE. UU.<\/p>\n<p>\u201cMucha gente sinti\u00f3 que si los bioestimulantes no produc\u00edan un rendimiento significativo, no val\u00eda la pena gastar en ellos\u201d, dice Kee. \u201cEsa es una mirada estrecha. Si puede mejorar la salud de las plantas y el suelo, es posible que no aumente el rendimiento este a\u00f1o, pero est\u00e1 ahorrando rendimiento en el futuro &quot;.<\/p>\n<p><strong>La precauci\u00f3n permanece<\/strong><br \/>\nUna colecci\u00f3n de art\u00edculos acad\u00e9micos revisados por pares, proporcionada por Biostimulant Coalition, encuentra que los bioestimulantes ayudan a las plantas a responder mejor al estr\u00e9s, prevenir la erosi\u00f3n del suelo, descontaminar el suelo y el agua y mejorar los rendimientos. Sin embargo, en algunos casos, la investigaci\u00f3n se realiz\u00f3 en laboratorios, no en campos.<\/p>\n<p>Un estudio en Amman, Jordania determin\u00f3 que los bioestimulantes aplicados a los cultivos de trigo entre 1999 y 2003 en Arabia Saudita produjeron aumentos significativos en el rendimiento. Una mirada de 2007 a los bioestimulantes utilizados en el c\u00e9sped y el raigr\u00e1s, presentada por Crop Science Society of America, arroj\u00f3 resultados positivos, pero sin embargo recomend\u00f3 precauci\u00f3n al usar ciertos bioestimulantes.<\/p>\n<p>Un art\u00edculo de enero publicado por Frontiers in Plant Science recomienda un estudio adicional sobre bioestimulantes, y agrega que las &quot;entidades comerciales&quot; probablemente liderar\u00e1n el camino. El art\u00edculo dice que los estudios y avances futuros no ocurrir\u00edan si los bioestimulantes &quot;no se consideraran leg\u00edtimos&quot;.<\/p>\n<p>Allen Philo, vicepresidente de operaciones y ventas de fertilizantes de BioStar Systems LLC en Overland Park, Kansas, se muestra esc\u00e9ptico con respecto a los bioestimulantes. Aunque su empresa se especializa en productos fertilizantes, Philo da conferencias sobre biolog\u00eda del suelo y fertilidad de cultivos. Habl\u00f3 en la conferencia del Servicio de Educaci\u00f3n Org\u00e1nica y Sostenible del Medio Oeste de 2017.<\/p>\n<p>Philo dice que algunos bioestimulantes, como las citoquininas, que fortalecen las ra\u00edces, han sido bien investigados y han demostrado su eficacia. En otros casos, la misma clase de bioestimulantes que promueven la salud de las ra\u00edces puede matar una planta. La dificultad es encontrar las dosis correctas, que vienen en partes por mil millones.<\/p>\n<p>&quot;Tratar de obtener la medida correcta en todo un campo podr\u00eda ser un problema&quot;, dice Philo. \u201cHa habido \u00e9xitos, pero tambi\u00e9n fracasos. Los bioestimulantes nunca reemplazan una buena y s\u00f3lida agronom\u00eda &quot;.<\/p>\n<p>Meadows-Smith sabe que algunas empresas de bioestimulantes no realizan pruebas exhaustivas de los productos en el campo en varios suelos.<\/p>\n<p>\u201cAh\u00ed es donde la pr\u00f3xima generaci\u00f3n de bioestimulantes tendr\u00e1 un gran impacto, en cuanto a mayor eficiencia y rendimiento\u201d, dice Meadows-Smith. &quot;Ya hay empresas con productos y ver\u00e1 m\u00e1s con mejores formulaciones&quot;.<\/p>\n<p><strong>Empoderar a los agricultores<\/strong><br \/>\nEn el estudio realizado por el USDA, que comenz\u00f3 el a\u00f1o pasado y finalizar\u00e1 en agosto de 2019, los investigadores trabajar\u00e1n exclusivamente con agricultores org\u00e1nicos para probar la efectividad de solo seis o siete bioestimulantes que contienen microbios en tomates, calabaza, lechuga, espinaca y zanahorias. Los m\u00e9todos que los agricultores aprenden para evaluar los bioestimulantes se pueden trasladar a los agricultores convencionales y a otros tipos de cultivos y bioestimulantes, dice Kleinhenz.<\/p>\n<p>Adem\u00e1s, el estudio del USDA tiene como objetivo formar una red de agricultores, fabricantes, cient\u00edficos, educadores y consultores que compartir\u00e1n la informaci\u00f3n que obtengan sobre varios productos bioestimulantes.<\/p>\n<p>Kee dice que la investigaci\u00f3n del gobierno mostrar\u00e1 que los bioestimulantes pueden beneficiar a los cultivos en hileras.<\/p>\n<p>Mientras tanto, Smith dice que las tan esperadas pautas de la EPA garantizar\u00e1n que los productos hayan sido revisados, certificados y registrados legalmente.<\/p>","protected":false},"excerpt":{"rendered":"<p>Las pautas regulatorias largamente esperadas junto con la creciente investigaci\u00f3n ayudar\u00e1n a promover un uso m\u00e1s
